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)

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.
