3.2.1.8 GTX Transponder Setup Items
The GTX Setup function is used to configure the GTX transponder – if no GTX transponder is setup, this
menu choice will not be displayed. The menu that is displayed when the GTX line select key is pressed
depends upon what version of GTX transponder is configured on serial port 6 (refer to 3.2.1.1). The GTX
Main Setup menu is shown in Figure 3-12.
Refer to the appropriate GTX transponder installation manual for a additional information
on the parameters that can be configured via the GNS 480.
If the GNS 480 is not communicating with the GTX transponder, all of the editable fields
for the setup items shown in the following sections will be dashed out.
