Connecting the Line
The ASMi-31 line connector is a terminal block/RJ-45 connector. Connect
the transmission line (twisted pair) to the two clips marked LINE and the
cable shield to the clip marked GND (optional). High rate data
communication twisted pair cable is highly recommended in order to
prevent crosstalk.
Before connecting the cables, make sure that the equipment is earthed by
its power cable.

Caution

Insert the GND lead first.
