3.2 I/O Address Map
Depending on which card is used, either the cPCI/PCI-6208V or PCI-
6216V, there are 8 or 16 voltage output channels respectively. For the
cPCI/PCI-6208A, there are 8 voltage and current output channels; the
voltage output controls the current source. The programming methods of
all analog output channels are identical. For the three different models of
the analog output cPCI/PCI cards, the programming methods are
compatible.
The 6208 registers are all 16 bits. Users can access these registers with
16-bit I/O instructions. The following table shows the address of every
analog output port relative to the base address. Note that the base
address is assigned by the PCI BIOS. The current output control for the
cPCI/PCI-6208A is described in Section 3.4.
