CDM-1 Motorola CDM Series Radio IO Board

cdm

The CDM-1 board a simple interface board that plugs into the back of a Motorola CDM1250 and CDM1550 series mobile radio using the 20 pin connector on the back of the CDM1250 and CDM1550 radios. This interface connects the Rx and Tx audio signals, COS, COS & PL decode and PTT signals from the radio to a 9 pin D connector with the same pin out as the RCB making interfacing between the radio and the control system very simple. A cable with a male 9 pin D connector on either end with straight through wiring on all 9 pins is all that is required. The CDM-1 Cable Kit comes with two CDM-1 boards, connectors, control system cable and 3 conductor wire to build a jumper between the two CDM-1 connectors. This is all you need to interface to either a single CDM-1250 or CDM-1550 radio (when used in remote base or a simplex configuration) or a pair of CDM series radios (when used in a full duplex configuration with one receiver and one transmitter).
Note: This is a KIT, not an assembled product.
