This environmentally hardened unit is suitable for use in unconditioned roadside or out-of-plant installations. The FVR412M1 Receiver 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 receiver 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 receiver can be directly mounted in a COMNET rack or mounted stand-alone without the requirement of any additional parts or power supplies. Note: A transmitter (FVR412M1, available separately) is required at the transmitting end. - Receives 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
