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