3.2.1.2 ARINC 429 Ports

While on the Ground Maintenance SETUP menu page, press the 429 PORTS line select key to
configure the ARINC 429 ports. The ARINC 429 ports setup page is shown in Figure 3-3.
Push in the Cursor knob to allow editing of the settings. Turn the large, outer knob to select the next or
previous item and the Cursor knob to change currently selected setting. Set each ARINC 429 port
according to the installation, and leave unused ports set to NONE. Either press the Cursor 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 available ARINC 429 input and output port settings are
shown in Table 3-2, and the definition of each available configuration is found in section 2.8.10.2.
The Source Destination Identifier (SDI) field on the EFIS ARINC 429 input can be configured as SYS 1
or SYS 2 and should be set according to which system (#1 or #2) the GNS 480 is in a particular
installation. However, other inputs (ADC, AHRS) are accepted regardless of the SDI, and are indicated
with ALL in the SDI column (the value of ALL cannot be changed).
The SDI field on the ARINC 429 outputs can be configured as SYS 1, SYS 2, or ALL. For dual GNS 480
installations, each GNS 480 must have a unique source name (SYS 1 or SYS 2). For a single GNS 480
installation, select ALL.
