Yamaha command link engine ID problem

[Bhngh]

I put the V16 back on my E127. My command link data seems to work somewhat better. Now when I start the port engine it reads data OK. then when I start the starboard engine, the port engine loses data signal. So I know I'm getting data from both engines.
I can't figure out how to load the V1.12 software on to the ECI 100 though. 1.20
It does have the V1.20 now. I think it had the V1.12 on it when I bought it though.
I'd like to try reinstalling it.
I have it on a chip. And both green lights are on when I turn on the E127 with the V1.12 in the slot. It doesn't load to the E-100 though.
What am I doing wrong?

Thanks Bill
