This programming set is designed specifically for quick and easy programming of Motorola GP9000 handheld transceiver. The cable communicates directly with a computer through the serial (COM) port, following the RS-232 specifications. This is a RIB-less cable with the built-in interface so that the Motorola RIB is not required. Simply hook it up to your computer. This single programming interface cable completely replaces Motorola RLN4008 Radio Interface Box (RIB) with RKN4035 cable. This cable does not include any manuals or instructions for use. Therefore, it will be assumed that the purchaser is knowledgeable in using the cable for the applications it is designed for. Please note that we supply the hardware only, we don’t supply the programming software.
