Windows device driver information for SP Serial 550 PCI

This hardware component is an expansion card which plugs into a vacant PCI slot on the computer motherboard to provide the host computer system with additional cabling possibilities for both serial and parallel interfaces. It is known as an adapter card which is capable of delivering data transfer rates of up to 115.2 kilobits per second depending on the capability of the attached hardware component. Like most devices which are installed internally it requires the corresponding extraction of its device driver which will make it both operational and functional. When properly installed in the host computer system it will be immediately detected upon reboot and will allow the underlying operating system to detect any device attached to its interface port. These types of hardware components are normally referred to as expansion cards because they supplement the existing functionality of the host computer system.

In terms of hardware functionality the SP Serial 550 PCI is designed to minimize if not completely eliminate the occurrence of bottlenecks during data transmission. Using the manufacturer provided device driver it can also address common problems that involve Interrupt Requests in the host computer system. Basically every hardware component is assigned a corresponding address and Interrupt Request which allows the underlying operating system platform to identify the attached devices. Sometimes when massive amounts of information is processed there can be bottlenecks when accessing these IRQs. The device driver of the SP Serial 550 PCI helps to avoid these instances by allowing the expansion card to take control of the data traffic for the devices attached to its ports. By handling the input and output traffic in a single card with high speed bidirectional interfaces the computer user gains a boost in the overall performance of the host machine. For older computer systems the computer user now has the ability of connecting external devices like modems, scanners, and additional printers among others. It is highly recommended you run a free registry scan for and SP Serial 550 PCI errors before installing any driver updates.
