Fiber Optic Ethernet Media Converter
The fiber optic media converter is designed to transmit 10/100 Mbps Ethernet signals over
fiber optic cable using 10/100 Mbps Small Form-factor Pluggable (SFP) modules. The SFP
modules are available as multi-mode fiber (MMF) or single-mode fiber (SMF) models with a
single SC connector or dual-fiber with an LC connector. Refer to the VG4-SFPSCKT Fiber Optic
Media Converter Installation Guide.

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 ? terminal resistor.
The AutoDome has a 100 ? termination resistor between the Biphase C+ and C- terminals.
CAUTION!
The Biphase shield must be connected to the head end only.
