The LED Command
The Key Croc features a multi-color LED which is controlled using the LED Command. This may be useful in payloads for debugging or other specialized purposes. Otherwise, considering the covert nature of the device the LED is typically off.
LED COLORS
| COMMAND | Description |
|---|---|
| R | Red |
| G | Green |
| B | Blue |
| Y | Yellow (AKA as Amber) |
| C | Cyan (AKA Light Blue) |
| M | Magenta (AKA Violet or Purple) |
| W | White |
While the LED may be manually set to any of the above colors, it is highly recommend that payloads conform to one of the LED States listed below.
