UA20-E ｜Data collector via RS-485

Introducing the UA485-E, an industrial master device that easily collects RS-20 sensor data via USB.

The UA20-E is a transmitter that reliably receives data from various sensors and control devices based on RS-485 (Modbus RTU) and can be easily connected to PCs, control systems, and Cloud Serivce-linked devices via a USB interface.

UA20-E Key Features

✔ Supports 6-channel RS-485 (Modbus RTU) input

Up to 6 Modbus RTU output sensors can be connected independently, and data can be collected by individually setting the Holding Register address for each channel.

✔ Adoption of RS-485 Master communication method

UA20-E is an RS-485 Master device that requests data from connected sensors or PLCs, such as slave devices, and receives responses. It is configured in a two-wire half-duplex manner, enabling stable communication even in multi-node environments in industrial sites.

✔ USB CDC output & compatible with various operating systems

The collected data is transmitted via USB and is automatically recognized as a virtual COM port in Windows, Linux, and MacOS environments for easy connection.

✔ Includes Tapaculo Lite monitoring software

Tapaculo Lite (for PC) supports real-time monitoring of up to 128 channels and provides an efficient data collection environment by linking with various Radionode devices including UA20-E.

✔ Supports Cloud Serivce transmission when connected with RN17Xplus transmitter

UA20-E can be used with RN171 (Ethernet), RN172 (WiFi), RN173 (LoRa) to upload real-time data to the Radionode365 Cloud Serivce platform.

✔ Easy setup with dedicated software

UA20-E can intuitively perform Modbus settings and data calibration for each channel through dedicated configuration software, Radionode Calibrator. Users can easily adjust the following settings in a GUI-based environment, and the software can be downloaded for free from the Radionode homepage.

  * Setting Modbus parameters such as Slave ID / Function Code / Start Address etc.

  * Set data type (Float/INT) and unit conversion (Division)

  * Real-time collection value verification and sensor calibration

  * Check channel-specific settings status and response (TX/RX LED support)

  * RESET function and usage history check

UA20-E is recommended for these places

● Building an IoT environment data collection system

● Real-time equipment monitoring in smart factories

● Automating data logging for control systems (PLC, etc.)

● Cloud-based sensor network integration
