I have an Polygraph instrument that I need to connect to a Laptop. The laptop has 2 usb and I female db9(?). The instruement only has a female db9. How can I connect the 2 without buying a 179.99 docking station?
Sounds like you need a USB to Serial adapter. Here is an example. http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=166218&CatId=464 There are more expensive ones out there, so do a little homework to find out what will work with your peripheral. ~Rich
