2.4 Serial Port Configuration

selectable between audio ports 1 or 2

Device assignments

Device configurations

The Unity 4600 has one external serial port. A “device” must be assigned once to the serial
port, but no “device” may be assign ed 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 d evice (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:

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.

T erminal I/O - The Terminal device is used for command and control of the Unity 4600. This
I/O is a basic VT100-like emulation. All I/O is prompted by user-input text strings terminated
in carriage-returns. The ter minal, whether local or remote (via modem or telnet over TCP/
IP), 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 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. The user wo uld send the u nit
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

Unity 4600 will output a welcome banner. Af ter 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 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 the ISO 13818 standard as 20 to 1f fe (hex) . This may be performe d either by

COMPEL® - This device is defined to allow for input of the COMPEL cont rol 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 the local user may
request. These are always 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 non­printing 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 extract s 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 u sing
per-program viewing access, only the authorized programs will be descrambled.) This
transport stream is then supplied to the ASI transport output, perhap s with program re­mapping or conditional DPI filtering (under network control). The

Unity 4600 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 examp le) in the video output.

3.1 presents

a logical block diagram of Unity 4600 operation.
Available outputs from the Unity 4600 include:

 DVB-ASI transport output with program
 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

(number and descriptor) mapping

Automated recovery

If unable to deliver required services to predetermin ed standards, or if unable to d etect

®

a required network control stream (COMPEL

), the Unity 4600 attempts to resume
normal operation through a process called Automated Recovery. Referring to an
internal, non-volatile list of "presets", the

Unity 4600 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 th e unit ba ck to its last commanded setting.

wegener.com 800032-01 Rev. G 27

Operation

Several user- or network-programmab le obje cts control the Aut om a te d Rec ov er y. 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 local users may implement more complex recovery plans.

Monitoring and control

Most routine Unity 4600 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

Unity 4600 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

Unity 4600: a web browser interface (later release), a terminal

interface (direct serial or via telnet over TCP/IP), and 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.

Home and default screens

The home screen appears on the LCD by de fault at boot up. During operation, the user may
return to the home screen at any time, from any location in the menu hierarchy, by pr essing
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 de fault. 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 Unity 4600 is in an ACCEPT PACKETS Download state, then the Download screen
becomes default.

32 800032-01 Rev. G www.wegener.com

Unity 4600 User’s Manual

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 mon itor jack an d the us er plug s 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

Unity 4600 to display the

other top-level screens in succession. If ther e are current alarm and warning indicatio ns, 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).

3.3 Operation from Local/Remote Terminal

Overview and syntax

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

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.

A Local Control Command (available from the terminal regard less of "Local Control Enable /
Disable" commands from the network).

INDPERS indication time

indication: A or Alarm or W for Warning.
time: Time in seconds.

Command to set the minimum indication-time persistence for eith er Alarms or Warnings, per the value

of indication, for the time period given by time. Entering command without parameters
shows the current settings. A Local Control Command (available from the terminal
regardless of "Local Control Enable/Disable" commands from the network).

IPCONFIG

Command requests report of all current IP parameters (I P address, Gateway address, subnet mask) and

assignment mode (static or DHCP). A Local Control Command (available from th e terminal
regardless of "Local Control Enable/Disable" commands from the network).

LAN GATEWAY addr

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

255.

Command sets the IRD’s static internet Gateway IP address. No protection is offered against entry of

non-standard addresses (e.g. 0:0:0:0). Omitting the addr para meter shows the current static
Gateway IP. This will not be the current Gateway IP address if dynamically assigned. Use
the

IPCONFIG command for that. A Local Control Command (available from the terminal

regardless of "Local Control Enable/Disable" commands from the network).

LAN IP addr

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

255.

Command sets the IRD’s static IP address. No protection is offered against entry of non-standard

addres-ses (e.g., 0:0:0:0). Omitting the

addr parameter shows the current static IP. This will

IPCONFIG command for that.

A Local Control Command (available from the terminal regard less of "Local Control Enable /
Disable" commands from the network).

Operation

LAN MODE mode

mode: DHCP, WEG, or STATIC.

Command sets the IP configuration to either dynamic DHCP, "Wegener" mode, or static IP addresses.

If static, see

LAN IP, LAN GATEWAY, and LAN SUBNET commands. Omitting the mode

parameter shows the current mode. This is a Local Control Command (available from the
terminal regardless of "Local Control Enable/Disable" commands from the network).

Assigning "Wegener" mode IP address forces the assignment of a static IP address for testing. This

address is of the form: 172.16.xy.yy. 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 255.25 5.0.0 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

output: Either ON or OFF.

Non-volatile command enables or disables LNB DC power ind ependently o f any other se ttings. A Local

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 exterior 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
labels or opening the unit will void your warranty. If you have any questions, contact

for details about the LED indicators. Note that during typical operation, the green

CARRIER, TRANSPORT, COMPEL, SERVICES, and AUTH LEDS should be

on.

No output or indications

No audio, video, or ASI output

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

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

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

3. If both checks a) and b) are okay, contact Customer Service (see Chapter 5) before
returning the unit for service.

LEDS: ALARM ON and CARRIER OFF

The Unity 4600 is unable to lock to an RF carrier at the selected RF port:

1. If the first front-panel alarm message is "No RF Signal", then: (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 inte rme diate 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 selec t that port (or
use RF Switch Bypass to force that other port). To rule out (3), 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

LEDS: ALARM or WARNING ON
Check the front-panel display for alarm or warning messages. Table 4.1: Alarm and

Warning Descriptions on page 53 describes Unity 4600 alarm and warning messages. If

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

LEDS: ALARM and WARNING OFF
If no alarms or warnings are shown, suspect a bad connection or mis-programming of the

Unity 4600:

1. 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-pan el
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.
