Overview Introduction TCF-142 series converters are equipped with a multiple interface circuit that can handle RS-232, RS-422, and RS-485 serial interfaces, as well as multi-mode or single-mode fiber. TCF-142 converters are used to extend serial transmission distance up to 5 km (TCF-142-M, with multi-mode fiber) or up to 40 km (TCF-142-S, with single-mode fiber).
ATTENTION For Fiber Ring Users: To avoid problems when setting up a fiber ring, each TCF-142 unit making up the ring must be powered down and set to “Ring mode.” Next, make sure all cables are connected properly, and then power up all devices connected to the ring. NOTE “Ring Mode”...
