AXIS 231D - Connection Module
Connection Module
This section describes the pinout provided by the Connection module consisting of:
• 4 transistor outputs
• 4 digital inputs
• power and GND (ground)
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.
Connection Module Pinout
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.

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.
