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.

I/O terminal connector:
Pin Function Description
1
GND
2
3.3V 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.
