MiniBus™ Digital Databus System Operation The MiniBus is a bi-directional, multi-transmitter digital data network, linking switches to motors, lighting systems and other loads. It allows components to 'talk' to each other, exchanging a continuous stream of information. It's a systems solution to the ever-increasing complexities of vehicle wiring. Diagram - heavy duty vehicles Diagram - boats How the system functions 1. A bank of digital switches feeds 'control commands' to the SIM 2. The SIM communicates these control commands to the PDM 3. The PDM receives this information and directs it to the appropriate output load. The MiniBus continually monitors the system to verify that the load equipment is working correctly. 4. The data are fed back to the switches that indicate the system status via LEDs in the DSRocker switches. Typically a continuous light = system operating, flashing light = fault mode. Fault modes
