CN1-1 Used to input 24VDC (200mA) for I/O interface. The power supply
capacity changes depending on the number of I/O interface points to be
used.
For a sink interface, connect the positive terminal of the 24VDC external
power supply to DICOM.
For a source interface, connect the negative terminal of the 24VDC
external power supply to DICOM.
