#: Save current settings (serial, AIS channel, and debug) as power-on defaults. This is particularly useful
when you want to persist the settings for the NMEA and auxiliary serial output.
ESC: Resume receiving AIS messages.
3.2.2 Debug options
D: Toggles debug messages. When enabled and in AIS receive mode, signal strength and other
information about valid and invalid AIS packets will be displayed. It is normal to receive a lot of broken
packages as there always will be radio noise and ships just out of range. With some experience, you can
use the debug messages to analyze and improve reception issues.
N: Keep pressed to get an idea of the current noise level. -120 to -100 dBm is normal. dAISy will only be
able to receive valid packets roughly 15 dBm above that level, consistent reception 25+ dBm above
noise.
S: If valid packages were received, this gives a summary of the signal strength at which AIS messages
arrived (min, max, average).
T: Enter test mode. In this mode, dAISy outputs a test message every 5 seconds. You can enter your own
message or have it output a preprogrammed AIS message. This mode is useful when you want to test
dAISy but do not have AIS reception at your current location. You can exit test mode by pressing ESC or
power-cycling dAISy.
