Appendix E: Encoder Serial-to-Gray Code Converter Installation
IN O PTION
The Encoder Converter is an electronic device that receives the serial encoder data from the
EFI D to your Mode-C transponder.
This Encoder Converter requires data from the EFIS-D10A and is not to be confused with other

important that you install the unit correctly. The Encoder Converter does not output an encoder
strobe signal.
The Encoder Converter is designed to be powered off voltages between 10 and 30 volts.
TOOLS AND EQUIPMENT
The following parts are not included with your Encoder Converter purchase but m
necessary to complete the installation.
 Wire cutters
 Connector crimp tool
 Crimp pins
 25-pin EFIS harness to mate with EFIS-D10A (may have been purchased with your

The wire used in construction of your Encoder Converter is 22 gauge avionics grade Tefzel wire,
which meets Mil Standard MIL-W-22759/16.
Installing: Make sure all connections are secure and all wires are routed and strain relieve
ensure that the wires will not chafe against any other object in the aircraft.
STEP 1: TRANSPONDER WIRING
Wire the Encoder Converter signals to their respective connections on your Mode-C transponder
Mode-C transponder pin-outs vary from device to device. To find the correct pin-out, look at t
manual for your transponder or contact its manufacturer. The table below details which co
wire should be connected to each Transponder pin. All of the wires listed in the table leave one
the Encoder Converter in a single bundle. If your transponder has a switched power
