Need to drive your I/O from a Notebook PC?  Sealevel Systems has the solution!

Today's Notebook PCs ship with 1 (or in some cases no) onboard serial ports. Sealevel USB and PCMCIA Serial I/O products bypass this limitation by providing additional serial ports for all of your mobile data acquisition, automation and control needs. Isolated USB products are also available to eliminate the effects of ground loop current and surges.
