Power Supply Connections

The power requirement is 12VDC at 100mA. Power to the 232DRIO can be wired through the RS-232 serial port pin #9 (power pin) or by an external power supply through the blue terminal blocks. Serial ports can not provide enough power to supply the 232DRIO’s 100 milliamp requirement.
