The Serial Data Fiber Link Card system transports two active channels of copper serial data over fiber optic cable, allowing for both RS-232 and RS-485/422 to be used at the same time. Fiber optics not only provide long distance communication up to 74 mi. (120km), but also provide immunity to EMI/RFI and transient surges. This is ideal for extending serial data communications over long distances, or near large electrical equipment where resistance to EMI is desired.
The system supports serial data rates from 50 bps to 921.6Kbps, and has an auto-sensing feature that eliminates the need to manually set serial data rates. The included Pull High / Pull Low rotary dials allows for fast and easy biasing adjustment. Each Fiber Link Card requires 24-48VDC and has a comprehensive set of LEDs on the front panel that indicate power status, fiber status, and activity for RS-232 and RS-485/422 channels.
