Application Notes

Dual Transponder Control and Monitoring

Dual transponder control and transponder monitoring via an ARINC 429 data bus is a common aircraft installation. Annunciators are used to report dual transponder status and an ARINC 429 decoder is typically used to provide discrete outputs to illuminate annunciators and advise of transponder status.

Alternating Pulse Lights

This example activates a high intensity pulse light system which is activated by pressing a switch and each light alternates on/off at a frequency of 1 Hz from left to right. Both lights are never on at the same time and when the switch is pressed again, the lights are off.
