Many Comtech EF Data modems use "flash memory" internally, eliminating the need for
physically replacing firmware. The advantages of using flash are many, but perhaps the greatest
benefit is realized by not having to disassemble the modems to replace an integrated circuit. New
firmware can simply be uploaded to the units from an external PC. The CDM-IP family of
modems have base modem firmware (M&C) and CDM-IP module firmware.

IMPORTANT

Performing a base modem M&C flash upgrade erases the non-volatile RAM, which is
where the modem's configuration is stored. Users must re-enter the desired
configuration parameters.

Note: While the M&C and CDM-IP module firmware downloads are independent processes, the modem
may require the latest firmware releases for both the M&C and CDM-IP module for proper functionality.
Flash updating firmware is a simple process.Users can obtain upgrades by any of these methods:
Download from the Comtech EF Data website (

http://www.comtechefdata.com

)

Download from the Comtech EF data FTP Site (ftp://ftp.comtechefdata.com)

Request shipment on diskettes or CD-ROM.

M&C upgrade can be performed without opening the unit, by connecting the modem to the serial
port of a computer and executing a flash uploader software program. The cable to connect the PC
to the modem is the same as is used for normal EIA-232 remote control, and comprises three
wires connected between two 9-pin "D" type female connectors. Ensure this cable is connected
and working properly before proceeding with an M&C or BULK firmware flash upgrade.

CDM-IP module firmware is upgraded by using an FTP utility to transfer flash files to the
modem. The cable to connect the PC to the modem is a standard 8 pin Category 5 Ethernet cable.
An Ethernet switch, hub or crossover cable is required to facilitate proper connectivity. Ensure
connection is working properly before proceeding with CDM-IP module firmware flash upgrade.


IMPORTANT

The Remote Control port EIA-232 lines used for Flash upgrading are also connected to the
Primary 25-pin data connector (P3B), and are used when 1:N Redundancy Switch is
connected. Please ensure that NOTHING is connected to P3B pins 4, 21 and 22; if these pins
are used, the EIA-232 remote control port will not function, and Flash upgrading will be
impossible.
