Chapter 4. UPDATING FIRMWARE
4.1
Updating Firmware via Internet
TO ENSURE OPTIMAL PERFORMANCE, IT IS IMPORTANT TO OPERATE THE CDM-625
WITH ITS LATEST AVAILABLE FIRMWARE.
The CDM-625 Advanced Satellite Modem is factory-shipped with its latest version of operating
firmware. If a firmware update is needed, once Ethernet connectivity has been established with
the unit, the update can be downloaded from the Comtech EF Data Web site
(www.comtechefdata.com), or obtained through Comtech EF Data Customer Support via e-mail
or on CD by standard mail delivery.
The CDM-625 Firmware Update process is as follows:
•
Perform the update without opening the CDM-625 by connecting the rear panel serial
"Remote Control" port or "10/100 Ethernet" port to a serial or 10/100 BaseT Ethernet port
of the user PC.
•
Download the firmware update via the Internet to the user PC.
•
Transfer the firmware update, via File Transfer Protocol (FTP), from the user PC to the
CDM-625.
4.2
About Firmware Files, Naming, Versions, and Archive Formats
Comtech EF Data's Web site catalogues its firmware update
files by product type (e.g., modem, converter, etc.) and
specific model/optional configuration. The hyperlinks appear
as per the example to the right. This example depicts the
F0020534*_V### base modem bulk firmware download
hyperlink (where '###' indicates the firmware version
number, and '*' denotes the revision letter of that version).
In addition to this base modem bulk firmware archive file, downloads are available for the
CDM-625's optional IP Packet Processor Module, available with or without AES Encryption. This
module requires separate firmware update.
