AXIS P1311 - Unit connectors
I/O terminal connector - Used in applications for e.g. motion detection, event triggering,
time lapse recording and alarm notifications. In addition to an auxiliary power and a GND
pin, it provides the interface to:
• 1 transistor output - For connecting external devices such as
relays and LEDs. Con-
nected devices can be activated by the VAPIX® Application Programming Interface,
output buttons on the Live View page or by an Event Type. The output will show as
active (shown under Events > Port Status) if the alarm device is activated.
• 1 digital input - An alarm input for connect
ing 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 Events > Port
Status).
The following connection diagram gives an example of how to connect an auxiliary device to the AXIS P1311.
Function Pin Notes Specifications
GND 1 Ground
3.3V DC Power 2 Can be used to power auxiliary equipment.
Note: Th
is pin can only be used as power out.
Max load = 50 mA
Digital Input 3 Connect to GND to activate, or leav
e floating (unconnected) to
deactivate.
Min. input = -40 V DC
Max. input= +40 V DC
Digital Output 4 Uses an open-drain NFET transistor with
the source connected to
GND. If used with an external relay, a diode must be connected in
parallel with the load, for protection against voltage transients.
Max. load =100 mA
Max. voltage = + 40 V DC
