Appendix E: Encoder Serial-to-Gray Code Converter Installation
INTRODUCTION AND DESCRIPTION
The Encoder Converter is an electronic device that receives the serial encoder data from the
EFIS-D100 and outputs standard Mode-C parallel Gray code into your Mode-C transponder.
This Encoder Converter requires data from the EFIS-D100 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.

RECOMMENDED WIRING P
NOTE: Use correct splicing techniques for all electrical connections, taking care to properly
insulate any exposed wire. A short circuit between any of the wires may cause damage to the
Encoder.
The wire used in construction of your Encoder Converter is 22 gauge avionics grade Tefz
which meets Mil Standard MIL-W-22759/16.
Installing: Make sure all connections are secure and all wires are routed and strain relieved to
ensure that the wires will not chafe against any other object in the aircraft.
