Controlling the AutoDome via Biphase
(Shielded 2-wire, half-duplex, multi-drop, 5000 ft. cable limit)
Biphase is the standard Bosch protocol used to send Pan/Tilt/Zoom control over 2-wire
shielded twisted pair (STP) terminated with a 100 Ω terminal resistor.
The AutoDome has a 100 Ω termination resistor between the Biphase C+ and C- terminals.
CAUTION!
The Biphase shield must be connected to the head end only.
