Communication Protocol

The product uses RS485 MODBUS RTU standard protocol format, all operation or reply commands are

hexadecimal data. The default device address is 1 when the device is shipped, the default baud rate is 9600, 8, n,

For the correct query frame, the devi ce will respond with data:01 03 06 00 7B 00 00 00 00 C5 7F , the response

format is parsed as follows:

Read and modify device address

Device ID Function id Start Address Data Length CRC16

FA 03 00 64 00 02 90 5F

Read or query device address

If you don’t know the c urrent device address and there is only one device on the bus, you can use the command

FA 03 00 64 00 02 90 5F Query device address.

FA is 250 for the general address. When you don’t know the address, you can use 250 to get the real device

address, 00 64 is the device model register. For the correct query command, the device will respond, for example

the response data is: 01 03 02 07 12 3A 79, the format of which is as shown in the following table:

Device ID Function id Start Address Model Code CRC16

01 03 02 55 3C 00 01 3A 79

Change device address

For example, if the current device address is 1, we want to change to 02, the command is:01 06 00 66 00 02 E8 14

Device ID Function id Start Address Destination CRC16

Read and Modify Baud Rate

Read baud rate

The device default factory baud rate is 9600. If you need to change it, you can change it according to the following

table and the corresponding communication protocol . For example, read the current device’s baud rate ID, the

command is:01 03 00 67 00 01 35 D5 , its format is parsed as follows. Read the baud rate encoding of the current

devic e. Baud rate encoding: 1 is 2400; 2 is 4800; 3 is 9600; 4 is 19200; 5 is 38400; 6 is 115200.

For the correct query command, the device will respond, for example the response data is: 01 03 02 00 03 F8 45,

the format of which is as shown in the followin g table:

Device ID Function id Start Address Data Length CRC16

01 03 00 67 00 01 35 D5

Change the baud rate

For example, changing the baud rate from 9600 to 38400 , ie changing the code from 3 to 5, the command is: 01

06 00 67 00 05 F8 1601 03 00 66 00 01 64 15 .

Read Correction Value

When there is an error between the data and the reference standard, we can reduce the display error by adjusting

the correction value. The correction diﬀerence can be modiﬁed to be plus or minus 1000, t hat is, the value range

is 0 1000 or 64535 65535. For example, when the display value is too small, we can correct it by adding 100. The

command is: 01 03 00 6B 00 01 F5 D6 . In the command 100 is hex 0x64 If you need to reduce, you can set a

negative val ue, such as 100, corresponding to the hexadecimal value of FF 9C, which is calculated as 100

65535=65435, and then converted to hexadecimal to 0x FF 9C. The correction value starts from 00 6B. We take

the ﬁrst parameter as an example. The correction valu e is read and modiﬁed in the same way for multiple

parameters.

For the correct query command, the device will respond, for example the response data is: 01 03 02 00 64 B9 AF,

the format of which is as shown in the following table:

Device ID Function id Data Length Data value CRC16

01 03 02 00 64 B9 AF

Change correction value

Fo r example, the current state quantity is too small, we want to add 1 to its true value, and the current value plus

100 correction operation command is:01 06 00 6B 00 64 F9 FD .
