What do the lights on the front of the PXI-6551s mean?

[Havarti]

We have 5 PXI-6551s in a pxi 1006 chassis. When we use the devices, two of them have a red active lights on the front the other three display an orange active light. What do the different colors of the access and active lights mean?

Hi Brian,

Thank you for using the PXI-6551 boards.

The answer to your question is best described by a table in the help file, which you can find by going to Start --> Program Files --> National Instruments --> NI-HSDIO --> Documentation --> NI Digital Waveform Generator/Analyzer Help.

In the help file, select the Contents tab, then go to Devices --> NI 655X --> Channel Interface --> LED Indicators.

That table shows the different possibilities for the LEDs and what each case means.

Best Regards,
Allen
