Hello.
I'm currently in possession of TI's EVM ADS1x9xECG-FE (rev A) for the ADS1292R. As far as I've gathered, this board provides me with 1 differential ECG channel and 1 Resp channel, as I can see in the provided software application. Now I wish to have 2 ECG channels to work with, and I understand it is possible to change the board manually (by adding and removing resistors and conductors) to provide 2 channels.
Yet, I wonder if it would not be easier to order the ADS1x9xECG-FE EVM for the ADS1292 (without respiration). As I understand, it provides 2 ECG channels instead of 1 EGC and 1 Resp. It might be a quicker option and less messy, and yet, I have ran into several questions I hope you can help me with:
1) I've looked into the documentation of the EVM, and yet I can't find the difference between the circuits connecting the 9 pin socket and the ADS, which should be different between the ADS1292 and the ADS1292R. (Considering the ADS1292 does not have a respiration function and so the circuit is redundant.)

what are the changes? Where can I find documentation of the changes?
2) Are there any other fundamental changes between the boards that would affect use and I should know about? It seems that both ADCs function the same in the ECG field and I should not have any problem adapting, yet I want to be sure I'm not missing anything.
Thank you very much for your time.
