Controlling the AutoDome via the RS232 Protocol

(3-wire, full-duplex, single-ended, 50 ft. cable limit)
RS232 is a common, single-ended communication protocol used for control. Data
transmission via 3-wires (TDX, RXD, common) is from one transmitter to one receiver at
relatively slow baud rates (up to 57.6 Kbaud) and short distances up to 50 ft.
NOTICE!
After making the wire connections for RS232 operation, reposition the slide switch located on
the CPU Module to the camera head inward and away from the LEDs.
