Figure 1-3 shows a block diagram of the unit. The unit performs several key
functions:
• It accepts incoming data from the terrestrial interface and converts it into
appropriate clock and data signals.
• The modulator operates on the data to frame and encode it for
transmission.
• Encoded information is mapped for modulation.
• A modulated carrier is transmitted from the IF interface for use by uplink
equipment for delivery to the satellite.
• A carrier received from the satellite link is acquired and demodulated to
recover symbols and timing.
• Error correction and deframing are performed.
• User data is delivered to the to the data interface.

first turning off the power to the unit
Introduction Revision 12
Transmit (Tx) data is delivered to the data interface where it is converted to
clock and data signals for further processing. Depending upon the type of
interface, clock and data are provided or in other cases the clock is embedded in
the data and clock recovery is performed to generate clock and data signals.
A First-In–First-Out (FIFO) follows the terrestrial interface to facilitate delivery of
the data to the framing card. Data is passed to the Forward Error Correction
(FEC) Encoder where the data is framed and encoded in accordance with the
DVB-S, DVB-DSNG, or DVB-S2 formats.
After encoding, the data is passed to the modulator where the I&Q signals are
mapped to generate the appropriate constellation (QPSK, 8PSK, 16QAM,
16APSK, and 32APSK) and filtered to provide the desired spectral rolloff.
Finally, a carrier is generated by a frequency synthesizer in conjunction with the
I&Q signals to produce a frequency range, as follows:
• CDM-710 (70/140 MHz), 52 to 88 MHz or 104 to 176 MHz IF output
signal at the rear panel connector
• CDM-710L (L-Band), 950 to 2000 MHz output signal at the rear panel
frequency connector
An Rx carrier from the satellite is received by the demodulator and reverses the
process performed by the modulator. The demodulator has an FEC decoder that
corrects errors incurred during transmission to improve the integrity of the data
delivered to the data interface. A synthesizer in the demodulator is programmed
to select the desired carrier from the transponder.
Physically, the CDM-710/L is comprised of several main card assemblies:
• The optional Data Interface Modules may be quickly plugged into or
removed from the rear panel interface slots.
CAUTION
You must first power down the unit in order to install or
remove a data interface module. Any attempt to install or
remove a module without
will result in damage to the data interface.
• The Framer Card receives signals from the data interface card and routes
signals to the FEC Encoder and Modulator. The microcontroller for the
unit also resides on the Framer Card and is the embedded controller for
the entire unit. The microcontrollers handles all of the monitor and
control for unit including the front panel keypad and display, the EIA-232
and EIA-485 2- or 4-wire remote port and the ‘J7 | Ethernet’ Base-T
10/100 M&C port. Interface with the other modules in the unit is
provided by the framer assembly.
• The FEC Encoder card is a plug-in module that resides on the Framer card.
It generates the encoded stream used by the modulator card.
• The Demodulator card also plugs into the Framer card. It maps and
spectrally shapes the I&Q data for delivery to thew IF interface.
• Depending on the ordered configuration, a modulator and/or
demodulator card may be installed.

must remove the demodulator card. Similarly, when you use a
CDM-710/L as an Rx Only unit in 1:1 Redundancy, you must remove the
1:N Redundancy with the CRS-300: The CRS-300 was originally designed for
operation with the CDM-600. It has since been adapted for use with a number of
other modems. It is capable of supporting interfaces up to the point where there
are no more paths left to route traffic; this is the reason why the CRS-300
supports a limited set of the interface combinations supported by the
CDM-710/L.

2.3 Data Rate Ranges
For the Symbol Rate and Data Rate Ranges for DVB-S, DVB-S2 and DVB-DSNG,
there is some roundoff in the last digit of the values as listed. Table 2-6 is for the
Standard FEC frame, and Table 2-7 is for the Short Frame. QPSK 1/4, 1/3, and 2/5
data is provided for reference only. The tables are based on a 188-byte transport
stream packet. When a 204-byte frame size is selected, the data rate increases
by 204/188.
DVB recommends turning the Pilot ON for 8PSK and higher modulation orders,
particularly when phase noise is present. For 8PSK 1/2, 16APSK 2/3 and 3/4, and
32APSK 3/4: To assist carrier recovery, these modes may need Pilot ON for low
C/N operation.

Make sure to operate the Comtech EF Data CDM-710 or CDM-710L
High-Speed Satellite Modem with its latest available firmware.
The CDM-710/L is factory-shipped with the latest version of operating firmware.
If you need to update the firmware, you can apply the update to the modem
without having to remove it from operation. You may directly acquire the
download from Comtech EF Data’s web site (www.comtechefdata.com
receive the archive file by e-mail from Comtech EF Data Product Support.
5.1.1 Firmware Update Procedure Summary
1. Download the firmware update archive file to a user-supplied PC. The user
PC must be Microsoft Windows® compatible.
2. Make sure the User PC is connected to the base modem rear panel ‘J4 |
Ethernet’ 10/100 Base-T Ethernet M&C port. (Do NOT use the CDI-70 ‘J1’
10/100/1000 Base-T Gigabit Ethernet traffic port.)
3. Use Windows Command-line or Command Prompt to transfer, via File
Transfer Protocol (FTP), the extracted firmware files from the User PC to the
modem’s standby firmware image.
4. Use the modem front panel or the CDM-710/L HTTP Interface to configure
the modem to operate using the updated firmware image.
Comtech EF Data’s Web site catalogues its firmware update files by product type
(e.g., modem, converter, etc.) and specific model/optional configuration. For
example, the CDM-710 firmware download hyperlink appears as F12437x_V####
(where ‘####’ indicates the firmware version number, and ‘x’ is the revision
letter of that version).
Comtech EF Data provides its archive download files in two compressed formats
as *.exe (self-extracting) and *.zip (compressed):
• The self-extracting *.exe file does not require use of a third-party utility
program.
• Some firewalls do not allow the download of self-extracting *.exe files.
You must instead download the *.zip file, and extract the firmware files
from the download with a user-supplied third-party file archiver and
compression utility program such as PKZIP for Windows, WinZip,
ZipCentral, etc. (PKZIP for DOS is not supported due to file naming
conventions). Comtech EF Data does not provide this utility program.
For detailed information on handling archived files, read your archive utility
program’s Help documentation.
5.2 Prepare for the Firmware Download
5.2.1 Required User-supplied Items
You will need:
• A Microsoft Windows-based PC, equipped with available serial and
Ethernet ports.
• A 9-pin serial cable and an RJ-45 CAT5 Ethernet cable to connect the User
PC to the modem.
• A terminal emulator program (e.g., Tera Term or HyperTerminal).
• A compatible Web browser (e.g., Internet Explorer).
3. Click New Folder. This can be an icon or a text label, depending on the
Windows OS version.
4. Right-click the New Folder folder name, and then Rename this folder to
“temp” or some other convenient, unused name.
5.2.4.4 Use Windows Command-line or Command Prompt to
Make a Folder
Select Start on the Windows taskbar and then do these steps:
1. Click Run... to open the Run window (or, depending on Windows OS version
prior to Windows 95, click the MS-DOS Prompt icon from the Main Menu).
2. Open a Command-line window:
• For Windows 95 or Windows 98 – type “command”.
• For any Windows OS versions later than Windows 98 – type “cmd” or
“command”.
• Alternately, from Start, select the All Programs > Accessories popup
submenu, and then select Command Prompt:
3. From the c:\> prompt, type either “mkdir temp” or “md temp” (both “mkdir”
and “md” mean “make directory”), and then press Enter.
There will now be a “temp” folder created and available for placement of the
firmware file download.

way update path. Once an update to 4.0.1 (or higher) is completed, it is
no longer possible to revert to earlier versions – if you attempt to
update the firmware to an earlier version, the modem will detect this
and disallow it as a protective measure.
The one-way update effect is necessary because reallocation of internal
memory for additional space has resulted in an incompatibility between
Firmware Ver. 4.0.1 and all earlier versions.
If you are updating your modem from Firmware Version 4.1.1 to 4.1.2 or
later, you may proceed to the Bulk Firmware Update procedure
described in the next chapter section.
Note the following:
•If updating to Firmware Ver. 4.1.1 or later from a firmware version prior
to Firmware Version 4.0.1, you must first update the modem with
Firmware Version 4.0.1 in both images before you can update the modem
to run Firmware Version 4.1.1.
With the modem running pre-FW Ver. 4.1.1 in both images, do these
steps:
1. Update the first image with Firmware Version 4.0.1.
2. Switch images.
3. Reboot the modem.
4. Update the opposite image with Firmware Version 4.0.1.
5. Reboot the modem.
6. Switch images.
7. Reboot the modem once again.
8. Proceed with the Firmware Version 4.1.1 update.
• If you are running FW Ver. 4.1.1 or later and you intend to update your
modem to a firmware version that is earlier than Firmware Version 4.1.1,
do these steps to downgrade:

5.3 Upload the Firmware Files and Update the
Modem
5.3.1 Important Considerations
Before you proceed with the firmware update, make sure that:
• You connect the modem ‘J4 | Ethernet’ M&C port to the user PC as
described in Section 5.2.1.1.
The BASE MODEM firmware MUST be loaded only
10/100 Base-T ‘J4 | Ethernet’ M&C port. Do NOT use the
CDI-70 ‘J1’ 10/100/1000 Base-T Gigabit Ethernet traffic port.
• Your PC is running a terminal emulation program for operation of the
modem Serial or Ethernet Telnet interfaces.
• You have noted your modem Management IP Address.
• Your PC is running a compatible Web browser for operation of the
modem HTTP Interface.
• You download or otherwise have Comtech’s latest firmware files available
on the User PC in an accessible temporary folder.

2) Type all commands without quotes, and press Enter to execute.
Do these steps:
1. Use Windows Command-line to send a ping command. To ping the unit, type
“ping xxx.xxx.xxx.xxx” at the Windows Command-line prompt. The response
should confirm whether the unit is connected and communicating correctly
with the User PC.
2. Use Windows Command-line to transfer the files from the User PC to the
modem via FTP:
a. Type “ftp xxx.xxx.xxx.xxx” to open the FTP session.
b. Type “bin” to set the binary transfer mode.
c. Type “prompt”.
d. Type “hash”.
e. To begin the file transfer, type

complete, this could lead to an incomplete download,
and you must repeat the “put” command (Step 2e).
2) You must make sure to update both images with the same
firmware version for the unit to function properly.
3) The upgrade from an earlier version to 4.x.x is a one-way
update path. Once you complete an update to FW Ver.
4.0.1, it is no longer possible to revert to earlier versions.
If you attempt to update to an earlier firmware version,
the modem will detect and disallow this as a protective
measure. The unit will also disallow an attempt to switch
to an image that contains an earlier version of firmware.
Wait for the file transfer to end. When it has finished, the modem front
panel will display:

5.5 USB Firmware Update Procedure
Use of the front panel USB port for the firmware update process is not
available in this firmware release. Please contact Comtech EF Data
Product Support for this feature’s release schedule.
The CDM-710 and CDM-710L Broadcast Satellite Modems incorporate a number
of optional features. In order to permit a lower initial cost, you may purchase the
unit with only the desired features enabled.
If you wish to upgrade the functionality of a unit at a later date, Comtech EF Data
provides Fully Accessible System Topology (FAST), which permits the purchase
and activation of options through special authorization codes. You may contact
Comtech EF Data Product Support to purchase these unique, register-specific
Fast Access Codes, and then load these codes into the modem using the front
panel keypad or the HTTP (Web Server) Interface (accessible by connecting your
PC Ethernet port to the CDM-710/L ‘J4 | Ethernet’ 10/100 Base-T M&C Ethernet
port).
FAST System Theory: FAST facilitates on-site upgrade of the operating feature
set without removing a unit from the setup. FAST technology allows you to order
a unit precisely tailored for the initial application. When your service
requirements change, you can upgrade the topology of the unit to meet these
requirements within minutes. This accelerated upgrade is possible because of
FAST’s extensive use of the programmable logic devices incorporated into
Comtech EF Data products.
FAST Implementation: Comtech EF Data implements the FAST system in the
modem at the factory. All FAST Features are available through the basic platform
unit at the time of order – FAST allows immediate activation of available options,
