🚀 Connect Smarter, Work Faster: The Ultimate Serial-to-Ethernet Powerhouse
The USR-TCP232-306 is a versatile serial device server featuring a 48MHz ARM Cortex-M0 core and a deeply optimized TCP/IP stack for low latency and high reliability. Supporting RS232, RS485, and RS422 serial interfaces, it converts serial data to Ethernet with Modbus RTU to TCP protocol conversion. Equipped with a 10/100Mbps Ethernet port with Auto MDI/MDIX, it offers easy configuration through a built-in web interface or AT commands. Ideal for industrial automation, smart traffic, and manufacturing, it ensures continuous operation with hardware and software watchdogs that auto-restart the device if needed.

great little serial server
It works just like I expect - it has a web interface to set serial port properties. To send or receive serial data, you connect to it via a TCP socket. And, it's reasonably priced. It comes with a 5V, 1A power supply and a DB9 serial cable. It accepts a wide input voltage so it's easy to power. I also like the terminal blocks to make it easy to hook up RS485 or 422 devices without needing to custom wire a D-sub connector. The configuration website is a little hard to decipher because the defaults don't seem to be a functional configuration. I set the "Work Mode" to TCP Server, and then set the "Local Port Number" to the port number, and was able to open a socket and communicate. Supposing you had a modem attached to the serial port, and configured the Local Port Number to 3000: import socket s = socket.socket() s.connect(('192.168.0.7', 3000)) s.send(b'AT\r\n') data = s.recv(1024) # should be b"OK" It has some other operating modes (UDP, etc). There are manuals on the manufacturer's website. I'm planning to use it to speak RS485 to my water heater's data port, so I can track temperature and power usage.

Versatile for serial connections.
This device is a flexible and versatile connection to serial devices, and it well suited to experimentation. Although my early attempts to interface it to serial gear have not yet been successful, I am still willing to give this item a high rating owing to its versatile array of connection options, it’s high quality of construction, and it’s exceptionally detailed documentation. I look forward to further experiments and seeing some success. Recommended, if interfacing with serial devices is in your experimentation plans.
