I uploaded a pdf file of the board at

I am looking at replacing the GTL2002 with 4 opto couplers to break up the ground loop.
The I2C lines are bidirectional. I think I can do it with only the opto couplers and no interface
chip. If it works, this will result in opto isolation and a slightly lower cost.
