ACCES PCI-DIO-120

Windows device driver information for ACCES PCI-DIO-120

The ACCES PCI-DIO-120 is a type of PCI bus hosted input and output add-on card which populated with 120 bits. The deployment of this hardware component is normally seen in an industrial setting where Programmable Peripheral Interface chip is required. The device driver for this hardware component is responsible for the support of three configurable groups consisting of eight bits each. These groups can serve as either inputs or latched outputs. The line buffers are configured automatically by the hardware logic if they should be used either for input or output purposes. Aside from the device driver of the hardware component, assigning of outputs can be done directly from the jumper selection on the card itself. Using the program controls the device driver allows for the input and output buffers to be tristated. They may also be used to interface the user inputs to the host computer system.

Each port of the hardware is assigned a specific interrupt while the system is responsible for assigning the interrupt levels. The 50-pin header which is responsible for the input and output wiring connections on the board are partially controlled by the device driver. In most devices noise or crosstalk among signals causes majority of the problems. To avoid this particular situation the flat cables are grounded. Installation of the ACCES PCI-DIO-120 requires it to occupy 32 registers of the PCI address space. The underlying operating system platform is responsible for assigning the base address as well as the Interrupt Request number used during runtime. The role of the device driver is to make sure that the operating system correctly determines the type of card installed in order to provide the necessary system requisites for operation. The base address can only be viewed. It is highly recommended you run a free registry scan for and ACCES PCI-DIO-120 errors before installing any driver updates.
