This menu includes a function to adjust the Modbus ID number and a screen cleaning function. You can open via the gear in the upper right corner an option menu. Please open this sample in the Arduino IDE. Open the software and change the marked fields as in the picture above. Is it necessary to do the ethernet cable splicing as indicated in the above link, or should I simply be able to use the provided USB cable? Since RS-485 is a multi-point specification, however, this is not necessary or desirable in many cases. The fastest RS-485 transceivers out there right now are running about 50 megabits. Best Offer Weather Station With Rs485 Interface With Cable Length 32 Meter with FREE Shipping Worldwide Now! Initially designed to work with EIG meters, this cable provides a standard RS485 two wire, half duplex interface which will also operate properly with most RS485 systems.

For simple tests a serial connection via USB cable between your PC and the NodeMCU will also work. The SN65HVD72 IC converts the 3.3V UART signals to RS-485 voltages allowing communication with RS-485 compatible devices over a DB9 serial cable or twisted pair cable. Uplink - RS485-LN sends user-defined commands to RS485 devices and get values from the RS485 devices. RS485-LN will process these values and upload the data to the LoRaWAN server. Downlink - RS485-LN runs in LoRaWAN Class C. When the converter receives commands from the LoRaWAN server, it will forward the commands from to RS485 devices connected to it. The interface can be used to support analog to digital and digital to analog converters, networks of many computers controlled by a single master, or networks of devices controlled by several coordinated masters. The data interface solution is owned by Integrated Sports Systems (ISS) Inc. and is licensed to Water Polo Canada. Initially designed to work with EIG meters, the RS485 to USB communication converter cable provides a standard RS485 two wire, half duplex interface which will also operate properly with most RS485 systems. RS485 sensor nodes are often used in smart agriculture, environment monitoring, or factory & building automation and work up to 1.2 km when using AWG 18 cables.

Data translation between different machines can be performed with ease, and applications that communicate via the one serial port can be debugged using the other serial channel. All of the serial ports are supported by pre-coded C-language software drivers that make it easy to exchange data. Multiple function keys make navigation a snap and also allow users to quickly scroll backward to review historical trends. 2. USB - The USB can be a VIRTUAL COM PORT, to make communication a breeze, or USB HID so it can be plug and play for many applications. Stable connections play a crucial role in managing and controlling access to secure areas, optimizing system performance. They are often used for serial connections going to a terminal server in datacentres, rs485 cable for example. The dual communications channels also provide an easy way to link systems that communicate using different serial protocols. In addition to its physical characteristics, RS485 cables also have specific electrical properties that allow for differential signaling, enabling reliable data transmission over longer distances compared to other communication protocols.

Equipment using the RS-485 standard can be used over long distances in noisy environments. RS-485, also known as ANSI/TIA/EIA-485, TIA/EIA-485 or EIA-485 is a standard used in serial communication systems. The E205301 cable is an RS485 to USB serial converter that provides a fast, simple method to connect an EIG power meter with an RS485 interface to a computer with a USB port. The RS485 to USB communication converter provides a fast, simple method to connect an EIG power meter with an RS485 interface to a computer with a USB port. The RS-485 port is connected to the UART port on the Raspberry Pi using a SN65HVD72 interface. Using this cable, you will be able to program a meter, view real time readings and download stored data to a PC using the meter’s RS485 port. The cable easily wires and converts a 2-wire RS485 Shark meter’s input and the 4-wire Unicom 2500 inputs.
