AXIS 210/211 - 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 doorbell. If the doorbell 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
4 Transistor Output With a maximum load of 100mA and a maximum voltage of 24V DC, this output
has an open-collector NPN transistor with the emitter connected to pin 1 (GND).
If used with an external relay, a diode must be connected in parallel with the load,
for protection against voltage transients.
3 Digital Input Connect to GND to activate, or leave floating (or unconnected) to deactivate.
2 Auxiliary DC Power Input 7-20 VDC/min 7W. Electrically connected in parallel with the PS-K power
connector, this pin provides an auxiliary connector for mains power to the unit. If
the unit is powered via this pin, a fuse should be used (rating: 1A Slow).
This pin can also be used to power auxiliary equipment, max 100mA, but note that
this is not
possible when the AXIS 211 is powered by PoE.
