CiM-550 IP Enabled Satellite Modem

Introduction

CD/CIM550.IOM

1.3.2SOFTWARE

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.

1.3.3VERIFICATION

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.

1.3.4DATA INTERFACES

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:

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

1.3.5CDM-550 EMULATION MODE

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.
