General Information
GNS 480 (CNX80) Installation Manual 560-0982-01 Rev L 1-5
1.2.2.5 Annunciator Outputs and Switch Inputs
The GNS 480 can drive various external annunciator lamps and receive inputs from various switches to
control the GNS 480 operation. This allows for remote operation of the GNS 480 if desired for a specific
installation.
1.2.2.6 RS-232 Interfaces
The GNS 480 has seven external, user-configurable RS-232 serial ports (five are bi-directional, and two
are receive-only). The serial ports can be configured to receive RS-232 serial data from various sources,
including another GNS 480, SL30, SL70/SL70R, MX20/GMX 200, GDU 620, FADC, Altitude Encoder,
GTX 33/330 transponder, GTX 32/327 transponder and a CO Guardian (COG) carbon monoxide sensor.
These ports can also be configured to transmit RS-232 serial data in various formats, including
MAPCOM. These outputs allow the GNS 480 to transmit data to the MX20/GMX 200, GDU 620, SL30,
SL70/SL70R, GTX 33/330 and GTX 32/327. In addition, the GNS 480 can transmit data to any unit that
accepts the standard Garmin AT MAPCOM data.
1.2.2.7 RS-422 Interfaces
The GNS 480 has one user-configurable, bi-directional RS-422 port. This port is not currently used.
1.2.2.8 ARINC 429 Interfaces
The GNS 480 has three ARINC 429 input ports and two ARINC 429 output ports. Each port is user-
configurable for low or high speed operation. The GNS 480 can be set up to receive air data, heading
data, wind data or traffic data from suitable equipment. The outputs can be set up to output ARINC 429
data in various formats.
1.2.2.9 Baro Correction Input
The GNS 480 has one interface that allows a baro correction potentiometer to be connected directly to the
GNS 480. This input can be calibrated at installation, allowing a wide variety of altimeters to be
connected to the GNS 480.
1.2.2.10 Synchro Input
The GNS 480 has one XYZ synchro input that allows synchro heading to be supplied to the GNS 480.
1.2.2.11 Message Audio Output
The GNS 480 has one 500
Ω
audio output that can be connected to an audio panel to provide audible
messages to the pilot. This output can be automatically inhibited by other equipment if required.
1.2.2.12 Infrared Interface
The GNS 480 has one user-configurable bi-directional infrared port. This port is not currently used but in
the future might be used to send and receive flight plan and user waypoint information through a PDA that
has infrared capabilities.
