ni-9403 only 8 bit on cDAQ-9172

[mike.s]

I have a cDAQ-9172 with a NI 9403. When driving from MAX I get all 32 outputs. When driving from Labview 8.5, I only get 1 8 bit bus <7:0>. Iam also running NI-DAQ8.7.1. How do I get all 32 bits to run in 4 8bit busses?

mike.s,


Welcome to the NI forums. 
In LabVIEW you can specify multiple ports when running one of the
shipping examples that come with DAQmx.


In LabVIEW go to:


Help > Find
Examples


In the Example Finder go to:


Hardware Input and
Output > DAQmx > Digital Generation > Write Dig Port.vi


Here you can specify how many ports you want to write to by
using a ?:? in between port numbers.

I hope this helps!

When I try to use the channels I've created those don't appear in LABVIEW, although, they do in MAX&nbsp;&nbsp; <a target="_blank" href="Loading Image..."><img src="Loading Image..." border="0"></a> They're proven to work but in labview i browse and nothing appears..<a target="_blank" href="Loading Image..."><img src="Loading Image..." border="0"></a>

My problem has been fixed. I had to uninstall and reinstall DAQmx. Now all of the software sees all of the hardware and it all works together. I had upgraded to nidaq8_7_1 and may not have done something right on the install.
