Applications Serial Attached Devices Serial Networking/Monitoring Equipment Data Acquisition System POS Terminal & Industrial PC Parallel/printer port based applications Add-On I/O cards - serial/Parallel/USB Embedded systems - for I/O expansion Installing the PCI Express I/O card to your computer: 1.Tum off your computer and all devices connected to it. 2.Remove the Computer's cover, Refer to your computer user's manual for more details. 3.Find an unused PCl Express slot and remove the metal bracket. Save the bracket screw for lateruse. 4.Align the card horizontally with respect to the PCI slot and insert it into the slot. Once you haveproperly positioned the PCI Express VO card into the slot secure the PCI Express I/O card withthe bracket screw you have saved. 5.Replace the computer's cover.
