3.5.2 Spectrum Spreader
OP6800 operator interfaces that carry the CE mark on their RabbitCore module have a
Rabbit 2000 microprocessor that features a spectrum spreader, which helps to mitigate
EMI problems. By default, the spectrum spreader is on automatically for OP6800 operator
control panels that carry the CE mark when used with Dynamic C 7.30 or later versions,
but the spectrum spreader may also be turned off or set to a stronger setting. The means for
doing so is through a simple global macro as shown below.
There is no spectrum spreader functionality for OP6800 operator control panels that do
not carry the CE mark on their RabbitCore module or when using any OP6800 with a
version of Dynamic C prior to 7.30.
1. Select the “Defines” tab from the Dynamic C Options > Project Options menu.
2. Normal spreading is the default, and usually no entry is needed. If you need to specify
normal spreading, add the line
ENABLE_SPREADER=1
For strong spreading, add the line
ENABLE_SPREADER=2
To disable the spectrum spreader, add the line
ENABLE_SPREADER=0
NOTE: The strong spectrum-spreading setting is not needed for the OP6800.
3. Click OK to save the macro. The spectrum spreader will now remain off whenever you
are in the project file where you defined the macro.
