Measurement Computing CIO-DAS08-PGH - Manual (Page 20)

There are fewer ranges available for the CIO-DAS08-PGL. Gains of 2, 4 & 8 are often called binary gains. These ranges are not
available on the MetraByte DAS-8PGA.

To set the input range of the CIO-DAS08-PGx board, select the desired range from the table and write the code in decimal or
hexadecimal to base address + 3. Here is an example in BASIC:
100 OUT &H303, 8 'Set gain = 0.5 (±10V range)
The range of the analog inputs is now set to ±10V or 2.44mV per bit (10/4096).
MA2 to MA0 = Indicates the analog input channel that is currently selected (by writing to base +2).
