PCI 6722 analog output not working

[bacteria]

Hello,

I need to generate a constant output voltage using a PCI 6722 analog output card. The card is connected to a CB-68 LP connector block using RC68-68 cable. I am able to see my PCI 6722 device in MAX. However, when I go to Test panels in MAX, I am not able to change the output voltage using the slider. If I move the output voltage slider to anywhere between -10 and 10 V, the multimeter still reads 1.74 V. In other words, the actual output voltage read by the multimeter does not correspond to what I want. I am using Windows XP Serive Pack 1 on a Dell Pentium 3 machine.

Greetings,

Have you tested multiple analog output channels? Do all of the channels exhibit this same behavior? Are you measuring with your multimeter between AO # and AO GND?

Sorry about all of the questions. Let me know.

yes, i have tested all analog output channel (AO 0 to AO 7) and its the same thing. The output does not go beyond 1.74 V and is erratic.

There are several pins in my CB 68LP connector block that say AO GND. I believe that stands for anlalog output ground. I connect one wire to AO 1 and the other to AO GND. Then I use the multimeter to measure the voltage across these two wires.

Any help is greatly appreciated.

It sounds like you are doing everything correctly. Most likely, you will need to send this device back to NI for repair. You can create a service request in the following location:

Good luck.
