- 1Description
The Dual High-Speed RS485 “A” End Point Data Transceiver from ComNet provides point-to-point or drop-and-repeat transmission of two independent simplex or duplex high-speed RS485 (2W) data signals over one optical fiber. It is transparent to data encoding allowing for broad-range compatibility. A medium-sized surface mount module, this transceiver can be used with single-mode optical fiber and features built-in DIP switch-selectable bias and termination resistors for each data channel. Plug-and-play design ensures ease of installation, requiring no electrical or optical adjustments. Each transceiver incorporates bi-color (red/green) indicating LEDs for monitoring proper system operation, including the location of fiber breaks.
- General
-
- Data rates up to 1 Mbps
- Meets RS485 (2W) specifications
- Tested and certified 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
- Design assures high reliability in unconditioned out-of-plant/roadside environments
- NTCIP compatible
- Built-in fiber link tester allows for the testing of the fiber
- Remote fault indication allows the user to determine when a fiber break or loss of prime operating power has occurred, or a transceiver in the field has failed
- Voltage transient protection on all power and signal input/output lines provides protection from power surges and other voltage transient events
- Wide optical dynamic range without the need for optical attenuators
- Bi-color (red/green) LED status indicators provide rapid indication of critical operating parameters
- Made in the USA
- Applications
-
- Access control systems
- Building automation and environmental control systems
- Computer/data equipment
- Fire and alarm systems
- Traffic signal control equipment
