4.1.1 About Firmware Files, Naming, Versions, and Archive Formats
The SLM-5650B is factory-shipped with the latest version of operating firmware. If a firmware
update is needed, it can be acquired by download from Comtech EF Data's website, as shown in
Section 4.1.2, or from Comtech EF Data Customer Support during normal business hours via e-
mail or on CD by standard mail delivery.
Comtech EF Data's Web site catalogues its firmware update files by product type (e.g., modem,
converter, etc.) and specific model/optional configuration. The hyperlinks appear as per the
example to the right. In this example, the F0021022x_V### Base Modem firmware download
hyperlink is shown, where 'x' denotes the revision letter and ### represents the firmware
version. If applicable, one version prior to the current release is also available for download.
In addition to the download for the Base Modem bulk firmware, downloads are available for the
SLM-5650B's optional Network Processor (NP) module. This module requires a separate
firmware update.
To obtain the firmware update for the TRANSEC Module, contact Network
Product Customer Support.
The firmware download files are available from Comtech EF Data in two archive file 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.
