CNX80 INSTALLATION DRAWING
NOTES:
1. ALL WIRES 24 AWG OR LARGER UNLESS OTHERWISE SPECIFIED.
2. AT CNX80, CONNECT SHIELD GROUNDS TO THE REAR OF THE
MOUNTING FRAME ON THE CONNECTOR PLATE -- THE SHIELD
LEADS MUST BE LESS THAN 3.0 ". CONNECT OTHER SHIELD
GROUNDS TO AIRCRAFT CHASSIS WITH AS SHORT A CONDUCTOR
AS PRACTICAL.
3. THE NAV SELECTION SWITCH IS NOT REQUIRED IF ONLY ONE
CNX80 IS INSTALLED.
4. THE CNX80 WILL AUTOMATICALLY TUNE THE DME STATION BASED
UPON THE VOR STATION THAT IS CURRENTLY ACTIVE.
5. THE DB30 DME TUNING FORMAT MUST BE CONFIGURED TO
MATCH THE DME TRANSCEIVER FORMAT. CONFIG A (PIN 25) USES
PIN 45 (DME CONFIG GROUND) FOR GND, AND CONFIG B (PIN 27)
USES PIN 47 (DME CONFIG GROUND) FOR GND. REFER TO THE
DB30 INSTALLATION MANUAL FOR ADDITIONAL DETAILS.
6. IF NAV 2 IS NOT USED, DB30 PIN 40 MAY BE JUMPERED DIRECTLY
TO DB30 PIN 60.
7. OTHER EQUIVALENT PARTS MAY BE INTERFACED TO THE CNX80.
SEE APPROPRIATE INSTALLATION MANUALS FOR THAT
EQUIPMENT.
