Functional description LD-63H
LD-63H is developed for RS-232 multidrop communication via fibre-optic cables. The H-version
is developed for data and status transmission in a multidrop network. Transmission rates up to
115,2kbit/s and transmission distances up to 25km is possible.
The LD-63H consists of two F/O channels, each with its separate transmitter and receiver
(TX1, TX2, RX1 and RX2). On the front of the unit there are seven LED’s indicating the data-
transmission 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-63’s that can be connected in series is limited, see chart on page 4.
* Synchronous protocols can be transmitted under certain circumstances.
See ”selection of bits” page 4.
