Setting The Conversion Conditions - Contec DA16-16L User Manual

4. Functions

1. Setting the Conversion Conditions

First, set the conditions for executing analog output.
Resolution
"Resolution" signifies the number of bits used by an analog output device to represent analog signals.
The higher the resolution, the more finely the voltage range is segmented, allowing the device to
convert digital values to analog equivalents more precisely.
A device with a resolution of 12bit divides the range width into 4096 segments.
When the device covers the range of 0 - 10V, the minimum unit of converted voltages is
10÷4096 ≈ 2.44mV.
If the device has a resolution of 16bit, it is 10 ÷ 65536 ≈ 0.153mV instead.

Channel
"Channel" represents each point of analog output.
For individual channel numbers, see "How to connect the connectors" to "Connector Pin Assignment"
in Chapter 3 "External Connection".
You can specify an arbitrary number of points of analog output by setting the channels by means of
software.
Range
"Range" means the range of voltages at which analog output can be performed.
Software setup of the range is not required as this product uses a fixed range of voltages.
