APPendix E：Communication program description
String Communication Protocol Description
| Communication data | Fuction | Data specification |
|---|---|---|
| “fxxx” | Control Frequency | Set the frequency to XXX, for example, F1000, set the frequency to 1K |
| “w1” | Control waveform | The control waveform is sine wave |
| “w2” | Control waveform | The control waveform is triangle wave |
| “w3” | Control waveform | The control waveform is square wave |
| “s1” | save settings | Save the frequency and waveform data to the lower computer. By default, the saved frequency and waveform data are used for power-on |
| “c” | Communication switch | Switch the communication protocol to Modbus |
