1.4.3 Connecting the Audio, Sensor and Relay device
The Sensor, Alarm, and audio port enable you to connect 4 sensor inputs, 1 relay outputs, 4 audio in
devices and 1 audio out device. Just connect the external sensor, relay, and audio in/out device pin
directly to the pinhole. The RS485 port can be used for PTZ camera connection.
Check the table below and locate which pinhole is assigned to audio in/out, sensor input, and relay
output.

The RS232 port is not supported at this version.
The signal from the sensor (i.e., infrared sensors, smoke detectors, proximity sensors, door sensors,
etc.) is being transmitted to the unit and this triggers the system to respond and send signal to relay
device (i.e., alarm, telephone etc).
