Note: Software configuration commands determine P1 digital I/O pin functions. Actual shunt-jumper placement is required to provide
±15 VDC to expansion cards or disconnect internal DAC references to allow externally selected DAC references. Digital I/O cannot
be used with DBKs. “/” indicates the pin can be used for either function but not both at the same time.
Note 1: Refer to the Power Management section in the DBK options manual (p/n OMB-457-0905).
Reference Note:
The Power Management section of the DBK Option Cards and Modules User’s Manual (p/n OMB-457-0905)
contains additional power-related information. As a part of product support, this manual is automatically loaded
onto your hard drive during software installation. The default location is the Programs directory, which can be
accessed through the Windows Desktop.
