I/O Terminal Connector; Connection Diagram - Axis 211W User Manual

I/O Terminal Connector

The I/O terminal connector is used in applications such as motion detection,
event triggering, time lapse recording and alarm notifications. It provides the
interface to:
• 1 transistor output - For connecting external devices such as relays and
LEDs. Connected devices can be activated by AXIS VAPIX API, output
buttons on the Live View page or by an Event Type. The output will
show as active (shown under 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, and glass break detec-
tors. When a signal is received the state changes and the input becomes active (shown under Event
Configuration > Port Status).
• Auxiliary power and GND

Notes
Ground
Can be used as an alternative power supply (7-20VDC) or to power
auxiliary equipment +5VDC (100mA).
Connect to GND to activate, or leave floating (or unconnected) to
deactivate.
Connects to GND when activated. If used with an external relay, a
diode must be connected in parallel with the load, for protection
against voltage transients.
