Test

Connect the serial port of USR-G786-G to the computer via a serial to USB cable, Modbus RTU data sent by the

serial port is converted into MODBUS TCP data by G786-G and then sent to the network side. Similarly, G786-G
converts the MODBUS TCP data on the network side into MODBUS RTU data and transmits it to the serial port.

6.5. FTP Upgrade
