3. Installation
3.1 Overview
The Relay/Digital I/O Card PCI is a fully compliant PCI plug-and-play adapter. All
card resources (I/O address, IRQ selection) are auto-assigned by either your
system BIOS or your plug-and-play operating system.
3.2 Software Installation
3.2.1 W INDOWS U SERS
Choose Install Software at the beginning of the CD and select the Digital I/O
software drivers and install SeaI/O.
3.2.2 L INUX U SERS
Refer to the installation instructions at the beginning of the CD for details on
installing the digital I/O cards in Linux®.
3.3 System Installation
The Relay/Digital I/O Card PCI can be installed in any of the PCI expansion slots.
1. Turn off the PC’s power. Disconnect the power cord.
2. Remove the PC’s case cover.
3. Locate an available PC slot and remove the blank metal slot cover.
4. Remove the clamping portion of the bracket from the card.
5. Gently insert the Card into the slot. Make sure that the Card is seated
properly.
6. Feed the two 50-pin ribbon cables through the cutout bracket and connect
them to the card.
7. Replace the bracket retaining screw.
8. Install the clamping portion of the bracket.
9. Replace the computer cover.

RELAY/DIGITAL I/O CARD PCI—48 INPUTS OR OUTPUTS
4. Technical Description
The Relay/Digital I/O Card PCI provides 48 channels of digital I/O configurable
as inputs or outputs. Use the channels for PC-based control and automation
including sensors, switches, satellite antenna control systems, video and audio
studio automation, security control systems, and other industrial automation
systems.
4.1 Pull-Ups
Nine or ten pin bussed resistor packs are installed to provide pull-ups to input
ports. These are installed on all ports. The pull-up resistor packs are rated 10 K
ohms.
Bussed Corresponding Bussed Corresponding
Resistor Port Resistor Port
RP4 Port A1 RP1 Port A2
RP5 Port B1 RP2 Port B2
RP6 Port C1 RP3 Port C2
4.2 Software
The Relay/Digital I/O Card PCI comes with the SeaI/O suite of Windows®98, Me,
2000, and Windows NT®drivers. SeaI/O provides a consistent and straightforward
applications program interface (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.
4.3 Linux Users
The Relay/Digital I/O Card PCI ships with software for Linux, including a kernal-
mode driver, API, and the SeaIOTst diagnostic tool. The kernal-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 the 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).

RELAY/DIGITAL I/O CARD PCI—48 INPUTS OR OUTPUTS
Appendix A. Troubleshooting
A.1 Tips
Following these simple steps can eliminate most common problems.
1. Install software first. After installing the software, add the hardware. This
places the required installation files in the correct locations.
2. Identify all I/O cards currently installed in your system. This includes your
on-board serial ports, controller cards, sound cards, etc. The I/O addresses
used by these cards, as well as the IRQ (if any) should be identified.
3. Make sure that there is no conflict with currently installed cards. No two cards
can occupy the same I/O address and may not be allowed to share IRQs.
4. Make sure the Systems card is securely installed in a motherboard slot.
A.2 Calling Black Box
If you determine that your Relay/Digital I/O Card PCI—48 Inputs or Outputs is
malfunctioning, do not attempt to alter or repair the unit. It contains no user-
serviceable parts. Contact Black Box at 724-746-5500.
Before you do, make a record of the history of the problem. We will be able to
provide more efficient and accurate assistance if you have a complete description,
including:
• the nature and duration of the problem.
• when the problem occurs.
• the components involved in the problem.
• any particular application that, when used, appears to create the problem or
make it worse.
