AXIS 207/207W - 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 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.

Transistor
Output 4With 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 and AXIS 207W are
numbered as shown below.

Electrically connected in parallel with the
connector for the PS-L/PS-H 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.
