Wiring Instructions:
Power and 485 Signals
Wide Voltage Power Input 10~30V Can Be Used. 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 Binary
Data Bits: 8 Bits
Parity Bit: None
Stop Bit: 1 Bit
Error Check: CRC (Redundant Cyclic Codes)
Baud Rate: 2400bit/s, 4800bit/s, 9600 bit/s can be set, the factory default is 4800bit/s
Common Problems and Solutions:
The device cannot be connected 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. Baud rate, check mode, data bit, stop bit error
4. The 485 main wire is disconnected, or the A and B lines are reversed
5. If the number of devices is too large or the wiring is too long, power supply should be provided nearby, 485 boost should be added, and 120Ω terminal resistance should be added at the same time
6. The USB to 485 driver is not installed or damaged
7. The equipment is damaged
