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

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:

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

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.
