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 120 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 Weight: Approx. 157g / 5.54oz1EASY TO INSTALL: Adopt high accuracy temperature and humidity measurement unit, long term stability, small size, wall mounted, rail mounted 2COMMUNICATION: Using dedicated 485 circuit, standard RTU communication protocol, communication address and baud rate can be set 3BASIC SPECIFICATIONS: 10~30V wide voltage range power supply, the output signal type is RS485, the longest communication is 2000 meters 4PROTECTION GRADE: Industrial wall mounted high protection grade housing, protection grade IP65, rain and snow protection and good air permeability 5ADVANCED CHIP: The circuit adopts industrial grade microprocessor chip and imported temperature and humidity sensor to ensure excellent reliability, and interchangeability 2 x Screw 2 x Expansion Tube 1 x Temperature Humidity Sensor 1 x User Manual
