President uses the 6pin so-called GDCH standard like many other manufacturers. also on Q6 & Q6Pro Adapter must have this pinout as below supports many QX CB and SSB radios, also the small Anytone AM/FM CB radios with 8pin RJ45 connector they don't have 12 volt DC on pin 1 (<> to pin 6 GDCH) The "HAMdaptor" does not support all functions required for the Digimic and was built for the old 5555N. It also works on the 5555N II with microphones that do not require an external power supply from the radio eg wireless bluetooth speaker mics or VOX mics/sets, modern desk mics etc.
