The internal software is both powerful and flexible, permitting storage and retrieval of up
to 10 different modem configurations. The modem uses ‘flash memory’ technology
internally, and new firmware can be uploaded to the unit from an external PC. This
simplifies software upgrading, and updates can now be sent via the Internet, E-mail, or on
disk. The upgrade can be performed without opening the unit, by simply connecting the
modem to the serial port of a computer.

ERIFICATION
The unit includes many test modes and loopbacks for rapid verification of the correct
functioning of the unit. Of particular note is the IF loopback, which permits the user to
perform a quick diagnostic test without having to disturb external cabling. During the
loopback, all of the receive configuration parameters are temporarily changed to match
those of the transmit side. When normal operation is again selected, all of the previous
values are restored.

NTERFACES
The CiM-550 includes, as standard, a universal data interface which eliminates the need
to exchange interface cards for different applications. The interfaces offered include:
to exchange interface cards for different applications. The interfaces offered include:
10baseT/100baseT Ethernet (RJ-45 connector)
EIA-422 (EIA530) DCE
V.35 DCE
Synchronous EIA-232 DCE
Asynchronous EIA-232 (at data rates up to 56 kbaud)
X.21 DTE and DCE

ODE
The CiM-550 can be made to operate in CDM-550 emulation mode, where it behaves
exactly like the Comtech EF Data CDM-550 satellite modem. The emulation mode is
selected from the front panel by selecting Configuration/Interface and then selecting
either EIA-422/530, V.35, or EIA-232 as the interface rather than IP. The CiM-550 will
then pass standard serial traffic, like a CDM-550, but will not pass IP traffic. The CiM-
550 can still be accessed via the ethernet port using Telnet, HTTP, or SNMP.
