Functional description MD-62H
MD-64H is developed for RS-232/V.24 point to point or multidrop (with LD-63H)
communication via fibre optic cables.
The H-version is developed for data and status transmission in a multidrop network.
Transmission rates up to 115.2 kbit/s and transmission distances up to 25 km is possible.
The MD-62H consists of one F/O channel with separate transmitter and receiver,
Tx and Rx. On the front of the unit there are also three LED’s indicating the data
transmission on the channel. The fibre optical cable is completely immune to external
interference, which makes it ideal for harsh environments.
