Axis Communications 232D, 231D user manual Connection Module Pinout

AXIS 231D/232D - Connection Module 45

Connection Module

This section describes the pinout provided by the Connection module consisting of:

•4 transistor outputs

•4 digital inputs

•power and GND (ground)

not used

24V AC Power

4 transistor outputs

4 digital inputs (see table below)

The inputs/outputs are used in applications for, e.g. event triggering, time lapse recording, alarm notification via email, picture storage to FTP locations.

•Input - e.g. a doorbell. If the doorbell is pressed, the state changes, and the input will be active (shown under Event Configuration > Port Status).

•Output - e.g. an alarm device that can be activated from Output buttons from the Live View page or as an action to an Event Type. The output will show as active (under Event Configuration > Port Status if the alarm device is activated.

Digital Input (1-4)- connect to GND to activate or leave floating (unconnected) to deactivate

Transistor Output (1-4)- Max. load 100mA, max. voltage 24V DC. An open-collector NPN transistor with the emitter connected to pin 2 (GND). If used with an external relay, a diode must be connected in parallel with the load for protection against any voltage transients.

1.Loosen the corresponding screw on top of the pin (see the table above to determine which pin to use).

2.Push the cable into the connector and secure it by fastening the screw.
