29DeviceDIConnection design TTL - compatible logic levelsVoltageTo trigger (low) Logic level 0: 0V ~ 0.4VNormal (high) Logic level 1: 3.1V ~ 30VCurrent 10mA ~ 100mADOConnection design Transistor (Open Collector)Voltage & Current < 24V DC, < 50mATypical ConnectionBased on these specifications, if the DI device has a voltage of 0V ~ 30V or the DO device has avoltage of < 24V (< 50mA), then the camera can supply internal power to these devices and thereis no need to connect the DI/DO device to an external power source.In this case, wire connection to Pins 1 to 4. Use the DIO GND and DI pins to connect a DI deviceand use the DIO PW and DO pins to connect a DO device. See wiring scheme below:
