Introduction to the method of online modification of the bau

The purpose of the CAN Ethernet conversion module is to avoid the need for engineers to go to the site because the baud rate will not be set. Engineers can complete the on-site GCAN-202 baud rate setting as long as they are in the office. The following is a simple way to use this function.

 

When the CAN Ethernet conversion module is working normally, the data on both sides of the bus will be forwarded to each other according to specific conversion rules, that is, when a CAN data is forwarded to the Ethernet bus, the data must be 13 bytes, the same as Ethernet Every 13 bytes on the bus will be converted into a piece of CAN data. For example: the Ethernet end sends a piece of data such as 08 00 00 00 01 11 22 33 44 55 66 77 88, which becomes a piece of data after being converted to the CAN bus. ID: 001, data: 11 22 33 44 55 66 77 88 standard data frame.

 

According to the above principle, send instructions on the Ethernet side according to the following instructions to realize the online modification of the baud rate of GCAN-202 (the data in the following table except 1, 2, 3, and 5 are all fixed).
