The format of conversion data are binary value and complement binary. The relationship between the voltage of binary value and conversion data is expressed by the following formula.

Voltage value = Binary value X ( Max value of Range - Min value of Range ) / Resolution + Min value of Range

The complement binary is that the conversion data of binary value is handled as 16-bit number and expressed in 2's complement notation. The following table shows the relationship between voltage, binary value and complement binary for the device with (-10 to 10V) range and 12 bit resolution.
