Notes:
(1) Software configuration commands determine P1 digital I/O pin functions.
(2) Actual shunt-jumper placement is required to provide ±15 VDC to expansion cards or disconnect internal DAC references to
allow externally selected DAC references.
(3) Digital I/O is not available with DBKs due to line use for addressing. “/” indicates the pin can be used for either function but not
both at the same time.
(4) DaqBoard [ISA-Type] P1 is compatible with Metrabyte DAS-16.
(5) The pinout is for ISA-type DaqBoards. It does not apply to PCI or cPCI type DaqBoards.
