This programming set is designed specifically for quick and easy programming of Motorola Triton Marine handheld transceiver. It requires an external 9 – 12 VDC power source, which should be connected to the DC lead connected through the battery case. 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 HLN9214 (RLN4008) Radio Interface Box (RIB) with HKN9857 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.
