Bit-mapped parameters
Certain control parameters are defined by bit-mapped values. In order to change these parameters you must
understand how bit mapping works. A bit-mapped parameter is stored as a number, representing a 16-bit
value in the control. If a certain bit needs to be turned on, that bit’s binary value must be added to the
parameter value, if the bit needs turned off, its binary value must be subtracted from the parameter value.
The values for each of the 16 bits’ can be seen in the table below.
Bit-Mapped Parameter Bits

To set bit-mapped parameters simply add together the bit values that you need to have enabled.
