Pilot LEDs

All Pilot devices have activity LEDs. The simplest description is that a 1Hz flashing green LED means the device is running, 4Hz that it is booting/programming. Red is used to indicate how many wireless devices are connected.

Pilot-CAN

The Pilot-CAN has two LEDs but only one "light pipe" to see them. So when both red and green are on will appear orange/yellow. You should look at the LED straight on to see both but you can view at oblique angles to help seeing green or red separately. If you find it difficult to see the LED (because it is mounted out of sight), then consider adding serial number outputs etc to the config to better indicate status.

Pilot-MUX

The Pilot-MUX has a secondary (alternative) LED set to report details of the expansion radio communications. There are three LED indicators: a green CPU light, a main activity indicator which can illuminate red or yellow (or a combination of red and yellow) and an alternative activity indicator which can also illuminate red/yellow.

*for Pilot-DAC variants the ALT Activity light is flashed to signify that the analogue converter is running. More complex patterns are not supported in this mode.

LED Numeric Flash Codes

So that a single LED can express more than just on/off, the Pilot flashes the LEDs according to the following table to indicate numeric values. The repeat speed is 1Hz. i.e. to signal "1" the LED flashes at 1Hz. To signal "2" it does two short flashes (100mS, spaced 100mS) each second. Low numbers (by far the most common use case) are easy to read; higher numbers (where it is normally the case you may be logging the information) can be captured with a phone on "slow-mo"!
