9 New Age Ways To Rs485 Cable > 자유게시판

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. 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. RS-485, also known as ANSI/TIA/EIA-485, TIA/EIA-485 or EIA-485 is a standard used in serial communication systems. It may be used to control video surveillance systems or to interconnect security control panels and devices such as access control card readers.

RS-485 is used as the physical layer underlying many standard and proprietary automation protocols used to implement industrial control systems, including the most common versions of Modbus and Profibus.

It provides a convenient means of connecting the QScreen Controller to a variety of peripheral devices, including analog to digital and digital to analog converters, real time clocks, and other computers which use high speed communication. You’ll find documentation on the manufacturer’s product page including a short datasheet, and a more useful user guide which explains the AT commands set, how to connect to the Things Network, and the method for the firmware upgrade. While the standards bring uniformity to data communications, many areas are not specifically covered and remain as "gray areas" for the user to discover (usually during installation) on his own. Utilizing the downloaded driver, the USB will operate as a virtual Com port, which allows a user to communicate with the RS485 system as a standard PC serial emulation port. Unlike RS232, the RS-485 standard allows for multiple devices to be connected on the same network. While these signals provide a data path, they do not provide hardware handshaking that allows the two communicating parties to let each other know when they are ready to send or receive data. The data transfer that is in process when the write collision occurs is completed.

The Modbus protocol further enables RS485 by allowing a master to send and receive data from specific sensors on the bus or to communicate with all the sensors simultaneously. RS485 is a serial data transmission interface standard that enables communication with sensors attached to the same bus (wires). This cable enables RS485 communication between our EC and MX Smart Sensor boards and development kits and our free GasLab software. For this project, we're using a cheap MODBUS temperature sensor that's probably not suitable for production use, but is good enough for small scale experimentation and learning. Custom FTDI USB - RS485 Cable with Molex connector, fits all GasLab EC and MX Smart Sensor Boards and Development Kits. RS485 Pi at the top of the stack due to the height of the DB9 connector. The RS-485 port can be accessed through the DB9 port or the solder points on the PCB. Without termination resistors, rs485 cable reflections of fast driver edges can cause multiple data edges that can cause data corruption.

The RS485 Pi contains protection against voltage spikes in the form of a TVS Diode and two 10-Ω, Pulse-Proof Thick-Film Resistors. The most widely used protocol is RS232, a full duplex protocol with a single-ended bipolar voltage swing on the serial cable. RS485 is another protocol supported by the primary serial port on the QScreen Controller. Although the maximum standard baud rate of the primary serial port is 19200 baud, nonstandard baud rates of over 80 Kbaud can be attained by the 68HC11's on-chip UART and the onboard RS232 driver. If your application requires RS485, use the primary serial port (serial1) for RS485 communications, and use the secondary serial port (Serial 2) to program and debug your application code using the RS232 protocol.
