How to use the converter?

1, network cable interface (as shown in the figure). You can plug the network cable into the network cable interface. This is very important because the usb cable converter is only used for conversion.

2.usb plug. Plug the usb cable converter connected to the network cable into the computer to surf the Internet.

3. Connect the network cable plug to the network cable interface, and pay attention to whether the network cable interface matches the network cable. As shown in the figure.

4. Then connect the usb cable converter to the computer, and pay attention to the usb interface.

Principle:

The principle is to first convert the input analog signal into frequency, and then use the counter to convert the frequency into digital quantity. Theoretically, the resolution of this kind of AD can be improved almost infinitely, as long as the sampling time can meet the width of the cumulative pulse number required by the output frequency resolution. Its advantages are high resolution, low power consumption and low price, but external counting circuit is needed to complete AD conversion.
