Use:\u003cbr\u003e  1).The Modbus relay module can receive Modbus RTU commands from the host computer\/MCU via the RS485\/TTL UART interface to perform related operations.The following is an example of using the host computer software to open relay 1 (manual mode) through the RS485 interface.Assuming that the device address is 255 and the baud rate is 9600,the steps are as follows:\u003c\/p\u003e\n\u003cp\u003e  2).VCC,GND are respectively connected to the positive and negative poles of the power supply.\u003c\/p\u003e\n\u003cp\u003e  3).A+ and B- are A+ and B- at the output end of the USB to RS485 module respectively.\u003c\/p\u003e\n\u003cp\u003e  4).Open the host computer software \"ModbusRTU Configuration Tool\",select the correct port number,select 9600 for the baud rate,set the address to 255,and click \"Open Serial Port\".\u003c\/p\u003e\n\u003cp\u003e 5).Then click \"JD1 ON\" to turn on relay 1,and the indicator light of relay 1 will be on at the same time.\u003c\/p\u003e\n\u003cp\u003e5.How to Generate Check Code:\u003cbr\u003e  1).When the Modbus RTU command is sent through the ready-made host computer software (such as:ModbusRTU configuration tool),the CRC check code is automatically generated.If you want to use serial debugging software (such as SSCOM) to test the Modbus relay module,you need to manually generate CRC The check code is placed at the end of the sending frame,such as opening the first relay (manual mode):\u003c\/p\u003e\n\u003cp\u003e 2).The sending frame composition of open\/close relay (manual mode) is:Device address (1Byte) + function code (1Byte) + register address (2Byte) + register data (2Byte) + CRC check code (2Byte)\u003c\/p\u003e\n\u003cp\u003e 3).Assuming the device address is 0xFF,the first 6 bytes of the transmitted frame are:FF 05 00 00 FF 00\u003c\/p\u003e\n\u003cp\u003e4).Use the CRC check tool to find the check code for these 6 bytes.\u003c\/p\u003e\n\u003cp\u003e5).After exchanging the high and low byte positions of the check calculation result E499,the CRC check code 99E4 is obtained,and the complete sending frame:FF 05 00 00 FF 00 99 E4.\u003c\/p\u003e\n\u003cp\u003e6).Send
