How RS485 Works and how to Implement RS485 > 자유게시판

SenseCAP Data Logger and IoT Platform Compatible: Convert to a SenseCAP LoRaWAN® sensor with SenseCAP Data Logger and take advantage of quick and easy set-up in just 5 minutes with SenseCAP Mate APP. Each device has a communication port with two terminals, which are indicated for the sake of convenience as A and B. In these two terminals the communication cable is connected so that all the devices that take part in the communication are connected in parallel. This makes it ideal for connecting devices in geographically dispersed locations. It is unquestionably an ideal choice for industrial equipment use due to its high speed, reliability, safety and versatility. It is also an ideal choice for industrial equipment use due to its high speed, reliability and safety. The cost-effectiveness, compatibility, and versatility of RS485 make it a go-to solution, minimizing wiring and relay equipment costs. The maximum RS485 cable length is typically listed as 1200 meters or about 4000 feet.

For example, if the data rate is 100 kbps, the maximum cable length is 4000 feet. We also see that there is a maximum slew rate defined for both RS232 and RS423. Differential signals and twisting allows RS485 to communicate over much longer communication distances than achievable with RS232. RS485 can handle up to 32 connected devices. You can easily enjoy the advantages such as low power consumption and long transmission range, without affording the cost of changing the sensors you are using. It also features embedded circuits protection features such as power isolation, ADI magnetical isolation, and TVS diode. It has anti-ultraviolet and anti-rain features as well, what is rs485 cable making it suitable for long-term outdoor use. Clueing in from its name, this is a USB to RS485 converter with industrial-grade features. Just like it’s older brother RS232, RS485 is a form of serial communication. Both RS232 and RS485 are good for short-distance serial communication. RS485 Transceiver: This is the fundamental building block of any RS 485 network.

When using the default RS485 receivers with an input resistance of 12 kΩ it is possible to connect 32 devices to the network. Data transmission speed: RS485 supports data transmission speeds of up to 10 Mbps, depending on the cable length and other factors. Their main difference boils down to one having only support for RS485, while the other one supports RS232 and TTL as well. This standard supports multipoint communication, allowing several devices to connect to the same bus and communicate with each other. Each protocol has its own specifications and characteristics, meeting specific requirements of different devices and applications. Our range of IIoT products is wide, with different sensors and hubs for different scenarios and requirements. With best-in-class IIoT solutions constructed with premium products and services, Seeed aims to serve smart agriculture, smart weather stations, smart cities, and other environmental-sensing scenarios. It is made up of hardware products (sensors, data loggers, and gateways, for example), software services (SenseCAP portal, mobile App, open dashboard), and an API for system and data management.

928MHz), different gateways, and LoRaWAN network servers. SenseCAP S2100 data logger can collect data from multiple sensors and transfer the data through the LoRaWAN network. This is an Industrial-grade 4G Data Logger from the Seeed’s SenseCAP product series. Grove sensors to MODBUS RS485 industrial-grade sensors. Think of RS485 as the younger, faster brother of RS232. First of all we see that the speed of the differential interfaces RS422 and RS485 is far superior to the single ended versions RS232 and RS423. If on the other hand each terminal can accept only a single cable, a proper branch must be created using three auxiliary terminals for each instrument to be connected. What made it such an advancement over RS232 was the fact that it could transmit not only a single device to device transmission, but also a communications bus to connect multiple devices at once. It is commonly used in industrial and commercial settings where there is a need to connect devices over long distances.
