II. Send and receive
7. Configure the display mode of sending and receiving data; set to "HEX" display mode;
8. After configuring the above functions, open the serial port;
9. Enter the corresponding request message in the sending window, and the CRC will be automatically added;
10. Click Send to display the corresponding data in the receiving window;
Send the corresponding request message according to the communication protocol to obtain the corresponding
measurement or setting data. If you need to read the phase A voltage, you can use the following message to
access, as shown in the figure below.
1. Window 1 is the sending message input window; enter the requested message in this window,
note that the CRC is automatically added;
2. Window 2 is the message display window; the complete message received and sent is displayed in this
window: the green line is the request message sent by the master, and the blue line is the response
message returned by the slave.

COMMIX software instructions
1. Configure commix software
Figure 1
Figure 2
1. Set the serial port to be same as your computer; Example: set it to "COM1" if my computer's serial port is COM1.
2. Configure the baud rate; configure the corresponding baud rate according to the baud rate set by the meter,
such as 9600
3. Configure communication data bits; the default is 8 bits.
4. Configure the parity bit; the default is no parity, you can set "even parity" and "odd parity"
5. Configure stop bit; default 1 stop bit
6. Set the data verification mode; set to MODBUS-RTU verification mode, as shown in Figure 2.
