AXIS 207 - 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, etc.
• Input - for connecting e.g. a pushbutton. If the pushbutton 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.
Function Pin Description Pinouts
Transistor
Output
4 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 the GND pin. If
used with an external relay, a diode must be
connected in parallel with the load, for pro
-
tection against voltage transients.
The I/O terminal pins on the
AXIS 207 are numbered as
shown below.

Digital Input 3 Connect to GND to activate, or leave float-
ing (or unconnected) to deactivate.
GND 2
Auxiliary DC
Power Input
1 5VDC/min 2.5W. Electrically connected in
parallel with the connector for the PS-L
power adapter, this pin provides an auxiliary
connector for mains power to the unit. This
pin can also be used to power auxiliary
equipment, max 50mA.
