GTX 330 Installation Manual Page 5-5
190-00207-02 Revision G
5.2 Configuration Pages
NOTES
The configuration descriptions given in this section reflect software version 3.06.
When connecting the GTX 330 to a CNX80/GNS 480 the transponder can be
configured from either the CNX80/GNS 480 or the GTX 330. Although possible
from the CNX80/GNS 480, configuration from the GTX 330 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.
Changes made through the configuration pages are stored in EEPROM memory. To exit the
configuration pages, turn the power off. Then turn on again (without holding the FUNC key) for normal
operation.
