When wiring the 485 signal line, please note that the two lines A\B cannot be reversed, and the addresses of multiple devices on the bus must not conflict. Thread Color Description Power Supply Brown Power Supply Positive (10~30V DC) Black Power Supply Negative Communication Yellow 485-A Blue 485-B Common Problems and Solutions:Equipment cannot be connected to PLC or computerPossible Reason:1) The computer has multiple COM port, and the selected port is incorrect.2) The equipment address is wrong, or there are equipment with duplicate addresses (the factory default is 1).3) Baud rate, check mode, data bit, stop bit error.4) The host's polling interval and waiting time for answering are too short, and both need to be set above 200ms.5) The 485 bus is disconnected, or the A and B lines are reversed.6) If the number of equipment is too large or the wiring is too long, power should be supplied nearby. Add a 485 intensifier and increase 120 terminal resistance.7) The USB to 485 driver is not installed or damaged.8) The equipment is damaged. .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Package List1 x Transmitter1 Bag x Accessories (2 x Screw, 2 x Nut)
