Description MD-63B
MD-63B allows point to point communication and conversion between RS-422/485 and
fibre. The modem is developed for Manchester coded protocols with transmission rates
over 500 kbit/s. Transmission distances up to 25 km is possible. The modem consists of
one fibre channel with separate transmitter and receiver. On the front of the unit there
are five LED’s that indicates the data transmission on the channel.
