3.3 Configuring CDM-570Ls for 1:1 Redundancy
IMPORTANT
• Firmware Version 1.3.1 (or higher)
For correct operation of the CRS-170A, the CDM-570L modems must have the
following installed:
• Hardware Revision 3
If the modem does not meet this requirement, contact Comtech EF Data. Flash
firmware upgrades are free and may be downloaded from the CEFD Web page.
Hardware revision upgrades must be performed at CEFD.
The User can fully configure, monitor, and control the operation of the CDM-570L from the
modem front panel using the keypad and display, where nested menus displaying all available
options are used and prompt the User to carry out a required action.
Alternately, configuration, monitoring and control of redundant systems is possible via remote
means over an RS-485 multi-drop bus using the Serial console
Command Line Interface, where
data is transmitted in asynchronous serial form using ASCII characters (see Figure 3-1). For
detailed information on either methodology, refer to the CDM-570/570L Installation and
Operation Manual.
