MC Sonar / Encoder driver board (plugs into backpl
The Sonar/Encoder driver board provides the high current 5 vdc power supply required for the Polaroid 6500 sonar unit. This board also provides sonar multiplexing which allows one input to read all three sonar units. The multiplexing reduces the required I/O used for three sonar units to (1) input and (3) outputs. The board also provides power and the biasing resistor network required for the simple pulse encoder optics included with all the MAX mobile robot packages. This board drives up to 3 sonar units, 2 encoder optics and plugs directly into the HC11 MC back plane!
