Problem with Connection Diagram - BNC 2110 to PCI 6280

[MiladAk]

Hi,

    I want to read analog input data using BNC 2110 as an interface connected to PCI 6280. In first step I want to use Signal Express to just see the data, but when I choose one of the input channel and then I want to see the connection diagram, I get this message:

------------------------------

The connection Diagram tool does not supprt the accessory on connector 0 of your device:
BNC-2110

Please select one of the following supported accessories to view the connection diagram:

Supported Accessories:
SCB-68

CB-68LP

TBX-68

CB-68LPR

------------------------------

What should I do in this step?

Hi MiladAk,

There is this sentence in the manual "The BNC-2110 is only intended for differential analog input signals". The 16 AI channels on PCI-6280 are mapped to 8 BNC connectors AI0-AI7 on BNC-2110. AI[n] together with AI[n+8] represent one differential channel. It means if you select channel AI0 in Signal Express with differential terminal configuration it will also use AI8. These two channels are represented by one BNC connector (positive connection is center conductor = AI0, negative connection is shielding = AI8).
