• 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-760 firmware download hyperlink appears as
F0020627x_Vyyy, where ‘x’ denotes the revision letter, and “yyy”
represents the firmware version (e.g., V141 = Version 1.4.1).
The naming and file format of the firmware archive files for Firmware
Versions 1.4.1 and later differs from the naming and file format of the
firmware files provided for Firmware Version 1.3.1 and earlier! See
Appendix A. OBSOLETE FIRMWARE FTP UPDATE PROCEDURES for
instructions on updating CDM-760 modems running FW Vers. 1.1.1
through 1.3.1.
• About File Archive Formats – Comtech EF Data provides its downloadable
files in two compressed archive formats: *.exe (self-extracting) and *.zip
(compressed).
Some firewalls do not allow the download of self-extracting *.exe files.
Download the *.zip file instead, and extract the firmware files from the
archive download with a user-supplied file archiver and compression
utility program such as PKZIP for Windows, WinZip, or ZipCentral. (PKZIP
for DOS is not supported due to file naming conventions.) Comtech EF
