3.2.1 Setup Function
The SETUP function allows the custom configuration of the GNS 480 for each individual installation. The
SETUP function allows the installer to configure the serial and ARINC 429 ports, calibrate the resolver
head (if installed), calibrate the baro potentiometer (if installed), and set COM parameters.
3.2.1.1 Serial Ports
While on the Ground Maintenance SETUP menu page, press the
SERIAL PORTS
line select key to
change the serial port settings. The serial port setup page is shown in Figure 3-2.
Figure 3-2. Serial Port Setup Page
Push the small, inner knob in to enter the editing mode. The first editable item will be highlighted. Use the
large, outer knob to select the next or previous editable data field and turn the small, inner knob to change
the current setting. Set each serial port according to the installation, and leave unused ports set to NONE.
Either press the small, inner knob in again or press the
MENU/ENTER
key to save the settings. Press the
SETUP
or
BACK
smart key to return to the Ground Maintenance SETUP menu. The configuration
options for the serial input ports and output ports are shown in Table 3-1.
NOTE
In order for a serial port to function correctly, the baud rate of the RX and TX channels on
a given RS-232 or RS-422 port must be the same (or the unused channel must be set to
NONE). This must be considered when assigning serial ports to interfacing equipment.
