"Ordering process was easy and product arrived faster than I had expected. Thanks."


We no longer carry this product. However the new Sewell Octal USB to Serial Adapter (SW-29347), does the same thing. It features the same internals (FTDI chipset), updated design and improved functionality . Best of all you get all these things at a lower price!

Don't forget to pick up a few serial cables!
