5.2 Configuration Pages
NOTES
The configuration descriptions given in this section reflect software version 5.00
or higher.
When connecting the GTX 328 to a GNS 480 (CNX80) the transponder can be
configured from either the GNS 480 (CNX80) or the GTX 328. Although
possible from the GNS 480 (CNX80), configuration from the GTX 328 front
panel offers more functions and easier to interpret displays.
Holding down the FUNC key and pressing the ON key provides access to the configuration pages. The
FUNC key sequences forward through the configuration pages. The START/STOP key reverses through
the pages, stopping at the Menu page. The CRSR key highlights selectable fields on each page. When a
field is highlighted, the 0 – 9 keys enter numeric data and the 8 or 9 keys move through list selections.
Press the CRSR key to accept changes. When a field is highlighted, pressing the FUNC key moves to the
next configuration page without saving the changes.
