Hi Dennis,
the 7600 logic driver work ok, olny to chnge CI-V address.
Switch vfo a/b is OK
Filters W/N/M is OK
Split is OK
Dual RX is OK but into Logic panel also split button (with DR) is automatically pressed but no execute command to 7610.
Of course the direction command is Logic to 7610.
The CI-V default address into 7610 is 98h.
I hope I have answered all your questions.
I'm ready for other yous question if needed.
Thanks for all
