Pin-outs on NI 6251

[morgois]

Are the pin-outs on the 6251 correct as listed in the documentation? I am trying to wire a simple output board that just has one AO and one AI channel and one digital channel to BNC. That's all. But it doesn't work at all. However, the BNC-2110 works just fine. Are the pin-outs listed correct?

Hello,
There have been no reported misrouting of pinouts or signals on the 6251. Do you have a basic breakout board like a CB-68LP or SCB-68 that you can test without using the BNC-2010? From documentation for the M-series channel 0 input should be pin 68(+) and 34(-) if you are using differential input. The analog output should be connected to Pin 22(+)for AO 0 and pin 54 or 55 for the ground side. Pin 52 is digital channel 0 with pin 53 being the ground side for that. Is this what you are seeing in your documentation? If not, please, post back
and let us know.
