uAvionix echoUAT - echoUATmux Harness

Appendix C-11 echoUATmux Harness
The optional echoUAT mux harness allows the echoUAT to be hard wired to a
GTX327/GTX330 transponder to provide squawk and barometric altitude via a direct
interface. The mux harness will not work with a GTX327/GTX330 that is interfaced to a
Grey code blind encoder. The altitude encoder must have an RS-232 output.
Note: uAvionix skyFYX GPS is used as position source in this example. If you
have the skyFYX-EXT or Garmin GPS you will need the GNS Mux on the next
page.
The pin connections for the DB9 are shown below.
