Connecting an external RS-485/RS-232 device
Connect the camera with an external device using the [Tx, Rx, RS-485-, RS-485+] ports.
You can control the pan/tilt operations of the camera via RS-485/RS-232 communications.
The GND connection is recommended for RS-485/RS-232 communications. If you encounter a
communication failure, connect the GND pin as appropriate to correct the GND level between camera and
external device.
To connect the external sensor
Connect one strand of each signal line (2-strand) of the sensors to the [Alarm in 1/2] port,
and connect the other strand to the [GND] port.
J
Be attention not to connect an Alarm in signal higher than 6V.
