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.
AO-1604LX-USB
: The resolution is 16bit.
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 board uses a fixed range of voltages.
AO-1604LX-USB
: The output range of the device is set by software.
