Error 50405 - USB 6008 OEM.

[VeeJay]

Hi everyone,

Occurs on a digital output line daqmx. I am trying to use 5VDC from digital output to energize a solid state relay D2425 (Crydom) to control a 120VAC 1/3 HP motor. I am able to turn the motor ON using task generated on MAX, but when I try to turn OFF I get the error - 50405 DAQ Assistant error.

I have tried using a different USB port but didn't help. I removed all other USB devices as well. The DAQ card is the only USB device; so not being able to source power from the computer shouldn't be an issue.

The SSR has it's inputs and outputs very well isolated. Could there be any other issue?

OS: Windows 7

LabVIEW version 2010 SP1 (when I initially installed LabVIEW, daqmx didnot install. I downloaded 1.2GB of daqmx 9.2.3 and installed it separately)

Sorry for the double post. I cancelled the previous one,but somehow got posted. This has more information.

Not enough information. Post your code along with the MAX task that you created. This sort of operation is usually trivial and can be easily done without the overhead of the DAQ Assistant. It's only a DAQmx Write after the create channel.

I'me having the same problem. Did you manage to find a solution?

Hello,

Have you taken a look at this KB?  It outlines one possible solution when seeing this error.  If that doesn't work, I'm afraid we will need more information about your setup and the issues you are having.  Thanks!
