How to operate instruments with 485 signals
Thread Content
I have always used analog meters; now I need to work with 485 signal meters, but I have no experience with them. I would like to ask everyone how to configure them. The product is a pressure transmitter that does not come with a display. I see that customers usually use it on their laptops by connecting a cable; what kind of cable is that? Is special software required? As I understand it, it should be possible to set the address of the device using a computer, so that the instrument’s information can be viewed on the computer
A communication line, specialized software, and the cooperation of the equipment manufacturer are required. In fact, you just need to turn to the equipment supplier, and he will take care of everything for you.
Serial communication at 485 uses two wires, A+ and B-, and a USB/485 converter is required when connecting to a laptop. To display the pressure value directly, software is required; if the communication protocol is known, data can be read using a serial port debugging tool.
