Cyton Getting Started Guide, "Hardware Settings" screenshot incorrect
Hello everyone,
I'm relatively new to OpenBCI and to get familiar with it, I started by looking at the Cyton getting started guide.
However there are some things that are confusing me.

In this tutorial you are using channels 2, 4 and 7 for different bio potential measurements, being channels 2(N) for (Fp2) and 7(N) for (O1) for EEG plus Bias and Reference (SRB2) and channel 4 (N) and (P) for ECG.
Then you mention "We will be removing pin 4 from SRB2 so that it is not included in the same reference signal being used to measure brain waves" but later on there's this screenshot:

Since I'm not sure the image is posting correctly, on the image you have the channels and their configurations like this:
Ch -PGA - Intput - Bias - SRB2 - SRB1
2 -x24 - Normal - Don't Include - OFF - No
2 -x24 - Normal - Don't Include - OFF - No
4 -x8 - Normal - Include - ON - No
7 -x24 - Normal - Include - ON - No
I think the configuration should be like this:
Ch -PGA - Intput - Bias - SRB2 - SRB1
2 -x24 - Normal - Include - ON - No
2 -x24 - Normal - Include - ON - No
4 -x8 - Normal - Don't Include - OFF - No
7 -x24 - Normal - Include - ON - No
because we don't want channel 4(ECG ) using the same reference than channels 2 and 7 (used for EEG).
Is the image wrong? or, there is something I'm missing or interpreting wrong? Probably I'm misinterpreting the way SRB1 and SRB2 work.
I'll wait for your answer, and thanks in advance for taking the time to reply.
