Base PoE is an M5 Base that implements a W5500 Ethernet controller chip with PoE module, which provides Hardwired TCP/IP embedded Ethernet control to facilitate easier internet connection to embedded systems. W5500 integrates TCP/IP protocol stack, 10/100M Ethernet data link layer (MAC) and physical layer (PHY).This base supports RS485 / RS232 communication and can be used as an Ethernet to serial port server. It is specifically designed for industrial applications. PoE (Power over Ethernet) technology is supported. Through the built-in PoE module, power can be directly supplied to the base through PoE hub / switch without a separate power supply. It comes with a couple of HT3.96 connectors, metal rail and magnet discs for easy installation. The 6 pins of the HT3.96 connector are spare, you can wire them up with an RS485 or RS232 adapter board as you like.
The figure below shows the internals of the LAN base
If you need to add an RS485 or RS232 interface, make sure to solder the RS485 or RS232 board onto the main board pin correspondingly.
