2 Analog Output Module DVP02DA-E2/DVP04DA-E2
2.6.3 Explanation on Special Registers D9900~D9999
When ES2 MPU is connected with modules, registers D9900~D9999 will be reserved for storing values from
modules. You can apply MOV instruction to operate values in D9900~D9999.
When ES2 MPU is connected with DVP04AD-E2, the configuration of special registers is as below:

2.7 D/A Conversion Curve
You can adjust the conversion curves according to the actual needs by changing the Offset value (CR#28 ~ CR#31)
and Gain value (CR#34 ~ CR#37).
Gain (in DVP02/04DA-E2): The corresponding voltage (current) output value when the digital input value = 16,000.
Offset (in DVP02/04DA-E2): The corresponding voltage (current) output value when the digital input value = 0.
