8. Pull the I/O or audio cable through the casing and cable gland.
9. Once connected, work backwards from step 6 to re-assemble
the parts.
Connectors
Audio in - 3.5mm input for a mono microphone, or a line-in mono
signal (left channel is used from a stereo signal).
Audio out - Audio output (line level) that can be connected to a
public address (PA) system or an active speaker with a built-in
amplifier. A pair of headphones can also be attached. A stereo connector must be used for the audio
out.
I/O terminal connector - Used in applications for e.g. 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, glass break detectors, etc. When a
signal is received the state changes and the input becomes active (shown under Event Con-
figuration > Port Status).

Can be used to power auxiliary equipment.
Note that the AXIS 215 PTZ-E itself cannot
be powered via the I/O terminal connector.
Connect to GND to activate, or leave float-
ing (or unconnected) to deactivate.
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 pro-
tection against voltage transients.
