MAX-1 Motorola Maxtrac Series Radio Cable Kit

The MAX-1 is a simple interface board that plugs into the back of a Motorola Maxtrac radio equipped with a 16 pin auxiliary connector. 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 MAX-1 Cable Kit comes with two MAX-1 boards, connectors, control system cable and 3 conductor wire to build a jumper between the two MAX-1 connectors. This is all you need to interface to either a single Maxtrac (when used in remote base or a simplex configuration) or a pair of Maxtrac radios (when used in a full duplex configuration with one receiver and one transmitter).
Note: This is a KIT, not an assembled product.
