the wiring step of this installation.
If your Altitude Transponder has either a strobe signal or a D4 pin, leave these pins unconnected.

The Gray code output of the Encoder Converter reports altitude not adjusted for barometric
pressure, as required by FAA specification. The altitude reported by the EFIS-D6 encoder will
always match the altitude shown on screen when the BARO value is set to 29.92 inHg.
STEP 2: CONNECTING TO THE EFIS-D6
Before wiring connections to the EFIS-D6 check to ensure that the wire length between your
Encoder Converter and your EFIS-D6 is appropriate. Add or remove wire length if needed or
desired. Customizing the wire length will facilitate an installation that is both cleaner and more
secure.
The only pins of interest on the EFIS-D6 connector for the Encoder Converter installation are
pins 13 and 21. The two wires exiting the Encoder Converter are the EFIS-TX and the EFIS-
Ground, which are green (or red) and black respectively, and 2 feet in length. Connect these
wires to the EFIS-D6 25-pin female harness.
Ensure that your EFIS-D6 is powered off. Then connect the black EFIS Ground wire to pin 21.
Then, connect the green wire to pin 13 (Serial Encoder Transmit) on the EFIS harness.
