Hi, Ryan,
Thanks for your guidance. I really appreciate your help.
Yes, the earlobe electrode is intended to be the reference electrode, I am sorry for not clarifying it before. Now I think I understand the reference electrode connection.
a. If I connect left/right frontal electrode to pin 36/32 of J6 respectively, I can connect the earlobe electrode to pin 35/31/AIN1, is that right? (jumpers the other channels and 33-34 and 29-30 are connected, and SRB1 bit not set)
b. Do you mean I can directly connect the reference electrode on pin6 of JP25 and set the SRB1 bit in MISC1 register without connecting pin 33-34 and 29-30 in J6 because those pins 34 and 30 are already connected to SRB1? How should I set those pins on JP25?
In regard of the Bias electrode, I understand it is like the Right Leg Drive circuit in ECG recording. Should I use pin 4 to connect the bias electrode out? How should I set other pins in JP25?
I am so confused by the “JP81(25) Setting” in the diagram. Thank you so much for helping out.
