It converts a USB port to use with RS485. This converter converts a USB port to not only RS485 but also RS232 and TTL, making it more versatile. By adding another 2 wires, making it a 4 wires system, it allows data transmission in both directions to and fro devices at the same time, also known as full-duplex. The twisted pairs in RS485 give immunity against electrical noise, making RS485 viable in electrically noisy environments. RS485 is however most popularly used in programmable logic controllers and factory floors where there are lots of electrical noise. However, in a full-duplex setup, they are limited to a master and slave communication where slaves cannot communicate with each other. In this setup both the TX and RX share a single pair of wires, therefore it is https://www.thesaurus.com/browse/limited">limited to half-duplex data transmission as the data cannot be transmitted simultaneously to and fro each device.

In RS485 standard, data is transmitted via two wires twisted together also referred to as "Twisted Pair Cable". RS485 main advantages as compared to other serial communication are tolerance to electrical noise, lengthy cable runs, multiple slaves in one connection, and fast data transmission speed. This is especially important in those industries where there are high quality requirements to the equipment being produced. Star and ring topologies are not recommended because of signal reflections or excessively low or high termination impedance. In three-phase systems with distributed neutral three current transformers are required. It is commonly implemented to control video surveillance systems and link security control panels to https://www.wonderhowto.com/search/devices/">devices such as access control card readers. RS485 is used as the physical layer for many standards and proprietary automation protocols to implement control systems, most commonly Modbus. In computer systems, RS485 is used for data transmission between the controller and a disk drive. This is due to the minimal wiring required due to the wiring configuration requirements of RS485. It is also an ideal choice for industrial equipment use due to its high speed, reliability and safety. RS485 transmits binary signals by generating high and low voltages, representing binary 0s and 1s (on and off), enabling efficient long-distance communication in electronically noisy environments.

It is unquestionably an ideal choice for industrial equipment use due to its high speed, reliability, safety and versatility. Most Modbus implementations use RS485 due to the allowance of longer distances, higher speeds and multiple devices on a single network. The other devices (the slaves) respond by giving the requested data to the master, or by taking the action requested in the query. Up to 32 slaves can be connected in the system. Easy to Use: The sensor can be used out-of-box through Bluetooth configuration, and users receive the data on the phone, cloud servers, and different platforms in just a few clicks. Supports Third-party Data Loggers and IoT Platforms: Besides SenseCAP Data Logger, developers could connect to other data loggers that support MODBUS RS485 protocol and third-party IoT platforms. 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. Another major advantage is that there can be more than one slave in the connection. This is great for Supervisory Control and Data Acquisition (SCADA) systems where there are many devices and it also comes at a very low cost to implement.

RS485 is also commonly used for building automation as the simple wiring configuration and lengthy cable length are ideal for joining remote devices. If you ever wanted to connect to device in the same building (e.g. to machinery on production hal) and to you have to go to it to connect your computer. Variably, this time both TX and RX have their own 2 wires for data transmission. It has Max.10 year of battery life and can cover a transmission range of 2km in urban scenes and 10km in line-of-sight scenes. LoRaWAN Wireless Transmission: Ultra-low power consumption and ultra-wide-distance transmission range. Compatible with Worldwide LoRaWAN networks: It can be used with different types of LoRaWAN gateways and is compatible with multiple LoRaWAN Network Servers (Helium, TTN, etc). SenseCAP S2100 data logger can collect data from multiple sensors and transfer the data through the LoRaWAN network. Powerful APP Support: SenseCAP Mate APP allows you to set the sensor templates and quickly turn the data logger into the sensor you want. RS485 at its core with 2 wires allows half-duplex data transmission.
