AXIS 216FD/FD-V - The I/O Terminal Connector
The I/O Terminal Connector

Pinout and Interface

The 4-pin I/O terminal connector provides the interface to:
• 1 transistor output
• 1 digital input
• auxiliary power and GND
The terminal connector is used in applications for e.g. motion detection, event triggering,
time lapse recording, alarm notification via email, image storage to FTP locations, etc.
•Input - for connecting e.g. a push button. If the push button is pressed, the state
changes and the input becomes active (shown under Event Configuration > Port
Status).
•Output - connects e.g. an alarm device that can be activated by Output buttons
on the Live View page, or by an Event Type. The output will show as active
(Event Configuration > Port Status) if the alarm device is activated.

Pin Function Description
1GND
23.3V DC
Can be used to power auxiliary equipment, max 50mA.
3 Digital Input Connect to GND to activate, or leave floating (or unconnected) to deactivate.
4 Transistor Output With a maximum load of 50mA and a maximum voltage of 24V DC, this out-
put has an open-collector NPN transistor with the emitter connected to the
GND pin. If used with an external relay, a diode must be connected in parallel
with the load, for protection against voltage transients.
