About Firmware Numbers, File Versions, and Formats: The flashable files on the
download server are organized by product prefix; firmware number (verify that the correct
firmware number is known as shown in Step 1); revision letter, if applicable; and release
version.
The base modem bulk firmware for the CDM-750 is FW0000305x_V### (where 'x'
denotes revision letter and '###' 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,
(cont)
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.
Extract the files into the temporary folder on the PC. At least two files should be extracted:

•
FW0000305x.bin, where 'x' denotes the bulk image file revision letter.
•
CDM-750_ReleaseNotes_vXXX.pdf, where 'XXX' denotes the firmware version.
Confirm that the files have been extracted to the specified temporary folder on the PC.

Using Command-line, type "cd c:\temp" to change to the temporary directory created in
Step 2, then use the "dir" command to list the files extracted from the downloaded archive
file.
Connect the external PC to the CDM-750 10/100 Ethernet Management Port via a hub or
6
a switch, or directly to a PC.
Send a "ping" command to the CDM-750 to verify the connection and communication:

First, determine the IP address of the CDM-750 remotely or by using the front panel:
•
Remotely: Use <0/IPA? command;
•
Front panel: Use SELECT: Configuration
menu.
Then, using Command-line to PING: At the prompt, type "ping xxx.xxx.xxx.xxx" (where
'xxx.xxx.xxx.xxx' is the IP address of the CDM-750). The results should confirm whether or
not the CDM-750 is connected and communicating.
