READ or WRITE
A write to this register sets the analog input range for all 8/16 analog inputs. The lower three bits set the analog input
range (Table 3-4). The upper five bits are not used.
To set the analog input range of the CIO-DAS16Jr/16 programmatically, write the correct input range code to the base
address + 11. For example, from BASIC:
If the board's base address is 300h (768 decimal), then the gain register is at 768 + 11 = 779
OUT 779, 5 'Set analog output range to 0 to 5V
The decimal range codes are in the far right column above.
