Where can I get a pin diagram for the BNC-2120 DAQ Boaard?

[cjbree]

I am using a NI BNC-2120 DAQ Board and a couple of the pins seem to have been damaged. I was looking for a pin diagram to so that I can check to see what these pins correspond to and if they could be contributing to some of the unusual readings we are getting.

I'm assuming that the damaged pins you are referring to are on the back of the connector block where the cable plugs in.

The BNC-2120 Accessory is able to be used with several different families of data acquisition products, and therefore the meaning of the pins could possibly depend on which particular data acquisition device you are connecting to the BNC-2120.

You can find many of the generic pinouts for E series 68-pin devices in the DAQ-mx Help:

If you are using an M series device, the following lists its corresponding pinout, which is nearly identical:

If you let me know which device you are using and which pins you suspect are damaged, I could give you more information on what effect it might have.

cjbree,

There are a few pins that are repetetive for the 68-pin connectors. For example, pins 4, 9, 12, 13, 15, 35, 36, 39, 44, 50, and 53 are all referenced to the same digital ground plane on E-Series boards. On the other hand, if you have pin 14 (+5V) buried and touching some other pins then you could potentially damage your board.

If by 'damaged' you mean some of the pins are bent, then you can sometimes bend these back into place. As jasonv said, it will all depend upon the board you are trying to use and which pins you bent.
