FAQs：
Air pressure sensor cannot be connected to PLC or computer
Possible causes:
1, the computer has more than one COM port, select the wrong port.
2, air pressure sensor address is not correct, or there is a duplicate device address (all factory default is 1).
3, baud rate, check mode, data bit, stop bit error.
4. The host polling interval and waiting response time are too short. Set them to more than 200ms.
5. The 485 bus is disconnected, or the A and B wires are connected in reverse.
6, if the number of air pressure sensor is too much or the connection is too long, should be the nearest power supply, add 485 intensifier, increase the resistance of 120Ω end.
7. The USB to 485 driver is not installed or damaged.
8. Equipment damage.
