Technical Description

• The PIO-32.PCI provides 32 channels of digital I/O configurable as inputs or outputs, which can be utilized for PC based control and automation of equipment. Uses include sensors, switches, satellite antenna control systems, video and audio studio automation, security control systems, and other industrial automation systems.
• 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. This gives the user the ability to customize the combination of inputs and outputs as needed.
• For development purposes, the card’s DB37 connector can be interfaced directly to Sealevel’s terminal block kit, Part# KT-101. The KT-101 kit, consisting of a 6 ft. M/F cable and positive tension screw terminal block provides a simple means to connect field wiring the PIO-32.PCI.

Features

• 32 Channels of Digital I/O configurable as inputs or outputs
• Implemented as 4 ports of 8 channels each of I/O providing flexible operation
• Terminal Block and cable kit available to simplify field wiring requirements
• Supports all PCI interrupts

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. Popular development environments are supported for application development. SeaI/O includes sample applications and a utility for configuring the driver parameters under Windows, further simplifying installation.

Linux Users
The SeaI/O for Linux, includes a kernel-mode driver, API, and the SeaIOTst diagnostic tool. The kernel-mode driver is provided as a module, so future driver upgrades may be performed with minimal (usually zero) downtime. The Linux API is identical to its Windows counterpart, facilitating quick and easy ports of existing SeaI/O-aware applications to the Linux operating system. All source code for the Linux software suite is provided under the GNU Public License (GPL v2.0), to assist in “roll-your-own”-type applications.

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. Complete documentation of the API can be found in its accompanying help file.

Presetting an Output Port
Each port has an output register associated with it. This register may be written and retains its value whether the port is configured as an input or an output. To preset the value of an output port the program should write to the port when it is configured as an input then configure it as an output. Inputs cannot be written to with relative addressing, absolute addressing must be used. Refer to Relative and Absolute Addressing below.

Interrupts
Interrupt sampling can be set up in the API. Port A bit zero is the interrupt source(pin 20). Refer to the API section in the SeaI/O help file for more detailed information.

Port Configuration
Each eight-bit port can be configured as inputs or outputs. The API provides a set adapter state call to access the control words. For this device, one control word is used.

Control Word 0 = input 1 = output

• Port A – Bit 0
• Port B – Bit 1
• Port C – Bit 2
• Port D – Bit 3

The control panel also allows you to configure the device. Your program can override the control panel configuration when executed, but the control panel configuration will be the default on power up. The default settings are based on the settings in the control panel application when last changed and saved after re-booting.

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.
• Relative addressing mode, on the other hand, refers to input and output ports in a logical fashion. With a Port argument of 0 and an API function meant to output data, the first (0th) output port on the device will be utilized. Likewise, with a Port argument of 0 and an API function designed to input data, the first (0th) input port of the device will be utilized.
• In all addressing modes, port numbers are zero-indexed; that is, the first port is port #0, the second port is #1, the third #2, and so on.
• Given Port A and Port D are inputs and Port B, Port C are outputs, the Tables below show Absolute address, and the relative address. The absolute address will be the same for any configuration, while the relative address will depend on the particular configuration.

Absolute and Relative Addressing

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. If an input is driven high (2V to 5.25 V) it will read as a logical one (1), if driven low (0V to 0.8V) it will read as a logical zero (0).

• Reading the Outputs
  The value that is currently being used to drive the outputs will be returned.

• Presetting an Output Port
  Each port has an output register associated with it. This register may be written and retains its value whether the port is configured as an input or an output. To preset the value of an output port the program should write to the port when it is configured as an input then configure it as an output.

• Writing the Outputs
  The outputs are active high. Writing a one (1) corresponds to 5V while writing a zero (0) corresponds to 0V, at the output.

• Port Configuration
  Each port can be configured as an input or an output by writing to its direction control bit, refer to the table below.

• Interrupts
  Interrupts can be set up as shown on the following page. Port A1 bit zero is the interrupt source (pin 20).

Register Description (for direct hardware control)

Address| Mode| D7| D6| D5| D4| D3| D2| D1| D0
---|---|---|---|---|---|---|---|---|---
Base+0| R/W| PAD7| PAD6| PAD5| PAD4| PAD3| PAD2| PAD1| PAD0
Base+1| R/W| PBD7| PBD6| PBD5| PBD4| PBD3| PBD2| PBD1| PBD0

Base+6| R Only| {0}| {0}| {0}| {0}| {0}| {0}| {0}| {0}
Base+7| R Only| {0}| {0}| {0}| {0}| {0}| {0}| {0}| {0}

NOTE All ports are set to input after reset or power up.
Interrupt source is Base+0 bit D0. When selecting the Interrupt Mode, always disable interrupts prior to changing or setting states. This will help prevent inadvertent or un-expected interrupts from occurring. When using the high and low level interrupts, a change in state of the input must occur before the interrupt can be cleared. The device providing the input to Base +0, bit D0 must do this.
