MA2 to MA0: Indicate the analog input channel that is currently selected (by writing to base +2).

6.4.1CIO-DAS08-AOH GAIN/RANGES

The gain/range of the board is controlled by writing a control code to the Base + 3 register. The gain/range codes are:

011066+/-0.0051000

0111E14+/-0.01500

001044+/-0.05100

0011C12+/-0.150

CIO-DAS08-AOL GAIN/RANGES

There are fewer ranges available for the CIO-DAS08-AOL. Gains of 2, 4 & 8 are often called binary gains. These

ranges are not available on the MetraByte DAS-8AO. The gain/range of the board is controlled by writing a control code

to the Base + 3 register.
