Re‐Flashing Your CDM‐570A/570AL Satellite Modem
I.
Introduction: Firmware Files, Naming, Versions, and Formats
1) MAKE SURE TO OPERATE THE CDM‐570A/L WITH ITS LATEST AVAILABLE FIRMWARE.
2) ETHERNET IP FUNCTIONALITY IS AVAILABLE ONLY WHEN THE CDM‐570A/L IS
EQUIPPED WITH THE OPTIONAL IP PACKET PROCESSOR.
The CDM‐570A/L Satellite Modem is factory‐shipped with its latest version of operating firmware. If you
need to update the modem firmware, you may download the update from the Comtech EF Data Web
site (www.comtechefdata.com). You may also receive the firmware update archive file via e‐mail from
Comtech EF Data Product Support.
You may perform the firmware update, without opening the CDM‐570A/L, remotely over satellite (when
the unit is equipped with the optional IP Packet Processor), or by directly connecting a user‐supplied
Microsoft Windows‐based PC to the CDM‐570A/L 'M&C 100' 10/100 Ethernet port (for units without the
optional IP Packet Processor) or the 'Traffic 100' 10/100 Ethernet port (for units equipped with the
optional IP Packet Processor).
Do these steps:
Download the firmware update archive file via the Internet, or acquire the file from Comtech EF
Data Product Support, and transfer the files to the User PC.
Use Windows Command‐line to transfer, via File Transfer Protocol (FTP), the extracted firmware
files from the User PC to the CDM‐570A/L standby firmware image.
Use the CDM‐570A/L front panel or the CDM‐570A HTTP Interface to configure the modem to
operate using the updated firmware image.
To verify the correct firmware number, see Step 1 in the next section of this guide. The firmware
download files are available from Comtech EF Data in two archive file formats: *.exe (self‐extracting)
and *.zip (compressed). Some firewalls will not allow downloading of *.exe files; in this case, download
the *.zip file instead. If applicable, one version prior to the current release is also available for
download.
For additional help with "zipped" file types, refer to the help files provided with the "PKZIP
for Windows", "WinZip", or "ZipCentral" file archiving programs. Comtech EF Data does not
support "PKZIP for DOS" due to file naming conventions.
