SCXI-1349 Cable Adapter Pin Assignment

[S21401]

Good Morning,

      We have the SCXI-1349 Cable Adapter between the NI 4472 Adapter and SCXI-1520 module but there seems to be a discrepancy for pin assignments in the manuals.

            SCXI-1349 

Chan.  68 Pin  50 Pin  1520 Manual (Rear 50 Pin Connector)

+0        68        01        03

-0         34        02        04

+1       33        03        05

-6         58        22        16

+7        57        24        17

-7         23        23        18

     May I ask where to find the Correct Pin assignments for the 1349 and 4472 Adapter?

Thanks

Hi Joe D,

M-Series Breakout Pin Translations for the SCXI-1349 and SCXI-1346 agrees with the SCXI-1520 manual. The SCXI-1349 Shielded Cable Adapter Installation Guide that is on the web doesn't have any pinouts as far as I can tell. Which documentation did you get the middle column from?

Hi Brad,

    The middle column is from the 68 pin output connector to the 50 pin input connector on the 1349 via ohm check.

Thanks for the note

Hi S21401,

I have successfully used the break out pin conversion table that Brad K has posted. Would you mind trying your test again? Also, what is your application? Are you trying to build a custom connector? How exactly are you interfacing the 4472 with the 1520?

Good Morning,

   1520 module to 1349 adapter to 4472 adaptor, the adaptor we thought was an 1349 is not a 1349. I have not been able to id the adaptor we have with the numbers found on the part(183137B-01) but after borrowing a 1349 ,the table Brad gave is true. I want to thank everyone that helped us,I'm sorry I did not post our solution/find yesterday when we found the problem.

Regards

Hi Joe D,

It looks like you have an SCXI-1353 kit, which includes an SCXI-1349 and an SCXI AI-48/DIO-24 adapter, which is the mystery connector:
