CHAPTER 2: SYSTEM DESCRIPTION
2.2 Models Covered by this Guide
There are three models in the DigiVu series, all have QAM output by default, but each has different channel capacity.
FYI: In this guide, reference to DigiVu infers DigiVu 3RU, DigiVu CD 3RU and DigiVu Mini 1RU
unless the model is specically stated. Reference to DVIS is synonymous with DigiVu as these products run on the same rmware..
2.2.1 DigiVu® 3RU
This is the 3RU model with up to 10 channels of SD MPEG­2 encoding or 5 channels of HD/SD MPEG-2/H.264. The output is a single QAM. GbE IP output is available but number of encoded channels is reduced for IP output, as one card slot is used for the IP output card. This is a popular model in applications where up to 10SD/5HD channels of cost effective video are required in commercial sites such as headends, MDUs, stadiums, hospitals and other health care facilities where in-house educational channels are implemented.
Distinguishing Features:
• 3RU Chassis.
• 6 card slots for encoders or I/O cards. (Not all slots can be used for all card types.)
• Up to 10 integrated SD MPEG-2 encoded programs using dual encoder cards.
• Up to 5 integrated SD/HD MPEG-2/H.264 encoded programs.

CHAPTER 2: SYSTEM DESCRIPTION
2.2.2 DigiVu® CD 3RU
This is very much the same as DigiVu with the addition of an integrated channel dropping lter. This is a 3RU model with up to 10 channels of SD MPEG-2 encoding or 5 channels of HD/SD MPEG-2/H.264 where an existing cable TV channel lineup requires that a channel be removed before inserting the new QAM channel. The output is a single QAM. GbE IP output is available but the number of encoded channels is reduced for IP output, as one card slot is used for the IP output card. This is a popular model in applications where up to 10SD/5HD channels of cost effective video are required in commercial sites such as headends, MDUs, stadiums, hospitals and other health care facilities where in-house educational channels are implemented.
Distinguishing Features:
• 3RU Chassis.
• Integrated (optional) Channel Dropping Filter.
• 6 card slots for encoders or I/O cards. (Not all slots can be used for all card types)
• Up to 10 integrated SD MPEG-2 encoded programs using dual encoder cards.
• Up to 5 integrated SD/HD MPEG-2/H.264 encoded programs.
2.2.3 DigiVu® Mini 1RU
This is the Mini 1RU model with up to 4 channels of HD/SD MPEG-2/H.264. The output is single QAM. GbE IP output is available but the number of encoded channels is reduced for IP output, as one card slot is used for the IP output IP card. This is a popular model in applications where up to 4SD/2HD channels of cost effective video are required in commercial sites such as headends, MDUs, stadiums, hospitals and other health care facilities where in-house educational channels are implemented.
Distinguishing Features:
• 1RU Chassis.
• 2 card slots for encoders or I/O cards.
• Up to 4 integrated SD MPEG-2 encoded programs using dual encoder cards.
• Up to 2 integrated SD/HD MPEG-2/H.264 programs encoded.

Figure 2-3: 1RU DigiVu® Mini
2.3 The DigiVu® Encoder
DigiVu series products are headend or network-edge local content encoding devices for digital video networks. They encode local baseband analog content into a digital format at the headend or within a property provisioned with digital only TVs, STBs or DTAs where analog spectrum is not available or where digital content is needed in addition to analog content.
Target applications include:
• Cost-effective encoding, multiplexing & transmission (QAM and/or GigE).
• Headend application of digital simulcast or digital delivery of PEG.
• Hub site specic programming.
• Security or surveillance camera feeds (MDUs, retirement homes).
• Text/character generator or local information channel (hotels, conference centers, gated communities).
• Distribution of ‘in-house’ or private channels throughout a property (e.g., sports stadiums, network studios).
In addition to headend/hub applications, all deployments of digital signals in a modern cable TV system are presented with challenges which did not exist in the former analog deployments. Specic challenges are faced when MDUs and institutions within the cable plant require locally inserted content which must be received by the installed base of cable TV set top boxes (STB). The DigiVu can be used in these properties to encode local analog video cameras, message boards, instructional and advertising channels into HD/SD MPEG-2/H.264 streams. The resulting stream content may be inserted into a blank EIA channel or may perform digital drop and insert into pre-existing clear QAM carriers or also perform Add/Drop Multiplexing within a QAM channel. The exible architecture of the product makes it an ideal candidate for any number of programs that a headend, hub, MDU or similar property is likely to require.

2.4 Key Features
2.4.1 Flexible Digital Program Insertion
Designed for deployment in both RF and IP environments, the DigiVu system is capable of inserting digital programs into an EIA RF channel where there is no pre-existing carrier or it may be used with an integrated channel deletion lter (DigiVu CD Model) and any EIA channel may be effectively removed making way for a new QAM created by the DigiVu. The integrated QAM modulator may be set to any frequency between 54 and 870 MHz (extended range 15 - 975 MHz with some restrictions) in 1 kHz steps and fully supports STD, IRC and HRC channel plans. For IP distribution/insertion installations, Ethernet transport streams may be created as either unicast or multicast, MPTS/SPTS with any address within the valid IPv4 address and port range.
2.4.2 Support for SD/HD MPEG-2/H.264 Encoding
The DigiVu and DigiVu Mini platforms may be ordered with or eld upgraded with card slot plug-in SD or HD video encoders. Each single channel HD plug-in card may be congured for SD or HD and can encode MPEG-2 or H.264 proles. If SD programs only will need to be encoded, there are affordable single and dual channel SD encoder cards available. Both SD and HD programs may be mixed on any output multiplex (IP or QAM) for best bandwidth efciency. Up to 2 HD programs may be multiplexed to a QAM in the DigiVu Mini platform and up to 5 HD programs on the DigiVu platform. For platforms with IP outputs, DigiVu Mini may output 1 HD program while the DigiVu may output up to 4 HD programs.
2.4.3 Gigabit Ethernet Output
The DigiVu systems may be provisioned with an optional gigabit Ethernet output card. The Ethernet card has 2 electrical Ethernet ports (RJ45) as well as 2 SFP ports into which may be installed multimode ber optic SFPs for reliable trunk connection to distribution switches. A variety of SFP interface types such as single mode and multimode ber are supported and may be installed as required by system architecture. The Ethernet output may be provisioned to be the sole output of the unit or simultaneous RF and Ethernet are supported. IP output streams may be provisioned with VLAN tagging and Pro-MPEG FEC. If congured with IP output only(RF Disabled), then the IP programs may be all SPTS streams.
CHAPTER 2: SYSTEM DESCRIPTION
2.4.4 Integrated Add/Drop Multiplexing
Both DigiVu platforms have integral transport stream multiplexers which creates a new QAM or IP multiplex or alternately may be used in an add/drop application along with an optional plug-in demodulator card to insert programs into an existing QAM, clear or encrypted, replacing only the programs that are desired. If the program that is dropped was encrypted, the replacement program stream will be in the clear. The add/drop application utilizes the QAM demodulator to analyze the MPEG stream and selectively insert or “drop and insert” local programs in a exible manner.
2.4.5 Remote Monitoring Via SNMP
The product fully supports Simple Network Management Protocol (SNMP) which allows the monitoring of the built in alarm points by a remote SNMP management console. The available DigiVu MIB may be compiled into the remote Management Console to provide notication of the triggering of alarms either across a private network or the internet if available. Upon triggering of a predened alarm, a trap is automatically sent by the DigiVu equipment to a listening SNMP management console.
2.4.6 Flexible Transport Stream Re-Multiplexing
2.4.7 Scalable Architecture is Field Upgradable
Encoder cards which accommodate one or two channels of SD MPEG-2 or one channel of HD/SD MPEG-2/H.264 encoding may be installed as required so the system may be grown as needs grow. Hot swappable cards make upgrading the DigiVu encoder capability faster while keeping outages to a minimum. The RF Demodulator card may be installed in any available slot as future requirements dictate even if the initial installation did not originally include it. IP output capabilities may also be added when required by installing a Gigabit Ethernet card in slots 2 (DigiVu Mini) or 5 (DigiVu and DigiVu CD).
2.4.8 Mass Deployment and Backup with Conguration Export
The DigiVu platforms allow the operator to export the programmed conguration as a le. The exported le may be used for backup and archive purposes or to allow fast and easy deployment of multiple DigiVu units with similar conguration thus
DigiVu® Series Multichannel MPEG-2/H.264 Encoder/Multiplexer with QAM &/or IP Output - Installation & Operation Manual 2-3
Page 12
CHAPTER 2: SYSTEM DESCRIPTION
saving the time to manually program each unit before deployment.
NOTE: Care has to be taken not to overwrite the existing DigiVu IP address when loading exported settings to remote units. This is avoided with factory default settings but may happen with user congured settings.
2.4.9 IPv4 Network Address Support
All DigiVu platforms support IPv4 IP addressing and maybe congured with any valid IPv4 address to allow access from private networks or from across the internet. For security against internet intrusion, the DigiVu unit forces assignment of a username and password which may be changed at any time.
2.4.10 Optional Channel Deletion Filter (DigiVu® CD)
In applications where all cable plant channels have pre-existing QAM carriers, The DigiVu CD may be congured with an optional channel deletion lter which allows the removal of any EIA channel and all of it’s RF content with minimal adjacent channel affect, allowing a new QAM channel to be inserted.
2.4.11 Powerful GUI
Management and conguration of the DigiVu system is through a built-in web server which presents the conguration pages in an intuitive tabbed format interface. Access to the GUI may be congured to allow remotely connecting across any private network or over the Internet if a connection is made available, usually with a DOCSIS Cable Modem. For internet security, a username and password provides controlled access against unauthorized persons.
2.4.12 Rack Mounting Enclosure
The DigiVu platform is constructed for deployment in a 19” rack mount installation environment. Integral cooling fans allow the equipment to be installed and operate in a wide range of uncontrolled environmental conditions where room cooling is not available.

CHAPTER 3: FIELD APPLICATIONS
3.2 Summary of Insertion Applications
3.2.1 Insertion of a Carrier Into a Blank or Empty Channel Spectrum
It is possible to insert the DigiVu QAM carrier into spectrum space left intentionally blank without the use of a channel deletion lter. Generally the two scenarios for insertion are in between existing adjacent system channels and at the upper edge of the cable system passband.
See “QAM Insertion Without Decoding” on page 3-3
3.2.2 Insertion of a Carrier with use of a Deletion Filter to Remove an Existing Carrier
Using the optional channel deletion lter, the target system channel may be effectively removed to make space for the inserted channel. In this case, adjacent system channels are minimally affected through the DigiVu “Brick Wall” channel dropping lter technology.
See “Insertion into Locally Deleted QAM” on page 3-4
3.2.3 Digital Program Insertion into an Existing QAM with Existing Programs
This application is intended for ‘in the clear’ or encrypted QAM channels that have programming that is able to be sacriced or for QAM channels that are designed for this program insertion feature. Encrypted programs will be replaced with an ‘in the clear’ program.

3.4 QAM Insertion Without Decoding
3.4.1 Insertion Into Empty Channel
DigiVu series products can be used to insert local programming into the cable system where there is empty spectrum (no QAM or analog channel). This can be spectrum in the middle of other channels or above the HFC plant end frequency (at the “band edge”). In these scenarios, a channel is allocated on the system where no carrier is sent from the headend and every property in the system where the DigiVu is installed may insert a QAM without the use of a channel deletion lter. When RF spectrum is available for this application and/or there are a large number of insertion systems installed, the cost of a channel deletion lter may be saved at every property.
3.4.2 Insertion Into Channel at Band Edge
There are two main scenarios for this deployment:
• Regular 870 MHz plant has some empty channels remaining unused just below 870 MHz. The new QAM channel is inserted on one of these empty channels.
• Plant is built to 750 so at least 100 MHz of plant is available with empty channels. The new QAM is inserted in this upper band above the 750 plant.
In each case, some extra loss may be incurred through passives that are near or past their usable bandwidth but in such a case, only a very few passives are affecting the new QAM channel and the DigiVu output may be increased slightly to compensate if required.

3.5 Insertion Into Under-utilized QAM (Add/Drop)
3.5.1 Locally Add/Drop Programs in a QAM
The DigiVu CD can be used to insert local programming into the actual data stream of a QAM by dropping specic programs from an existing QAM channel and replacing them with local content. This application requires optional DEMOD Card and Channel Deletion Filter. In this application, the original system EIA channel is ltered out and a new QAM channel inserted
Figure 3-4: Locally Add/Drop Programs in a QAM
3-4 DigiVu® Series Multichannel MPEG-2/H.264 Encoder/Multiplexer with QAM &/or IP Output - Installation & Operation Manual
Page 23
in it’s place, however, before deletion the incoming QAM channel is demodulated and de-multiplexed. This allows insertion of local content in a more granular manner, right at the program level. Any incoming programs may be selected to be deleted even an encrypted program, and in their place, SD or HD programs may be inserted. Replaced programs will be ‘in the clear’. This has the benet of retaining programs in the QAM that must remain and using the deleted program space to provide the local content to the property. Only content payload is manipulated (dropped/replaced/added). All other data/tables from incoming QAM is passed through without affecting it.
3.6 IP Video Content Insertion
The DigiVu platform with GbE output card may be used to insert IP video content directly to a network switch for transmission on the plant in a hotel or other hospitality environment or transported via Edge QAM and optical for remote delivery.

CHAPTER 3: FIELD APPLICATIONS
3.7 Local Content Back Haul Over IP
DigiVu systems may be used for IP back haul where there is a source of video at a point in the plant such as a remote studio or special program origination location and the video is needed at a hub for reinsertion into the plant. There are two main applications as illustrated in Figure 3-6.
1. Fiber Back Haul
This provides guaranteed signal quality, link speed and bandwidth. In this case, a single mode SFP may be used to transport the IP stream on the ber.
2. DOCSIS modem Back Haul
Not always possible to guarantee link speed and bandwidth which could vary, therefore encoded signal quality must be lower due to lower upstream bandwidth. In this case a DOCSIS modem with high rate upload speed is used to transmit the video over IP to the hub, where it is re-inserted.

• “Equipment Safety Grounding”
• “RF Cable Sheath Grounding”
• “Mounting”
• “Environment Considerations”
• “RF Cabling”
• “Ethernet Network”
• “Installing Modules”
CHAPTER 4: INSTALLATION
4.2 Recommended Installation Environment
Carefully unpack the equipment from the shipping box. If the box or equipment is damaged, notify the freight company to make a damage claim. If you suspect that there is a problem with the equipment that may compromise safe operation, do not install or operate it.
NOTE: This equipment is intended for installation in a RESTRICTED ACCESS LOCATION only. Not for use in a computer room as dened in the Standard for Protection of Electronic Computer/ Data Processing Equipment, ANSI/NFPA 75. This equipment is intended for use in a xed position and should be installed securely before operation is undertaken.
4.3 Equipment Safety Grounding
It is imperative that the chassis be connected to a permanent building ground in a manner that will ensure that the exposed metal parts are constantly connected to ground even when the power cord may be disconnected temporarily. A grounding lug is provided on the front panel to conveniently effect such a connection. The following guidelines are provided to clarify the requirements for the installation to meet UL, CUL and CB standards. The use of the words “Ground” and “Earth” as well as “Grounding” and “Earthing” may be used interchangeably and in this context, have the same meaning.
4.3.1 Connection to Earth
The supplementary equipment grounding conductor is to be installed between the back panel ground connector and earth, that is, in addition to the equipment ground conductor in the power supply cord.
4.3.2 Conductor Size
The supplementary equipment grounding conductor may not be smaller in size than the branch-circuit supply conductors or a minimum #14 AWG. The supplementary equipment grounding conductor is to be connected at the back panel terminal provided, and connected to earth in a manner that will retain the earth connection when the power supply cord is unplugged. The connection to earth of the supplementary grounding conductor shall be in compliance with the appropriate rules for terminating bonding jumpers in Part V of Article 250 of the National Electrical Code, ANSI/NFPA 70, and Section 10 of Part I of the Canadian Electrical Code, Part I, CSA C22.1.
Figure 4-1: Safety Ground Lug
DigiVu® Series Multichannel MPEG-2/H.264 Encoder/Multiplexer with QAM &/or IP Output - Installation & Operation Manual 4-1
Page 26
CHAPTER 4: INSTALLATION
4.3.3 Conductor Termination
Termination of the supplementary equipment grounding conductor may be made to building steel, to a metal electrical raceway system, or to any grounded item that is permanently and reliably connected to the electrical service equipment earth.
4.3.4 Conductor Type
4.4 RF Cable Sheath Grounding
4.4.1 Requirement to Ground the Coaxial Cable Sheath
In addition to the supplementary ground to the equipment, it is also required to ground the sheath of the RF coaxial cable at it’s point of entrance to the building. If the chassis is installed at a location removed from the point of coaxial cable entrance, it is the installer’s responsibility to ensure that the grounding of the sheath has already been performed in accordance with electrical code directives.
4.4.2 Size of Grounding Conductor
The size of grounding conductor and the manner of attachment to the coaxial cable should be in accordance with the national electrical safety regulations in effect in the country in which the installation is located.
4.4.3 Minimize Coaxial Cable Sheath Currents
Care should be taken when grounding the coaxial cable sheath to ensure that circulating currents are minimized to prevent interference on the RF signal. This ground loop condition may be minimized by connecting the coaxial cable sheath grounding conductor to the same building ground point as the chassis safety ground conductor attachment.
4.5 Mounting
4.5.1 Rack Mounting
The chassis is intended to be mounted in a standard 19” EIA equipment rack. A reasonable amount of space will be required in front of and behind to allow installation and servicing. The equipment is designed with fan forced cooling which exhausts to the top and side of the unit. Avoid blocking airow at the top and sides and mount in such a manner to provide a source of ambient cool air at the front fan air intake grill. Provide at least one open rack space above the chassis. Consider also that the site technician will need access to the front and back of the unit for accessing connections, maintenance and conguration when determining the best mounting location.
4.5.2 Mounting Precautions
FYI: See “Equipment Safety Grounding” on page 4-1 for detailed information on grounding.
1. Elevated Operating Ambient:
If installed in a closed environment that may exceed room ambient temperature, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature specied (50°C).
2. Reduced Air Flow:
Installation should allow at least 2” spacing around the equipment to ensure that airow required for proper operation is not compromised. At least one blank rack space above the unit should be allowed.
3. Mechanical Loading:
Mounting of the equipment should be according to the installation instructions so that a hazardous condition is not created due to improper mechanical loading. Do not use the DigiVu to mechanically support other equipment.
4. Circuit Overloading:
Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuit will have on over-current protection and supply wiring. Consider equipment nameplate ratings when addressing this concern.
5. Reliable Earthing:
The chassis must be connected to a reliable ground or earth connection with an adequately sized copper conductor.
See “4.3 Equipment Safety Grounding” on page 4-1.
4-2 DigiVu® Series Multichannel MPEG-2/H.264 Encoder/Multiplexer with QAM &/or IP Output - Installation & Operation Manual
Page 27
4.6 Environment Considerations
4.6.1 Ambient Temperature
The chassis must be installed in a room where the ambient air temperature does not exceed +122°F (+50°C). This is a maximum temperature that must not be exceeded but the preferred temperature range is one where people feel most comfortable.
4.6.2 Non-condensing Environment
The environment must be non-condensing. This means that a relative humidity of less than 95% must be maintained. Lower humidity is better and the preferred humidity range is one where people feel most comfortable.
4.6.3 Fan Control
The equipment is designed to operate to specication in an ambient room temperature of 0°C to +50°C (+32°F to +122°F). Sufcient airow through the unit must be maintained regardless of the mounting location. It is imperative that other equipment or materials of any type do not block free airow at the front and top/back of the chassis. There are no internal air lters so there is no need to provide ongoing maintenance of lters.
4.7 Provisioning Electrical Power
4.7.1 Power Cord Protection
Measures must be taken during installation to route or arrange the power supply cord to prevent physical damage to the cord and to avoid the possibility of future damage occurring. The power supply cord shall be installed and routed such that, throughout it’s length, the cord and it’s points of connection are not strained in any way.
CHAPTER 4: INSTALLATION
4.7.2 Power Cord Attachment:
The power supply cord shall not be attached to the building surface, bundled with audio, video or RF coaxial cables, nor run through walls, ceilings, oors and similar openings in the building structure.
4.7.3 Provision of Electrical Power Outlet:
An electrical power outlet of appropriate type and rating shall be provided near the location where the chassis is installed such that the provided power supply cord may be routed in an appropriate manner, without the use of extension cords, between the receptacle and the chassis. Alternately, the chassis shall be installed in close proximity to an existing electrical outlet such that the requirements of this paragraph are achieved.
4.7.4 IEC Power Input Cord
The power input receptacle is a standard IEC connector similar to that commonly used on computers and monitors. The power cord provided is dependant on the shipping address of the equipment. If shipped in North America a cord with a NEMA 5-15 grounded plug for 115 VAC is provided. If it is necessary to operate the equipment on 230 VAC, the installer must obtain an IEC cord with a NEMA 6-15 grounded plug for use in North America. This may be obtained from ATX Networks or locally. If shipped outside of North America, the equipment will be shipped with an IEC cord set appropriate for the locale.
4.7.5 Input Power Requirements
When installing equipment, it is the responsibility of the installer to determine that sufcient capacity is available in the electrical circuit feeding the unit to avoid overloading the supply circuit. Each model will require power according to it’s specications to be supplied from a properly grounded outlet. The installer should determine that the power outlet, its wiring and receptacle is in compliance with the local electrical codes.
4.7.6 Input Power
4.7.7 Input Voltage Range
The equipment is supplied with an autosensing switching type power supply which can operate on input voltages from 90 VAC to 264 VAC. There is no need to congure the power supply to operate on any voltage within this range.
4.7.8 Fusing
The internal power supply is protected from over current conditions with a slow blow fuse. Replace with similar type and rating to avoid over-current circuit damage. The following table describes the fuse if replacement ever becomes necessary.

4.8 RF Cabling
RF cabling to the chassis should be either RG6/u or RG59/u style double or triple shield coaxial cable of a type UL approved for Cable TV applications. There is no restriction on using RG6/u cable on the F Fittings. Connectors should be very lightly wrench tightened according to Cable Service Provider’s company policy.
NOTE: Final connection of the RF output to the distribution network should only be completed when the installer has completed conguration. An incompatible conguration, if it was installed or congured elsewhere, may create a situation where output RF Levels are incompatible with the premises. This may result in unintended service outages.
4.8.1 RF Output Connector
The accompanying graphic illustrates the rear panel. A diagram, “Simplied Block Diagrams” on page 2-4 may be referenced for details of interconnections.
Fuse Replacement Criteria - All Models
4.8.2 RF Input Levels
If the DigiVu chassis has been tted with a demodulator module, then the input signal level presented to the RF input of the module must be in the range of +5 to +14 dBmV per digital carrier as measured with a digital eld meter. If local conditions dictate that a higher or lower signal level is available, the installer must install appropriate external attenuation or may install a coupler to ensure the input specication is met. External RF attenuators and couplers that may be necessary depend on site conditions and are not supplied.
4.8.3 RF Output Level
The RF output connector is 75 Ω “F” Type female. The output level from the QAM modulator is 57.5 +/- 1.5 dBmV. The GUI provides an internal adjustable attenuator of up to 26 dB in 1 dB steps to reduce this level to match application specic RF levels. Try to adjust the modulator output QAM level to closely match adjacent channels on the nal system combining network.
4.9 Audio & Video Connections
4.9.1 Video Cable Recommendation
Coaxial
It is recommended to utilize double or triple shielded 75 Ω coaxial cables with BNC or RCA (depending on encoder card) connectors or adapters for video signals. UL approved coaxial cables that are in general use in Cable TV systems will usually be satisfactory. Observe re and smoke rating of cables and the installation environment to ensure compliance with all local codes. Cables shall be routed and connectors and adapters attached such that terminal connections are not strained.
VGA
Usually a pre-manufactured VGA cable is used if this is the input signal type. Lengths up to about 50 meters may be available but specify a plenum rated cable if the cables of this length which leave the equipment room will be installed. Cables shall be routed and connectors and adapters attached such that terminal connections are not strained.
Figure 4-2: DigiVu® Rear Panel RF Output
4.9.2 Video Port Connectors
The MPEG-2 encoders are provided with a BNC female connector for SD video input . For convenience a BNC male to RCA female adapter is provided on each video input port as this is a common requirement in many installations.
The MPEG-2/H.264 encoders are provided with 3 x RCA female connector (component) and DE-15 female connector (VGA).
4-4 DigiVu® Series Multichannel MPEG-2/H.264 Encoder/Multiplexer with QAM &/or IP Output - Installation & Operation Manual
Page 29
4.9.3 Video Input Levels
Video Input level is expected to be 1 volt P-P although a higher and lower signal voltage may be tolerated by adjusting the video level control in the GUI. See “Brightness: [0-255]” on page 6-6 for a possible work around for low level video.
4.9.4 Audio Cable Recommendation
It is recommended to utilize double or triple shielded 75 Ω coaxial cables with RCA connectors or adapters for audio signals. UL approved coaxial cables that are in general use in Cable TV systems will usually be satisfactory. Observe re and smoke rating of cables and the installation environment to ensure compliance with all local codes. Cables shall be routed and connectors and adapters attached such that terminal connections are not strained.
4.9.5 Audio Port Connectors
The Audio connectors provided are RCA female type, except L/R baseband audio on HD/SD card which uses a TRS 3.5mm female connector. This card is shipped with a 3.5mm female to 2 x RCA female adapter. Many adapter types are available to convert these RCA connections to the type that may be encountered at a property. Use good quality shielded cable for all audio applications.
4.9.6 Audio Input Impedance & Level
The audio input is high impedance unbalanced. Be sure to match the audio source to the DigiVu audio connection. Usually double or triple shielded 75 Ω coaxial cables may be used with satisfactory results. If balanced audio is encountered it is often possible to obtain good results by using only the + side of the feed.

5.3 Minimum Computer Requirements
The computer used to access the DigiVu conguration settings is referred to as the Management Computer. It is recommended that the Management Computer meet the minimum requirements listed below. ATX Networks does not endorse the use of any specic operating system software however the listed combination of software has been thoroughly tested with the DigiVu and is known to work without issue. The operator is free to utilize whatever software combination is desired, however the responsibility to ensure correct operation of the alternate software is his/hers alone.
NOTE: The extensive use of Java script in the DigiVu interface may cause web browsers other than Internet Explorer® to incorrectly or incompletely display DigiVu web pages.
5.3.1 Recommended Computer
• Computer running Windows® or other OS.
• Ethernet Network port available.
• Web browser.
• Adobe® Reader® for reading this manual.
5.4 Connecting to the GUI
Conguration of the DigiVu requires a laptop or desktop PC running Microsoft Windows or other OS with an available Ethernet network port (the Management Computer). If connecting directly to the unit, the Management Computer must be set to operate on the same subnet as the DigiVu for access to the DigiVu GUI.
The following procedures are for Microsoft Windows XP and a default IP address setting on the DigiVu of 192.168.0.23.

CHAPTER 5: THE GUI
FYI: If you are using a different Operating System or the network address on the DigiVu has been changed from default, adjust the procedures to suit the address or software you are using.
1. Connect the Management Computer’s Ethernet adapter to the DigiVu’s Ethernet port using a Cat5e cable, see Figure 5-6. Link lights should illuminate indicating that the cable connection is correct and working.
2. Set the Management Computer’s Ethernet interface to a static IP address on the 192.168.0.x subnet, as described in Figure 5-3.
Figure 5-3: Setting the Management Computer IP Address
FYI: If the Management Computer currently has network settings that will need to be used again after the DigiVu system is congured, this would be a good time to makes note of the current settings if you don’t already know them, so the network adapter may be readily returned to these values again.
a) From the Control Panel, open ‘Network Connections’ and select the connection associated with the
wired Ethernet adapter to be used for connecting to the DigiVu (e.g., Local Area Connection).
b) Right click on the connection then select Properties.
c) Select ‘Internet Protocol (TCP/IP)’ and click Properties.
d) Click the selection box beside Use the following IP address.
e) In the ‘IP address’ eld, enter 192.168.0.x (where x represents any number from 1-253 except 23).
f) Click in the ‘Subnet mask’ eld and the subnet 255.255.255.0 is automatically entered.
g) Click OK and then OK again in the previous window.
3. On the Management Computer, open a web browser and enter http://192.168.0.23/site in the address eld.

5.5 Connecting to the Management Computer
The DigiVu and DigiVu CD 3RU chassis are both provided with a 10/100 Base-T Ethernet network port on the rear panel for the Management Port. The 1RU DigiVu Mini has the port on the front panel, shown in Figure 5-6. This port is for connecting to the GUI for initial conguration and ongoing monitoring and maintenance.
Figure 5-6: DigiVu® Mini Connected to the Management Computer
The management port is DTE, similar to a PC Ethernet port. A crossover Ethernet cable, provided with the equipment on shipment, will be required to connect the Ethernet port directly to a PC.
The network port will automatically negotiate a speed of 10 or 100 Mbps depending on the capabilities of the PC network port. A light next to the DigiVu Ethernet port will illuminate amber when a link is negotiated.
FYI: If connectivity problems between the PC network port and the DigiVu occur, (Ethernet link light does not illuminate) check to be sure that you are using a known good network cable.
If the equipment is to be connected to a local cable modem for remote conguration or monitoring, a standard Cat5e or better type cable will be required for the connection to the modem. The cable required for connection to the cable modem is normally supplied with the modem.

5.6 Connecting to a Local Cable Modem
The following procedure allows remote management using a cable modem for internet connectivity.
5.6.1 Install and Connect the Modem
1. Connect the cable modem RF input to a source of cable TV RF signals of the appropriate level.
2. Verify that the modem completes registration to the DOCSIS carriers (LED indication). If the cable modem does not lock into the DOCSIS carriers, verify that the signal at the RF input port is sufcient.
5.6.2 Log into the GUI
It is rst necessary to connect the Management Computer directly through a crossover network cable to the front or back panel management port depending on the model, and congure the DigiVu IP address for remote management. See “Connecting to
the GUI” on page 5-2 for details on logging into the GUI.

CHAPTER 5: THE GUI
5.6.4 Static IP Address Assignment
If the DigiVu can be plugged directly into an Ethernet based device, a router, switch, cable modem, that supports clients with public static IP addresses (or static IP addresses that may be routed to the public internet), the following procedure can be taken to assign a static IP address.
1. Open the ‘Maintenance’ tab in the GUI and scroll to the ‘Network Settings’ section.
Figure 5-8: Conguring Management Ethernet for Static IP Address
2. Fill in the following elds with appropriate values:
◦ Static IP Address - An IP address assigned to the unit by the network administrator.
◦ Subnet Mask - The mask to match the IP address assigned to the unit by the network administrator.
◦ Default Gateway - The IP address of the router assigned by the network administrator.
3. Click ‘Set Network’.
4. In the conrmation window that appears, click ‘Yes’ to conrm the change to the network parameters.
5. The unit will reboot and fans will shut down, then restart.
6. An error message will be displayed in the browser. If Internet Explorer is being used, a message box displaying request failed. http status 12152 for 1 second then another error message. The error messages indicate that the DigiVu network settings have been modied and therefore connectivity has been lost.
7. Wait 2 minutes then open a new browser session with the GUI using the new IP address that was entered.
5.6.5 Connecting Remotely
In order to connect to the DigiVu chassis remotely you need the IP address that the network port has been set to. Depending on the method of setting the IP address, acquire the address in the following ways. If you know the address skip to “5.6.4 Static
IP Address Assignment” on page 5-6.
5.6.6 Dynamic IP Address Acquired via Cable Modem
In order to reconnect to the GUI after it is connected to a cable modem, it is necessary to determine the IP address the unit has acquired from the DHCP server. There are two ways to achieve this:
• Get it from the DHCP Server:
Log into the appropriate billing system interface and access the account associated with the cable modem being used. The account can typically be found by searching according to cable modem MAC address, which is labeled on the modem. Once you can access the cable modem account, verify that a client with the MAC address noted above, see the section “5.6.3 Congure the DigiVu® IP Address for Remote Management” on page 5-5 is listed as connected in the cable modem client table. Record the IP address assigned to the DigiVu unit MAC address in the cable modem client table.
• Get it from the Cable Modem:
Log into the cable modem interface if it is accessible. Each cable modem has a built-in web server to allow troubleshooting and this interface will display the acquired IP address.

Page 37
FYI: In some systems, the time for the billing or modem management system to update with the most recent cable modem client table information may take a few minutes to a few hours. If you have alternative means to nd out the IP address assigned to the client with the DigiVu MAC address more rapidly, you can save time as the DigiVu is available for remote access as soon as the new IP address is acquired, regardless of whether the billing or modem management system has this information.
Once you have the assigned public IP address of the DigiVu:
1. Open an Internet Explorer web browser and in the address bar enter ‘http://xxx.xxx.xxx.xxx/site’ replacing the x’s with the IP address of the unit.
2. When the login screen appears, enter the Username and Password for the unit.
Username Password
3. Upon validation of the login and password, the GUI opens and displays the ‘DVIS Settings’ page. The unit is ready to be managed remotely.
5.6.7 Static IP Address Assigned
1. Login to a computer with internet access. If you are using the same computer that was used for direct connection to the DigiVu, remember to restore the computer’s network settings to the appropriate values (the settings used prior to changes made for connection to the DigiVu or other settings, as appropriate).
2. Open a new Internet Explorer browser window to establish a fresh internet session entering the IP address of the DigiVu GUI in the address window.
3. You should be presented with the following screen on the left, prompting you to log in:

6. Encoder Settings Tab
In this chapter we detail the conguration controls which are used to adjust settings to achieve the encoder performance that is required. All GUI settings are discussed along with limits and some suggestions as to what values are most applicable and why. With the selection of some encoder types it will be seen that some parameters are greyed out, meaning that these parameters are either not relevant or are preset. Reference to DigiVu infers both DigiVu and DigiVu Mini unless specically stated.
FYI: In this guide, reference to DigiVu infers DigiVu 3RU, DigiVu CD 3RU and DigiVu Mini 1RU

CHAPTER 6: ENCODER SETTINGS TAB
6.2 SD Encoder Cards
There are three types of SD encoder available, briey described below. The selection of encoder card is principally based on functionality required. The type of hardware encoder that is plugged in will automatically be detected and reported in the GUI.
The options presented to be congured will be adjusted to only those available to the specic installed encoder.
6.2.1 NXP
• Available as single and dual channel encoder card.
This is the legacy SD MPEG-2 encoder model for both ETSI (European standard) and ATSC (North American standard). It is no longer available for purchase but may be encountered in existing installations. This encoder supported fewer video resolutions and audio bit rates than the current VWEB encoder. It also did not support Closed Captioning.
6.2.2 DV1CE & DV2CE
• Available as single and dual channel encoder card.
This is the currently shipping ATSC SD MPEG-2 encoder with support for a wide array of video resolutions and AC-3 audio bit rates. There is support for ATSC closed captioning which may be turned on or off as required.
6.2.3 DV1CEM & DV2CEM
• Available as single and dual channel encoder card.
This is the currently shipped PAL SD MPEG-2 encoder with support for a wide array of video resolutions and MPEG-1 audio bit rates.
6.3 HD Encoder Card
There is a single channel HD encoder available. The type of hardware encoder that is plugged in will automatically be detected and reported in the GUI. The options presented to be congured will be adjusted to only those available to the specic installed encoder.
6.3.1 DV1HDA
• Available as single channel encoder card only.
This single program HD/SD encoder supports both MPEG-2 or H.264 encoding. The following table outlines the multiplexing capabilities for HD encoded programs per QAM channel or IP multiplex.
FYI: It is important to note that the Video Resolution of this card must be set to match the input source.
FYI: The ability to output 5 HD programs per QAM depends on encoding format and bit rate. The DigiVu and DigiVu CD may be limited to just 2 HD programs per QAM with a high encoder bit rate setting.
Maximum Programs Encoded per Platform
Platform QAM Output IP Output
DigiVu® 3RU 5 HD Programs 4 HD Programs
DigiVu® CD 3RU 5 HD Programs 4 HD Programs
DigiVu® Mini 1RU 2 HD Programs 1 HD Program
6.4 Input and Output Cards
There are other cards available that may be used for some specialty applications. The cards are briey described below.
6.4.1 DVDMQMB & DVDMQMAC QAM Demodulator
This card must be used if an add/drop conguration is required. May be installed in any card slot except #1.
6.4.2 DVGIGE Gigabit Ethernet Output
This card is used in applications where Ethernet output of the DigiVu is required and is supported only in specic slots. The recommended slot to use is always the highest available which will usually be slot #2 in the DigiVu Mini 1RU model and slot
6-2 DigiVu® Series Multichannel MPEG-2/H.264 Encoder/Multiplexer with QAM &/or IP Output - Installation & Operation Manual
Page 41
#5 in the DigiVu and DigiVu CD 3RU models.
6.4.3 DV1HDA Distribution Amplier/ 2-Way Baseband A/V Splitter
The splitter is used in applications where only one video/audio source is available but two encoders or one encoder and one analog RF modulator must be fed by the same source. This splitter creates two baseband A/V outputs from one input. This may be used in any available slot but should be installed in the AUX slot in the DigiVu and DigiVu CD 3RU models. The splitter card is an un-managed card (no settings to be adjusted or changed in the GUI) and only requires power and that is the purpose of the AUX slot.
6.5 Encoder Settings Tab
This page displays the conguration of all of the installed HD/SD MPEG-2/H.264 video/audio encoders and allows adjustment of the currently set values. If other types of cards are installed, such as a demod or gigabit Ethernet card, they will be reported under the heading “Encoder Type” but are not congurable on this page, so ignore the settings reported below these cards. The Encoder Number control is used to select the encoder that is desired to change the settings for, then as each encoder is selected by way of the drop down dialog box, the appropriate encoder port is highlighted in the Ports View. The general process for making changes to an encoders settings is as follows:
6.5.1 Port Numbering Convention
DigiVu 3RU Models
Each DigiVu physical encoder slot is assigned a pair of port numbers in the GUI and there can be up to two encoders per installed card. The rst physical slot is assigned ports 1 & 2, the second slot is assigned ports 3 & 4 etc. If an encoder card has only one encoder installed, the port that would have been occupied by the second encoder is reported in the GUI as “None”.
DigiVu Mini 1RU
The Mini is slightly different than the 3RU models in that the second physical card slot is associated to the GUI ports 5&6. This is for support of the DVGIGE card that is not supported in Ports 3&4. In this case, ports 3&4 will be reported in the GUI as “None”. If a DVGIGE card is installed in a 1RU model, it would always be installed in slot 2.

Select the encoder port number from the drop down box representing the encoder that you wish to adjust the settings for. The applicable/selected column becomes highlighted in Ports View.
6.7.2 Encoder Type:
In the ‘Ports View’ section, the type of encoder installed is indicated. The types of SD encoders that may be encountered here were discussed in “SD Encoder Cards” on page 6-2 as well as the type of HD encoder in “HD Encoder Card” on page 6-2. If another type of card is installed this will also be identied. These cards were briey discussed in section “Input and Output
Cards” on page 6-2. Disregard the conguration reported for all cards except encoders. The possible card types that may
be reported here are:
• VWEB_NA (NTSC Video SD MPEG-2, AC-3 audio)
• VWEB_NA_1 (NTSC Video SD MPEG-2, AC-3 audio)
• VWEB_EU (PAL Video SD MPEG-2, MPEG-1 L2 audio)
• VWEB_EU_1 (PAL Video SD MPEG-2, MPEG-1 L2 audio)
• NXP (Legacy NTSC/PAL Video MPEG-2 w/AC-3 & MPEG1 audio)
• ETH1000 (GigE Output Card)
• AN_HD (HD/SD MPEG-2/H.264 encoding)
• Demod_nxp (Legacy Demod Card)
• Demod_dnq (Demod Card)
CHAPTER 6: ENCODER SETTINGS TAB
Figure 6-3: Encoder Setting
6.7.3 Detect Encoder (Control)
• Slot Previously Empty
If an encoder slot was previously empty and a new encoder card was hot plugged into the slot, the GUI must be made aware of the change as it will not take any action without instruction. Click the Detect Encoder button to force a detection of the encoder card just installed. The control will be greyed out on any encoder selected that has already been detected.
• Slot Previously Occupied
If an encoder slot was previously occupied and a different card was hot plugged into the slot the DigiVu must be made aware of it but the control is greyed out. In this case, click the Refresh All Ports button at the bottom of the GUI page to force the DigiVu to detect the encoder card just installed. The control will be remain greyed out on any encoder selected that has already been detected.
6.7.4 Encoder Active:
This check box lets you switch each encoder on and off. On the right side of the page in the Ports View display, encoders are shown as active or inactive.
6.8 Input Parameters
This group of settings are for conguration of any input variables on some encoders, such as Video Input on the HD encoder. Some of these are preset by the GUI depending on the encoder card and in this case, is for information only.
6.8.1 Input Video Standard:
Automatically selected as NTSC or PAL as appropriate for the SD encoder card installed. If an HD encoder is installed, this displays AN_HD.
Figure 6-4: Input Parameters
6.8.2 Audio Input:
Selects between input types if more than one is available for the selected card. For the HD encoder the selectable input types are L/R UB analog audio or S/PDIF. The S/PDIF input supports AC-3 only and PCM is not supported. For the SD encoders the input type is L/R UB.

Page 44
CHAPTER 6: ENCODER SETTINGS TAB
6.8.3 Video Input:
Selects between input types if more than one is available for the selected card. For the HD encoder the input types are VGA , and Component. For the SD Encoders the input type is Composite.
6.8.4 Audio Sampling Rate:
This value is preset at 48 kHz and is the number of samples per second (in kHz) taken from an analog signal to make a digital signal.
6.9 Output Parameters
This group of conguration settings affect the video and audio program stream properties.
6.9.1 Video Codec:
For encoder cards with more than one type of encoding prole, this allows selection of the required prole. For the HD encoder card the prole types are MPEG-2 and H.264. For the SD encoders, the prole is MPEG-2 for ATSC and ETSI.
6.9.2 Video Rate: [1000-20000]
FYI: When the unit is operating in Add & Drop Mode, this setting is
greyed out as it is set in the conguration view “Demod & Mux Settings”
on page 10-4
The video program elementary stream bit rate is entered in kbps and must be between 1000 and 8000 for SD programs, between 1000 and 20000 for H.264 HD programs and between 1000 and 20000 for MPEG-2 HD programs. Increasing the bit rate increases the resulting picture quality but consumes more bandwidth. The entered value must be balanced against the number of other programs in the output MUX and the total amount of room within the MUX for each program.
FYI: Although the HD resolution support is able to be set as low as 1000 kbps, this low bit rate will not result in suitable quality and is only intended for the SD resolutions that this HD card supports. Suitable quality for HD programs will be obtained at a bit rate of 6000 kbps or higher.
6.9.3 VBR:
Not functional at this time. Future implementation.
6.9.4 Video Resolution:
Video resolution refers to the number of discrete picture elements (pixels) in each horizontal line and the number of displayed horizontal lines in the picture. (e.g. 720 pixels per line x 480 lines). The available video resolution settings depend on the type of encoder installed. Higher picture resolutions require a higher video bit rate for the same picture quality and conversely, a lower resolution picture can be encoded with a lower bit rate. Depending on the quality required and the resolution of the source video, such as a lobby camera, lowering the resolution and bit rate may be used and more channels may be added in available bandwidth. For all SD encoder cards, the Video Resolution setting determines the output resolution, however, for the HD encoder card (for HD encoding resolutions), the Video Resolution setting must be set to match the input resolution.
FYI: It is important to note that the Video Resolution of the HD encoder card (for HD encoding resolutions) must be set to match the input source resolution.

6.9.7 Saturation: [0-127]
This dialog allows modication of the video signal to increase or decrease color saturation. There are 128 levels available (0-
127) The default value is preset at 66. This setting should not normally require changing. For HD this is not applicable.
6.9.8 Enable Audio:
The audio codec may be disabled if the specic application of the DigiVu does not require an audio program such as a lobby camera. Disabling the audio codec will result in silence at the receiving TV. Use the drop down box to select the required setting. The default is Enable.
6.9.9 Audio Codec:
This setting is automatically set to the value appropriate for the detected SD encoder card. A codec converts an audio baseband signal to a specic streaming audio format. The AC-3 codec supported in DigiVu is 2.0 (two channel stereo). The supported audio codec depends on the encoder card installed.
6.9.10 Audio Rate:
This drop down displays the audio bit rate options available for each installed encoder. This is the data rate at which an audio signal is encoded. Each encoder supports commonly used bit rates which range from 192 - 384 kbps. The recommended audio rate is 192 kbps for stereo audio.
6.9.11 Audio Volume:
This control inuences the volume level of the incoming baseband audio signal into the encoder card. This value typically does not need to be changed from it’s default value but some guidance is provided if audio volume is not satisfactory with standard settings.
Setting Audio Volume
• SD Encoder - The scale is 0 - 255 with the default setting of 150.
The value represents a relative volume output and is not an absolute level. If the volume as heard on a TV or other receiving device is too high or too low, increase the value to increase the output volume or decrease the value to decrease the output volume. Be careful to not increase the volume excessively as the encoding of extreme high volumes will cause instability.
• HD Encoder - The scale is in dB with a default setting of 0 dB.
The value represents a relative volume output and is not an absolute level. If the volume as heard on a TV or other receiving device is too low, increase the setting to a positive number to increase the output volume. An increase of 10 dB will double the output volume. Be careful to not increase the volume excessively as the encoding of extreme high volumes will cause instability.
CHAPTER 6: ENCODER SETTINGS TAB
6.9.12 AV Sync:
This adjusts audio/video lip-sync up to +/- 2000 ms if program audio is not in synchronization with the video. With each adjustment of this value, click Add to Table then Submit all Ports for the value to become effective, see Figure 6-2 for guidance. If needed, the correct value is found by trial and error.
6.9.13 Offset_X:
This setting allows the adjustment of the horizontal position of VGA input signals only. With each adjustment of this value, click Add to Table then Submit all Ports for the value to become effective, see Figure 6-2 for guidance. The picture may be shifted by +/- 50 pixels.
6.9.14 Offset_Y:
This setting allows the adjustment of the vertical position of VGA input signals only. With each adjustment of this value, click Add to Table then Submit all Ports for the value to become effective, see Figure 6-2 for guidance. The picture may be shifted by +/- 50 pixels.
6.9.15 VBI Value:
This tick box enables Closed Caption (CC) support in the Vertical Blanking Interval (VBI). Only the value appropriate to the installed encoder will be available in the drop down. The video encoders do not create a closed caption, they capture existing closed captions on incoming video and convert them to a digital format.
• ATSC_CC Enables the processing CC data for ATSC (In cards VWEB_NA, VWEB_NA_1, DV1HDA).
• ETSI_CC Enables the processing of CC data for the ETSI (not currently implemented).
• NONE Disables the closed caption function.

6.10 Program Identication
This section allows conguration of the program specic settings of the MPEG­2 transport stream. The PID values may often be left at their default values. The ‘Program Number’ must be set appropriately. The remaining parameters may or may not need to be set as it is application specic.
6.10.1 Program Number: [1-65535]
This is the MPEG-2 Program Number that identies a program from others within a multiplex and is used to allow selection and decoding at the receiving device. It is a unique number that is assigned to each program within a multiplex and may require setting according to the system channel map. The decoding device may display this program number for program selection.
6.10.2 Virtual Major Channel:
FYI: For virtual Major/Minor channels to be detected and acted upon by an appropriate end user device, it is required to enable the ‘PSIP’ feature on the MUX tab. See “7.4 DVB® SI Settings” on
page 7-2 to enable this feature.
FYI: This parameter is only detected or used by end user devices that support PSIP tables.
Figure 6-6: Program Identication
For a program in a QAM channel, this is the major channel which is often also the EIA channel.
6.10.3 Virtual Minor Channel:
FYI: For virtual Major/Minor channels to be detected and acted upon by an appropriate end user device, it is required to enable the ‘PSIP’ feature on the MUX tab. See “7.4 DVB® SI Settings” on
page 7-2 to enable this feature.
FYI: This parameter is only detected or used by end user devices that support PSIP tables.
For a program in a QAM channel, this is the program number within the previously dened Major channel. This is the program number within the multiplex.
6.10.4 Source ID:
A source ID may be assigned here if the DigiVu application required it. This is not mandatory.
6.10.5 Program Name: [Max. 12 Chars]
FYI: For Program Name to be detected and acted upon by an appropriate end user device, it is required to enable the DVB-SI feature on the MUX tab. See “7.4 DVB® SI Settings” on page 7-2 to enable this feature.
The name (up to 12 characters) assigned to a program may be entered here. To enable, it is required to select the DVB-SI option in MUX page. This name may or may not be supported in the end customer decoding device.
6.10.6 Video PID: [21-8190]
The video PID (Packet Identier) is a decimal number that uniquely identies a video transport stream in an MPEG-2 transport stream so that it can be ltered and routed appropriately. This value often does not need to be changed from it’s default value as it is automatically reported in the PMT table.

6.10.7 Audio PID: [21-8190]
The audio PID (Packet Identier) is a decimal number that uniquely identies an audio transport stream in an MPEG-2 transport stream so that it can be ltered and routed appropriately. This value often does not need to be changed from it’s default value as it is automatically reported in the PMT table.
6.10.8 PCR PID: [21-8190]
The PCR (Program Clock Reference) PID (Packet Identier) is a decimal number that uniquely identies the time base for synchronization of individual frames or elds of the video stream and their associated audio. This value often does not need to be changed from it’s default value as it is automatically reported in the transport stream. Typically it always takes the same value as the video PID.
6.10.9 PMT PID: [21-8190]
The PMT (Program Map Table) PID (Packet Identier) is a decimal number that uniquely identies a PMT table in an MPEG­2 transport stream. The PMT contains a data structure specifying which PIDs carry the video, audio and data stream that collectively constitute the broadcast program. This value often does not need to be changed from it’s default value as it is automatically reported in the PAT table.

7.2.4 Add & Drop Mode:
This check box selects whether the ‘Demod & Mux Settings’ tab is enabled. The ‘Demod & Mux Settings’ are required if a demodulator is installed. After activation see “Demod & Mux Settings Tab” on page 10-1. After checking the box click Submit button to apply the change.
7.2.5 Dynamic PSI Monitoring:
Selects whether Dynamic PSI (Program Specic Information) monitoring is enabled. This will instruct the unit to monitor the incoming PSI tables for changes and reanalyze the stream when they occur. This feature is active in add/drop mode only.
7.3 Legacy STB Settings
7.3.1 Lock to V-Sync:
The default setting is ‘Lock to Internal Sync’; the check box is not selected. Issues with vertical sync quality will usually manifest as constant or occasional vertical rolling of the image. The quality of the baseband vertical sync signal can be impacted by a number of factors including source quality, cable length, connectors and the presence of distribution amps. Using the internally generated timing signals is usually the most reliable method of sync recovery but in some circumstances better results maybe achieved by using the external baseband sync signal if vertical rolling is experienced. In this case click the selection box. This setting is not directly related to legacy STBs.
7.3.2 QBA & AF Enable:
Selects whether QBA and AF are enabled. Necessary only for some legacy set top boxes. Default; the check box is not selected.
7.4 DVB® SI Settings
These settings are not always required to be used for typical operation. They provide additional features if required by system operator.
7.4.1 DVB® -SI/PSIP:
This setting is a drop down menu with preset options.
• None
• DVB-SI
This selection enables support for passing/updating the SDT (Service Description Table) and NIT (Network Information Table) tables through the multiplexer in a drop & insert application as well as creation of SDT/NIT tables in encoding mode. It may be necessary in some installations to enable these tables to be received by the end user when tuned to the DigiVu programs. In add/drop applications the SDT/NIT tables must be existing in the incoming QAM. If the tables do not exist, do not attempt to enable this feature.
• PSIP

7.5 No Video Slide Enable
This ‘No Video’ feature allows a slide to be shown to the viewer on an SD channel that loses video input to the encoder card. There is a pre-congured default slide, Figure 7-5, but a custom slide may also be uploaded to the system, see “7.5.4 Custom Slides”.
NOTE: This feature is only available for use with SD encoder cards DV1CE, DV2CE, DV1CEM & DV2CEM. This will not work with the current HD encoder card.
7.5.1 If Checked
On loss of video to an SD encoder, the DigiVu displays a built-in or custom slide graphic on the program output of encoders. One slide will display on all active encoders.
7.5.2 If Not Checked
7.5.3 Built-in Slide
The default built-in slide provided displays a message indicating that a video source is not detected and advises that the video source and cables should be checked. This feature is useful to avoid blank channels in the lineup when local video sources fail. It indicates that the DigiVu is functioning and RF output is present indicating that other customer premise equipment should be checked rst. In some situations this may help prevent unnecessary service calls for the DigiVu platform. Once this feature is enabled by ticking the box, a menu is activated which allows selection of either the default slide or a custom slide.

8.1 RF Settings
Settings affecting the QAM RF output of the DigiVu are congured on this page. QAM output conguration settings and operation is based on ITU-T Recommendation J.83 standards.
8.1.1 RF Frequency: [15000-975000] (kHz)
Enter the required QAM output channel center frequency here in kHz without any decimals or commas. This supports STD, IRC and HRC channel plans. The limits of tuning are 30 MHz to 960 Mhz.
NOTE: Uniform RF performance (as per published spec) is available between 30 MHz and 960 MHz. The areas close to lowest/highest tunable range fall in the roll-off of the operating range and RF parameters (for instance MER) are starting to degrade in these two border areas. Depending on desired application this might or might not be acceptable. It should be tested under such application to obtain relevant data about suitability.

8.1.3 QAM Modulation Type:
The type of QAM modulation is selected here and is dependant mostly on locale. In general, the following applies:
• QAM-B is dened in ITU-T standard J.83 Annex B for use in North America and other territories following same standard.
• QAM A/C is dened in ITU-T standard J.83 Annex A and J.83 Annex C for general use in Europe, Japan and other territories following same standard.
8.1.4 Symbol Rate: [2000-7000]
The values presented as preset options depend on the QAM modulation type selected. QAM-B has two predened values, but QAM-A/C allows a user dened setting along with some common predened values. All DigiVu models support symbol rates between 2000 and 7000 symbols per second.

9.2 DVIS Information
9.2.1 Product ID:
This is the hardware serial number.
9.2.2 Version:
The system rmware version installed in the DigiVu. This is the version to check if new rmware is required or recommended. (Ignore the version number on the top right corner of the GUI display. That number is indicating the version of the GUI, not of the DigiVu system.) The numbers displayed here directly relate to the rmware version that will be posted to the ATX Networks support site.
For help with rmware upgrades, see “Contact ATX Networks” on page 15-1 for contact phone numbers.
Information and procedures for obtaining rmware les and installing the rmware may be found at “Firmware Upgrade &
Recovery” on page 12-1
Availability of rmware for your DigiVu may be checked at the ATX Networks support sites listed here “Where to Obtain

9.3 DVIS Hardware Status
9.3.1 Start Fans Above: [0 to 75]
Temperature at which the fans begin operating. This may be set manually to any temperature between 0-75 °C though the default value of 10 °C is recommended.
9.3.2 Alarm Temperature: [0 to 75]
Temperature at which an alarm is initiated. This may be manually set to any temperature between 0-75 °C. This is the temperature at which an SNMP trap is sent to the SNMP manager, if installed and congured.
Figure 9-2: DVIS Information Section
Figure 9-3: DVIS Hardware Status
NOTE: Setting this temperature articially low is not recommended. When the DigiVu equipment internal temperature reaches this limit, internal power is switched to a lower power mode and the unit will remain in this mode to prevent damage to the hardware until the temperature drops below the set level. This is intended to avert a major hardware failure due to excess heat buildup.
9.3.3 Fan A Status:
Shows whether the fan is On, Off, or Out of Order (indicating fan failure).
9.3.4 Fan B Status:
Shows whether the fan is On, Off, or Out of Order (indicating fan failure).
9.3.5 Temperature:
Current internal temperature of the unit (°C).
9.4 SNMP Settings
All DigiVu support sending SNMP (Simple Network Management Protocol) traps to a remote SNMP manager. This lets TCP/IP-based network management clients use a TCP/IP-based internetwork to exchange information about the conguration and status of nodes. A MIB is required to be compiled into the remote manager in order for it to understand the SNMP traps.
9.4.1 SNMP MIB
The DigiVu MIB may be browsed with an SNMP Manager once it is compiled into the manager. The following values may be received by SNMP:
• “RPM measured on Fan 1”
• “RPM measured on Fan 2”
• “Channel 1 Video Status”
• “Channel 2 Video Status”
• “Channel 3 Video Status”

9.6.8 Import/Export Firmware Versions Must Match
Because different rmware versions might contain different features and therefore different elds for setting parameters, export and upload will only work reliably and correctly if the originating and receiving DigiVu are running the same rmware version. It is obvious that there will be problems if originating and receiving device don’t have same feature set and it will not be known by the device how to congure settings.
9.6.9 Settings Selection
The DigiVu platform provides several choices for the granularity of the amount of data to be saved when settings are exported. To start the settings export process, click the Export Settings button. When the export settings dialog is opened, see Figure 9-8, a number of choices are provided to allow just the required data to be exported. One may be tempted to just select ‘All Settings’ as this may intuitively seem the best choice but carefully consider the circumstances of the machine receiving the data. If it intended to use the data as a backup which will be restored to the same DigiVu in the same network, this is the best choice. If the receiving DigiVu is another machine in another location, the choice of data exported must be made with careful consideration. An explanation of the data that will be exported with each selection is outlined here:
1. All Settings
All settings of the entire DigiVu platform. Perfect for a backup database.
WARNING:—If a remote re-conguration of a DigiVu (the target DigiVu) is performed while connected through an IP network, the ‘All Settings’ check box has to be unchecked. Otherwise, the exported ‘Network Settings’ of the source DigiVu (the source of the exported le) will load into the target DigiVu and those settings will be incorrect unless the target and the source DigiVu are the same machine. Every remotely accessible device has unique ‘Network Settings’ which will be overwritten if we check this box. The result will be that internet access to the remote DigiVu is lost and someone has to visit it locally to reset the Network Settings appropriately for network access.

All settings from ‘Encoder Settings’ page get exported and later loaded in the other DigiVu.
3. MUX and RF Settings
All settings from ‘MUX and RF Output’ pages get exported and later loaded in the other DigiVu.
4. IP Output Settings
All settings from ‘IP Output’ page get exported and later loaded in the other DigiVu.
5. Maintenance Settings
All settings from ‘Maintenance’ page other than Network settings get exported and later loaded in the other DigiVu.
6. Network Settings
All settings from ‘Network Settings’ section on the Maintenance page get exported and later loaded in the other DigiVu.
7. Demod and MUX Settings
All settings from the ‘Demod and MUX Settings’ page get exported and later loaded in other DigiVu.
NOTE: Because the ‘Demod and MUX Settings’ page uses data from an incoming QAM in a specic QAM RF distribution network, exporting and loading these parameters only makes sense if the ‘receiving’ DigiVu operates in the exact same QAM RF network. Otherwise in a different QAM RF network this export settings le won’t work because the QAM channels, programs, frequencies, etc. could be different, therefore incorrect values will be loaded.
NOTE: In order to generate settings in the ‘Demod & MUX Settings’ page it is required to connect the DigiVu to the QAM RF network to collect data as required for the Demod & MUX page. Parameters in all other GUI pages are generated directly in DigiVu, but parameters in the Demod & MUX Settings page are a combination of real-life received/analyzed data and modication performed by the DigiVu. It is important to note that the Demod & MUX page data always and only can be created in the system in question and cannot be generated in a lab/ofce located elsewhere.

2. Click Export Settings button.
3. A window opens allowing the selection of the dataset to be exported from this DigiVu. After selection click Export.
4. A new window will open with a web-link to download the settings le.
5. Click this hyper-link.
6. Another new window opens with a prompt to act on the le, (it’s format depends on the browser used and it’s version) asking to open or save this le.
7. Save this le in a known location on the PC. You may accept the offered le name or change it in any way you want to personalize it to identify the DigiVu it is saved from. Without renaming, every DigiVu export le will be named identically.
8. This le can be used later to be uploaded into a DigiVu through the DVIS Update page, in same way as new rmware would be loaded. The execution of such uploaded le happens in same way as when rmware les get uploaded, and after that process is done the receiving DigiVu will have same parameter settings as originating DigiVu.
9.7 Network Settings
This section denes the setting for the Ethernet GUI port on the DigiVu 1RU Mini front panel and the DigiVu 3RU back panel. The conguration of the Gigabit Ethernet card
is detailed in “IP Output Tab” on page 11-1.
NOTE: Any change to network parameters triggers a reboot when applying the changes with the ‘Set Network’ button.
9.7.1 Static IP Address:
An IP (Internet Protocol) address is a numerical identication assigned to devices participating in a computer network utilizing the Internet Protocol for communication between nodes. When a computer is congured with a Static IP address it always uses the same IP address. When a computer is congured with Dynamic IP addressing it automatically procures an IP address from a DHCP server when required. If the installation requires a static IP address that value would be entered here. This value is greyed out when DHCP Client Mode is enabled. The greyed out address is not the address procured from the DHCP server. The DHCP assigned address shows up if the button ‘Network Info.’, see Figure 9-13. The address range that is supported as well as the default IP address settings are outlined in the following tables:
IP Address 192.168.0.23
Subnet Mask 255.255.255.0
Web Server Port 80
Gateway 192.168.0.1
DNS IP Address Not Dened
Figure 9-10: Network Settings Section
IP Address Range Supported
IP Class Start Address End Address
A 10.0.0.0 127.255.255.255
B 128.0.0.0 191.255.255.255
C 192.0.0.0 223.255.255.255
Factory Default IP Addresses
9.7.2 Web Server Port:
This is the TCP/IP port that is used to remotely access the DigiVu. The default value is port 80 which is the well known port for HTTP protocol web servers and is the default value used by a web browser if no port is specied. For additional security or to allow the product to work properly behind some rewall congurations, the port used for access may need to be changed. If the port is changed to 8000, for example, the product would then be accessed by a web browser with the following address notation: http://xxx.xxx.xxx.xxx:8000 where the actual public IP address replaces the x’s
9.7.3 Subnet Mask:
A subnet mask must be set to dene what part of the network address is applicable to the subnet that the DigiVu exists on. This should be set according to the overall network design. The default value of 255.255.255.0 will work ne with the default

private network address of 192.168.0.23
9.7.4 Default Gateway:
9.7.5 DNS IP Address:
NOTE: Cannot be ignored for remote access! This address must be entered, though it may be any IP address including an address that is not specically a DNS server. A Google DNS Address that may be used is 8.8.8.8
DNS (Domain Name System) servers translate human-readable domain names into machine-readable IP addresses and the reverse. For remote access a DNS IP address must be entered.
9.7.6 MAC Address:
9.7.7 Notify Server URL:
This feature is not yet implemented
CHAPTER 9: MAINTENANCE TAB
9.7.8 DHCP Client Mode Enabled:
NOTE: Once DHCP is enabled and an IP address is assigned you will need to externally determine what the IP address was set to in order to access the DigiVu again through the Ethernet port. Further, you may need to set your computer to the corresponding subnet if you are directly connected to the DigiVu on the network. Your Network Administrator may be able to help with this. For information on setting the IP address of the PC see “5.4 Connecting to the GUI” on page 5-2.
9.8 Platform Network Control Buttons
9.8.1 Change Username & Password
For security purposes, the DigiVu has a Username and Password which must be entered for access to the GUI. The username and passwords may be changed through the dialog that opens with this control. After changing the username and/or password, the DigiVu must be rebooted in order for the changes to become effective. After the reboot, the new username and password must be used. The username and password may not be set to null (No entry or blank).The DigiVu system provides for a single system user and password who is allowed to modify all settings. The dialogue that opens when you click Change User&Password button allows the user name and password to be modied. After changing the settings, click Send to apply the new settings. The DigiVu GUI will close and you will be requested to log in under the new credentials.
Figure 9-11: Platform Network Control Buttons
FYI: If the Username or Password have been changed and subsequently forgotten, there is a way to recover the DigiVu without loss of programmed conguration. A username/password reset le is available which can workaround this problem. Contact ATX Networks technical support at the numbers listed
under ”Contact ATX Networks” on page 15-1 for assistance.

This button opens an information window that summarizes Ethernet network information such as IP address (even DHCP assigned), packets received and transmitted, the link status, data collisions and the number of RX and TX bytes. This is for information only. An example is shown in Figure 9-13.
9.8.3 Set Network
NOTE: For every pressing of the ‘Set Network’ button, the platform will reboot.
If any parameter in the ‘Network Settings’ section has been changed, they need to be saved and applied to the DigiVu in order to take effect. This is done by clicking the Set Network button which applies the network conguration changes. A platform reboot will always take place.
Figure 9-13: Network Information Window
NOTE: If the network address has been changed, then the platform will reboot and you will need to open a new browser session with the new address entered in Internet Explorer. This is exactly the process described earlier in Chapter “5. The GUI” on page 5-1. For specic details see “5.6.4

10.2.2 Quick Guide to Tuning the Demodulator
Refer to Figure 10-2 for clarication of this process.
1. Open the ‘Demod & Mux Settings’ tab.
2. Depending on the QAM Demodulator type (Qam -B ATSC vs QAM A/C, ETSI), the symbol rate may need to be set rst. For QAM-B the setting is automatic, for QAM A/C obtain the symbol rate from the cable system operator.
3. Click Demodulator Settings button.
4. Set QAM type, QAM Mode and Channel Center Frequency. These values will be copied into ‘Demod Settings’ when tuning is nished.
5. Click the Tune button. The tuning process will take some time. If the QAM can be tuned, the indicators, which are initially red, will turn green. The tuner is also determining signal quality during this time.
6. When lights have turned green and ‘BER’ (Bit Error Rate) value is populated (allow some time for BER data collection), click the Apply & Close button.
7. Click the Analyze button. The analyze info window opens for about 1 minute then displays ‘Completed’.
8. The PID Display Tree is populated with the detected streams and their MPEG properties.

10.2.3 Quick Guide to Drop and Add a Program
Refer to Figure 10-3 for clarication of this procedure.
1. Left click the program to be dropped in the ‘PID Display Tree’ in order to highlight it
2. Right click that program and a drop down menu appears (Active, Drop).
3. Click Drop. A replacement program is populated in the Add & Drop Settings window area with same program number as the dropped program, The dropped program is greyed out.
4. In the ‘Add & Drop Settings’ section select the ‘AV Channel’ (the DigiVu encoder port that is physically connected to local baseband source) to be inserted; AV1 or AV2 etc. (Initially the drop downs for ‘AV Channel’ will show ‘None’).
5. Click Set Bit Rates. DigiVu will analyze the incoming stream and attempt to assign the highest bit rate to each added AV Channel that the available space will allow.
FYI: The bitrate computed in step 5 will be assigned to each program in ‘AV Channel Bit Rate’ column. Since the algorithm is assigning all available bitrate headroom, it might happen that these values are extremely high and need adjustment downward. To do so, click into the eld with assigned ‘Video Bit Rate’ and enter an appropriate bitrate number (this number depends on several factor). Do this for all available ‘AV Channels’.
6. The assigned bitrate for each encoder may be adjusted downward if necessary.
7. Select “Audio Bit Rate” for every available AV Channel. The recommended setting is 192 kbps.
8. Click Congure button. The settings are saved to the DigiVu conguration.
9. Click Start button. This starts the multiplexer add/drop process.

10.3 Demod & Mux Settings
The following is a description of the ‘Demod & Mux Settings‘ conguration page. The page is divided into 3 main sections as shown in Figure 10-4:
• Demodulator Settings
• Add & Drop Settings
• PID Display Tree
Each of these screen sections are described next.
10.4 Demodulator Settings
This area displays the parameters of the QAM demodulator. These values are adjustable in the ‘Tuner Diagnostic’ dialog that opens when you click the Demodulator Settings button. That will be discussed below. The four parameters that are displayed are:
Figure 10-4: Demod and Mux Settings Conguration Page
Figure 10-5: Demodulator Settings
10.4.1 QAM Modulation Type:
This is the type of QAM standard that the Demod will use and is determined mostly by locale and the Demod Card installed (two versions are available); generally QAM B for North America and QAM A/C for Europe (and appropriate territories following standards from North America/Europe/Japan).
10.4.2 QAM Mode:
Depending on the QAM Type selected above, the QAM mode is preset to a few possible values. For QAM-B available options are 64 QAM and 256 QAM. For QAM-A/C available options are 16QAM, 32QAM, 64QAM, 128QAM and 256QAM.
10.4.3 Channel Frequency: [54000 - 866000]
This is the center frequency of the EIA/RF/CCIR channel to be demodulated. The possible values are 47000 kHz to 897000 kHz. Do not enter any commas or other punctuation marks.
10.4.4 Symbol Rate: [2608 - 6956]
10.4.5 BER:
This is the measured Bit Error Rate (or Bit Error Ratio) on the tuned QAM channel. This value should be very low, preferably
0.0E-08, indicating a quality signal. If the BER is worse than 1.0E-06 an investigation into transmission problems on the cable system should be undertaken.
10.5 Demodulator Settings Buttons
10.5.1 Demodulator Settings
This control opens the Tuner Diagnostics window that permits changing the relevant conguration and verifying the successful tuning of the specied QAM. The screen
capture construction in “Quick Guide to Tuning the Demodulator” on page 10-2 outlines the process. The window contains
three indicators which are red by default when the window opens. Opening the Tuner Diagnostics window will always initially display the three indicators as red, even when the tuner is currently properly tuned and locked. This screen must be refreshed every time it is opened by clicking the Tune button. If the QAM demodulator cannot tune and lock on the carrier, the indicator lights remain red, however, upon successful tuning and locking of sync, all three of the lights should be green and in a few moments the BER (Bit Error rate) is measured and populated. The action of clicking the Tune button is not service affecting

unless the QAM parameters have been changed since the window was opened.
10.5.2 Tune - Control
After entering or selecting the values in the dialog, click the Tune control. This causes the tuner to attempt to nd the carrier detect frame sync and lock on the frequency. Successful tuning results in the three indicators lighting green and the tuner then attempts to evaluate the bit error rate of the channel. The BER is posted in a few moments if successful.
10.5.3 Apply and Close
When the lights are all green and the BER is posted, click Apply & Close to apply and save the settings and close the window. The 4 set parameters will be copied into the “Demodulator Setting” section.
10.6 Add & Drop Settings
This section displays the local encoder settings in the ‘Add & Drop’ mode only. This is where local encoder video and audio encoding bit rates and program numbers are set when the add/drop mode is activated. If the Add/Drop mode is not being used, encoder parameters are set on the ‘Encoder Settings’ page. In Add/Drop mode, some parameters can still be set in ‘Encoder Settings’ page, but the ones which are restricted are greyed out. Programs will automatically be added in this window when an incoming program is dropped in the ‘PID Display Tree’. Other local encoder channels may be added into an incoming QAM (if enough bitrate is available) from this window as required without dropping every program from incoming QAM. Conguring local programs will force the use of the automatic bit rate congurator, the ‘Set Bit Rates’ button, but the bit rate assigned to

an encoder could exceed the output capability of the used encoder card (for example for SD it’s 8000 kbps). If this happens, change the bit rate manually to a lower value. This can happen because the algorithm assigns all available bitrate in a QAM, and if the QAM is ‘empty’ the available bitrate is high.
10.6.1 Program
This is the MPEG program number assigned to the program. This may be changed to any number as required by your system. If a program is being dropped, the program number assigned to the inserted program is the number of the dropped program. The program number assigned here will show up in ‘Encoder Settings’ page as greyed out numbers (in appropriate port view).
10.6.2 AV Channel
10.6.3 Video Bit Rate
The bit rate assigned to the local encoder after clicking the Set Bit Rates button. This value depends on the installed encoder card. If the bit rate congurator automatically assigns a bit rate that exceeds max allowed bitrate, manually set it to less. A higher bit rate equates to higher quality video transmission but setting a high bit rate will not improve low quality video presented to the encoder input.
10.6.4 Audio Bit Rate
This is the bit rate of the audio program. Depending on the encoder card installed, default values will be available to be chosen as required by your system. Recommended setting is 192 kbps.
10.6.5 AV Channel Bit Rate
This is the aggregate bit rate for the overall program including the individual encoded video and the audio streams.
10.6.6 Total AV Bit Rate (kbps)
This is the aggregate total bit rate of all of the programs added in the ‘Add & Drop Settings’ section. The total includes the video and the audio encoder bit rates. This value may equal but must not exceed the value of ‘Total Available Bit Rate’ displayed below the ‘PID Display Tree’ section.
10.7 Add & Drop Settings Buttons
A description of the functionality of the control buttons of the ‘Add & Drop Settings’ feature.
10.7.1 Clear Add & Drop Button
If there are any programs entered into the program list, this button clears all entries. The added programs may also be removed one at a time by right clicking the programs and select Remove when prompted. For programs that are dropped from the ‘PID Tree’, they may be added once again only from the ‘PID Tree’ section.
10.7.2 Add Button
This enters new programs in the list that have no relationship with the incoming QAM; i.e. are not replacements for dropped

incoming programs, just newly added programs to the QAM. Programs are entered with default audio bit rates which may be changed. The video bit rate will be calculated so do not enter the desired video bit rate until after clicking the Set Bit Rate button.
10.7.3 Set Bit Rates Button
This control automatically calculates the video bit rate of each added program based on the bandwidth available. This is determined by measuring the transport stream null stufng, if any, and the bit rate made available by any dropped programs. It then subtracts the audio bit rates that were specied by the added programs plus some stream headroom, and divides the remainder by the number of added programs. The result is automatically entered as the ‘Video Bit Rate’. Each individual video bit rate may be changed at this point but do not allow the aggregate bit rate to exceed the ‘Total Available Bit Rate’ specied in the display under the ‘PID Display Tree’. This is not service affecting.
10.7.4 Congure Button
This control saves the specied settings for the added programs to the DigiVu multiplexer. This is not service affecting.
10.7.5 Start - Control
This reads the settings saved with the ‘Congure’ control and applies the settings to the multiplexer.
NOTE: Clicking ‘Start’ is a service affecting operation

10.8 PID Display Tree
The ‘PID Display Tree’ is an MPEG stream analyzer display of the incoming programs detected in the received QAM transport stream PAT and PMT tables. See Figure 10-9 for an example of the PID tree display. Only programs listed in the transport stream tables will be displayed. This display makes selecting and dropping the correct program easier. Clicking on the + signs opens the stream parameters for closer inspection of individual PIDs and detected bit rates. Bit rates are read over a short period of time and are a snap shot of the stream and are valid only at the time of analysis; if they subsequently change the display is not updated.

10.8.2 TS Version:
Each time the stream analyzer function is used, this number increments. It does not relate to anything about the stream itself.
10.8.3 TS ID:
This is the ID number assigned to the transport stream at it origin. This would be assigned to the stream multiplex before being modulated to the source QAM channel.

CHAPTER 10: DEMOD & MUX SETTINGS TAB
10.8.4 Bit Rate Margin
This is the margin or headroom detected in the incoming stream. This allows some small change in the aggregate bit rate of all of the TS programs without exceeding the QAM channel maximum bit rate.
10.8.5 Null Packets Bit Rate
The transport stream may not contain all MPEG stream data. If the analyzer detects null stufng, it displays the data rate of the nulls here.
10.8.6 Transport Stream Total Bitrate
10.8.7 Program Components
Each program listed in the stream PAT and PMT tables will be displayed along with their assigned MPEG program number. Each program is further broken down into it’s components:
10.8.8 PMT Table
The table that announces the PID assigned to each individual elementary stream; the Audio and Video streams. The PMT table is contained within it’s own data stream with a PID assigned
• PMT PID
The PID assigned to the PMT table. This cannot be changed.
• PMT Bit rate
The bit rate of the PMT table. Information only.
10.8.9 ES Type=13818-2 Video
The stream analyzer will determine the video stream type and display it here. In this example the stream is detected as 13818-2 Video. The number 13818-2 is the standard that denes MPEG-2 video. If your system carries different video, this will reect the video detected. ES means Elementary Stream. Each program stream is comprised of one or more elementary streams.
• ES PID
The PID assigned to the Video Elementary Stream.
• ES Bit Rate
The bit rate of the Video Elementary Stream in kbps. In the illustrations, the actual bit rate displayed is the total of the payload data rate specied by the standard plus header packets
10.8.10 ES Type=ATSC_AC_3 Audio
The stream analyzer will determine the audio stream type and display it here. In the example illustrated the stream is detected as AC-3 Audio. If your system carries different audio, such as MPEG-1, the analyzer will reect the audio stream type detected. ES means Elementary Stream. Each program is comprised of one or more elementary streams.
• ES PID
The PID assigned to the Audio Elementary Stream.
• ES Bit Rate
The bit rate of the Audio Elementary Stream in kbps. In the illustrations, the actual bit rate displayed is the total of the payload data rate specied by the standard plus header packets.

IP OUTPUT TAB
11. IP Output Tab
This chapter is about the conguration of the Gigabit Ethernet (GbE) card shown in Figure 11-1. The GbE option supports transmission by multicast or unicast of the multiplex created by the encoders. The DigiVu platform can simultaneously create a QAM and IP output with programming duplicated on both. In this case the IP output will be a single multiplex of the created programs, an MPTS. If the DigiVu is congured for IP output only, then SPTS multiplexes may be created for each program. In IP output only mode the user can select either SPTS or MPTS transmission, but not a mixture of both. See “11.13 Stream
Settings” on page 11-8 to activate the SPTS feature.
FYI: Activation of the ‘IP Output’ tab requires that an IP Card be installed. If there is one installed check in the “Encoder Settings Tab” on page 6-1 to see that the IP Card is detected. The ‘IP Output’ tab must also be activated on the ‘Mux’ tab. See “Mux Tab” on page 7-1.

11.3 Support for VLAN Tagging
The Ethernet card supports the automatic creation of two VLANs or Virtual Local Area Networks. This feature may be used to allow both routing the streaming of the output video and access to the GUI on two separate virtual networks as if there were two separately wired physical networks installed. In VLAN tagging, the broadcast domain is extended across the VLAN as if the devices in the group were all locally connected together. VLANs also extend the DHCP server requests across the same virtual network if DHCP is used to assign network addresses. In this way the GUI and streaming IP output may be assigned addresses independently from two separate pools or DHCP servers.
By using VLANs, the video and management access streams, while arriving together, are separated at the destination switch into two distinct VLAN groups, each routed to a specic physical port dened by the VLAN. In this way all streaming video will be routed to the video receiving device, like a CherryPicker and the management access will be routed to the management computer(s). In this way only trafc intended for a receiving device will receive it. Since broadcast domains are extended over VLANs, all of the features of a broadcast domain are extended across the VLAN as well. See “VLANS Settings” on page 11-6 for specic details on this.
CHAPTER 11: IP OUTPUT TAB
11.4 Gigabit Ethernet Card Fundamentals
11.4.1 SFP Support
The card supports two SFP modules (Small Form-Factor Pluggable) allowing single mode and multi-mode optical modules to interface to the GbE ports providing long range and secure interfaces to switches, routers and remote sites. Many types and manufacturers of SFP have been tested with good results but because of the vast offering of various SFP modules, it is not possible to test all of them. It remains up to the customer to verify that his SFP will work as expected.
11.4.2 Integrated Switch
The Gigabit Ethernet card integrates a GbE switch on board allowing the card to transmit simultaneously from up to 4 Ethernet ports; 2 copper RJ45 type ports and 2 SFP ports. SFP Modules must be purchased separately and so far, SFP modules that are incompatible have not been identied.
11.4.3 Protocol Support
The card supports DHCP, ICMP and ARP protocols as well as VLAN tagging. Before unicast transmission is started the card will rst attempt to nd the destination MAC address of the receiving side (when using unicast transmission) using ARP protocol. When the MAC address is found, transmission begins.
11.5 Quick Guide to the Gigabit Ethernet Card
If more information is required, see the detailed conguration descriptions following this quick guide.
1. Insert the Gigabit Ethernet card into slot 2 (DigiVu Mini) or 5 (DigiVu and DigiVu CD).
2. Open the ‘Mux’ tab and change the ‘Output Selection’ to either ‘Ethernet Only’ or to ‘RF & Ethernet’.
3. Verify insertion and detection of the card on the ‘Encoder Settings’ tab – Card is detected as ‘ETH1000’.
4. Open the IP Output tab and congure the Gigabit Ethernet Card with the following parameters as required:
• Source IP Settings:
◦ IP Address – The IP address of the Ethernet Card physical interface. Only one required for all 4 ports.
◦ Subnet Mask – Identies the subnet of the IP address specied above.
◦ Source Port – Source port that will be specied when sending the TS data.
◦ Enable DHCP Client – When selected, the Gigabit Ethernet Card will obtain a dynamic IP address
(Source address) from a DHCP server and use this address for all Ethernet transmissions. A source port is not obtained from a DHCP server.
• Destination IP Settings:
◦ IP Address – The IP address that the Gigabit Ethernet Card transmits to.
◦ Destination Port – The virtual destination port that is used for the TS data transmission.
DigiVu® Series Multichannel MPEG-2/H.264 Encoder/Multiplexer with QAM &/or IP Output - Installation & Operation Manual 11-3
Page 74
CHAPTER 11: IP OUTPUT TAB
◦ Enable Multicast – When selected, the Gigabit Ethernet Card will not attempt to nd the destination IP
address with ARP before transmission begins.
• Protocol Settings: ◦ Encapsulation – The encapsulation type that is used for the TS data transmission.
◦ Number of TS Packets Per Frame – how many TS packets will be used in each Ethernet frame.
◦ Enable Pro-MPEG FEC – enables the Pro MPEG forward error correction.
◦ L Value, D Value – FEC Parameters.
◦ Col Port – port number to use for transmission of FEC column data.
◦ Row Port – port number to use for transmission of FEC row data.
◦ Use Col FEC Only – use only Column FEC for the FEC.
◦ Interleaving Mode – which interleaving mode to use for the FEC.

11.6 IP Output Conguration
11.6.1 SFP 1 Info.
This is where the GUI will report if there is an SFP installed in SFP Slot 1. If there is no SFP it will say “Not Connected”.
11.6.2 SFP 2 Info.
This is where the GUI will report if there is an SFP installed in SFP Slot 2. If there is no SFP it will say “Not Connected”.
11.6.3 MAC Address:
11.6.4 Firmware Version:
The rmware version installed on the Gigabit Ethernet card - for information only.
11.7 Source IP Settings
This section sets the physical IP address conguration for the SFP and Electrical Ethernet ports. All ports are replicated in an integrated switch, so there is only one IP address assigned to all of the physical ports collectively.
11.7.1 IP Address:
A static IP address may be specied here that is assigned to the Ethernet ports, collectively. Only one address may be assigned and this will be the source address that is reported in the resulting unicast or multicast streams.
Figure 11-4: IP Output Conguration
Figure 11-5: Source IP Settings Section
11.7.2 Subnet Mask:
If a static IP address is assigned, enter the subnet mask for the entered network address.
11.7.3 Source Port: [1-65535]
This is the source port number that may be assigned to the Ethernet ports, collectively. Only one port may be assigned and this will be the Source Port that is reported in the resulting unicast or multicast streams.
11.7.4 Enable DHCP Client:
The Ethernet card supports DHCP Client Mode on the Gigabit ports separately from the unit’s management port. This option enables the DHCP client on the Gigabit Card Ethernet ports only. Only a single address will be requested from the DHCP server. The source port will still need to be assigned even if DHCP client is enabled since DHCP will not assign a port number. When DHCP client is enabled, the IP address that is reported in the greyed out IP address and subnet settings above do not reect the actual IP address obtained. If that information is required, the DHCP server should be consulted, looking for the address that was assigned to the MAC address shown above.

Page 75
11.8 Destination IP Settings
This section sets the IP address that is assigned to the outgoing IP stream when working in MPTS mode. There will be only one multiplex created and only one address may be assigned. This address will be used across all of the output Ethernet ports as the four ports are on an integrated switch.
11. 8.1 IP Address:
This is the IP address that is assigned to the output unicast or multicast MPTS stream and will be reported in the resulting MPTS stream as the Destination IP Address.
11. 8 . 2 Destination Port: [1-65535]
This is the port number that is assigned to the output unicast or multicast MPTS stream and will be reported in the resulting MPTS stream as the Destination Port Number.
11.8.3 Enable Multicast:
This check box enables the use of multicast as an output. The Ethernet card does not use the actual assigned destination IP address range to determine if unicast or multicast transmission is desired. In other words, merely assigning a multicast address in the range 224.0.0.0 through 239.255.255.255 will not cause the output to be multicast.
• If this check box is unticked ARP protocol will be used to nd and establish a unicast connection to the computer or receiving device with the destination IP address. The stream will be unicast to the destination address specied. If the address of the destination specied is not found, the transmission will default to multicast.
• If this box is ticked The Ethernet interface will not need to nd the destination IP address before beginning transmission. It will assume that there are multiple receivers of the stream. The stream will be multicast to the address specied.
CHAPTER 11: IP OUTPUT TAB
Figure 11-6: Destination IP Settings
11.9 Protocol Settings
In this section, some conguration settings for the IP protocol may be changed.
11. 9.1 Encapsulation:
Denes the type of IP encapsulation to be used for IP transmission.
• UDP
User Datagram Protocol is a connectionless protocol (as opposed to TCP) and is commonly used to send audio and video over Ethernet. There is no ordering of the data enforced and data arriving late is ignored.
• RTP
Some routers support RTP (Real-time Data Protocol) and will pass data sent under this protocol with priority.
11. 9. 2 Number of TS Packets per Frame:
Here the number of MPEG packets that are encapsulated into each IP packet may be dened. The default value is seven, which is also the maximum number. Encapsulating more MPEG packets in each IP packet reduces overhead but there is more MPEG data loss with each lost IP packet. Assigning less MPEG packets per IP packet increases overhead but results in a possibly more robust stream. Seven is most commonly used.
11. 9. 3 Enable Pro-MPEG FEC:
The DigiVu supports transmission with Pro-MPEG FEC protocol dened by Pro-MPEG COP#3. For more information on conguring Pro-MPEG FEC see the Pro-MPEG FEC documentation at http://www.Pro-MPEG.org/
11. 9. 4 L value: [1-20]

11.10 VLANS Settings
The GbE output card supports automatic creation of 2 VLANs when this feature is activated. See “11.3 Support for VLAN Tagging” on page 11-3 for further information about the VLAN Tagging option. Figure 11-9 shows the implementation of VLANs to
assist in understanding and conguring the feature.
11.10.1 Active VLAN
This activates the use of VLANs for transport stream transmission and accessing the GUI over the Gigabit Ethernet card ports.
11.10. 2 Video VLAN VID
This is the Video VLAN ID

This is the GUI VLAN ID
11.11 GbE Port Numbering
Physical ports on the Gigabit Ethernet card each have a number assigned for purposes of conguring VLANs as shown in
Figure 11-9 and described here:
1. Trunk Ports are both labeled #1 on the front panel.
Trunk ports will receive/transmit only tagged Ethernet packets which will be routed to their destination according to their assigned VID. There is one each electrical and SFP (Small Form-Factor Pluggable) port which are identical functionally and interchangeable depending on the type of interface required.
2. Terminal Ports are both labeled #2 on the front panel.
Terminal ports are connected to a device (such as the management port) that does not support VLAN tagging but needs to be routed on a management VLAN. There is one each electrical and SFP port but the RJ45 port is typically used in this case.
CHAPTER 11: IP OUTPUT TAB
Figure 11-10: GbE Card Port Numbering
11.12 Two VLANs Automatically Created
1. Video LAN
The GbE video multiplex exists on this virtual LAN (it is connected to the switch through an internal port and the card connector). This means that the MUX output is connected to an internal switch in the GigE Card. MUX output then ows to both physical trunk ports; the ports labeled #1. These ports reside on the internal GbE switch so either may be used as the trunk output.
2. Management LAN
Both physical Ports #2 of the GbE card are congured on this Virtual LAN. Either of these ports connect to the Management Ethernet port through a straight wired Cat5e cable however typically only the RJ45 electrical port is used. These ports are mutually exclusive so only one or the other may be used.
11.12 .1 Quick Guide to VLAN Setup
a) Set up a remote external switch with VLAN support and
VLANs enabled for the GUI and streaming video.
b) On the DigiVu ‘IP Output’ tab select the Active VLAN check
box.
c) Set the VLAN VID for Mng (GUI) and Video VLAN VID to the
same VIDs used on the external switch.
d) Click Submit.
e) Connect the management IP port (from DigiVu Mini front
panel or the DiguVu 3RU back panel) to RJ45 GbE Port 2 on the GbE card using a short straight through Cat5e cable.
f) Connect one of the trunk ports labeled #1 (depends whether
you use copper or SFP) to a Trunk port on the external switch.
g) Connect a Management PC to the ‘Mng‘ management port at
the remote external switch and login to the GUI making sure both the PC and DigiVu reside on the same subnet.

CHAPTER 11: IP OUTPUT TAB
h) Connect another PC or the receiving device to the dened video port at the external switch and set it
up to capture the video over IP as was congured at the ‘IP Output’ tab.
11.13 Stream Settings
11.13.1 Single Program TS:
This feature allows the creation of Single Program Transport Streams (SPTS) from the IP output rather than all the programs being distributed in a single MPTS multiplex with a single IP address. This is available to be selected only when the Ethernet output alone is active. This setting is on the Mux tab. See “Output Selection:” on page 7-2 to select “Ethernet Only”. The conguration of the addresses, dening the address as multicast and enabling FEC is done in a table available on this IP Output tab. Only encoders that have been activated on the Encoder Settings tab will be available to congure. For information on that see
“Encoder Settings Tab” on page 6-1.
Figure 11-12: Stream Settings Section
Figure 11-13: Enable and Congure SPTS Feature
11.13. 2 Enable Constant BR Out:
Congures the multiplexer to output a constant bit stream at a dened data rate without regard to the actual payload data rate. This may be dened if a STB or other receiving device requires a bit stream at a dened rate. If the payload is less than the number dened here, null packets will be used to stuff the IP data stream to the dened output rate.
NOTE: This only works in MPTS mode.
11.13. 3 Constant BR: [1000-60000]
This is the CBR bit rate of the transport stream on the Ethernet network if a constant rate is desirable. Dening a bit rate higher than the payload will result in null stufng of the transport stream to the bit rate specied here.

FIRMWARE UPGRADE & RECOVERY
12. Firmware Upgrade & Recovery
In this chapter we explain the rmware upgrade process and where to get rmware les. We also discuss the procedure for recovering to a previous rmware version or resetting the username & password if it is ever necessary.
FYI: In this guide, reference to DigiVu infers DigiVu 3RU, DigiVu CD 3RU and DigiVu Mini 1RU
unless the model is specically stated. Reference to DVIS is synonymous with DigiVu as these products run on the same rmware.
New system rmware for the DigiVu platforms is provided in an archive le format of .tgz in a zip container and will be made available on the ATX Networks support site for each model of the DigiVu family, see “Where to Obtain Firmware Files” on page
12-3 to obtain the rmware. The DigiVu family uses a common rmware and it technically does not matter which support site
the rmware is obtained from. It is not necessary to un-compress the tgz package as the DigiVu has built-in facilities to accept the le in tgz format. The tgz le is provided from ATX Networks support site in a zip format, so it will be necessary to un-zip the le downloaded rst. The name of the zip le and the tgz le inside will be the same except for the extension and both will be named with the rmware version number. If you require a program to unzip the le, an open source le archiver may be
obtained for free at the http://www.7-zip.org/download.html site.

12.2 Types of Firmware Files
A brief description of the les that may be found on the support web sites.
12.2.1 System Upgrade/Recovery File
This is a le that is used to bring the DigiVu up to the latest rmware revision and is referred to as a rmware upgrade. This le may be used even if the equipment has a very old version of rmware installed as it completely replaces all les on the DigiVu platform and works with any previously installed version. This le can also be used to reinstall the latest rmware revision on an already upgraded device if there is suspicion that the rmware might not be working as expected and this application of the same le would be referred to as a system recovery. This is the most commonly installed le type and is installed in the same manner regardless of the end requirement. The following attributes apply to this le type:
• Can be used to upgrade any rmware version or when existing version is unknown.
• Fully replaces existing rmware.
• Suitable only when unit is physically available (cannot be applied remotely).
• Used to recover network parameters, login credentials or after mis-conguration.
• IP parameters and login passwords are reset to factory default.
• Requires full re-conguration of all channel parameters.
12.2.2 Remote Upgrade
This le type may be applied to the equipment even if it is remotely located. This rmware may be installed over a limited range of previous rmware so check the support site for qualifying existing versions.
• Usable for minor rmware changes. Check the support site for qualifying existing versions.
• Suitable when the unit is remotely located.
• IP parameters and login credentials are not changed.

CHAPTER 12: FIRMWARE UPGRADE & RECOVERY
• Channel parameters are not changed.
12.2.3 Username and Password Reset File
12.3 Identifying Current Firmware Version
The currently installed rmware version is displayed in the DigiVu GUI under the ‘Maintenance’ tab, as shown in Figure 12-1.
12.4 Exporting a Conguration
The DigiVu has the ability to export the programmed conguration as a le, which could be kept as a backup or used for mass deployment of a common conguration. It is suggested to export the conguration prior to upgrading rmware but the exported settings may not be used to restore after a rmware upgrade since system settings may be incompatible between rmware versions. The settings le may only be restored to a DigiVu with the same version rmware as the unit from which it originates. Making this backup is not service affecting and it is recommended that the settings be exported and saved whenever the DigiVu system conguration changes. The settings le is exported from the ‘Maintenance’ tab. Figure 12-2 illustrates what to do.
Figure 12-1: Identify the Current Firmware Version
Figure 12-2: Export Your Conguration
NOTE: If a rmware upgrade is undertaken, it will not be possible to use an exported conguration made as a backup since features introduced in the newer rmware will render the backup le from a previous rmware version incompatible. A backup taken will only be of use on a DigiVu with a rmware version the same as the version from which it is taken, ie. if the rmware is ever reverted back to the original version. Only use exported conguration les on a DigiVu of identical
rmware version.

12.5 Where to Obtain Firmware Files
Firmware upgrade les are released by ATX Networks periodically to add features or to address potential issues with released rmware operation. The rmware les, when released, will always be obtained from ATX Networks Technical Support.
If further information is required during any phase of the rmware upgrade, or you have concerns or questions about the rmware or it’s applicability to your DigiVu, contact ATX Networks Digital Video Support.
12.6 Firmware Upgrade Process
The following rmware upgrade process is the general format that will be followed. Each rmware upgrade may have specic criteria that will need to be adhered to and those criteria will be posted with the upgrade.
FYI: This manual does not contain specic up to date information for each release. Please read the instructions posted with each rmware release on the support web site.
NOTE: With the exception of applying the remote upgrade le and password reset le, applying system upgrade les will cause the loss of programmed settings. Record the conguration so it may be re-programmed before applying a system upgrade/recovery le.
12.6.1 Save Firmware File to Management Computer
Save the le obtained in a convenient location on the Management Computer. The upgrade le is named with the same name as the version of the upgrade although it may be contained in a zip wrapper. Extract the rmware le within the zip archive and save it in a convenient location on the Management Computer. This recovery le is in .tgz format and is itself an archive format. It should not be modied in any way or extracted further, though it may be renamed.
12.6.2 Direct Connect Management Computer to DigiVu
If connecting to your DigiVu directly through a cable, set the computer that you will use for the upgrade to the same subnet as the DigiVu in order to access the GUI. For example, if the network address for the DigiVu is set to the factory default setting of
192.168.0.23 set the Management Computer to an address between 192.168.0.24 and 192.168.0.255
If you do not know how to set the Management Computer to the same subnet as the DigiVu, see “Connecting to the GUI” on
page 5-2 for a tutorial on setting the IP address.
For connecting to your remote DigiVu through the Internet use the usual procedure for your situation. This setting cannot be specied here.

12.7 System Recovery Process
NOTE: Do not depress the ‘RESET’ button unless you have the appropriate rmware le available. This will cause your DigiVu to wait indenitely until the rmware is uploaded. There is no cancel button for recovery mode and once recovery mode has begun, the appropriate rmware le has to be uploaded to complete the recovery process.
12.7.1 Introduction
NOTE: All programmed settings will be lost. Record the conguration so it may be re-programmed before applying the system recovery le.
System recovery is intended to restore the DigiVu system in case it is suspected that internal les have become corrupted and that the GUI has become unresponsive. The Recovery Mode/Status is reached by pressing and holding, for several seconds, the ‘Reset Button’ until the fans stop running. The button is located on the front panel of the DigiVu Mini or the back panel of the DigiVu and DigiVu CD beside the Management IP port and is covered from the factory by a small adhesive dot to prevent inadvertent use. One fan will start running again while the other will remain idle. In recovery mode, the IP address setting of the Management IP port always reverts to 192.168.0.23 regardless of previously congured IP settings before recovery. Now the appropriate rmware le has to be uploaded, typically the latest rmware version upgrade le.
CHAPTER 12: FIRMWARE UPGRADE & RECOVERY
NOTE: By default the DigiVu IP address will be reset to 192.168.0.23 so it will be necessary to congure a computer on the same subnet to allow uploading the le, using an address between
192.168.0.24 and 192.168.0.255.
12.7.2 Obtain and Save Firmware Upgrade
Obtain the appropriate recovery rmware le and save it in a known location on the Management Computer. This le is in .zip format and its name contains the version code for this upgrade.
Extract the rmware le within the zip archive and save it in a known location on the Management Computer. This le is in .tgz format and is itself an archive format. It should not be modied in any way or extracted further.
12.7.3 Set Management PC Subnet
You will need to connect to your DigiVu directly through a cable, so set the computer that you will use for the upgrade to the same subnet as the DigiVu in order to access the GUI. The network address for the DigiVu unit will be reset to the factory default setting of 192.168.0.23 so congure the computer to an address between 192.168.0.24 and 192.168.0.255.
If you do not know how to set the Management Computer to the same subnet as the DigiVu, see “Connecting to the GUI” on
page 5-2 for a tutorial on setting the IP address.
12.7.4 Reset the DigiVu
NOTE: Do not depress the ‘RESET’ button unless you have the appropriate rmware le available. This will cause your DigiVu to wait indenitely until the rmware is uploaded. There is no cancel button for recovery mode and once recovery mode has begun, the appropriate rmware le has to be uploaded to complete the recovery process.
Using a pen or similar small pointed object, press and hold the ‘RESET’ button on the front panel of the DigiVu Mini or the back panel of the DigiVu or DigiVu CD for several seconds to place the unit in RESET/RECOVERY mode. You can recognise the condition when both fans stop operating, then after a few seconds they restart (this assumes that the fans were running). Wait about 1 minute more for the DigiVu to restart.
®
NOTE: In Recovery Mode, the DigiVu Management IP port reverts to 192.168.0.23.

12.9 Username & Password Reset Process
NOTE: Do not depress the ‘RESET’ button unless you have the appropriate rmware le available. This will cause your DigiVu to wait indenitely until the rmware is uploaded. There is no cancel button for RESET mode and once begun, the appropriate rmware le has to be uploaded to complete the process.
NOTE: The password reset le may be obtained from ATX Networks technical support group,
see “Contact ATX Networks” on page 15-1 for phone numbers and email address.
12 .9.1 Introduction
The Username/Password reset process is intended to restore the DigiVu factory username and passwords in case it is has been changed then lost or forgotten. After this process, the login credentials will be returned to factory settings but all other settings will be unchanged. The password recovery mode is reached by pressing and holding, the ‘RESET’ button for several seconds, until the fans stop running. The button is located on the front panel of the DigiVu Mini or the back panel of the DigiVu and DigiVu CD beside the Management IP port and is covered from the factory by a small adhesive dot to prevent inadvertent use. One fan will start running again while the other will remain idle. In reset mode, the IP address setting of the Management IP port always reverts to 192.168.0.23 regardless of previously congured IP settings before reset, then using the factory default IP address, the appropriate rmware le is uploaded.
NOTE: By default the DigiVu IP address will be reset to 192.168.0.23 so it will be necessary to congure a computer on the same subnet to allow uploading the le, using an address between
192.168.0.24 and 192.168.0.255.
12.9.2 Obtain and Save Password Reset File
Obtain the appropriate recovery rmware le from ATX Networks and save it in a known location on the Management Computer. This le is in .zip format and the version you are given will depend on the rmware version installed on your equipment.
Extract the rmware le within the zip archive and save it in a known location. This le is in .tgz format and is itself an archive format. It should not be modied in any way or extracted further.
12.9.3 Set Management PC Subnet
During this process, the network address for the DigiVu unit will be reset to the factory default setting of 192.168.0.23 so you will need to connect to your DigiVu directly through a crossover Ethernet cable. Set the computer that you will use for the recovery to the same subnet as the DigiVu in order to access the GUI, conguring the computer to an address between
192.168.0.24 and 192.168.0.255. If you do not know how to change the Management Computer subnet, see “Connecting to
the GUI” on page 12-5 for a tutorial.
