WinCounter Wiring Diagrams

WinCounter requires a sensor or switch connected to the serial port (com port) of your computer. A basic connection only requires a single switch contact and a resistor. Connecting cables and interfaces are available from Software Studio Ltd, You can wire your own connector or have a local electrician/alarm installer etc. wire a cable and sensor for you.

WARNING! Although the connector wiring is very simple, if you chose to wire your own connector or have someone wire it for you Software Studio can take no responsibility for damage caused to your computer by wiring, sensors or switches installed by a third party.

The basic requirement for triggering WinCounter is to switch DSR from DTR to RTS. The simplest way is to connect a switch is to use single switch contact between DSR and RTS and a pull-up resistor between DSR and DTR. The wiring diagrams for this configuration are shown below. It doesn't matter if your sensor contact is normally open or normally closed as you can adjust whether WinCounter triggers from a leading or trailing edge in the software.

WinCounter uses the other connections to determine if a WinCounter cable is connected to the serial port.

We recommend using an opto-coupler to isolate the PC serial port from the sensor.

Wiring for up to 3 sensors on a 9 pin serial port.

If you are not using the additional sensors still connect the pull-up resistors.
