Gad 42 Configuration; Remote Transponder Configuration (Gtx 32 Or Gtx 33 Only) - Garmin GTN 625 Installation Manual

6.9.4

GAD 42 Configuration

The GAD 42 can be configured by the GTN if an
ARINC 429 input is connected to the GAD 42 and
an ARINC 429 output from the GTN is connected to
the GAD 42.
Access the GAD 42 Configuration page, as shown
in Figure 6-40, by touching the 'GAD 42' key on
the External Systems page. The GAD 42
configuration page allows remote configuration of
the GAD 42 Interface Adapter Unit. For details on
how to configure the unit, see Section 5 of the
GAD 42 Installation Manual (P/N 190-00159-00).
6.9.5 Remote Transponder Configuration
(GTX 32 or GTX 33 Only)
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 6.6.4. Next, go to the External Systems
page and touch the 'XPDR' key. This key displays a
page which allows the remote transponder to be
configured.
NOTE
If the GTN is not communicating with the 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.
6.9.5.1 Transponder Inputs and Outputs
Access the XPDR Input/Outputs page, as shown
in Figure 6-42, by touching the 'Inputs and
Outputs' key from the XPDR Configuration page.
The transponder RS-232 port inputs can be
configured by the GTN. RS-232 Port 1 input for
the transponder can only be set to Remote, and is
the default for Port 1 input. RS-232 Port 1 is used
for control and remote configuring of the
transponder.
