RS232/RS485 to RJ45 Ethernet Serial Server

This ethernet serial server has dual serial ports with 1-channel RS232 and 1-channel RS485, that is capable of operating simultaneously without interference, all through a single ethernet connection. It packs multiple functionalities in one device, serving as a serial server, Modbus gateway, MQTT gateway, and converter from RS232 and RS485 to JSON, making it a versatile choice for various projects. Powering the device is flexible, with two methods available: a DC port (outer diameter: 5.5mm, inner diameter: 2.1mm) and a screw terminal. The compact case includes rail-mount support for easy installation. This is ideal for projects such as data acquisition, IoT gateway functions, and safety & security IoT. We also have the PoE ethernet version in our store Note: The power supply is not included, it is recommended to use with a 12V Power Adapter Features
