How to troubleshoot working of USB 6211 digital IO

[ksumesh61]

My USB 6211 digital IO has suddenly stopped giving digital output. Board when connected, LED blinks and it passes self test. But refuses to give any digital output. Can anyone please help me out?

Does it work in test panels?

Can you measure the voltage at the port/line with a multimeter, disconnecting the DAQ from any external circuitry?

Is it just one line or one port?  Or is every digital output on there broken?

Thanks for your reply.

Test panels are not working. That is no signals at the digital output port or line. I have not connected any load while measuring.

Hoping to hear from you for some solution!

If the digital lines are not generating from control of the test panel, then there is a good chance you might have damaged the device. Can you read digital signals with the lines? What happened from the time the board was working till the time it stopped working?

Do other components of the 6211 work? Can you get analog output?

Thank you for your time. Technical person arrived and found out that Terminal connector was loose. Problem is solved
