Hmmmmmm, very complicated subject.
Well, first of all, ALL 1997 are DAS-X. On the 129 and 140, there is NO IR receiver on the rear view mirror. There are 3 IR receivers on the 129 and 140, which are located at both front doors and the trunk. You wouldn't be able to try to change any of these components from factory configuration, everything is VIN-specific, and I am unsure if the IR signal is rolling code, I rather doubt it.
There were no revisions to the system, all 1997s are DAS-X.
1996's are DAS-2, they have the IR receiver in the rear view mirror.
One thing did happen in 1996 similar to what you are discussing in relation to a mid-year change. The E420 initially was equipped with DAS-2, but from 1/96 to 6/96 the E420 was produced with a system called DAS-2a, which is similar to DAS-X. Starting 6/96 then all MB's sold in the US were DAS-X.

PS On the 97 202 and 210's, they DID have the interior rear view mirror receiver, plus receivers on the front doors only, not the trunklid.
