WebOpto-coupled I/O lines are preconfigured to operate as input or output. You can't change the line mode of opto-coupled lines. If your camera has opto-coupled lines, one of them is always a dedicated input line and another a dedicated output line. WebYou often will use an optocoupler to isolate input from output, but you can also use it to protect an input like you want here. How it works: the input current light the internal infrared LED, which causes an output current through the phototransistor. The ratio between input and output current is called CTR, for Current Transfer Ratio.
