[amsat-bb] Re: IC-910H C-IV control port pinout?

[jonny 290]

It's a mono bus - just data and ground.

If you have a couple of transistors and diodes sitting around you can 
build at least a one way interface, I put one on a
bit of PC board and it works great for both programming my 208h* and for 
controlling my 475.


*208h programming port is the right side of the audio output jack, 
rather than the center pin as in C-IV jacks
