Mares M2 Download cable?

[PTAaron]

I thought for sure I saw someone post up about making their own download cable for a Mares M2 ... but I can't seem to locate where I saw it.

Anyone have any tips on making one? My father in-law has a M2, and I'm just trying to help him out.

I tried to make one, spent couple of weeks tweaking it on the breadboard. Finally gave up and bought one on sale. USB/RS-232 worked, the problem was the IR in/out module.
