The Ethernet-based HSDB (High Speed Data Bus) meets the hardware aspects of IEEE standard 802.3 for
10 base T Ethernet communications.
5.2.6 Main Audio Output
The main audio output is used to play the ‗clicks‘ associated with the touch screen, as well as TAWS
alerts on GTN units that are equipped with TAWS.
Pin Name Connector Pin I/O
AUDIO OUT HI P1001 4 Out
AUDIO OUT LO P1001 23 Out
The audio output will be 60 mW across a 500Ω load.
5.2.7 Main Indicator
5.2.7.1 Main Indicator Function
The Main Indicator displays both lateral and vertical deviation from selected course, To/From indications,
lateral and vertical flags and superflags.
The ―CDI‖ key on the screen of the GTN takes the place of remote ―NAV/GPS‖ switches, and is used to
toggle between display of GPS and VOR/ILS navigation on a remote indicator. The navigation source is
annunciated on the display below the ‗CDI‘ key. The navigation method is optionally annunciated
externally by connecting to the VLOC ANNUNCIATE output (P1001-52) and GPS ANNUNCIATE
output (P1001-15). GPS and VOR/ILS navigation may be toggled externally when the CDI SOURCE
SELECT input (P1001-39) is momentarily grounded. See Section 5.2.9 and 5.2.10 for more information
on the discrete inputs and outputs.
An OBS resolver connection to the GPS is preferred, but not required. For the GTN 650, an OBS
resolver typically is connected to the MAIN OBS inputs for use with the VOR receiver.
