Four-Channel Digital Video with One to Four-Channel Bi-Directional Data, Contact Closure and Audio Transmitters and Receivers DESCRIPTION The
740D-XXX
VT/VR(S)
Series
multiplexer
simultaneously transmits four channels of real-time 10-bit digital video and one to four channels of bi-directional data, contact closure or audio both directions over one multimode or single-mode fiber optic cable. The module is universally compatible with major CCTV and Access Control Manufactures
and
supports
bi-directional
transmission of RS-232, RS-422, or RS-485 data interfaces and all major data protocols. The modules incorporate Power, Carrier Detect, Data Transmit and Data Receive status indicating LED’s for each individual channel for monitoring proper system operation. The modules are available in either stand-alone or rack mount version.
FEATURES Optical automatic (OAGC).
A 740D-XXX VT/VR(S) pair transports four
channels of high quality composite video in one direction and one to four channels of data, contact closure or audio in both directions over one optical fiber.
Circuit protector. Hot-Swappable Rack Modules. P/T/Z Control Formats (Data Interface): Duplex
switch-selectable Manchester PTZ.
Exceeds RS250C Short Haul Specifications for
SNR, Differential Phase, and Differential Gain. Video channel: 8 MHz bandwidth; compatible
with NTSC, PAL, SECAM.
RS232,
RS422,
RS485
or
600 Ohms Audio Input Impedance. Eliminate EMI, RFI and ground loop.
