I am using a BNC 2110 board connected to a PCI 6251 and I need to connect it to a type T thermocouple, but I am unable to get a sensible reading when I run the Measurement and Automation Explorer. I want to set up a voltage differential channel so I can just read in the voltage difference on the thermocouple.
My first issue is connecting the thermocouple to the BNC board. When I am trying to set up the channel in the Explorer and I look at the connection diagram, it says: "the connection diagram tool does not support the accessory on connector 0 of your device: BNC 2110." So I have to choose a Supported Acessory, usually I select SCB-68 (but the other option give the same result). The problem with this is that this diagram says I need to connect to ports 34 and 68, which correlate to the same Analog input on the BNC 2110. All the other channelsI can select have similar issues: either the ports are the same input on the BNC or one of the ports doesn't have a correlation on the BNC 2110. So I'm not really sure where to attach the thermocouple wires... I have tried multiple things, including just putting one of the wires in the BNC inpu that correlates to the ports and just putting the other wire in the next input; this causes the readings on the explorer to fluctuate very rapidly in the 0-1 mV range even when I heat the thermocouple junction, so I do not think it is the proper connection.
Help please... Thanks!
