8. Ground Checks
air
avionics
sitting on the ground, if the simulator is not active, no traffic data is shown. Please
use the simulator function for testing.
We recommend the use of professional ARINC429 analysis tools to check the data interface integrity.
8.2.3 Data Bus Checks
In order to test data bus integrity and bus load, a pragmatic function test of AT-1 connected
to a second bus node can be performed. After at least 20 minutes of continuous operation,
check data validity and correct function by checking and verifying that no errors have been
detected.
We recommend the use of professional CANaerospace analysis tools to check data bus integrity.
8.2.4 WiFi Check
In order to check if the integrated WiFi interface is working, please connect a WiFi capable
device to the AT-1 and check if the data transfer works.
If you want to use the simulator mode in combination with an aviation app for testing,
please proceed as follows:
1. Start the simulator mode on the AT-1 configuration webpage.
2. The data connection to your aviation app does not work while the AT-1 configuration
webpage is open. Close the AT-1 configuration webpage in your web browser.
3. Open your app and test as desired. The simulator will only be active as long as the
AT-1 is running. After the AT-1 has been power cycled, the simulator mode will be
deactivated.
8.3 Discrete Inputs Check
1. For each of the switches that are connected, exercise the switch source.
2. Verify that the function controlled by the switch operates as intended.
3. If the switch is exercised and does not cause the AT-1 to operate as intended, verify
the wiring between the AT-1 and the switch.
8.4 Audio Check
Be careful. Depending on the impedance of your audio system, the test sounds may
be extremely loud. Never test with a headset on your head before having verified
that the volume level is appropriate.
1. AT-1 plays a test sound every time it is switched on. The test sound is either a test
beep or the phrase ‘‘AIR TRAFFIC’’ (if the voice output is activated).
