DTV 735 User’s Manual
800021-01 Rev. B 12 wegener.com
DANGER
To avoid damage to this and other equipment, or personal injury, the following
items should be strictly observed.
Elevated Operating Ambient
When equipment is installed in a closed or multi-unit rack assembly, the
operating ambient of the rack environment may be greater than the room
ambient. Therefore, consideration should be given to the ambient air
temperature within the rack, and not just inside the room, when deciding if the
maximum recommended ambient operating temperature (TMRA) is being met
or exceeded.
Reduced Air Flow
Equipment should be installed such that airflow required for safe operation of
the equipment is not compromised.
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 DTV735.
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.).
DTV 735 User’s Manual
wegener.com 13 800021-01 Rev. B
Rack
Mounting
Your DTV735 is sized to fit in 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 DTV735 on its supports and use four anchor screws or bolts
and nuts to secure the unit’s front brackets to the rack.
c) Connect the chassis grounding screw to an earth ground before
connecting the power cord to the unit.
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.
WARNING
Locate the DTV735 and its cables to avoid impacts, spills, and pulling cables
and to ensure sufficient air flow. Failure to locate the DTV735 in a proper
environment may result in damage to the equipment.

Ethernet An Ethernet 10BaseT/100BaseT port is included and is the primary user inter-
face using an HTML browser-based interface. The unit has an URL which is
assigned via the front panel. The “home” page is then accessed by users via the
Ethernet port. From this page, the desired channel selections may be performed
and status monitored.
Terminal I/O The Terminal serial port is configured to 115.2k, N, 8, 1. The Terminal device
is used for command and control of the DTV735. This I/O is a basic, VT100-
like emulation. User input text strings terminated in carriage-returns prompt all
I/O. The terminal should be set to local echo ON because the DTV735 only
echoes a carriage-return/linefeed and then a ‘>’ prompt after entry of a com-
mand-line terminated in carriage-return.

Chapter 3 Operation
3.1 Operation Overview
This chapter contains detailed operating instructions for your DTV735. The
following sections address:
• Ethernet/Web Browser Control
• DTV735 Controls and Indicators
• Front-panel Operation
• Initialization
• Transport Stream Processing
• Alarm System
• Software Downloads
Local user control is from a LAN via RJ-45 Ethernet or the front-panel LCD/
keypad. All settings may be presumed to be retained through power cycling
unless otherwise specified. This means that they are still in effect through
resets, whether by power outage, commanded reset, or failure-recovery resets.
3.2 Ethernet/Web Browser Control
The DTV735’s primary user interface is from a web browser using the rear-
panel Ethernet LAN connection. An HTML script interface allows a user to
control and monitor the unit using a standard web browser. Each unit contains
a user-defined quad URL address, subnet mask, and gateway address (See
Table 4: DTV735 IP Setup).
There are two basic methods of using the Ethernet connection – with a directly
connected PC or with a PC connected through a LAN.
Directly
connected PC

Using the
Web Browser
To begin monitor and control functions from a PC or LAN connection:
a) Open the current internet browser of your choice from the local PC or
computer on the LAN attached to your DTV735.
b) Set the browser's address field to http://nnn.nnn.nnn.nnn where
nnn.nnn.nnn.nnn is the IP address of the unit to be controlled (set from
the DTV735’s front-panel, IP Address screen).
NOTE: For IP addresses which include subfields with leading zeros, you must
omit those zeros when entering the address in your browser. For example, IP
address 128.092.050.004 must be entered as 128.92.50.4.
The DTV735 Control and Status screen will appear. You may select either the
Stream Information, Configuration, or Q&A/Help pages at any time by click-
ing on their respective tabs at the top of the screen.

screen to select the included programs for output, assign new program numbers
if desired, and select the audio to be included in each program’s output. Finally,
select the Stream Info screen to verify the input and output data processed.
Control and
Status Page
The Control side of this screen gives the serial number of the DTV735 unit and
the version number of the application software installed in the unit. The ASI
Output box allows the user to set the output data rate to either 26.97 Mbps or
38.81 Mbps. The IRT Mode box allows the user to enable or disable functions
needed for use in systems with the Motorola IRT product. This is normally set
to OFF. (Refer to IRT Mode on page 34 for more details.)
The Status side provides the unit input and output signal status. The ASI Input
part of Status indicates the presence or lack of an ASI input signal on ASI
Input 1. The Errored Secs indicates the number of seconds in which errors
occurred since the last time the error counter was cleared. ASI/DHEI Output
lists the output stream’s data transport rate as well as the output lock status.
(The QAM modulator associated with the data rate is shown after the data rate,
64 QAM for 26.97 Mbps or 256 QAM for 38.81 Mbps.) Utilization indicates
the percentage of the output Transport Stream’s data rate that is occupied with
actual data (not null packets). This indicator may be used to determine whether
additional programs may be enabled for output.

Configuration
Page
The Configuration screen shown below allows the selection of programs to be
included in the output. In the example shown, programs 1 through 7 have been
selected by placing a check in the boxes next to the input program number.
Program reassignments have been selected by placing the new output numbers
in the corresponding Prog. Output boxes. For example, Input Program 1 is
mapped to Output Program 7, Input Program 2 to Output Program 17, etc. The
Audio selection boxes allow MPEG audio, AC-3 audio, or both to be selected
for output on each program. You should ensure that the selected audio format is
available on the input program. If you select MPEG only and the input has AC-
3 only, you will receive video but no audio for that program. If in doubt, select
both.

Stream
Information
Page
The Stream Info screen shown below allows additional control and monitoring
of the input and output streams. The ASI 1 Input side shows all the programs
present in the ASI input. The number in parentheses after the program number
is the PID number (in hexadecimal form) of that program’s PMT. All streams
included in the program are listed below the program number with their PID
locations indicated in parentheses (in hexadecimal form). For example, in the
screen below, Program 3 has its PMT located in PID 0x3a and its video is
located in PID 0x0130 with audio located in PIDs 0x0131 and 0x0132. Check
boxes allow you to select the program streams that you wish to include in the
output. Click the box to the left of a program to check that program and add it
to the output and then click the Update Selected Programs bar at the bottom of
the screen. Click the Uncheck All hyperlink if you wish to remove checks from
all input check boxes.
Program numbers may be changed by entering the desired values in the pro-
gram number boxes before clicking on the Update Selected Programs box. Pro-
gram numbers must be unique. If you attempt to assign the same program num-
ber to more than one program, an error message will appear and no change will
be made.
NOTE: Program numbers are unique. Do not attempt to assign two input
programs to the same output program number.

3.3 DTV735 Controls and Indicators
There are three major parts of your DTV735’s front-panel controls and indica-
tors: the liquid-crystal display (LCD), the six push buttons, and the eight LED
indicators. Essentially all control available through the terminal is also avail-
able via the front panel (shown below in Figure 3.1).
Figure 3.1 DTV735 Front Panel
Liquid-
crystal
Display(LCD)
The DTV735’s 2-line by 20-character LCD indicates unit status and prompts
for and reflects user input. Here, you will see your DTV735’s "home screen"
which shows the Transport Stream ID (TSID) and the output data rate. Infor-
mation in the bottom row alternates between showing the number of errored
seconds since signal acquisition (or since error reset) and the occupied band-
width of the output data stream. No matter which front panel screen is cur-
rently shown, holding in the ESC button returns the display to the home
screen. From this home screen, press the ENT button to display the unit’s serial
number and the version number of the application software. Using the adjacent
push buttons, you can navigate the DTV735’s various screens and edit input
fields (see section 3.4 Front-panel Operation on page 26).
The default front panel screen is this "home screen". No matter where a user
may be in the screen hierarchy, if no front-panel key press is made for more
than five minutes, then the screen reverts to the “home screen”.

Software
Code
Structure
The DTV735 Processor contains the following unit software: A boot loader
and one version of operating application software. Before power-up, these
components are stored in non-volatile memory. The boot loader resides in a
portion of the memory that may only be written at the factory while the appli-
cation is stored in a portion of memory that can be over-written with down-
loads of new software. The boot code has the responsibility of deciding if the
resident application software image should be allowed to execute.

Initialization
Sequence
At power up, the boot loader software executes first. It performs a test of RAM
and then relocates itself for further execution from there. During boot-up, the
following screens appear in sequence on the LCD:
Following normal boot-up, the "home" screen will appear as described in sec-
tion 3.4 Front-panel Operation on page 26 and the LEDs reflect the actual
state of the unit.
Initialization
Failure
When in Initialization Failure mode, the unit is essentially dead. There is no
ASI output, the alarm relay is de-energized (alarm state), the alarm LED is ON,
and the unit does not attempt acquisition of input streams. Call Wegener Cus-
tomer Service.
3.6 Transport Stream Processing
Refer to ISO 13818-1 for supporting details on the structure of MPEG Trans-
port Streams.
Input to
Output
Processing
The basic DTV735 has an ASI input and two duplicate ASI outputs. The unit
processes the input, selects programs based on user input, and provides an out-
put signal on the DHEI and ASI outputs. The processing includes program
number changes as selected. Based on user selection, certain programs may be
selected and then passed to the ASI output with time stamping updated.
PSIP
Structure and
Program
Selection
Within the transport stream there are PIDs carrying tabular information on that
stream. The PAT describes all the programs available. The program number
identifies each program in the transport stream. When a source of data is
acquired, the stream is passed to the internal transport demultiplexer. This cir-
cuit then extracts the PAT and PMT information and provides this information
to the user via the Stream Info and Configuration pages of the web interface.
The user may then select programs to be included in the ASI output as
described in section 3.2 Ethernet/Web Browser Control.

IRT Mode With systems using the Motorola IRT product, certain additional elements
must be included in the output transport stream. In such systems, be sure to
enable the DTV 735’s IRT Mode by selecting IRT Mode ON from the web
browser interface or front panel (see Control and Status Page on page 19).
When the IRT Mode is on, the DTV735 performs the actions listed here.
•A CAT (Conditional Access Table) PID (0x0001) is included and a CA
system descriptor is added in this packet pointing to a reserved location
(PID 0x0ff9) for the EMM (Encryption Management Message).
•For each program in the stream, a CA descriptor pointing to itself is added
in the PMT. This is a null ECM (Encryption Control Message).
•To the PAT, Program 0 (NIT) is added, pointing to PID 0x0ffe which
carries the STT (System Time Table) clock information.
•The NIT (Network Information Table) must also be present in the
transport stream. This PID (0x0ffe) is created at the uplink and is passed
through.
3.7 Alarm System
The alarm and warning system is intended to provide indications to local user
of a critical failure or imminent failure. See Table 6: LED Indicator Descrip-
tions on page 25 for actual indications.
Alarm
Conditions
Generally, if the unit is unable (or presumed to be unable) to present output
from a selected transport stream, then that is an alarm state. The following list
defines all alarms during normal operation (also see Initialization Failure on
page 33).
1. ASI Input Unlocked – A valid ASI stream is not present on ASI Input 1.
2. Unit oversubscribed – The combined data rate of the input programs
selected exceeds the output data rate selected.
3. PAT missing – The Transport Steam on the input does not have a PAT
present (should be located in PID 0x01.
4. PMT missing – The Transport Steam on the input does not have a PMT
present (should be located in PIDs as shown in the PAT).

Chapter 4 Maintenance and Troubleshooting
4.1 Maintenance
Maintenance of the DTV735 is limited to keeping the chassis clean and ensur-
ing 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 DTV735 incorporates security labels over some of the screws. There are
no user-serviceable components within the DTV735. Tampering with the secu-
rity labels or opening the unit will void your warranty. If you have any ques-
tions, contact Wegener’s Customer Service Department at the address or
numbers listed under Customer Service.
4.2 General Troubleshooting
This section is not an intended as an exhaustive list of all possible situations.
Please contact us as directed in Chapter 5 Customer Service on page 39, with
any problems you cannot resolve independently.
If you are experiencing any difficulties, first check the LCD and LED indica-
tors on the DTV735 to determine if any warnings or alarms are active. See
Table 6: LED Indicator Descriptions on page 25 for descriptions of LED
states. If operating over the Ethernet interface, check the Control and Status tab
on your browser for Warning messages.
No functions
at all
If the unit is not functioning at all and neither the LCD nor any LEDs are
active, there may be a loss of ac power. 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.

Input
Unlocked
Video is lost when the incoming signal is lost. When the ASI IN LOCK LED is
inactive or unlit (shown below), the ASI transport stream sync has been lost.
The WARNING LED will light if both ASI input (1 or 2) and RF input are
selected and RF CARRIER LOCK remains. Check ASI source and input con-
nection.
DTV 735 User’s Manual
wegener.com 37 800021-01 Rev. B
ALARM:
Unit Over-
subscribed
An oversubscription alarm means that the total rate of the selected ASI inputs
is greater than the selected output rate. A corrupt signal is output from the
DTV735. Oversubscription results in errors in the video output. On the front
panel, this is indicated by a lit ALARM LED and an unlit ASI OUT LOCK
LED (shown below). Solve the problem by reducing the number of input pro-
grams to fit the combined input data rate within the selected output data rate.
ALARM:
PAT or PMT
Missing
Video is lost when the incoming signal is missing either the PAT or PMT.
When the ALARM LED is lit and both the ASI 1 LOCK and the ASI OUT
LOCK LEDs are lit then the transport stream does not have sufficient PSI
information included. Check with the service provider to insure that the source
is correct.
4.4 Trouble with Browser Interface
If the unit appears to be functioning normally with no alarm or warning condi-
tions, but you cannot use the web browser interface, first check the LED on the
rear panel next to the Ethernet connector. It will illuminate and blink as LAN
data are detected. If this LED is off check the cabling to the LAN. If the LED
remains off after verifying the LAN connection, contact Customer Service. If
the Ethernet LED is illuminated, check that you are using the correct IP
address. (See “Ethernet/Web Browser Control” on page 17.)
If the address is correct, but the interface still does not function, check your
computer’s IP settings and consult your network administrator for additional
help.
