This PoE 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 great choice for various projects. It is equipped with dual ethernet ports, both of which support the Power over Ethernet (PoE) function. This eliminates the need for separate power supplies and outlets and offersexpanded options for how and where ethernet end devices can be placed.

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 our standard RJ45 ethernet version here

Note: The power supply is not included, it is recommended to use with a 12V Power Adapter
