Three.Usage method
The followingWIN10 64bit system is introduced as an example.
1.Hardware preparation
1.1 DC power supply(Not include):
7~24V, 100mA above
1.2 RS485 converter(Not include):
Prepare a good quality.RS485 converter (preferably active RS485 converter), or other hardware with RS485 interface (touch screen, PLC, industrial computer or customer development hardware equipment), USB to RS485 converter or RS232 to RS485 converter can be, must ensure that the converter can send and receive data in two directions, some monitoring converter is single It is impossible to use communication. When buying, you must ask the seller clearly.
One point threeDownload correspondingRS485If the driver of the converter is installed properly, make sure that the driver is installed correctly and that there is no yellow exclamation mark in front of the installed driver.
