Garmin MX20 - Manual (Page 61)


Detailed Operation
Enter Code (ADS-B Air Traffic Source)
This is where you enter the ATC-assigned ADS-B code. This code entered into the MX20 does NOt control the
code on Mode A, C, or S transponders. It only sends the selected code to the GDL 90 UAT for inclusion into
the position report. The MX20 Code Edit option must be enabled to make this function available.
Set 1200
Pressing the Set 1200 key sets the ADS-B code to 1200. This code entered into the MX20 does NOt control
the code on Mode A, C, or S transponders.
Services
The Services option allows emergency/service codes to be sent over the data-link radio. When pressed, a list of
standard emergency/service codes will be presented. The desired emergency/service code can be selected and
broadcast by pressing the tRANS (Transmit) “smart” key or cancelled by pressing the CANCEL “smart key.”
When an emergency/service code is being transmitted, the Services menu option key label is illuminated. To
terminate the broadcast, press the SERVICES option again. Three of the emergency/service codes temporar-
ily change the ADS-B code value. Once the emergency/service code is terminated, the ADS-B code will revert
back to the previously set ADS-B code. The MX20 must be configured as the UAT’s control panel to make this
function available.

the traffic is shown by the line extending from the point on the end of the traffic arrow icon. The end of the
line shows the point where the traffic item will be at the end of the selected time interval. Select 1, 1.5, 2-5, or
