Introduction
The PC Interface module is an accessory Synergy. With this, the system can be connected to a PC. It can also be
used to amplify signals if the communication loop is more than 6500 feet (2000 meters).
NOTE!
The Synergy installation guide (SB3080) should be available when installing the module.
2.
Mechanical installation
The PC Interface module is delivered mounted in a box with a DSUB 9-pin serial cable.
A module in a box is mounted on a wall or other suitable place close to a PC using the four
ø
0.197” (
ø5 mm) holes
in the bottom of the casing. The serial cable included is 10 ft. long (3 meters).
3.
Electrical installation
The module has four connectors
(A)
in two groups. The four connectors are marked
A
,
B
,
+24 V
and
Gnd
. Use
these to connect the module to an existing system. Consult the cable recommendations in the Synergy installation
guide (SB3080)
NOTE!
+24VDC may only be connected to one connector.
At the connector
(B)
you connect the flat cable for RS-232 serial communication with a PC. Communication through
this port is indicated by LED
(C)
.
The LED
(D)
is lit when the system is working properly.
If the module is used as a signal amplifier one communication loop should be connected to one Line and the other
loop to the other Line.
You must set termination and BIAS for BOTH groups using the DIL-switches at (E).
The PCB (Printed Circuit Board) gets its power from the communication loop. The circuit board takes power from
the communication loop.If the module is placed far away from a MPDM it is possible to apply an external power-
supply to
one
of the connectors
(A)
.
NOTE! If only one line is used the other one must be terminated, all switches in the ON position.
