COMNET FVT240D8S1 overview

  • 1Description

The 24-Channel Digital Video Transmitter & 8-Channel Bidirectional Data Transceiver from ComNet utilizes 10-bit digital encoding and decoding to provide high-quality video transmission that meets the requirements of EIA RS-250C for short-haul video transmission. This environmentally-hardened unit transmits 24 independent video channels and eight bidirectional data channels over one optical fiber for use in unconditioned roadside or out-of-plant installations. It is completely transparent to and universally compatible with any NTSC, PAL, or SECAM CCTV camera systems, while data channels can be set independently for RS-232, RS-422, and 2- or 4-wire RS-485, Sensornet, bi-phase, and Manchester. Plug-and-play design ensures ease of installation and no electrical or optical adjustments are ever required. Bi-color (red/green) LED indicators are provided for rapidly ascertaining equipment operating status.
