Moxa CP-118U - 8-port RS-232/422/485 Universal PCI serial board
This spent its life inside a computer in a class 1 cleanroom for silicon wafer production, as such it is in fantastic like-new condition. I have not tested it as i don't have the suitable cables, but i would expect its fully working. Return for replacement if not happy and I still have them in stock!

See the photos for an example of one of the cards in stock
Any other questions let me know.
