Wiring for Multiple AutoDomes

To wire multiple AutoDomes in a series, or "daisy chaining," you must apply a terminating
resistor to the last dome of the series. The Interface Board is supplied with a 100 ?
terminating resistor located between the Biphase terminals C- and C+ (pins 1 and 2) of the
P105 control connector (see item 5 in Figure 3.10 above). Remove the resistor from all but the
last AutoDome Interface Board. The maximum number of AutoDomes that can be daisy
chained is four (4).If using the RS485 protocol for control, switch the terminating resistor
from the Biphase C+ and C- terminals to the RxD+ and TxD- terminals (pins 4 and 5) of the
P105 control connector for the last dome (see item 6 in Figure 3.10 above).

Connecting Wires to the Pipe Interface Board

The Pipe Interface Board contains all of the connectors for control, data, image, and power
wires. Follow the procedures below to make the proper connections.
WARNING!
Use a 24 VAC Class 2 power supply only.

WARNING!
Do not connect the RJ45 connector unless using UTP video or Ethernet. This connection
causes video distortion.

To AutoDome
Attach a BNC connector to the video coax cable and connect it to its mating connector
J102 on the Pipe Interface Board. If using UTP for video or Ethernet, attach an RJ45
connector plug to the e UTP cable and connect the plug to its mating connector J101 on
the Pipe Interface Board.
