4 Preparing the Wiring
There are four (4) types of wires required: control, video, power, and alarm. Each section pro-
vides the specifications for the recommended wire.
4.1 Control
The control wire from the head end should use a twisted-shielded pair recommended Belden
8760 or equivalent with a maximum length of 1.2 km (4000 ft).
Biphase (shielded 2-wire, half-duplex, multi-drop, 1.2 km (4000 ft.) cable limit), is the stan-
dard Bosch protocol used to send Pan/Tilt/Zoom control over 2-wire shielded twisted pair
(STP). The AutoDome Easy has an internal 110
Ω termination resistor between the b)
and biphase(-).
The shield connects to the Head End controller and not to theAutoDome Easy.
4.2 Video
The video coax cable should use a shield coverage copper braid 95% and standard copper
center conductor. Recommended cables are RG-59, RG-6/U, or RG-11U.
4.3 Power
The recommended power cable is a 2-conductor, 14-18 gage cable, depending on the dis-
tance. Refer to the wiring distance guide Table 4.1 on page 5.
!
CAUTION! Installation should only be performed by qualified service personnel in accordance
with the National Electrical Code or applicable local codes.
!
CAUTION! The biphase shield must be connected to the head end only.
