MOUNTING AND CONNECTING THE MASTER STATION
The Pakscan P3F master station provides front access for all the user connections including power
feed and the field loop wires to the Current Loop module (PS720). The host communication uses
screw terminal connections for the serial comms and RJ45 connections for the Ethernet links.
The field wiring for the loop and the master station alarms is taken to screw terminals on plug
in connectors that are fitted from below their appropriate module.
Power wiring is connected using a 3-way plug-in connector with screw terminals in the top of
the master station main circuit board.
Serial comms ports 1 and 2 (RS232 or RS485) connect to an 8-way plug-in connector with
screw terminals on the bottom of the main circuit board.
Ethernet connections use RJ45 connectors on the main circuit board. The service port
connector is intended for connection to a service laptop computer. Host ports 3 and 4 are for
permanent Ethernet connections.

Before fixing the master station in its permanent location, it may be more convenient to set the
comms link switches as discussed in section 3.
