1.2 U4600 Overview

Functional
Description

The Wegener Model Unity 4600 Digital Media Receiver/Decoder 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 rat e s 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 AC-3 audio

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

•Audio-only mode option for radio networks

•Alarm relay

•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 (August 2004)

Physical
Description

The U4600 is housed in a standard, 1 RU, rack-mountable chassis. Its front
panel (see

Figure 1.1 The Unity 4600 Digital Media Receiver/Decoder

) pro­vides a user interface through six push buttons and an LCD as well as monitor­ing through both 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.

1.5 Glossary of Terms and Abbreviations

Table 3: Glossary of Terms

Term Definition

Ad avail, digital The opportunity for a local program splicer to insert local content in the MPEG PES

streams in substitution for “regular” network-distributed programming. The avail is
bounded by “splice out” and “splice in” points. "Splice points" are seamless insertion
points (located for the splicer by DPI messages) where the compressed stream may be
broken and substituted without frame-by-frame interruption of video.

Ad avail, analog The opportunity for local users to switch from the network-supplied programming to

locally-generated content (commercials). This is signaled by use of DTMF tones or clo-

sures of cue relays.
Alarm A condition or notification of a condition that prevents proper U4600 functioning.
Application Software The main host software which sets up the unit hardware, runs the process of acquiring

transport stream sources, sets up and monitors the demux and decompression processes,

monitors unit operations, and interfaces with the network and local users.
ASI (or DVB-ASI) An “asynchronous” bit-serial physical interface for transport streams. Transmitting and

receiving functions are designed such that the time relationships between all packets and

their timing references are unchanged.
Audio Language

Descriptor

800032-01 Rev. C 18 wegener.com

Legacy 3-character MPEG descriptor applied to a program’s audio streams. It was origi-

nally allocated to designate languages, but is now used for generic identification.

Automated Recovery
(or Recovery)

The mechanism used when the U4600 is unable to acquire a valid transport stream, loses

network control or detects an invalid control stream, or is unable to deliver the required

services using its current settings. The unit automatically begins attempting operations

under "backup" unit settings stored in the presets table until it can return to normal op era-

tion or is stopped by local user command.
Boot loader Software residing in non-writable zone of flash which executes at unit reset. It will verify

and load the preselected application.
CA See "Conditional Access".

COMPEL



Wegener's network control software that may be used to manage your U4600 as well as

other hardware.
Conditional Access Wegener’s system for securing the transmitted transport stream from unauthorized

access. It features distribution of ciphered authorizing messages within a special PID.

Upon deciphering in secure processors within the IRD, these messages continuously

update the IRD with the current descrambling key.
DPI Digital Program Insert. A special message, borne in an MPEG PID associated with a par-

ticular program, that signals the boundaries of ad avails.

to control external cueing equipment.
DVB Digital Video Broadcast working group. This is a shorthand designation for a group of

industry standards that provide en hancements in th e use of MPEG transport st reams. (For

example, one DVB standard defined the standard way QPSK-modulated carriers would

convey these streams over satellite world-wide.)
E

b/N0

Energy-per-bit per Noise density-per-Hertz. This is a unitless ratio that expresses signal-

to-noise ratio in carrier transmission systems that convey digital data. A quality measure-

ment for any such system is the E

acceptable error rates. This is called the “E

needed to just convey the digital data within

b/N0

threshold”.

b/N0

Ethernet The widely-used LAN technology specified by IEEE standard 802.3
IRD Integrated Receiver-Decoder. A product which features a "receiver" to extract transport

streams from satellite-borne carriers and a companion "decoder" to decompress MPEG

elementary streams (from within said transport streams) in order to recreate the original

audio/video/data signals. The Unity 4600 is an IRD.
Keep-alives

(COMPEL)

Simple COMPEL network messages, addressed to "all", bearing date and time.These are

transmitted regularly (every 5 seconds, for example) so that IRDs may quickly and con-

tinuously verify their network connection.

Mechanical Loading
Mounting of the equipment in a rack should be such that a hazardous

condition is not produced by uneven loading. This unit is not very heavy, but
total rack loading must be considered. Also, do not rest any unsupported
equipment on your U4600.

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.

Installation

Your U4600 is sized at a single RU and will fit an EIA-standard, 19-inch-wide
equipment rack.

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 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 page 24.) so that the unit's operating ambient temperature range is not
exceeded.

2.4 Serial Port Configuration

Unity 4600 User ’s Manual

Device
assignments

Device
configurations

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)

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:

Device
handling

Terminal I/O

- The Terminal device is used for command and control of the
U4600. This I/O is a basic VT100-like emulation. All I/O is prompted by user­input text strings terminated in carriage-returns. The terminal, whether local or
(via modem) remote, should be set to local echo ON. The unit only echoes a
carriage-return/linefeed and then a ‘>’ prompt after user entry.

Modem I/O

- The Modem device operates in a similar manner to the Terminal
device. Whereas the Terminal device was limited to a specific configuration,
the modem device may be set to one of several. The Modem device does not
use special handshaking or special control characters, and only supports auto­answer 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. The user would send the unit a car­riage return and then the unit would return a prompt to enter the "modem pass­word". If the correct password is entered, then modem access is enabled. Upon
enabling modem access, the U4600 will output a welcome banner. After that,
I/O is indistinguishable from normal terminal access, with the same restriction
on local user access as set by the Network. Modem access is disabled when
either (1) a new input serial-port device is selected, ( 2) when there is no user
input for 10 minutes, (3) the OH command is received, or (4) the unit is reset.

Aux Data

- The Aux Data device is defined to allow f or a sync data stre ams 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. T o recover the data, the IRD need only be given the PID
and baud rate. The range of legal PIDs is established by the ISO 13818 stan-

dard as 20 to 1ffe (hex). This may be performed either by COMPEL com­mand or by the local user (if local control is enabled).

COMPEL



- This device is defined to allow for input of the COMPEL control

stream (for testing only). There is no output.

PRINTER OUTPUT

- This is an output-only device. For the Printer device,
there are three legal types: COMPEL-requested Reports, COMPEL E-mail,
and Raw COMPEL (binary) Data. The first output type are IRD status reports
identical to those that th e local user may request. These are alw ays available
for the Printer device. The second output type must be enabled by a non-vola­tile control. The last type, Raw COMPEL, must also be enabled by a non-vola­tile control (actually a factory setting that can only be modified with debug
access). It is exclusive of the other outputs (the others are not allowed if dump­ing Raw COMPEL). For this type, the COMPEL data stream, while being pro­cessed normally by the IRD host processor, is also output as-is to the Printer
device. This data is binary and includes non-printing characters.

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

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 authoriz ed
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:

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

Available outputs from the U4600 include:

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

presents a logical block diagram of U4600 operation.

•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 A TSC protocols

•Alarm relay

•User control relays for cueing

•DTMF cueing tones

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

Automated
recovery

wegener.com 35 800032-01 Rev. CCCC

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 operation 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

Unity 4600 User’s Manual

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 sett ings in that preset becom e 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.

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 Re-enable 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 l oca l use rs ma y impleme nt mor e co mple x re cover y
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: a web browser interface
(later release), a terminal interface, and a front-panel interface.

NOTE:

Local control may be limited by COMPEL command.

The remainder of this chapt er details these local monitor and contr ol interf aces.

3.2 Operation from Front Panel

Front-panel
layout

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, see

tionships

on page 39) supports unit monitoring

LCD screen rela-

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.

The eight front-panel LEDs (3) provide status
information about your U4600 and its processes.

LCD screen
relationships

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 right- and 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 scree ns that have no par­ent and that include the home screen.

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 Selec-

tion 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 that this is NOT usually a
first-level screen, unlike other default examples.

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).

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.

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.

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

Overview and
syntax

The following discussions apply 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.

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.

User
commands

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.

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.

dB (to tenths of a dB). N is defined by individual IRD specifications for every
modulation/FEC combination.

Command sets the Margin Warning point. This provides warning to local users
that their Eb/No’s are approaching the error-threshold where system perfor­mance will collapse. (Supersedes SNR command.) A Local Control Command
(available from the terminal regardless of "Local Control Enable/Disable"
commands from the network).

MOVEP source destination

source: Preset Table entry number which will source Unit settings.

destination: Preset Table entry number to which the Unit settings will be

moved.

Command moves the Unit settings at the source entry to the destination entry.
The setting data at the original source entry is deleted and that entry position is
now considered unused. The setting data at the original destination entry is
then moved to the next lower unused Preset position. (One will always be
available because the entry that held the original source settings was made
“unused”.)

SAVEP [entry#] [channel_label]

entry#: A Preset Table Entry number or the text, "PERM". If a preset entry,

must be equal to number between 1 and N inclusive, where N is highest entry
number.

channel_label: Channel Label associated with a unit setting or a Preset Table
entry. If attempting to supply the channel_label parameter alone, a value of
"PERM" is not legal. Parameter must be a string of continuous non-white­space keyboard characters. Unit will truncate user input to 10 characters.

Command saves current Unit Settings to a Preset Table entry, or if entry# is
"PERM", a current Transient Setting is loaded into the unit's Permanent unit
setting. Those metadata fields in the extended Preset Entry that have no analog
in the current Unit setting will be populated with spec defaults. User must use
ADDE to set those fields.

If entry# is supplied alone, current unit settings are written to that entry, over­writing existing data if it had been in use. If channel_label is supplied alone,
and if that same Label already appears at a used Preset Table entry, then the
current unit settings overwrite that old Preset data. If channel_label is supplied
alone and no used Preset has that Label, then the current settings are written to
the lowest empty Preset Table entry and then given that same Label. If both
entry# and channel_label parameters are supplied, then the current unit set­tings are written at that Entry (overwriting existing data if any) and that entry is
supplied that same Label (equal to channel_label).

SET [parameter] [value]
SET TO [destination] [time]
SET FROM [source]

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 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 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 per-

manent 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 con-

nected 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.

Unity 4600 User’s Manual

atten: Must be a numeric value for attenuation in dB. Legal values are given in
individual IRD specifications. 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.

Sets Unit Label displayed on IRD home LCD screen (and Terminal Welcome
Banners).

SETLNB {rf_feed} {LO_freq}

Rf_feed: If the RF Switch expansion option is installed, this is one input to that

switch (1 through 4). If no RF Switch option is installed, then it is an error to
enter data here!

LO_freq: Either a number or mnemonic. If a number, this value represents the
LNB LO frequency in MHz. It can have up to two decimal places and its valid
range is from 0 to 14000.00. The legal mnemonics are “C” (for Standard C­band, 5150 MHz default), “KU” (for US Ku-band, 10750 MHz default),
“EHKU” (for European Hi Ku-band, TBD MHz default), or “ELKU” (for
European Low Ku-band, TBD MHz default).

(1) If the current LNB mode selected is Universal: This command is legal only
when entered without parameters. In this case, the IRD returns the current cal­culated setting command sent to the LNB (either “9.75 GHz” or “10.60 GHz”).

(2) If the current LNB mode selected is LO: This command sets the assumed
LNB LO frequency to the value entered in MHz OR the MHz value repre­sented by the mnemonic. If there is an optional RF switch installed, then the
rf_feed field data must be entered. Entering the command without parameters
returns the current setting.

Chapter 4 Maintenance and Troubleshooting

4.1 Maintenance

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

Table 7: Front-panel LED Indicator Descriptions

No output or
indications

U4600 front panel. See
page 43 for details about the LED indicators. Note that during typical opera-

tion, the green CARRIER, TRANSPORT, COMPEL
AUTH LEDS should be on.

If the unit provides no output and neither the LCD nor any LEDs are lit, there
is likely 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.

No audio,
video, or ASI
output

LEDS: ALARM ON and CARRIER OFF

The U4600 is unable to lock to an RF carrier at the selected RF port:

a) If the first front-panel alarm message is "No RF Signal", the n: (1) either

the outdoor antenna LNB is not operating or is not connected to the
IRD at the selected RF port; or (2) the selected IRD RF port has failed;
or (3) the IRD receiver card has failed. To rule out (1), verify that the
LNB (and any 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 C-band satellites, this is 5150
minus the downlink frequency in MHz). To rule out (2), try connecting
the RF cable to another RF port and select that port (or use RF Switch
Bypass to force that other port). To rule out (3), try using another IRD.

b) If the first alarm message is “No Carrier Lock”, verify the RF Feed

Port, Carrier Frequency, Data Rate, FEC R atio, 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.

Missing an
audio, video,
or ASI output
while others
are okay

c) 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.

LEDS: ALARM ON and CARRIER ON

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

LEDS: ALARM or WARNING ON

Check the front-panel display for alarm or warning messages.

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

800032-01 Rev. C 70 wegener.com

LEDS: ALARM and WARNING OFF

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

a) If audio or video are missing, check at the front-panel monitor jacks. If

okay on the front monitors, 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.

b) 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.

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. The tables below list 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.

Appendix A Monitoring and Control Details

A.1 Basic Navigation

Monitoring and control of the U4600 from the front panel is accomplished by
first navigating to the appropriate screen for the desired function (see

screen relationships

and contents). Press ENT to move downward through menus and screen levels
and ESC to return upward through the scre en structure. Press the right- and
left-arrow buttons to move between peer screens. The home screen may always
be reached by pressing and holding the ESC button or by pressing it repeatedly.

A.2 Info Screens

Info screens are read-only and display information that cannot be edited. The
home screen is this type of screen. Other screens of this type display U4600
status or navigation helps.

For info screens like the Software Application Version screen shown below,
the text on the second row will contain the current information (the software
version in this example). If no key presses are made, after a brief delay , the sec­ond row begins alternating between this content and the following navigation

A.4 Parameter Screens

Parameter screens display a specific pa ramete r that can be edited (if the correct
authority has been established). Such screens contain an alphanumeric or list­select field. There are no carries or borrows when wrapping on a numeric field
(i.e. to go from 0999 to 1000, 4 digits must be edited).

For parameter screens like the Unit Label screen below, the second row con­tains the current value of the parameter. Upon pressing ENT, a blinking under-
score appears under the first character to be edited (Only for editable
alphanumeric fields. List-select fields will not display a cursor). Use the arrow
buttons to scroll through characters or list selections. Af ter making the de sired
change, press ENT again to commit the entry to the U4600. Press ESC if you
wish to cancel the change. If no key presses are made, after a brief delay, the
