AXIS 211W - I/O Terminal Connector
37
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
Connection diagram
Function Pin number Notes Specifications
GND 1 Ground
5V DC Power 2 Can be used as an alternative power supply (7-20VDC) or to power
auxiliary equipment +5VDC (100mA).
Max load = 100mA
Digital Input 3 Connect to GND to activate, or leave floating (or unconnected) to
deactivate.
Must not be exposed to voltages greater
than
20VDC
Transistor Output 4 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.
Max load =100mA
Max voltage = 24VDC
