Introduction
The Mxp-631 media converters are equipped with a multiple interface circuit that can handle RS-232 or RS-422/485 serial interfaces and multi-mode or single-mode fiber. Mxp-631 converters are used to extend serial transmission up to 5km (Mxp-631-MM with multi-mode fiber) or up to 40km (Mxp-631-SM with single-mode fiber). The Mxp-631 converters can be configured to convert either RS-232 signals, or RS422/485 signals, but not both at the same time.Automatic Baudrate Detection
The Mxp-631 converters 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 Operation
The Mxp-631 converters can be used to connect serial devices to a fiber ring. To form the ring, connect to the Tx port of one Mxp-631 to the Rx port of a neighbouring converter. Once the ring is set up, simply use the DIP switches to configure the Mxp-631 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 Mxp-631, you can set up fiber rings that have a total circumference of up to 100km.
Automatic Data Direction Control (ADCC®)
ADDC® is a patented hardware data flow solution to handle RS-485 data direction control. ADDC® senses and controls RS-485 data direction automatically, making it unnecessary to use the hand shaking signal.
