Description LD-63B
The LD-63B is a line splitter for use in multi-drop fibre optic networks. The LD-63B
allows conversion between RS-422/485 and fibre optic. LD-63B is specially developed for
Manchester coded protocols with transmission rates over 500 kbit/s. The LD-63B
consists of two F/O channels, each with its separate transmitter and receiver (TX1, TX2,
RX1 and RX2). On the front of the units there are seven LED’s indicating the datatrans-
mission on the channels. The fibre optic interface is transparent which means that data
received on RX1 is retransmitted on TX2 and data received on RX2 on TX1.
The number of LD-63B in multidrop is limited. See table of ”Maximum number of units”
on page 15.
