ICAP_BRIGHTNESS

Description

The brightness values available within the Source.

Application

The application can use this capability to inquire, set, or restrict the values for BRIGHTNESS used in the Source.

Source

Values

Source should normalize the values into the range. Make sure that a ‘0’ value is available as the Current Value when the Source starts up. If the Source’s ± range is asymmetric about the ‘0’ value, set range maxima to ±1000 and scale homogeneously from the ‘0’ value in each direction. This will yield a positive range whose step size differs from the negative range’s step size.
