VT/VR7200-2DRDT Series
IFS 2-Channel Digitally Encoded Video
and 2 Bi-Directional Data Multiplexer
Overview
The IFS VT/VR7200-2DRDT video transmitter/data
transceiver and video receiver/data transceiver series
utilizes state-of-the-art 8-bit digital encoding and decoding
for high-quality video transmission that exceeds the
requirements of EIA RS-250C for Medium-Haul Video
Transmission. These environmentally hardened units
provide transmission of two independent video channels
and two bi-directional data channels over one single
mode or multimode optical fiber and are ideal for use
in unconditioned roadside or out-of-plant installations.
Completely transparent to and universally compatible
with any NTSC, PAL, or SECAM CCTV camera system. Data
channels can be set independently for RS-232, RS-422 and
2 or 4-wire RS-485 with tri-state support. Plug-and-play
design ensures ease of installation and no electrical or
optical adjustments are ever required. LED indicators are
provided for rapidly ascertaining equipment operating
status, and these units are available in either stand-alone
or rack mount configurations.
