E series vs S series boards and code

[Sorterralee]

I have inherited a project that uses the PCI 6133 board. The code I found expects a tESeries C++ class in a target application (indicating "AIEX3.cpp" and "AIIRQ2.cpp" in header comments), whereas we have a tSSeries class defined in code that is apparently auto generated. In searching this site, I found a document for major differences between E, M and X series. My understanding is that the 6133 board is S-series. 

So I'm stuck with wondering what the differences are, how the code was generated, and why E series rather than S series code. It is possible that what I have found is a snapshot before the developer had anything complete. I appear also to be missing a "tDIO.h" file.

The previous developer did not keep documentation, or a code revision control system. Our system runs QNX.

Help greatly appreciated.

Based on what you've described, that sounds like the NI Measurements Hardware DDK. ("aiexN.cpp" is the filename convention for examples, and it includes tESeries and tSSeries wrappers.)

Thank you. I have successfully compiled the MHDDK examples found. It does not find the PCI card, but maybe there's something else I have to do. If I can't resolve that issue I will create a new discussion.
