LED Script

The LED script describes the color and blinking pattern of a Line Key LED. Each script contains a number of fields separated by a semicolon(;). White spaces are ignored. Each field has the syntax < field-name > = < field-value >. The allowed field-name and corresponding field-values are listed below:

c=o|r|g|a
 

This field sets the color of the LED. The 4 choices are:

  • o = off
  • r = red
  • g = green
  • a = amber (orange)
p=n[b]|s[b]|f[b]|u[d]
 

This field sets the blinking pattern of the LED. The 4 choices are:

  • nb = no blink (steady on or off)
  • sb = slow blink (1s on and 1s off)
  • fb = fast blink (100ms on and 100ms off)
  • ud = user-defined (according to the contents of the u field)
u=on/off/on/off/etc.
 

This is a user-defined blinking pattern used only when p = ud. It consists of up to 4 pairs of on/off duration in seconds with up to 2 decimal places; each value is separated by a forward slash (/).

LED Script Examples

c=o

c=a;p=ud;u=.1/.1/.1/.1/.1/.9
 

Color is amber (orange) and the blink pattern is: 100ms on, 100ms off, 100ms on, 100ms off, 100ms on, 900ms off.
