PCLD-8751 and PCLD-8761 require a +5V power supply for correct operation. When using the SCSI 68-pin connector, the card can be pow- ered directly from the PC’s I/O bus by connecting CN1 to any Advantech PC-LabCard product. However, it is also possible to connect external supplies to PCLD-8761 by connecting an external power supply to terminal TB7. -
