About Firmware Numbers, File Versions, and Formats: The Comtech EF
Data Web site catalogues its firmware update files by product type (e.g.,
router, modem, etc.), the specific model, and optional hardware
configurations.
The CDM‐750 firmware download hyperlink appears as F0000305X_V###,
where 'X' denotes the revision letter, and '###' represents the firmware
version (e.g., V123 = Version 1.2.3).
•
About File Archive Formats: Comtech EF Data provides its downloadable
files in two compressed archive formats: *.exe (self‐extracting) and *.zip
(compressed).
The *.exe file does not require a 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.
Some firewalls do not allow the download of *.exe files. Download the
*.zip file instead, and extract the firmware files from the archive
download with a user‐supplied utility program. For detailed information
on handling archived files, refer to the utility program Help
documentation.
