The IoT Gateway can realize the bi-directional transparent data transmission between RS-232/RS-485, WiFi, and Ethernet. To understand the working this equipment, read our case study on RS-485 IoT Gateway. You can assign working details, make serial data and TCP/IP data package transparent transfer by the converter, and assign working details via Web Server or setup software with a simple configuration.
The hardware interface of RS-485 consists of,
|Ethernet||1x LAN port|

Well, the RS-485/422/485IoT Gateway allows communication between two devices. One of which could be a computer that's connected via WiFi or Bluetooth, and the other can be any other device with an RS-485 port, such as a sensor, HVAC unit, or even another computer! It's perfect for connecting sensors to your home automation system without the need for Ethernet cabling!
The key benefits of RS-485 over other serial communication methods include its ability to tolerate electrical noise, long cable runs, support for numerous slaves on a single connection, and quick data transmission speeds.
