In a daisy chain configuration, where multiple domes are
connected in series, the 100 Ω resistor must be removed from
all but the last dome. You can daisy chain a maximum of four (4)
AutoDomes.

3.4.2 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. This control option is applicable to the VG5 600 Series
only.

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.
