About Firmware Numbers, File Versions, and
Formats: Comtech EF Data's Web site catalogues its
flashable firmware upgrade files by product type (e.g.,
modem, converter, etc.) and specific model/optional
configuration. The hyperlinks appear as per the example
to the right. For the CDM-840, the firmware download
hyperlink appears as F0000408X_V###, where 'X'
denotes the revision letter, and ### represents the
firmware version.
The current version firmware release is provided. If applicable, one version prior to the current
release is also available. Be sure to identify and download the desired version.
The downloadable files are stored in two formats: *.exe (self-extracting) and *.zip
(compressed). Some firewalls will not allow the downloading of *.exe files. In this case,
download the *.zip file instead.
For additional help with "zipped" file types, refer to PKZIP for Windows, WinZip, or ZipCentral
help files. PKZIP for DOS is not supported due to file naming conventions.
