The IFS VT7830-2DRDT video transmitter/data transceiver 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 eight 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, all standard pan-tilt-zoom control signals including RS-232, RS-422, or 2 or 4-wire RS-485 with Tri-state. 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. This module is the rack mount Version.
