Good to see you've had a look through the MOS guide, I understand it's definitely not ideal, but nearly all the information is the same. One exception being the pin out.
The pins to use will be the ones on that white 4 pin communication and power header. If you've got the MOS version of the AL202C manual
, you'll see this connector in detail on page 5. Essentially, the pin out will be the same, except Rx will be SCL, or clock, and Tx will be SDA, or data. If you don't have the manual handy, that's going to be VCC, SCL, SDA, GND reading from the GPO side over to the edge of the board.
That should get you on the right track, I understand there is little support out there for those MOI units right now, so if you've got any more questions, please feel free to post them here.
