Beware the lack of details for unit in this website description, Just received 4-port serial to USB adapter.
As usual, Amazon waited a week to ship because it was free shipping, even though in stock.
Unit does not come with an A/C adapter, it requires 9 - 32VDC, so you have to provide DC power to
it either by buying your own adapter or finding the voltage somewhere, very inconvenient.
Instruction manual is a bad copy of an old one I guess, maybe this is old device and they dont
sell enough to warrant a real manual.
Beware, manual says unit has limited functionality on Vista, this is the reason I ordered the unit
as my old one does not support Vista. So I will try this one, but I am afraid it is same as my
old one and will not work. Will update review when I try it.
