Features1Integrated design, it uses multiple acquisition devices integrated design, built?in electronic compass, no direction requirements, can be installed horizontally, convenient and simple. 2Ultrasonic principle measurement, it has no angle limit, 360 degrees can obtain omnidirectional wind speed and wind direction data at the same time, and can also be used for noise collection, with a range of up to 30dB~120dB. 3Using dedicated 485 circuit, it has stable communication, convenient to measure the environmental temperature and humidity, the measurement unit is imported from Switzerland, and the measurement is accurate. 4It is widely used in various situations that need to measure environmental temperature and humidity, noise, etc. 5Small size and light weight, it is made of high?quality materials, has a long service life, high probe sensitivity, stability and reliability, and has the characteristics of wide measurement range, good linearity, good waterproof performance, and long transmission distance.SpecificationItem Type: Temperature and Humidity DetectorProduct Size: Approx. 21x10.5cm / 8.3x4.1inModel: RS-FSXCS-N01-3Name: Small 485 Ultrasonic Integrated Weather StationPower Supply: DC 10-30VFunction: Ultrasonic Wind Speed And Direction + Shutter Box + Temperature and Humidity and Other Functions.Weight: Approx. 619g / 21.8ozMaterial: ABSPower Interface: DC Power Supply 10-30V Power Supply.When using the RTU communication protocol, the format is as follows:Initial Structure: 4 Bytes Of TimeAddress Code: = 1 ByteFunction Code: =1 ByteData Area: =N BytesError Check: = 16-Bit CRC CodeEnd Time Structure: 4 BytesAddress Code: the start address of the transmitter, which is unique in the communication network. (Factory Default 0x01).Function Code: Command function instruction issued by the host, this transmitter only uses function code 0x03. (Read Register Data).Data Area: The data area is the specific communication data. First, pay attention to the high byte of the 16-bit data.CRC Code: Double-Byte Check Code.RS-Company CodeFSXCS-Ultrasonic Comprehensive Weather StationN01-485 Communication (Standard RTU Protocol)3-Small Ultrasonic Integrated ShellBasic ParameterMaximum Power ConsumptionRS485 Output0.7WAccuracyWind Speed0.5+2%FSWind Direction3 DegreeHumidity3%RH(60%RH,25)Temperature0.5 DegreeC (25 DegreeC)RangeWind Speed0~40m/s, the initial wind speed is 0.5m/s.Wind Direction0~359 DegreeHumidity0%RH~99%RHTemperature-40~+80Long-Term StabilityTemperature0.1/yHumidity1%/yResponse TimeWind Speed1SWind Direction1STemperature And Humidity1sOptical Rainfall ParametersAccuracy5%Resolution0.1mmMaximum Instantaneous Rainfall24mm/minRain Trail6cmProtection LevelIP54Basic Communication ParametersCode8-Bit BinaryData Bit8-BitParity BitNot SupportStop Bit1 DigitError CheckingCrc (Redundant Cyclic Code)Baud RateCan be set to 2400bit/s, 4800bit/s, 9600bit/s, the factory default is 4800bit/s.Slave Response Frame StructureAddress CodeFunction CodeNumber Of Valid BytesData AreaData Area TwoData N AreaCheck Code Low ByteCheck Code High Byte1bit1bit1bit2bit2bit2bit1bit1bitHost Query Frame StructureAddress CodeFunction CodeRegister Start AddressRegister LengthCheck Code Low ByteCheck Code High Byte1bit1bit2bit2bit1bit1bitCommon Problems and Solutions:The possible reasons when the device cannot be connected to the PLC or computer are as follows: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 value is 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 reversed.6. If there are too many devices or too long wiring, power should be supplied nearby, add 485 boost, add 120 and measure the terminal resistance at the same time.7. The USB to 485 driver is not installed or damaged.8. The equipment is damaged.Package List1 x Weather Equipment Product 1 x Accessory Kit (3 x Screws,6 x Nut) 1 x Connection Line 1 x English Manual 1 x Accessory Board
