GE Security VR7430-2DRDT-SC-R3, VR7430-2DRDT-SC, VR7420-2DRDT-SC Specsheet
VT/VR7400-2DRDT Series
IFS 4-Channel Digitally Encoded Video
and 2 Bi-Directional Data Multiplexer
Overview
The IFS VT/VR7400-2DRDT 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 four independent video channels
and two bi-directional data channels over one 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
