Altitude Encoder with Mode S Transponder

Looking at upgrading some avionics and trying to price it up...

Throwing out a Bendix King Transponder and replacing with a shiny Garmin GTX328 S Mode.

Do you need an altitude encoder with the 328? I have an Ameri King which states Mode C on it, can I use it for the 328 as well or is there a different encoder required (at additional cost?)

thanks all
