Rs-232 422 485 to optical fiber media convertersthe tcf-142 media converter is equipped with a multiple interface circuit that can handle rs-232 or rs-422 485 serial interfaces and multi-mode or single-mode fiber. Tcf-142 converters are used to extend serial transmission up to 5 km tcf-142-m with multi-mode fiber or up to 40 km tcf-142-s with single-mode fiber . The tcf-142 can be configured to convert either rs-232 signals. Or rs-422 485 signals. But not both at the same time.Automatic baudrate detectionthe tcf-142 can automatically detect the serial baudrate. This is an extremely convenient feature. Even if a device’s baudrate is changed. The signal will still be transmitted through the media converter without any data loss.Ring operationthe tcf-142 can be used to connect serial devices to a fiber ring. To form the ring. Connect the tx port of one tcf-142 to the rx port of a neighboring converter. Once the ring is set up. Simply use the dip switches to configure the tcf-142 converters for 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. With the tcf-142. You can set up fiber rings that have a total circumference of up to 100 km.Automatic data direction control addc addc is a patented hardware data flow solution developed by moxa to handle rs-485 data direction control. Addc senses and controls rs-485 data direction automatically. Making it unnecessary to use the ...
