[ICOM] CI-V from USB - schematic ?

[Walt - WB2VSJ]

I built this one from that list

Works on both my IC-706MKIIG and my Pro II (And also My Radio Shack Scanner)

As John said, it's not that simple, you  need a level converter and that's
what these circuits do.  Good news is that you can probably make one of
these from  junk lying around the shack.

Seems like if a ci-v is only 2 contacts that I can make one from one a USB
to DB9 connector with an adapter or a pair of dikes and a mono plug ????????

Comments ?

I have a 705 MkIIG and it appears the CI-V is not functioning.  What is the
SIMPLEST way to test it?  I have tried 3 USB CI-V cables.  I have tried
another laptop.  No go.  I found another cable that is DB9 to mono plug but
am not sure it is a ci-v cable.  Likely?  Comments?

Thanks es 73, de Jim KG0KP
