Technical Description

The OMG-PCI -DIO32 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 OMG-PCI -DIO32’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.

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

Windows Software

The OMG-PCI-DIO32 ships with the SeaI/O suite of Windows 98/NT/ME/2000
drivers. SeaI/O 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,
including Visual C++, Visual Basic, and Delphi, are supported for application
development. SeaI/O includes a utility for configuring the driver parameters
under Windows, further simplifying installation. Sample applications are included
to facilitate rapid application development.

Linux Software

The OMG-PCI-DIO32 ships with software for Linux, including 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
Linux operating system. All source code for the Linux software suite is provided

Application Programmers Interface (API)

Most modern operating systems do not allow direct hardware access. The SeaIO
driver and API have been included 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 OMG-PCI -DIO32 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 wh ether 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. See Relative

Addressing vs. Absolute Addressing below.

Interrupts:

Interrupt sampling can be set up in the API. Port A bit zero is the interrupt
source(pin 47) . 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

Note: The control panel also allows you to configure the device. Your program
can over ride 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.

OMG-PCI-DIO32 Page 8

Programming

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 (0
argument of 0 and an API function designed to input data, the first (0
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, Port D are inputs and Port B, Port C are outputs, the Tables below
he 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.

Direct Hardware Control

In systems where the users program has direct access to the hardware (DOS) the
table below gives the mapping and functions that the OM G-PCI-DIO32 provide.
The address of each eight-bit port is calculated as shown in the table on the
following page, the cards 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). If an
input is not driven it will read as a one (1) due to the 10K ohm pull up resistors on
each port.

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 47) .
