Operation Theory
3.8 Physical Location of the PXI and PCI Digitizer
3.8.1 Identify PXI Digitizer’s Physical Location by Geo-
graphic Address
CompactPCI and PXI chassis accommodate slot numbering
mechanism based on the definition of Geographical Address pins
on its backplane. Users can identify module’s physical location by
reading back Geographical Address. This is a useful feature espe-
cially when multiple modules are installed in one host system. The
PXI-9816/26/46 can read back the Geographical Address through
software driver. Please refer to software function reference man-
ual for more detail description.
3.8.2 Assign a Board ID to a PCI Digitizer
When users plug two or more PCI-9816/26/46 modules in one
computer, board ID provides an effective mechanism for user to
identity the specific module. With this method, users can access to
specific module in accordance with board ID. The dip switch of
board ID is located on the top of the module. Please refer to fol-
lowing figure and table for detail setting.
Please note that users have to assign a unique board ID to each
module that are installed in the same computer, otherwise soft-
ware driver will not allocate correct system resource to these mod-
ules. Once users assign identical board ID to different module,
please turn off your computer first and then adjust the board ID
again. After correct board ID is assigned, then users can power up
computer again.
