5.5.4.6 GAD 42 Configuration
The GAD 42 can be configured by the GTN if an ARINC 429
input is connected to the GAD 42. To configure the GAD 42,
select the External Systems page group and then touch the
GAD 42 key.
The GAD 42 configuration page allows remote configuration
of the GAD 42 Interface Adapter Unit. For details on how to
configure the unit, see Chapter 5 of the GAD 42 Installation
Manual, P/N 190-00159-00.
5.5.4.7 Remote Transponder Configuration (GTX 32 or GTX 33)
A remote transponder can be configured by the GTN via RS-232 if a transponder is configured for one of
the RS-232 ports. To configure the transponder, it must first be selected as present and the type of
transponder installed must be specified. To do this, see Section 5.5.1.4.4. Next, go to the External
Systems page and touch the XPDR key. This displays the page shown in Figure 5-32, which allows the
remote transponder to be configured.
NOTE
If the GTN controls any transponder (GTX 32/33/327/328/330), then that transponder
will boot into the same mode (Normal or Configuration) as the GTN.
NOTE
If the GTN 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. If the fields are
dashed out, check the wiring and pin connections from the GTN to the transponder.
NOTE
The GTN can interface to the GTX 327/328/330/330 ES; however, configuration of the
panel-mounted GTX 327/328/330/330 ES is not supported. These transponders should be
configured per their installation manuals rather than through the GTN.
