The device I built is a clone of the Icom CT-17, which is an RS232 to TTL 
converter.  Some Icom radios also required an internal UX-14, which are a 
rare find, and most of them are already in the hands of those who need 
them.  The UX-14 is a CI-4 to CI-V interface convertor, I believe.

I recommend an excellent website of resources for the Icom CI-V system, 
which I learned about AFTER I built my interface:


The one I built is:
Interface using MAX232 IC (from the ICOM CI-V spec. 1986)

I'm about to build another design that will fit in the DB25 connector and 
does not require external power.

Good luck!
