Connecting the Camera
■
External Device Input Terminal
The external device input terminal consists of an IN terminal (IN1 or IN2) and a GND
terminal. Connecting wires to the IN and GND terminals and opening or closing the circuit
notifies the Viewer.
Important
• When connecting sensors and switches, use those that have terminals which are
isolated from internal power and GND.
■
External Device Output Terminals
The external device output terminal consists of an OUT terminal (OUT1 or OUT2) and a
GND terminal. Controls from the viewer can be used to open and close the circuit between
the two terminals. A MOS FET device is used for the output terminal.
