Hello Stefan,
I remember running into some roadblock in doing this, but I don't
remember what it was now... I initially wanted to connect directly to
the K3 as well. I think it was if you had a P3 SVGA, it worked better.
If you get things running on just the K3 send me the info, and I'll add
it to the web page at:
https://www.nk7z.net/adding-external-keypad-k3/
as an addendum to the Genovation page, of course giving you credit for
the work.
73s and thanks,
Dave (NK7Z/NNR0DC)

I did get one reply on this topic. Dave NK7Z has already documented nicely on
his website how to connect a Genovation keypad to the P3. The question was how
to connect it directly to the K3/K3S, if possible at all, in order to free the
P3’s USB-port.
A pre-Genovation "button box" was hooked up to the K3’s RS232 port. It uses its internal memory to
store the macros and not the available K3 macros. In order to be able to get the K3 to recognize and share
several RS232 ports LP-BRIDGE is used to create several virtual serial ports. CAT on one of the virtual
serial ports and the "button box" to another. One has to bridge the real "button box" to
another of the LPBRIDGE created virtual ports, e.g. with a software called VSPE.
It will be up to experimentation if a Genovation keypad can be connected in a
similar way. The difference is that the internal K3/K3S memories have to be
used.
