PXI 2527 1-Wire Dual 32x1 Multiplexer Topology Documentation Error

[apna]

Hi,

        I configured the PXI 2527 switch in 1 wire Dual 32*1 Multiplexer topology. When we close the switch channels (both in software and in NI Swith Front panel) only 32 channels are accessible. i.e.  In bank 0 When we close the channels ch0 to ch15 we are able to get the continuity between respective channel and com 0+. Similarly in bank1 when we close the channels ch48 to ch63 we are able to get the continuity between respective channel and com 1+.

       But when we close the channels ch16 to ch 31 in bank0 or ch32 to ch47 in bank1 we are not able to get the continuity between the respective channels and com0+ or com1+ respectively.

      But the switch help shows that there are 32 channels available in each bank.

      Please let me know how to proceed on this.

     Regards,

Lakshman

Hi Lakshman,

Terribly sorry for the confusion.  I believe you have found a documentation error, and that is why you are having difficulty with the PXI-2527 configuration. 

The NI Switches Help currently shows an incorrect software (SW) name to hardware (HW) name cross-reference, included below under CURRENT.  I have also included the correct information under CORRECT.  A Corrective Action Request (CAR) will be filed to fix the documentation error.
