1.2 Product Overview

Functional Description

The Wegener Unity 4600 Professional Media Receiver is a fully DVB-compliant satellite video IRD. The U4600 receives an L-band RF carrier from an external LNB, demodulates the carrier, extracts the MPEG transport stream, and provides the decompressed program or programs to DVB-ASI, composite video, and/or stereo audio outputs.

Features include:

• Control by local user or remote COMPEL system

• Download of software application upgrades via satellite

• Supports COMPEL/CA Conditional Access at transport level or by program

• Supports receiver card options using either DVB-QPSK or Advanced Turbo-Modulations (Turbo-QPSK, T-8PSK, or T-16QAM)

• DVB-ASI transport stream output with network-controlled program mapping

• Supports ISO 13818-1 transport rates from 2.5 to 55 Mbps (with local decompression) or up to 86.25 Mbps (to program-mapped ASI transport only)

• Local decompression of MPEG-2 video and MPEG-2 (L1 and L2) and/or Dolby AC3 audio

• Auto-recognition and support of 525-line NTSC or 625-line PAL

• Audio-only mode option for radio networks

• Alarm relay

Physical Description

• Cueing relays and DTMF cue tone outputs standard

• Optional SCTE 35 DPI message filter for network control of local ad avails

• Optional front-panel audio and video monitors

• Web browser control (to be released August 2005)

The U4600 is housed in a standard, 1 RU, rack-mountable chassis. Its front panel provides a user interface with six push buttons and an LCD window that displays two lines of text. Remote monitoring is also available through both the audio and video ports.

The rear panel holds connectors for input and output signals, LNB power supply, serial and Ethernet monitoring and control, alarm and user relays, and AC input power. The unit also includes two Unity expansion module slots.

CHAPTER 2 INSTALLATION

This chapter provides instructions on unpacking, mounting, and connecting your U4600 as well as connector information including detailed pinouts.

2.1 Unpacking and Inspection

Carefully unpack the unit and its ac power cord and inspect for obvious signs of physical damage that might have occurred during shipment. Any damage claims must be reported to the carrier immediately. Be sure to check the package contents carefully for important documents and materials.

NOTE: Please save the packing materials and original shipping containers

in case you must later return the unit for repair. Packing these units in other containers in such a way that they are damaged will void your warranty.

2.2 Location and Mounting

The U4600 may be mounted in a standard 19-inch equipment rack or set up for desktop operation. In either location, maintain a clean, dry environment for the U4600.

UNITY 4600 USER’S MANUAL

FCCMandated Suppression of Radio Frequency Emissions

If the Ethernet port has a cable connected to it, that cable must be properly shielded and grounded to minimize RF emissions that could interfere with nearby equipment.

WARNING

This is a Class A product. In a domestic environment this product may cause radio interference for which the user may need to take mitigating action.

DANGER

To avoid damage to the U4600 unit and other equipment, or personal injury, the following items should be strictly observed.

Elevated Ambient Operating Temperatures in Rack-Mounted Units

When equipment is installed in a closed or multi-unit rack assembly, the ambient operating temperature of the rack environment may be greater than the room’s ambient temperature. Therefore, consideration should be given to the ambient air temperature within the rack (not just inside the room) when deciding if the maximum recommended ambient operating temperature (T

Reduced Air Flow

Equipment should be installed such that the airflow required for safe operation of the equipment is not compromised. The U4600 may be arranged in a rack without empty spaces between units if heat buildup is prevented by ensuring that its side vents remain unblocked and that there is adequate clearance around the vent holes.

) is met or exceeded.

MRA

UNITY 4600 USER’S MANUAL

Mechanical Loading

Rack-mounted equipment should be installed in such a way that a hazardous condition is not produced by uneven loading. The U4600 unit is not very heavy, but total rack loading must be considered. Also, do not rest any unsupported equipment on a rack-mounted U4600 unit.

Circuit Overloading

Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of circuits could have on overcurrent protection and supply wiring. Ensure that the total rack or breaker power consumption does not exceed the limits of the AC branch circuit. Appropriate consideration of equipment ratings should be used when addressing this concern.

Reliable Earthing

Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (use of power strips, chassis ground lugs, etc.).

Rack Mounting the U4600 is sized as a single RU and will fit an EIA-standard, 19-inch-wide equipment

rack.

Desktop Installation

a. First install angle brackets or cross-supports capable of supporting both the unit

and its connecting cables. Screw or bolt the supports securely to the equipment rack.

b. Place the U4600 on its supports and use four anchor screws or bolts and nuts to

secure the U4600 front brackets to the rack.

WARNING

The front brackets must be secured to the rack. If the front brackets are left unsecured, the unit may shift forward and fall from the rack during installation or operation. Failure to secure the front brackets may result in personal injury and/or damage to the equipment.

To set up the U4600 in a desktop environment, place the U4600 on a flat surface where it will not be subject to spills or impacts. Also route cables to the unit so that they will not be hit or pulled, causing damage to the connectors or to the unit itself. Ensure a sufficient flow of cool air (See “Reduced Air Flow” on page13.) so that the unit's operating ambient temperature range is not exceeded.

WARNING

Locate the U4600 and its cables to avoid impacts, spills, and pulling cables and to ensure sufficient air flow. Failure to locate the U4600 in a proper environment may result in damage to the equipment.

2.4 Serial Port Configuration

Device assignments

The U4600 has one external serial port. A “device” must be assigned once to the serial port, but no “device” may be assigned more than once. In addition, more than one device may be assigned at one time but only one device which accepts input may be assigned. (If multiple devices are assigned to the serial port, the port’s settings are controlled by the device with higher priority according to the list below.) Device port assignment and device configuration (see below) may be controlled only from the unit front panel and the network may disable this capability. The possible devices are:

1. Terminal

2. Modem (“modem” being remote terminal via modem)

3. Local COMPEL



4. Auxiliary Data

5. Printer (including COMPEL e-mail and reports)

Device configurations

When a serial port configuration command is received, the specified configuration is immediately stored for the specified device (e.g. for the “Terminal” device). If a serial port is currently assigned another device, then its output buffer is immediately flushed and the port re-configured. Communication is fixed at 1 start, 1 stop, and 8 data bits, with no hardware handshaking. No provision for software handshaking is made in this Release. The serial port’s behavior for each of its device types is described in the following table. :

Table 2.6: Device Configurations

Device Serial Port Behavior (Italics are Programmable, Bold are Fixed)

Terminal Configured to 19.2k, N, 8, 1. The unit responds to the terminal commands as

described in 3.4 Operation from Local/Remote Terminal on page59.

Modem Configured to B, P, 8, 1. The unit responds to the commands as described in 3.4

Operation from Local/Remote Terminal on page59.

Aux Data Configured to B, P, 8, 1. This is an output only (all inputs ignored).

Local COMPEL

Printer Configured to B, P, 8, 1. This is an output only.

The legal values for B are: 1200, 2400, 4800, 9600, 19.2k, or 38.4 kilobaud. The legal values for P are: ‘O’, ‘E’, or ‘N’ for Odd, Even, or No parity.

Configured to B, P, 8, 1. This is an input for testing only.

800032-01 Rev. F 18 www.wegener.com

Device Handling Terminal I/O

The Terminal option is used for command and control of the U4600. The Terminal option provides a basic VT100-like terminal emulation. All I/O is prompted by user-input text strings terminated in carriage-returns. The Terminal, whether local or remote (via modem or telnet over TCP/IP), should be set to Local Echo On. The unit only echoes a carriagereturn/linefeed and then a ‘>’ prompt after user entry.

Modem I/O

The Modem option operates in a similar manner to the Terminal option. Where the Termi- nal option is limited to one specific configuration, the Modem option may be set to one of

several. The Modem option does not use special handshaking or special control characters, and only supports auto-answer modems.

To access the Modem command interface, the serial-port device must first be set to Modem. The "Terminal/IO" discussion above on emulation and echoing would then apply. When a user sends the U4600 unit a carriage return, it returns a prompt to "Enter modem password". Modem access is enabled if the correct password is entered. The U4600 outputs a welcome banner when modem access is enabled. After that, Modem I/O is indistinguishable from normal terminal access, and has the same restrictions on local user access that the Network has set for Terminal I/O.

UNITY 4600 USER’S MANUAL

Modem access is disabled when one of the following occurs:

1. A new input serial-port device is selected.

2. When no user input occurs for 10 minutes.

3. The OH command is received, or

4. The unit is reset.

Aux Data

The Aux Data option is defined to allow for async data streams to be carried within the transport stream and their raw payload output on an IRD serial port. The PID of these streams may or may not be assigned to a program number within a PMT. To recover the data, the IRD need only be given the PID and baud rate. The range of legal PIDs is established by ISO 13818 standard as 20 to 1ffe (hex). This may be performed either by COM-

PEL command or by the local user (if local control is enabled).

COMPEL

This option is defined to allow for input of the COMPEL control stream (for testing only). There is no output.

Printer Ouput

The Printer is an output-only option. There are three legal types of output for the Printer option: COMPEL-Requested Reports, COMPEL E-mail, and Raw COMPEL (binary) Data.

1. COMPEL-Requested Reports are IRD status reports identical to those that the

local user may request. These are always available for the Printer option.

2. COMPEL E-mail output type must be enabled by a non-volatile control.

www.wegener.com 19 800032-01 Rev. F

UNITY 4600 USER’S MANUAL

3. The last type, Raw COMPEL Data, must also be enabled by a non-volatile con-

trol. (Actually, it is a factory setting that can only be modified with debug access.) When this type of COMPEL data stream is being processed normally by the IRD host processor, it is also output as-is (in binary witn non-printing characters) to the Printer. While Raw COMPEL Data is being dumped, it has exclusive access to the Printer device, and no other outputs can access the printer until the dump has completed.

2.5 Installation Testing

The U4600 has a number of installation tests that may be performed from the front panel. From the Home screen, press the right arrow until the Installation Testing screen is displayed.

RF Input Check This test is used to verify an RF connection to a properly functioning LNB at any RF port.

Perform the check as follows:

a. Press ENT from the Installation Testing screen to bring up the RF Input Check

screen.

b. Press ENT again to display the input level estimate at RF Port 1. This will be an

average of the estimated levels at each of the twenty-four domestic transponder center frequencies.

Chapter 3 Operation

This chapter provides an overview of Unity 4600 operation, details of controls and indicators, the alarm/warning system, and user interface details.

3.1 Theory of Operation

UNITY 4600 USER’S MANUAL

Functional Summary

From one selected RF input feed, the Unity 4600 receives an L-band RF carrier from an external antenna LNB. It then demodulates the carrier and extracts the transmitted MPEG transport stream. If the stream is scrambled and the unit is properly authorized, it applies the descrambling algorithm to re-generate that transport stream as it appeared at the multiplexer in the uplink compression system. (Alternately, if using per-program viewing access, only the authorized programs will be descrambled.) This transport stream is then supplied to the ASI transport output, perhaps with program re-mapping or conditional DPI filtering (under network control). The U4600 also decompresses the components of a selected program and provides the audio, video, and/or data services for output.

NOTE: The user or network may wish to have a null program assignment if no

attempt at local decompression is desired. This is required for the new HD programming.

As needed, auxiliary functions are also provided, such as re-insertion of vertical blanking interval data (closed captioning for example) in the video output. Figure 3.1 presents a logical block diagram of U4600 operation.

Available outputs from the U4600 include:

• DVB-ASI transport output with program (number and descriptor) mapping

• Decompressed MPEG video as composite video output (NTSC or PAL)

• Two independent, decompressed audio streams (MPEG or Dolby AC-3 downmix) to balanced analog audio outputs

• Re-insertion of VBI line data from various proprietary and ATSC protocols

• Alarm relay

• User control relays for cueing

• DTMF cueing tones

• Front-panel audio (one stereo pair) and composite video monitor outputs

Automated Recovery

www.wegener.com 23 800032-01 Rev.F

If unable to deliver required services to predetermined standards, or if unable to detect a required network control stream (COMPEL), the U4600 attempts to resume normal opera-

tion through a process called Automated Recovery. Referring to an internal, non-volatile list of "presets", the U4600 will attempt to restore either services or network control, depending on what caused the recovery. A "preset" is a list of unit settings, and the list of these presets is called the Preset Table. Automated Recovery will attempt to restore the unit according to each preset (one at a time) in the order in which they are listed in the table. The process continues (repeating attempts if necessary) until the unit successfully resumes normal operation or is halted by local user command. If successful with a preset, the settings in that preset become the permanent unit settings. Later, the local user (or the network, if available) may abort the results of the Automated Recovery and force the unit back to its last commanded setting.

UNITY 4600 USER’S MANUAL

Several user- or network-programmable objects control the Automated Recovery. In addition to the contents of the Preset Table, these objects include the Services Recovery Timeout, the Network Recovery Timeout, the Recovery Iteration Time, and the Local Control Reenable Timeout. The first two timeouts control how long the unit will wait after loss of services or network control, respectively, before entering Automated Recovery. The Recovery Iteration Time sets the maximum time the unit will spend attempting recovery at each preset. The last is a special timeout for disaster recovery, such as loss of a satellite, where units whose local control was previously disabled by the network are re-enabled so that local users may implement more complex recovery plans.

Monitoring and Control

Most routine U4600 operations can be performed over Wegener’s COMPEL Network Control System. Control is "broadcast" to individual units through a "ghost-PID" data component of the incoming transport stream. The U4600 is considered disconnected from the network at any time this special stream is not being received.

In addition to the remote COMPEL network control, three methods are provided for "local" monitoring and control of the U4600:

1. A web browser interface (to be released August 2005);

2. a terminal interface (direct serial or via telnet over TCP/IP); and

3. a front-panel interface.

NOTE: Local control may be limited by COMPEL command.

The remainder of this chapter details these local monitor and control interfaces.

3.2 Operation from Front Panel

The U4600 front panel (Figure 3.2) includes the following four main parts: a liquid crystal display (LCD), six pushbuttons, eight LED indicators, and the front-panel audio and video monitor ports. Essentially all control available through the network or terminal is also available from the front panel.

The front-panel LCD (1) on Figure 3.2 supports unit monitoring and control by displaying screens containing status information, menu navigation pointers, and parameter input fields. Each LCD screen has a label or heading on the first row and information, parameters, or prompts on the second row which may cycle through multiple messages depending on the context.

The six pushbuttons (2) are your means of commanding the U4600 from the front panel. Use the four arrow buttons to navigate through menu screens and parameter selections and to scroll through available choices or characters when editing an input field. Press the ENT (Enter) button to select menus (downward navigation), to open editable input fields, or to commit edited parameters to the U4600. Press ESC (Escape) to

exit an input field without saving the entry or selection.ESC also provides upward navigation through the menu structure to the home screen.

UNITY 4600 USER’S MANUAL

LCD Screen Relationships

The eight front-panel LEDs (3) provide status information about your U4600 and its processes. See Table 3.2: Front- Panel LED Indicator Descriptions below for complete details. (Two additional LEDs are located on the rear panel and provide Ethernet status indications.)

At far right are the video port and audio port (4) included for monitoring from the front panel.

Figure 3.2 U4600 Front-Panel Layout

Figure 3.3 below shows LCD screen relationships from the

top level downward. These screens are structured in two dimensions, reflecting their relationships as peers, as parents, and as children of other screens. The up-and-down dimension represents the parent-child screen relationships (navigated with the ESC and ENT buttons). The side-to-side dimension is the peer relationship (navigated with the rightand left-arrow buttons).

A parent screen is usually a menu screen covering some category of U4600 operation or status. Its child screens are opened by pressing ENT at the parent screen. These child screens then provide access to finer details of unit monitoring and control. Multiple child screens of a parent menu screen are all peers to each other. However, the most significant set of peer screens are the top-level screens that have no parent and that include the home screen. The home screen may be reached by pressing and holding ESC (or pressing it repeatedly) from any

Home and Default Screens

The home screen appears on the LCD by default at boot up. During operation, the user may return to the home screen at any time, from any location in the menu hierarchy, by pressing the Escape (ESC) button repeatedly (or pressing and holding it). Regardless of the current location within the LCD menu hierarchy, if no front-panel keypress is made for more than 5 minutes, the LCD reverts to the default screen. Usually, this is the home screen. However, under some conditions (two are described below), another screen becomes the default. If more than one of these conditions exist simultaneously, priority is given in the order listed.

NOTE: Regardless of which screen is the current default, the user may still access

all available screens using the left- and right-arrow, ENT and ESC buttons.

Download Screen as Default

If the U4600 is in an ACCEPT PACKETS Download state, then the Download screen becomes default.

Audio FP Monitor Selection Screen as Default

For two minutes, or until ESC is pressed, the Level 2 Audio FP Monitor Selection screen is the default if the unit features a front-panel audio monitor jack and the user plugs in a ¼” stereo phone plug.

NOTE: This is NOT usually a first-level screen, unlike other default examples.

800032-01 Rev. F 28 www.wegner.com

UNITY 4600 USER’S MANUAL

On the Home screen, the (right-pointing arrow) field will quickly flash (a half-second ON and a half-second OFF) to signal the user that the right arrow button is active for user control. Pressing either the left or right arrow buttons will cause the U4600 to display the other top-level screens in succession. If there are current alarm and warning indications, the text "See Alarms" or "See Warnings" will appear before the arrow and pressing the right arrow will display the applicable alarm or warning message(s).

AUTH

GREEN constant A user cue relay is closed (energized).

GREEN flutter During a user relay “pulse” activation on any relay.

Off All user cue relays are open (de-energized).

RED constant One or more current alarm indications.

RED blink An alarm event has occurred in the past and has not been

acknowledged and cleared by the user. Note that this state may exist together with a current alarm (RED constant). In that case, the blink state is defined as quickly cycling OFF-ON-OFF (~100ms each) approximately every 2 seconds.

Off No alarm condition currently exists.

GREEN constant Unit has transport MPEG sync and the stream is not scrambled (in

the clear). Streams that are “clear” are always presumed to be “authorized”. OR: Unit is authorized for current scrambled transport stream (or selected program) and has transport MPEG sync. When using Wegener CA (’97 Version), being “authorized” means being addressed with current and valid ciphered keystream messages. In a PIN system, if the transport stream is scrambled, and the unit has been programmed with any key other than the null ‘00000’, then it presumes that it is “authorized”.

GREEN flutter Unit has successfully deciphered a valid descrambling seed in the

last five seconds. Normal behavior in functioning CA system.

Off Unit has transport sync, the transport stream is scrambled, and the

unit is NOT authorized. Also OFF if no transport sync.* LED states are defined as follows: Blink - alternating ON for ~100ms and OFF for ~2 seconds; Flash - alternating ON for ~500ms and OFF for ~500ms. Flutter - like flash but with shorter ~100ms ON and OFF times.

* LED states are defined as follows: Blink - alternating ON for ~100ms and OFF for ~2 seconds; Flash - alternating ON

for ~500ms and OFF for ~500ms. Flutter - like flash but with shorter ~100ms ON and OFF times.

Rear-Panel LEDs

The U4600 also has two LED (light-emitting diode) indicators on the rear panel. They provide the following indications:

LAN Green LED: ON if active LAN connection detected. OFF otherwise.

ACT Yellow LED: Flashing ON if ethernet packets are output or addressed packets are

input. OFF otherwise.

Front Panel Audio Monitor

To monitor audio output from the front panel, insert a 1/4-inch stereo phone plug into the audio monitor port. The U4600 will detect the phone plug and immediately display the Audio FP (front-panel) Monitor Selection screen. This second-level menu screen allows the user to select and monitor the desired audio stream. After two minutes without a keypress from the front panel, the U4600 will revert to the default LCD screen.

3.3 Operation from Local/Remote Terminal

UNITY 4600 USER’S MANUAL

Overview and Syntax

User Commands

This section applies to control by both the Terminal and Modem devices. Once a user has fulfilled the password requirement for Modem access, the communication is identical to Terminal control.

Approved clients for Terminal monitoring and control via telnet include Tera Term, Windows 2000 telnet, and Windows XP telnet and no special login is required. VT100 and

ANSI terminals are approved. To exit, use the client’s exit/escape sequence or get debug access in the IRD to use the QUIT or EXIT command.

Commands listed in this section detail command syntax and action taken. Commands consist of a command field and a parameter field. Each command field and parameter field is space delimited. Optional parameters are indicated by square brackets, [ ], and conditional parameters are indicated by braces, {}.

For example, COMMAND_NAME parameter1 {parameter2} [parameter3] indicates that parameter1 must be entered, parameter2 entered only when a certain condition is met (certain option is installed, etc.), and parameter3 is optional. Both commands and parameters may be entered in upper or lower case; the interface is not case-sensitive.

Incorrect or incomplete commands result in "Invalid Command" being displayed at the terminal. Parameter errors on User commands generate "Invalid parameter name" where parameter name is the name of the incorrectly entered parameter.

NOTE: Any commands controlling carriers, programs, or services may be disabled

from COMPEL



NOTE: Generally, any command that can control a unit setting may be entered

without parameters to show the current value of that setting.

Table 3.3: Command Directory for U4600 Terminal Commands

ABORT

Insert is terminated. See TEMP command.

ABORTREC x

x: C - make the unit’s permanent setting equal to the last commanded setting

S - make the unit’s permanent setting equal to the last successful setting

Command either

1) aborts an ongoing automated recovery;

2) aborts the successful results of an automated recovery; or

3) accepts the successful results of an automated recovery. With either value for x, this command is interpreted as a direct local user command to establish/confirm

the unit’s permanent settings.

The x is the one- or two-decimal-digit Product ID (also called the COMPEL download ID). 'yyy' are the last (least significant) digits of the unit serial number (most significant to left). The presumed subnet mask is 255.255.0.0 but the gateway is not defined. As an example, if a Unity 4600 with product ID=9 and SN=260050 is set to "Wegener" IP address mode, it's new static IP address becomes 172.16.90.50.

To fix possible address contention, the IRD, when the application initializes, attempts to detect an IP address conflict (using ARP). If a conflict is detected, the unit adds one hundred (decimal) to the last field of the attempted IP address and tries again. Using the above example, if 172.16.90.50 has already been assigned on that LAN, then the IRD re-attempts with an IP address equal to 172.16.90.150.

LAN SUBNET addr

addr: IP address formatted as n1:n2:n3:n4 where n1, n2, n3, and n4 are integers between 0 and

255. Note that not all values can be legal.

Command sets the IRD’s static subnet mask address. Command entries that do not assert legal IP address masks will be rejected. Omitting the addr parameter shows the current static subnet mask. This will not be the current subnet mask if dynamically assigned. Use IPCONFIG command for that. A Local Control Command (available from the terminal regardless of "Local Control Enable/Disable" commands from the network).

LATCHALARMS x

x: Either E for Enable, or D for Disable.

Command enables or disables the latching of unit alarms.

LNBPWR output

parameter: One of format, feed, freq [for “carrier freq”], rate [for “data rate”], FEC, tag [for “tag site”],

prog [for “program”], margin [for “Eb/No margin warning zone”], aud1, or aud2 [for

“descriptors assigned to audio ports 1 and 2”]. See PERM and ADDE commands for definitions and limits.

value: Value of the parameter as in any settings command (PERM, TEMP, ADDS, etc.) destination: PERM, TEMP, number or label of a Preset table entry. time: Length of insert in either HH:MM:SS format (valid range is 0:00:00 to 18:00:00, leading zeros

OK to omit on hours) OR in number of seconds. (A one-hour TEMP could have a parameters: of 1:00:00 or 3600.)

source: PERM, CURR, number or label of a Preset table entry.

SET sets the value of individual parameters in a ‘scratch pad’ settings group. SET TO will store the scratch

pad settings to a search table entry or to the permanent or temporary settings (requires an insert time as a second parameter). SET FROM loads the scratch pad settings from a search table entry or from the current or permanent settings.

SETAUDIO port route [program] [atten]

port: Value of 1 to 6 indicating an audio port

route: S - Stereo (Left and Right components routed as connected at original MPEG encoder)

1 - Original Left component to both L and R outputs 2 - Original Right component to both L and R outputs M - Sum of Left and Right components to both L and R outputs R - Reverse of “Stereo” above (if allowed by hardware)

program: Can be a three character name or an ‘*’. If the 3-character name is specified, the unit will

route the audio PES stream with the specified name to the port. If ‘‘*’ is specified, the unit will default to the first audio program in the PMT that is not routed to another port.

atten: Must be a numeric value for attenuation in dB. Legal values are given in Table1.1 on

page3. This programs the net audio attenuation, where ‘0’ gives 0dB attenuation (maximum level). If field omitted, attenuation remains unchanged on that audio port.

The audio PES stream, with the language descriptor program, is decompressed in the port audio port, and then its components are routed to the Left and Right outputs according to route. That ports attenuation is changed to atten, if supplied.

SETLABEL label

label: Unit label. Field entry is truncated at 10 characters.

CHAPTER 4 MAINTENANCE AND TROUBLESHOOTING

4.1 Maintenance

Maintenance of the Unity 4600 is limited to keeping the chassis clean and ensuring that all the cables remain firmly connected. Occasionally wipe the exterior with a soft, damp cloth to remove any accumulated dust and dirt, and check that the cables are securely attached.

The Unity 4600 incorporates security labels over some of the screws. There are no user-serviceable components within the U4600. Tampering with the security labels or opening the unit will void your warranty. If you have any questions, contact Wegener’s Customer Service Department at the address or numbers listed under Customer Service.

4.2 General Troubleshooting

This section is not intended as an exhaustive list of all possible situations, but a list of the most common installation problems. Please contact us (see Chapter 5, Customer Service), with any problems you cannot resolve independently.

If you are experiencing any difficulties, first check the LED indicators on the U4600 front panel. See Table 3.2: Front-Panel LED Indicator Descriptions on page 29 for details about the LED indicators. Note that during typical operation, the green CAR-

RIER, TRANSPORT, COMPEL, SERVICES, and AUTH LEDS should be on.

No Output, LCD, or LED Indications

No Audio, Video, or ASI Output

If the unit provides no output and neither the LCD nor any LEDs are lit, there is either a loss of AC power or the internal power supply has failed. Do the following:

a. Check that AC power cord is firmly connected at both ends.

b. Check that your AC power source is supplying AC power.

c. If both checks a. and b. are okay, contact Customer Service (see Chapter 5)

before returning the unit for service.

Alarm LED On and Carrier LED Off

1. If the first front-panel alarm message is "No RF Signal", then the U4600 is unable

to lock to an RF carrier at the selected RF port. Check the following items:

a. Either the outdoor antenna LNB is not operating or is not connected to the

IRD at the selected RF port. To rule these out, verify that the LNB (and any

www.wegener.com 47 800032-01 Rev. F

UNITY 4600 USER’S MANUAL

b. The selected IRD RF port has failed. To rule out this possibility, try connecting

c. The IRD receiver card has failed. To rule this out, try using another IRD.

2. If the first alarm message is “No Carrier Lock”, verify the RF Feed Port, Carrier Frequency, Data Rate, FEC Ratio, and ID Tag (if Tags are in use) settings. Also verify that the LNB LO frequency setting (in the IRD) is correct for the selected RF feed port.

3. If the alarm message is “RF Signal Overload”, then reduce the carrier power entering the U4600. Either add in-line attenuation (a splitter will do) or remove line amplification in the RF circuit between the LNB and the IRD.

Alarm and Carrier LEDs Both On

intermediate line amplifiers) has DC power and trace the connection from the LNB to the IRD or try replacing the LNB. If a spectrum analyzer is available, look for the carrier at the L-band intermediate frequency. (For domestic Cband satellites, this is 5150 minus the downlink frequency in MHz.)

the RF cable to another RF port and select that port (or use the RF Switch Bypass to force that other port).

Missing an Audio, Video, or ASI Output With Other Outputs Okay

The U4600 may not be authorized for the network’s Conditional Access. If the AUTH LED is Off and the alarm message, "Unauthorized for CA” appears, contact your network provider to gain authorization in its Conditional Access database.

Alarm or Warning LED On

Check the front-panel display for alarm or warning messages. Table 4.1: Alarm and Warning Descriptions on page49 describes U4600 alarm and warning messages. If

the message definitions are too technical to help debug the problem, report the messages to your network provider.

Alarm and Warning LEDs Off

If no alarms or warnings are shown, suspect a bad connection or mis-programming of the U4600:

1. If audio or video are missing, check the front-panel monitor jacks. If the front monitor connections are OK, check the signal connections from the rear of the unit to the destination. If an audio is missing from the rear-panel outputs and cannot be detected at the front-panel monitors, check that a valid audio stream is selected for that port and that the network provider has supplied non-quiet programming on that audio.

2. If the ASI output is missing, check the signal connections from the rear of the unit to the destination. If okay, check with the network provider to verify what Program Mapping (Release 2 or later) may be in effect.

800032-01 Rev. F 48 www.wegener.com

4.3 Alarms and Warnings

The alarm and warning system is intended to alert the local user of a present or impending loss of services. Table 4.1 below lists many (but not all) of the possible alarm and warning messages that the U4600 may display. For problems you cannot resolve on your own, please contact Wegener Customer Service (see Chapter 5), and be prepared to describe your signal setup, U4600 configuration, and any displayed alarm and warning messages.

Alarms

An alarm is asserted when the unit is unable (or presumed to be unable) to perform a required function or deliver required services.

Warnings

A warning is asserted when an alarm condition is imminent or to indicate other conditions requiring user attention.

Table 4.1: Alarm and Warning Descriptions

LCD Alarm or Warning

Message

Meaning / Possible Cause

Auto-Recovery Auto-recovery in progress. This may be caused by any of the following

problems on a previously commanded or successfully acquired transport stream:

1. IRD unable to deliver services for time exceeding Services Recovery Timeout;

2. IRD required to maintain connection to COMPELand IRD has not detected COMPEL for time exceeding Network Recovery Timeout; or

3. IRD detects invalid incoming COMPEL header.

Bad Audio N PTS

Excessive jumps or jitter in Audio port N PTS values

(N=audio port number)

Bad PMT One or more Program Map Tables are corrupted. See "No PMT" indication. Bad Sec Micro SN Serial number read from secure processor does not match unit. There may be

a an attempt at piracy, a defective NVRAM memory, or a defective secure processor.

Bad VBI Data FN LM

(N=field number;

VBI data for field N, line M is unrecognized or in an unsupported format. Contact TOC to confirm that the version of application code in your IRD is current.

M=line number) Bad Video Data Video PES stream appears to be invalid. Check if other IRDs see similar

problem on the same program.

Bad Video PTS Excessive jumps or jitter in video PTS values. There may be a defective uplink

encoder or mux.

Content for ASI N/A Program content requested to route to ASI output cannot be found in over-

satellite transport mux. Contact network TOC and advise.

Content Routing Problem

ASI transport output bears no program content because a Content Routing Table has not been loaded from the network or is corrupt. Contact network TOC.

Eb/N0 Margin Warning Eb/N0 value less than sum of Threshold + Margin—evaluated over 10 sec.

intervals. Unless the margin setting is incorrect, this indicates a marginal downlink.

FP Email Fail An FP Email message was received which was corrupt or invalid. User should

acknowledge the warning to clear, and then notify the network TOC.

High Error Rate High errored seconds rate, presumably useless signal—evaluated over 60 sec.

intervals. Signal-to-noise ratio is insufficient or there is severe terrestrial or antenna cross-pol interference.

High RF Level There is carrier lock, but the RF signal level is too high. ID Tag Mismatch Carrier ID frequency text mismatch. User or network has entered carrier

frequency text or tag site ID incorrectly or unit is on the wrong carrier.

ID Tags Lost Carrier ID tags disappeared. There may be a failure at the uplink inserter

(UMX5010) or loss of COMPEL PID. See "ID Tag Mismatch" indication.

800032-01 Rev. F 50 www.wegener.com

Table 4.1: Alarm and Warning Descriptions

UNITY 4600 USER’S MANUAL

LCD Alarm or Warning

Message

Meaning / Possible Cause

Invalid COMPEL Hdr Invalid COMPEL header detected in incoming COMPEL messages. This will

cause the unit to immediately attempt automatic recovery to a backup preset. The IRD is not set up for connection to this COMPEL system.

Invalid VBI Data Fmt VBI data found in PID or video user data in unrecognized or unsupported format

(protocol).

Invalid Video Format Video format in requested program is not supported. IP Address Conflict LAN detected but cannot use because of IP address conflict. KMS Stream Lost KMS stream lost after initially detected in this transport stream. There could be

an uplink problem. See also "No KMS stream" indication.

Lost COMPEL PID Data traffic at designated packet ID (PID) for COMPEL has been lost for more

than two minutes. See "No COMPEL" indication.

Lost VBI Data FN LM

(N=field number;

VBI data for field N, line M has disappeared. If any is expected, contact network TOC.

M=line number)

Low RF Level There is carrier lock, but the RF signal level is too low. New PAT with Changes The version number on the Program Allocation table has changed and a new

program lineup has been submitted. Changes have been made on uplink transport mux.

New PMT with Changes The version number on one or more of the Program Map Tables has changed

with a new PID lineup submitted. Changes have been made on uplink transport mux.

No ASI Stream Corrupt or missing input ASI stream. Only applicable if ASI input is available and

selected. Check connection and source.

No Audio for Port N

(N=audio port number)

No "free" otherwise-unassigned audio can be allocated to wildcard-assigned port N. There may be fewer audio PES streams than installed audio ports. If so, explicitly assign a desired language descriptor to this audio port.

No Carrier Lock Carrier lock cannot (or has not) been acquired and maintained. Check that

requested settings are correct. Check RF level indication and RF connection. For new installations, check antenna pointing and polarization.

No COMPEL

Data traffic is detected at designated packet ID (PID) for COMPEL. However, no valid COMPEL messages have been detected during the last two minutes. There may be no connection to the network. If required to maintain a connection, the unit will eventually attempt an automatic recovery to a backup preset. To debug, check that the COMPEL system at the uplink is functional and that the data connection to inserter (such as UMX5010) is good. Also check for fault indications or functional problems at UMX5010.

No COMPEL PID No traffic detected at designated packet ID (PID) for COMPEL, so no

connection is made to the network. The COMPEL PID setting in the unit may be incorrect. Also see "No COMPEL indication".
