Indicator LED’s
There are two indicator LEDs on the 4/8/16 Keystick. The green LED will be on by default when the device is
powered. By default, the red LED is used to indicate the alternate red device layer, to create a visual reference
for the current layer. The LEDs can be manipulated in either software or hardware mode and both LEDs are
also capable of flashing autonomously.
Programming Button
The programming switch is located on the left side edge of the 4/8/16 Keystick. The program switch will display
the MacroWorks GUI by default. If desired, the program switch can be used like any other key on the RCK-
Keystick, effectively making it a 25 button device.
