Interface via DAQmxBase to USB6501 daq

[BrenS]

Hello,

I have a USB6501 which is a 24 line digital I/O. I have no problem using it using the the standard "DAQmx" functions. However as I need to use the device in Linux (redhat enterprise WS3, which is suported), The only vi package available for labview 7.1 Linux is the "DAQmxBase version 1.5". This installs fine and the command "lsdaq" gives a listing of my device "Dev1". However when I attempt to run either my own or one of the examples, it says "Error-200170 occured at physical channel specified does not exist on this device"

Something similiar happens when I use the DAQmxBase in windows. Any help would be great.

Cheers

Hello BJ_phy,

There is a firmware "switch" necessary to move the device from NI-DAQmx to NI-DAQmx Base and vice versa.  Check out this KB:  Using the USB-6008/9 and USB-6501 with NI-DAQmx or NI-DAQmx Base.  That should do the trick, re-post if this does not solve your problem.

Hi Alan,

Thanks for that. That fixed it for both windows and Linux.
