CNX80 INSTALLATION DRAWING
NOTES:
1. ALL WIRES 24 AWG OR LARGER UNLESS OTHERWISE SPECIFIED.
2. AT GARMIN AT EQUIPMENT CONNECT SHIELD GROUNDS TO THE REAR OF THE
MOUNTING FRAME ON THE CONNECTOR PLATE -- THE SHIELD LEADS MUST BE LESS
THAN 3.0 ". UNLESS OTHERWISE NOTED, CONNECT OTHER SHIELD GROUNDS TO
AIRCRAFT CHASSIS WITH AS SHORT A CONDUCTOR AS PRACTICAL.
3. CNX80 SERIAL PORT CONFIGURATION (RX / TX):
SERIAL PORT 1: MAPMX / MAPMX (CNX80 #1 ONLY)
SERIAL PORT 2: CNX80 / CNX80
SERIAL PORT 6: SL70 / SL70
SERIAL PORT 8: ALT ENC / ---
4. MX20 EXTERNAL DATA SOURCE CONFIGURATION:
EXTERNAL GPS POSITION SOURCE: PORT 1
ALTITUDE SOURCE: PORT 1
NAV SOURCE: NONE
5. THE SL70/SL70R MUST HAVE SOFTWARE VERSION 1.3 OR HIGHER IF IT IS DESIRED
TO HAVE BOTH CNX80'S REMOTELY CONTROL IT.
SL70 SERIAL PORT CONFIGURATION:
ALT SOURCE: SER
BAUD: 9600
TX: EXT
SL70R: GRAY CODE ALT PGM PIN 36 MUST BE LEFT OPEN.
6. EACH CNX80 SHOULD EACH HAVE ALTITUDE INPUT DIRECTLY. THE SL70/70R DOES
NOT REQUIRE A DIRECT ALTITUDE CONNECTION, SINCE EITHER CNX80 CAN SUPPLY
ALTITUDE TO THE TRANSPONDER.
7. ALTITUDE ENCODERS ARE NOT GARMIN AT-PROVIDED EQUIPMENT. REFER TO THE
APPROPRIATE ENCODER INSTALLATION MANUAL TO ENSURE PROPER
CONNECTIONS.
8. SHIELDS FOR AUDIO CABLES SHOULD BE GROUNDED AT ONE END AND LEFT
FLOATING AT THE OTHER END. IF SHIELDED AUDIO CABLE IS CARRIED THROUGH
DISCONNECT, CARRY SHIELD GROUND THROUGH DISCONNECT ON SEPARATE PIN.
9. CNX80 RS232 CHANNEL 6 IS OPTO-ISOLATED, ALLOWING TXD6 FROM EACH CNX80
TO BE CONNECTED IN PARALLEL.
IF THE CNX80 MESSAGE AUDIO OUTPUT IS CONNECTED TO AN UNSWITCHED AUDIO
INPUT, IT IS RECOMMENDED THAT THE THE SL15 AUDIO ACTIVE OUTPUT BE
CONNECTED. THIS OUTPUT IS ONLY AVAILABLE ON CERTAIN SL15 AUDIO PANELS.
ALTERNATE CONNECTIONS ARE SHOWN ON THE SL10/SL15 AUDIO PANEL
INTERCONNECT DRAWING. CONSULT THIS INTERCONNECT DRAWING THE
APPROPRIATE INSTALLATION MANUAL FOR INFORMATION.
THESE SIGNALS ALSO GO TO THE AUTOPILOT AS APPROPRIATE.
12.THIS DIAGRAM IS PROVIDED TO SHOW THE INTERCONNECTION BETWEEN GARMIN
AT UNITS. FULL WIRING DIAGRAMS FOR EACH UNIT ARE PROVIDED IN THE
APPROPRIATE INSTALLATION MANUALS. REFER TO ALL DOCUMENTATION TO
ENSURE SUCCESSFUL INSTALLATION.
THE AUDIO MESSAGE OUTPUT FROM CNX80 #2 SHOULD NOT BE CONNECTED.
REFER TO SL10/SL15 AUDIO PANEL INTERCONNECT DIAGRAM FOR ADDITIONAL
INFORMATION ABOUT CONNECTING THE PA MUTE OUTPUT.
