Review on 🔌 StarTech.com Wall Mount USB to Serial RS232 Adapter - 4 Port Hub - COM Port Retention - FTDI USB to DB9 RS232 - Din Rail Compatible (ICUSB2324I), Black by Chris Meckler

This is the best! What a great device. I've struggled with different adapters for years and they always cause problems, especially when you add a new device. This box works great and replaces all those pesky adapters. I have a weather station, 2 ham radios and a communication device, they are all connected and can all be used at the same time. No problem with port numbers or anything like that. Also, eliminating the serial/USB adapters freed up the USB ports on my PC that used them. Also, all serial cables go into this box, which can be tucked away, reducing cable clutter on my PC. This is an amazing hub adapter and I would highly recommend it to anyone using more than one serial/USB adapter.
