Review on 🌐 USR-M511RS232 RS485 RS422 Ethernet Modbus Gateway with 10/100Mbps Ethernet Interface for Serial to Ethernet Conversion, Modbus RTU/ASCII to Modbus TCP Support, and Modbus Slave Master Support with None/Odd/Even/Mark/Space by Jacob Morrison

This is an excellent product for connecting devices remotely. It offers excellent value for money and is relatively easy to set up. I had to jump through a few hoops replacing a proprietary device that cost nearly three times the price. Once I set it up correctly, it works perfectly. I've been using it for several months with no problems. The documentation is a bit iffy, takes a bit of decoding and reading between the lines, but you'll find what you need with a little digging.
