Select either Present or Not Present. If present, touch GDL 88 to select the external traffic source (None,
TCAD, or TAS/TCAS) connected to the GDL 88 and the GDL 88 ADS-B transmit state (Enable or
Disabled). Configuration of these parameters enables portions of the GDL 88 user interface in normal
mode and does not configure the GDL 88. For more information on configuring the GDL 88, refer to the
GDL 88 STC Installation Manual, P/N 190-01310-00.
5.5.1.4.4 Transponder #1 and Transponder #2
Select either GTX Mode C, GTX Mode S, or GTX Mode S+ based upon the interfaced transponder
type. If the type of transponder connected to the cross-side navigator is GTX w/TIS or GTX w/TIS+,
select GTX Mode S or GTX Mode S+, respectively.
Note that if the correct data format is selected on
the RS-232 configuration page, this will be filled in and grayed out. Ensure the correct transponder type is
displayed. Also, the transponder should be configured as present even if it is connected to the other
installed GTN. This setting enables the user interface in normal mode.
5.5.1.4.5 GWX (GTN 7XX Only)
Select either Present or Not Present. If Present, select GWX 68 or GWX 70, based upon the installed
radar.
NOTE
If an ARINC 708 weather radar is configured, the Present key will not be available for
selection for the GWX weather radar.
