Connection Module Pinout
• 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.

Important!
The AXIS 231D+/232D+ is designed for indoor and outdoor use. To use the
camera outdoors, it must be installed in an approved outdoor housing. Please see
www.axis.com for more information on outdoor housings.
Do not use the camera’s dome bubble if it is to be installed in a protective
housing as the use of two dome bubbles will reduce the image quality and cause
image blurring.
