Hello Roberto, In the sub folder "Kenwood" in the SatPC32 program folder you will find a schematic (IF-232c.gif) that shows the pin numbering and wiring between the TS-790's CAT connector (ACC1) and the Kenwood IF-232c and between the IF-232c and the PC's DB9/DB25 serial port.
I had to disconnect the CTS and RTS lines between the interface and PC to get CAT steering working. Please read the "Hints(Radio) .... Kenwood Users", sect. B for detailed hints. The file can be opened from the SatPC32 menu "?".
Also, I have a homemade CAT interface (cheap and easy to build). You will find the schematic in the sub folder "Kenwood" in the SatPC32 program folder (TS790Cat.gif). It works flawlessly.
73s, Erich, DK1TB
