CRS-500 1:N Redundancy System
Revision 4
Firmware Update 6–2 MN-CRS-500
6.1.2 About Firmware Numbers, File Versions, and 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 CRS-500’s files are provided under
“
Home | Support | Software Downloads | Flash & Software Update Files |Modem
Accessories | CRS-500 .”
Note that firmware is modem-specific. The firmware download hyperlink appears either as:
•
F0000389X_V### (for the CDM-625 or CDM-625A);
•
F0000476X_V### (for the CDM-750 or CDM-760).
Typical for either, ‘X’ is the revision letter, and ‘###’ represents the firmware version number –
e.g., V126 = Version 1.2.6.
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.
