Compatibility Notes:
1. The CDM-625 Open Network Satellite Modem, with its available CDM-600 Emulator Mode,
serves as an operationally transparent replacement unit for the CDM-600/600L Open Network
Satellite Modems.
2. The CiM-25, Comtech EF Data’s low-cost Internet Protocol (IP) Monitor & Control (M&C)
interface for existing CEFD modems, is not compatible for use on modems operating within a
CRS-300 redundancy system. Taking this prohibition of use under further consideration, the
CiM-25 should not, under any circumstances, be connected to the Remote port on the
CRS-300’s CRS-230 Controller card for control of the Switch and modems.
