Alarm I/O Wiring Diagram
Connecting to the I/O port box
Connect the Alarm I/O signal to the corresponding port of the rear port box.
• ALARM IN : Used to connect the alarm input signal.
• ALARM OUT : Used to connect the alarm output signal.
• ALARM COM : Common port where the alarm output signal is connected.
• GND : Used for earth-grounding.
• RS-485+ : Communication port for RS-485 receiver (+).
• RS-485- : Communication port for RS-485 receiver (–).
Connecting an external RS-485 device
Connect the camera with an external device using the [RS-485 +, -] ports.
You can control the pan/tilt operations of the camera via RS-485 communications.
The GND connection is recommended for RS-485 communications. If you encounter a communication
failure, connect the GND pin as appropriate to correct the GND level between camera and external device.
