Sending requires the customer to calculate the CRC value by himself. <br>Method 2: Know the current station number and send the following command <br>02 06 10 00 00 03 CD 38 Its function is to change the station number from No. 2 to No. 3. <br>Note: Replace the italicized characters with the original station number, and replace the regular characters with the value of the target station number that you want to modify. Sending requires the customer to calculate the CRC value by himself. <br>Method 3: Forget the original station number, you need to connect the product to the computer alone, pay attention <br>There can be no other 485 products on the bus. Use station 0 to operate them. The instructions are as follows: 00 10 10 00 00 01 02 00 03 FA 00 <br>Note: The big characters are the target station number value
