Installation
The modem should be
connected in the following
way:
Power connection is made
through screw-block at bottom
right corner.
For 115V AC or 230V AC it is
a 3-pole connector, and for 12-
36 or 36-55V DC a 2-pole
connector
Computers or other equipment
are connected through an
RS-232 connection .
This connection can be made
either to the 25-pole D-sub or
the 9-pole screw connector.
Do not use ribbon cable for
RS-232 connections.
