When Wiring The 485 signal line, pay attention that the 2 lines A and B cannot be reversed, and the addresses of multiple devices on the bus cannot be conflicted. (Note: The device does not provide a communication line by default)Basic Communication Parameters: Encoding: 8bit BinaryData Bits: 8 BitsParity Bit: NoneStop Bit: 1 BitError Check: CRC (Redundant Cyclic Codes)Baud Rate: 2400bit/s, 4800bit/s, 9600 bit/s can be set, the factory default is 4800bit/sCommon Problems and Solutions: The device cannot be connected to the PLC or computerPossible Reason: 1. The computer has multiple COM ports, and the selected port is incorrect2. The device address is wrong, or there are devices with duplicate addresses (The factory default is all 1)3. Baud rate, check mode, data bit, stop bit error4. The 485 main wire is disconnected, or the A and B lines are reversed5. If the number of devices is too large or the wiring is too long, power supply should be provided nearby, 485 boostshould be added, and 120 terminal resistance should be added at the same time6. The USB to 485 driver is not installed or damaged7. The equipment is damagedWeight: Approx. 157g / 5.54oz
