2 questions about pin referencing on PCI 6225 card

[User_1979]

Hi everyone,

I am using for the first time a 6225 PCI card (80 analg inputs). This card is linked to two SCB-68 bloc junctions and my purpose is to use it to acquire 40 différential signals. Using the DAQ assistant I have come up to these conclusions :

  

1)      The first 8 of my 40 différential inputs go onto the first bloc junction?

2)      On bloc junction n°1 for each differential signal I need to put a 10 Kohms biais resistance between each AIGrnd and the V(-) of the signal. This is what I have done with other 622X cards. In order to do this with bloc n°2 too, I only have pin n°22, 9 and 43 free to use for all my 32 signal. Is this correct?

I know these are 2 very basic questions but  if somebody could just answer them for confirmation it would be great.

Thanks a lot,

Hi,

1) Indeed you have the first 8 of 40 differential inputs on sur connector 0

2) Exact, you have 3 AI gnd on connector 1 with pin number 9,22 and 43
