I/O Terminal Connector; Power; Led Indicators - Axis Q1755 User Manual

I/O terminal connector

Used in applications for e.g. motion detection, event triggering and alarm notifications. In addition to an
auxiliary power and a GND pin, the AXIS Q1755 has 2 pins that can be configured as either input or output.
These pins provide the interface to:
• 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 out-
put will show as active (shown under Event Configuration > Port Status) if the alarm device is activated.
• Digital input - An alarm input for connecting devices that can toggle between an open and closed circuit, for exam-
ple: 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.)

Notes
Ground
Can be used to power auxiliary equipment.
Note:
This pin can only be used as power out.
Digital input - Connect to GND to activate, or leave float-
ing (or unconnected) to deactivate.
Digital output - 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.
Indication
Steady for connection to a 100 Mbit/s network. Flashes for network activity.
Steady for connection to 10 Mbit/s network. Flashes for network activity.
No network connection.
Steady green for normal operation.
Note: The Status LED can be configured to be unlit during normal operation, or to flash only
when the camera is accessed. To configure, go to Setup > System Options > LED. See the online
help files for more information.
Steady during startup, during reset to factory default or when restoring settings.
Slow flash for failed upgrade.
Normal operation.
Flashes green/amber during firmware upgrade.
