We used this port for a few weeks, but had serious issues with the driver and ultimately replaced with a better port. The com addresses are arbitrarily assigned which makes it difficult to set up. We also randomly lost ports that would not communicate with our control software. I would recommend that you purchase a more reliable unit from another vendor.

This does exactly what it's supposed to. After installing the drivers i had 8 new com ports all working in parallel. You do have to work out which com device maps to which physical port but that's straightforward and a windows 'feature' rather than a failing of the device itself. I'm using it powered only by the USB connection and have had no issues, recommended.

I used this to successfully connect 8 RS-232 temperature controllers to a single USB port. I am reading at .5 second intervals and it works well. The weird thing is that the port mapping was not sequential to the port numbering on the box. It was a hit and miss thing. I had to start up polling on a single port and move the device connection to the different ports to find which one was active. And for some reason, it even skipped over to unused port numbers. So, I had ports 1 - 6 mapped to Com 8 - Com 13 and then 7 and 8 mapped to Com 15 and 16. Com 1 - 6 did not map to 8 and 13 in that order either. port 1 was connected to com 10 and some random order. I did order a second one for another system so it should show you that the mapping was not a primary concern and once I figured it out, it should never have to be redone. I unplugged and replugged several times and the port mapping remained in tack.

We have been using it to mass install the firmware in our circuit boards. It happened that one of our cable broke and shorted the RTS,CTS and some data outputs to GND for quite a few hours and it did not cause any damage to this RS232 adapter. This thing is bulletproof.

Used it as console ports for multiple Cisco devices. Worked exactly as I needed it to. Ended up buying three of them. Now I can remote into a Windows 2012 server and connect to 24 different Cisco Console ports.

Works great for serial/ip interfacing. Just as good as comtrol/digi so far.

Had a bit of trouble matching COM ports to physical ports. After the first device the remaining devices worked great!

Rugged design. Will work to add COM ports to a PC. I found the "COM Retention: COM Port assignments maintained across reboot" statement to be misleading. I was expecting the product to do this, but it relies on Windows to do it. And Windows was not remembering the COM Ports across reboot with current drivers that Windows 7 kept installing for the product. At one point I was up in the 20s for COM Port numbering. Support was not much help with the issue. Eventually got it resolved thru much trial and error.

Great adapter, very rugged, saves USB ports on your machine. Only oddity is that the Windows 7 64-bit driver numbers the ports a little weirdly. On my machine, the ports are COM20 through COM27. The correspondence between COM and unit labelling is: COM20 is 2, COM21 is 1, COM22 is 4, COM23 is 3, etc. I have used up to six of the eight ports and have had no reliability issues or disconnects for hours at a time. Drives 50 foot serial cables with no problems. I do use an external power supply most of the time, but don't think I really need it.
