Transistor (Open Collector)

Voltage & Current

< 24V DC, < 50mA

Typical Connection

Based on these specifications, if the DI device has a voltage of 0V ~ 30V or the DO device has a

voltage of < 24V (< 50mA), then the camera can supply internal power to these devices and there

is 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 device

and use the

DIO PW

and

DO

pins to connect a DO device. See wiring scheme below:
