Wiring Examples
The following examples are shown as a guide as to what can be achieved by the I/O features. It is up to the system integrator to
have enough knowledge about the interface to be able to achieve the required results.
Note: NetComm Wireless does not offer any further advice on the external wiring requirements or wiring to particular
sensors, and will not be responsible for any damage to the unit or any other device used in conjunction with it. Using
outputs to control high voltage equipment can be dangerous. The integrator must be a qualified electrician if dealing with
mains voltages controlled by this unit.
Open Collector Output driving a relay
Any output can be configured to control a relay. This is an example where the transistor will supply the ground terminal of the
solenoid. External voltage is supplied to the other side of the solenoid.
Logic level Output
An output can be used with the pull up resistor to provide a logic level output which would be suitable to control an external digital
device.
LED Output
An LED can be controlled by simply providing an open collector ground to an externally powered LED Resistor value and Voltage
will need to suit the LED type used. Alternatively an LED can be powered using 8V2 via 1K resistor. The suitability of the LED will
need to be investigated.
