5.1.2 About Firmware Numbers, File Versions, and
Formats
The Comtech EF Data Web site catalogues its firmware update archive
files by product type (e.g., router, modem, etc.), the specific model, and
optional hardware configurations. The DT-4500 files are provided under
"Home | Support | Software Downloads | Flash & Software Update
Files | Converters | DT-4500 Series & UT-4500 Series Software
Downloads."
The DT-4500 firmware download hyperlink for the Ethernet-ready
current production unit (i.e., Ver6x chassis) is F0000202x_V###.
The DT-4500 firmware download hyperlinks for older, non-Ethernet
units (Ver5x and earlier chassis) are as follows:
• Ver5x Units / 1 kHz Step Size: F1611-1x_v###
• Ver5x Units / 125 kHz Step Size Units: F1610-1x_v###
• Ver4x Units / 1 kHz Step Size Units: F1604-1x_v###
• Ver4x Units / 125 kHz Step Size Units: F1603-1x_v###
Note that 'x' is the firmware revision letter, and '###' represents the
firmware version number (e.g., V123 = Version 1.2.3).
Comtech EF Data provides its archive download files in two compressed
formats – *.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 utility
program's Help documentation.
