Common problems and solutions
The device cannot connect to the PLC or computer
Possible reason：
1) The computer has multiple COM ports and the selected port is incorrect.
2) The device address is wrong, or there are devices with duplicate addresses (the factory default is all 1).
3) The baud rate, check method, data bit, and stop bit are wrong.
4) The host polling interval and waiting response time are too short, and both need to be set above 200ms.
5) The 485 bus is disconnected, or the A and B wires are connected reversely.
6) If the number of equipment is too much or the wiring is too long, power supply should be nearby, add a 485 booster, and add a 120Ω terminal resistance at the same time.
7) The USB to 485 driver is not installed or damaged.
8) Equipment damage.
