• 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.
G. Download the archive file to the temporary folder.
• Once the EXE or ZIP hyperlink is selected, the ‘File Download’ window opens and
prompts selection of [Open] or [Save]:
o
Click [Open] to turn over file extraction to the user-supplied utility program. Be
sure to extract the firmware files to the “temp” folder created earlier.
o
Click [Save] to open the ‘Save As’ window. Be sure to select and [Save] the
archive *.exe or *.zip file to the “temp” folder created earlier.
o
Otherwise, click [Cancel] to quit and exit the file download process.
2. Next, extract the firmware files from the archive file.
• (If not already done with File Download > [Open]) Extract the firmware files from the
downloaded *.exe or *.zip archive file with the user-supplied utility program:
o
Double-click on the archive file name, and then follow the prompts provided by the
user-supplied utility program. Extract, at a minimum, two files:
 FW0000###x.bin – the Firmware Bulk image file (where ‘###’ denotes the
CDM-625 or CDM-750 Firmware part number, and ‘x’ denotes the revision
letter), and
