SYSTEM DESCRIPTION
2. System Description
DigiVu series products are cost effective and space efcient encoding, multiplexing and transmission platforms ideal for digital
simulcast applications, digital delivery of PEG, hub site specic programming, local channel insertion or headend encoding.
Several SD/HD baseband programs can be directly encoded/multiplexed and output in QAM or IP format, eliminating the need
for stacking and/or combining several units for multiple program encoding. Models exist with two and six card slots, accepting
various combinations of available cards. HTTP based GUI allows easy set-up and control without the need for proprietary
software installation Remote access and SNMP monitoring are available via integrated RJ45 Ethernet interface.
In this chapter we introduce the key features and describe the attributes that make the DigiVu Device a powerful addition to
any digital cable TV network.

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 specically 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 specic 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. Specic 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.
2-2 DigiVu® Series Multichannel MPEG-2/H.264 Encoder/Multiplexer with QAM &/or IP Output - Installation & Operation Manual
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 congured for SD or HD and can encode MPEG-2 or H.264 proles. 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 efciency. 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 congured 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 notication of the triggering of alarms either across a private network or the internet if available. Upon
triggering of a predened alarm, a trap is automatically sent by the DigiVu equipment to a listening SNMP management
console.
2.4.6 Flexible Transport Stream Re-Multiplexing
Flexibility is provided in conguring the re-multiplexed transport stream in an add/drop application. The inserted program may
be assigned any valid PID or MPEG program number and the encoder may be set to any of a wide range of valid CBR video
and audio encoding rates. A built in MPEG-2 stream analyzer (demodulator card required for this feature) for incoming MPEG
programs assists in making the correct selections for replacing programs easy and intuitive. MPEG tables PAT and PMT along
with all PID values are automatically generated to ensure that downstream STB can reliably tune the inserted multiplex and
minimum craft experience is required to implement a system. Dynamic PID monitoring avoids outages due to program table
updates.
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 Conguration Export
The DigiVu platforms allow the operator to export the programmed conguration 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 conguration thus

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 congured settings.
2.4.9 IPv4 Network Address Support
All DigiVu platforms support IPv4 IP addressing and maybe congured 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 congured 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 conguration of the DigiVu system is through a built-in web server which presents the conguration pages
in an intuitive tabbed format interface. Access to the GUI may be congured 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 sacriced
or for QAM channels that are designed for this program insertion feature. Encrypted programs will be replaced with an ‘in the
clear’ program.
See “Insertion into Under-utilized QAM (Add/Drop)” on page 3-4
3.2.4 IP Video Content Insertion
This application uses the DigiVu encoding capability with IP output to locally insert programming into an IPTV property or
remote hub for distribution or Headend encoding application.
See “IP Video Content Insertion” on page 3-5
3.2.5 Video Back Haul Schemes
These applications uses the DigiVu encoding capability with IP output, QAM output to haul a special remote origination

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.

CHAPTER 3: FIELD APPLICATIONS
3.4.3 Insertion Into Locally Deleted QAM
The DigiVu CD product can be used to insert local programming into an EIA channel where the cable system carries a
channel but providing customers with the programming on that channel is discretionary. In this scenario, a system EIA channel
is deleted using an optional channel deletion lter with very good adjacent channel performance and deep rejection of the
intended deletion channel. This lter is available from ATX Networks and is an integral part of the design of the DigiVu CD.
In this case, the DigiVu CD will create a totally new QAM channel and insert it into the blank spectrum following the output of
the lter.
Figure 3-3: DigiVu® CD - Insertion into Locally Deleted QAM
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 specic 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
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 benet 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 dened 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
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
Bare, covered or insulated grounding conductors are acceptable. A covered or insulated grounding conductor shall have a
continuous outer nish that is either green, or green with one or more yellow stripes.
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 airow 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 conguration
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 specied (50°C).
2. Reduced Air Flow:
Installation should allow at least 2” spacing around the equipment to ensure that airow 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
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 specication in an ambient room temperature of 0°C to +50°C (+32°F to +122°F).
Sufcient airow 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 airow 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 sufcient 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 specications 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
The input power requirement is constant over the range of input voltages. At higher input voltages, the current consumption is
lower than it is at lower voltages where the input current is higher.
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 congure 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.
DigiVu® Series Multichannel MPEG-2/H.264 Encoder/Multiplexer with QAM &/or IP Output - Installation & Operation Manual 4-3

230 VAC All AC IN Slow Blow 1.5 5 x 20 mm glass tube
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 conguration. An incompatible conguration, if it was installed or
congured 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, “Simplied 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
specication 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 specic 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
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.
CHAPTER 4: INSTALLATION
4.10 Ethernet Network
4.10.1 Ethernet Port
A front panel Ethernet network port is provided on the DigiVu Mini 1RU version. The DigiVu 3RU versions both have the
Ethernet port on the back panel. This port is to allow local and remote access to the equipment over the internet or a private
intranet.
Information about use of the Ethernet port may be found at:
Setting port IP addresses “Network Settings” on page 9-6
“Connecting to the Management Computer” on page 5-4
“Connecting to a Local Cable Modem” on page 5-5
The Ethernet port is DTE, similar to a PC Ethernet port and will require a crossover cable to connect to a PC. Connection to a
router or switch may be made with a standard straight through cable. Port speed is 10/100 Base-T and will auto negotiate the
connection based on the fastest common speed of the DigiVu and connected equipment.
4.10.2 Ethernet Cable Type
