Communication Protocol

A communication protocol can just like a language. If you want to communicate, you must have the same language. Sunyuan Technology products have two communication protocols to choose from, namely character protocol and RTU protocol. Which protocol is configured, you must select the corresponding communication protocol.

Case: The customer reported that the data cannot be saved after the product is configured and powered on again. After checking, the customer chose to set the communication as RTU protocol after the character protocol was configured. As a result, there was no reply during the serial port software test. This is the phenomenon that some users often report that the protocol is configured and then tested but there is no reply.
