Programming Your VXI-DAQ Module

This section provides an overview of the functions available for

programming your VXI-DAQ modules. Additional information is

available in the NI-DAQ Function Reference Manual for PC

Compatibles.

VXI-MIO Series Modules

The VXI-MIO-64XE-10 is functionally equivalent to the

AT-MIO-16XE-10. Any VI or function valid for the AT-MIO-16XE-10

is also valid for the VXI-MIO-64XE-10. The same relationship exists

between the VXI-MIO-64E-1 and the AT-MIO-16E-1. The channel

numbering scheme for both VXI-MIO Series modules is identical to that

of the AT-MIO-64E-3. The few differences that do exist, such as onboard

memory, are discussed in the Common Questions section of this

document.

VXI-DIO-128 Module

The VXI-DIO-128 currently has no functionally equivalent DAQ

hardware. The following sections list the LabWindows/CVI functions

and LabVIEW VIs you will use to program your VXI-DIO-128.

Note:

You cannot change the direction of the digital lines on the VXI-DIO-128;

64 of the lines are always input and 64 are always output.

LabWindows/CVI Functions

Use the following functions to program the VXI-DIO-128 module. More

detailed information about these functions is available in the NI-DAQ

Function Reference Manual for PC Compatibles.

DIG_Prt_Config

• Ports 0–7 are always input ports and ports 8–15 are always output

ports.

• latchMode is not supported and must be set to 0.

• You must set Direction to input for ports 0–7 and to output for

ports 8–15.
