Hi CAS,
somewhere between 2000 and 2003 we did change the name from E to S on both cards. This was to reflect the fact that they're not strictly E-series, but have always been simultaneous sampling cards.
The only difference between the two cards is that the 6110 (the new card you have) has 4 differential inputs, and the 6111 (original card you were using for development) only has 2 differential analog inputs. All the other specifications are the same.
They will work with the same driver, and the same code should be fine for both.
Thanks
