Baud Rate Synchronization - Waveshare RS485 TO ETH User Manual

RS485 TO ETH
For network speed is faster than serial. Module will put serial data in buffer before sending it to
network. The data will be sent to Network as Package. There are 2 ways to end the package and send
package to network - Time Trigger Mode and Length Trigger Mode.
RS485 TO ETH adopt fixed Package time (four bytes sending time) and fixed Package length (400
bytes).

2.3.4. BAUD RATE SYNCHRONIZATION

When module works with USR devices or software, serial parameter will change dynamically
according to network protocol. Customer can modify serial parameter by sending data conformed
to specific protocol via network. It is temporary, when restart module, the parameters back to original
parameters.
User can adopt Baud Rate Synchronization function by setup software as follows:
