COMNET FVT412M1 Overview

The FVT412M1 4-Channel 10-Bit Digitally Encoded Video Transmitter with 2 Bi-Directional Data Channels and 1 Bi-Directional Contact Closure from COMNET simultaneously transmits 4 channels of video over a single multimode optical fiber utilizing digital encoding and decoding for high-quality video transmission with two channels of bi-directional data and one bi-directional contact closure over one single mode or multimode optical fiber. It meets the requirements of EIA RS-250C for short-haul video transmission. This environmentally hardened unit is suitable for use in unconditioned roadside or out-of-plant installations. The FVT412M1 is completely transparent to and universally compatible with any NTSC, PAL, or SECAM video transmission protocols and supports bi-directional RS232, 422 and 485-2/4W data.

The plug-and-play design of the transmitter ensures ease of installation and eliminates the requirement for electrical or optical adjustments. Bi-color (red/green) LED indicators are provided to indicate the status of the system, video, and data. Also featuring is the ComFit design which ensures that the transmitter can be directly mounted in a COMNET rack or mounted stand-alone without the requirement of any additional parts or power supplies.

A receiver (FVR412M1, available separately) is required at the receiving end.
Transmits digitally encoded video of 4 real-time color video signals and 2 bi-directional data signals on one optical fiber
Supports RS232, RS422, and 2 or 4-wire RS485
One bi-directional contact closure
Compatible with all NTSC, PAL, or SECAM CCTV camera systems
Robust design ensures high reliability in unconditioned out-of-plant environments
Bi-color (red/green) LED status indicators provide rapid indication of critical operating parameters
Hot-swappable rack modules
Interchangeable between stand-alone or rack mount use thanks to the ComFit design
Tested and certified by an independent laboratory for 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
Voltage transient protection on all power and signal input/output lines provides protection from power surges and other voltage transient events
With the COMNET model DINBKT4 adaptor (not included), the transmitter can be DIN-rail mounted
