39 AXIS 207MW - The I/O Terminal Connector
The I/O Terminal Connector
Used in applications for e.g. motion detection, event triggering, time lapse recording, alarm
notifications, etc., the I/O terminal connector provides the interface to:
• 1 transistor output - For connecting external devices such as relays and LED:s.
Connected devices can be activated by Output buttons on the Live View page or
by an Event Type. The output will show as active (in Event Configuration > Port
Status) if the alarm device is activated.
• 1 digital input - An alarm input for connecting devices that can toggle between
an open and closed circuit, for example: PIRs, door/window contacts, glass break
detectors, etc. When a signal is received the state changes and the input becomes
active (shown under Event Configuration > Port Status).
• Auxiliary power and GND
Transistor
Output Pin 4 Uses 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. Max load = 100mA
Max voltage = 24V DC
(to the transistor)
Digital
Input Pin 3 Connect to GND to activate, or leave floating
(or unconnected) to deactivate. Must not be exposed to
voltages greater than
10V DC
GND Pin 1 Ground
Auxiliary
DC Power
Input Pin 2 Electrically connected in parallel with the con-
nector for the PS-H power supply, this pin pro-
vides an auxiliary connector for mains power
to the unit.
This pin can also be used to power auxiliary
equipment, with a maximum current of 50mA.
Voltage = 4.9-5.1V DC
Min power: 4.0W
The I/O terminal pins are numbered left to right, as shown below.

Connect input/output devices to the camera as follows:
1. Attach the cables for the device securely to the supplied green connector block.
2. Once the cables are connected, push the connector block into the terminal
connector (also green) on the camera.
