|Connecting a Visonic radio receiver|
This guide shows how to connect a radio receiver from Visonic to BRIX NetAlarm in a simple way. The Visonic receiver works with Visonic's PowerCode compatible wireless alarm devices, including pendants, door magnets, PIR motion detector, flood detectors and many more.
You will need a pair of wire cutters, a soldering iron, a screw driver and an ohm meter (or continuity tester).
Cut the RS-232 cable
One end of the RS-232 cable is going to be connected to the terminal block inside the receiver, so we need to get rid of one of the D-SUB contacts. The one we need to keep is the female connector.
Strip the insulation from the other end of the cable, and use the continuity tester/ohm meter to find which wire that goes to each of the following pins:
DCD - pin 1 on the D-SUB
TxD - pin 3 on the D-SUB
DTR - pin 4 on the D-SUB
Connect the wires
Connect the wires to the terminal block as follows:
DCD to C
DTR to N.O
TxD to N.C
Connect the power supply
You can for example use a DC adapter such as this one. Connect it to the screw terminal + and - 12V inputs.
Power on and program a transmitter
See section 3.4 Learning Transmitter IDs in the manual that was included with the receiver.
Now start up NetAlarm, go to settings,
and enable external alarms. Select the COM port you connected it to,
and you may also want to write another alarm type text here.
