Ring Operation With the CP-102UF board, your PC can be included as one node of a fiber ring formed using Moxa's own TCF-142 serial-to-fiber converter. Since each TCF-142 has two fiber ports and one serial port, PCs that are part of the ring will be able to communicate with serial devices connected to the ring. Once the ring has been set up, simply use the DIP switches to configure the CP-102UF to "Ring mode." When one node transmits a signal, the signal travels around the ring until it returns back to the transmitting unit, which then blocks the signal. The CP-102UF can be used to set up fiber rings that are up to 100 km in total length.
