Flash Patterns

Each object uses a 32-step Flash Pattern that you can define so you can identify an active object at a glance from across the room. Flash patterns are defined in the Edit Objects Menu (see “Editing Objects” on page 29.).

Each step in the 32-step flash pattern defines whether the backlight is on or off for the durations specified in the “On Time” and “Off Time” settings for the object. The 32-step Flash Pattern consists of eight blocks with four steps for each block. The flash pattern within a four step block is defined using the characters 0-9 and A-F. The flash patterns for each four step block are:

0:				
1:				
2:				
3:				
4:				
5:				
6:				
7:				
8:				
9:				
A:				
B:				
C:				
D:				
E:				
F:				

=ON, =OFF

The flash pattern is set for each block by specifying the number or letter associated with the desired flash pattern. Using this technique it is possible to define simple or complex flash patterns.

“On Time” and “Off Time” control the backlight on and backlight off duration for each of the 32 steps in the flash pattern. On Time and Off Time are specified in 10 millisecond increments. For example, an On Time of 50 means the light will come on for 500 milliseconds (or one-half second) for each flash pattern step where the light is set to on.

There are many different possible flash patterns possible with this feature. Here are a few that you can use to get started:

Flash pattern: 55555555, On Time: 50, Off Time: 50

These are the default values for flash pattern, On Time and Off Time. When the object is active, the LED backlight will flash on and off at a rate of one flash per second, with each flash lasting half a second.

Flash pattern: 88888888, On Time: 50, Off Time: 50

This combination causes the LED backlight to come on for a half second every two seconds.

Flash pattern: A8A8A8A8, On Time: 1, Off Time: 5

This combination creates an interesting “strobe light” effect similar to the emergency lights on a public safety vehicle.

Many more combinations are possible—you can experiment to find the ones that work for you.
