  • Page 9: Technical Description

    The PIO-32.PCI’s 32 channels consist of 4 ports of I/O, each port configurable as either input or output, to suit the task at hand. The status of each of the 4 ports is user selectable as input or output by simply writing a control word to the port register.

  • Page 10: Software

    Software The PIO-32.PCI Software The SeaI/O software provides the user with a consistent and straightforward API, allowing the developer to concentrate on the details of the application as opposed to low level driver development.

  • Page 12: Electrical Characteristics

    Electrical Characteristics The table below provides the electrical characteristics of each Input/Output. Each port is buffered with a 74LS245 octal bi-directional transceiver. Each input is capable of sinking up to 24 mA, while each output can source up to 15 mA. Recommended Operating Conditions Input 5.25 V...

  • Page 13: Programming

    Programming Application Programmers Interface (API) Most modern operating systems do not allow direct hardware access. The SeaIO driver and API are available to provide control over the hardware in Windows and Linux environments. The purpose of this section of the manual is to help the customer with the mapping of the API to the actual inputs for the 8001 specifically.
  • Page 14 Relative Addressing vs. Absolute Addressing The SeaIO API makes a distinction between “absolute” and “relative” addressing modes. In absolute addressing mode, the Port argument to the API function acts as a simple byte offset from the base I/O address of the device. For instance, Port #0 refers to the I/O address base + 0; Port #1 refers to the I/O address base + 1.
  • Page 15 API Bit # Relative API Bit # Absolute Address Port Bit Address (function) (function) 0 ( R/w ) 0 ( R ) A0 - Input 1 ( R/w ) 1 ( R ) A1 - Input 2 ( R/w ) 2 ( R ) A2 - Input 3 ( R/w )

  • Page 16: Direct Hardware Control

    Direct Hardware Control In systems where the user’s program has direct access to the hardware (DOS) the table below gives the mapping and functions that the 8001 provide. The address of each eight-bit port is calculated as shown in the table on the following page, the card’s base address plus an offset. Reading the Inputs The inputs are active high.
