The ComNet FVT/FVR1031 series video transmitter/ receiver and data transceiver supports simultaneous transmission of short-haul quality 10-bit Digitally Encoded video or bi-directional data over one multimode or single mode optical fiber. The module is universally compatible with major CCTV camera manufacturers and supports RS232, RS422 and 2 or 4-wire RS485 data interfaces, and most major data protocols. The FVT/FVR1031 allows the user to set the data mode through a switch on the unit. Features Supports RS232, RS422 or RS485 (2 or 4-wire) data interfaces Automatic resettable fuses on all power lines Status indicating LEDs provide rapid indication of critical operating parameters. Lifetime Warranty Supports Pelco and Panasonic "UP-THE-COAX" control signals for a distance up to 1500 feet (590 meters). Distances up to 43 mi (69 km) Voltage transient protection on all power and signal input/output lines provides protection from power surges and other voltage transient events. Compatible with NTSC, PAL, or SECAM Video Standards 10-bit digitally encoded short-haul video transmission meets the requirements of the EIA RS-250C standard. Designed to meet full compliance with the environmental requirements (ambient operating temperature, mechanical shock, vibration, humidity with condensation, high-line/low-line voltage conditions, and transient voltage protection) of NEMA TS-1/TS-2 and the Caltrans Specification for Traffic Signal Control Equipment. Standard ComFit models are hot-swappable. ComFit standard form factor is designed for wall, surface, rack, or DIN rail mount installations (using optional card cage or DIN mounting bracket).
