Description LD-63
The LD-63 is a line splitter designed for use in multi-drop fibre optic neworks. The LD-63 allows
the conversion between RS-422/485, RS-232/V.24 and fibre optic. The LD-63 consists of two
F/O channels, each with its separate transmitter and receiver (TX1, TX2, RX1and RX2) On the
front of the unit there are seven LED’s indicating the datatransmission on the channels.
The fibre optic interface is transparent which means that data received on RX1 is retransmit-
ted on TX2 and data received on RX2 on TX1. The LD-63 allows communication on both
RS-422/485 and RS-232/V.24 but data should never be transmitted to both RS-422/485 and
RS-232/V.24 at the same time as it will be oversampled and be impossible to read correctly.
The number of LD-63’s that can be connected in series is limited. See chart on page 11.

Synchronous protocols can be transmitted under certain circumstances.
