Issue Details

I have more than 1 NI PXIe-2527 and I need to merge those to have a larger multiplexer: for instance the NI PXIe-2527 can be configured as a 64x1 multiplexer and by merging 2 of those I could create a 128x1 multiplexer. How can I do it? 

Solution

Normally this is possible by shortcircuiting the COM output of the boards on the terminal block. For example in the case of the NI PXIe-2527 the connector block (NI TB-2627) provide a connector that facilitate the connection:

For instance if you need to connect 2 Switch, you have to connect the COM0+ with the COM0+ of the other Switch and the same for the COM0-.
