GNS 480 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. GNS 480 SERIAL PORT CONFIGURATION (RX / TX):
SERIAL PORT 1: MAPMX / MAPMX (GNS 480 #1 ONLY)
SERIAL PORT 2: CROSSFILL / CROSSFILL
SERIAL PORT 6: SL70 / SL70
SERIAL PORT 8: ALT ENC / ---
4. MX20/GMX 200 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 GNS 480'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 GNS 480 SHOULD EACH HAVE ALTITUDE INPUT DIRECTLY. THE SL70/70R DOES
NOT REQUIRE A DIRECT ALTITUDE CONNECTION, SINCE EITHER GNS 480 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. GNS 480 RS232 CHANNEL 6 IS OPTO-ISOLATED, ALLOWING TXD6 FROM EACH
GNS 480 TO BE CONNECTED IN PARALLEL.
IF THE GNS 480 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 GNS 480 #2 SHOULD NOT BE CONNECTED.
REFER TO SL10/SL15 AUDIO PANEL INTERCONNECT DIAGRAM FOR ADDITIONAL
INFORMATION ABOUT CONNECTING THE PA MUTE OUTPUT.
