Provides PWM and analog gain for the color channels. The range will vary based on scan mode. The device specific POS should describe the valid range. The format is the following: PWM value; red analog gain; green analog gain; blue analog gain. Additional information: The range will vary based on scan mode. The values will differ from those of San Diego. The initial value can be obtained at the start of warmup and the final value can be obtained at the end of warmup. The warmup period is about 2 minutes. The format is the following PWM value; red analog gain; green analog gain; blue analog gain;. The valid values for PWM value are 580 - 730 and the valid values for analog gains are 1.00-5.80. The gains are reported with accuracy to 2 decimal places. A sample return value would be '584;1.00;1.34;1.00;'
