I use a FT-7900 with my TNC-Pi9k6.? You need to use the 6 pin mini-DIN connector and not the DB-9.? That way, you don't need to change anything when switching between 1200 and 9600 baud except the settings on the TNC and on the radio.? No switching jumpers or cables.
The pin-out you mention on the PiGate site is just for radios that don't have the built-in packet port.? You *could* set it up through the mic and headset ports, but then you are limited to 1200 baud only.
Please let me know if you have any more questions.

OK I am thinking of trying a TNCPi with a ft 7900r, the pigate site shows the pinout for a FT 2800/2900 using the mic port. My question is my 7900 has a rear data port why can't I use it? Her is a comparison of the 28/2900 mic pinout and my plan for my 7900. Do I need to figure out and use the pinout for the 7900 (MH48A6J) MIC PORT instead? Below left mic pinout from website, Below right my plan for 7900.
