1: Introduction
The PCI-AC51 and PCIe-AC51 adapter cards bring industry-standard Pamux
®
to modern computers
that use the Peripheral Component Interconnect (PCI) or PCI Express (PCIe) local bus.
•The PCI-AC51 is compatible with computers that feature a 5.0 or 3.3 volt PCI bus.
•The PCIe-AC51 is compatible with computers using the PCI Express bus.
These cards are an ideal choice for customers who must replace an older ISA bus-based PC that
currently uses an Opto 22 AC28 adapter card.
NOTE: The PCI-AC28 is not recommended for new designs. Use the PCI-AC51 or the PCIe-AC51 instead.
Using the PCI-AC51 or PCIe-AC51 adapter card, your computer can communicate with Opto 22
classic B4, B5, and B6 brain boards and with SNAP-B4 and SNAP-B6 brains.
•Each Pamux bus can access up to 32 remote brains.
•Each Pamux bus supports up to 512 points.
Free with these adapter cards is the Pamux Systems SDK, included on the CD that came with the
card and also available on our website, www.opto22.com. The Pamux Systems SDK supports up to
32 adapter cards. Two SDKs are included on the CD:
• Windows 8, Windows 7, and Vista operating systems—samples, source code, and the
driver. This SDK supports C#, VB.NET and other .NET languages. Existing applications n VB and
Visual C++ can be updated to Win 7 using this SDK.
• Microsoft Windows XP and 2000 operating systems—sample applications, utility
applications, and the driver. This SDK supports Microsoft Visual Basic (version 6) and Microsoft
Visual C++ (version 6). .
Use the DLL file for your OS, application, and language:
For this OS: Windows 8, Windows 7, and Vista Windows
95/98/ME/NT/2000/XP
For existing or
new application: Existing app New app in

2: Installing the Card
Follow the steps below to install the PCI-AC51 or PCIe-AC51 adapter card before you install the SDK
software. Use any available expansion slot on the computer.
You may add multiple adapter cards for convenience, but note that multiple cards do not increase
Pamux throughput. The number of Pamux accesses per computer is constant. Note the power
requirements listed in the Specifications table on page 33.
Choose the installation steps for your card:
Installing the PCI-AC51
IMPORTANT: Install the adapter card before you install the SDK software.
You can install the PCI-AC51 adapter card into any PCI expansion slot on your computer.
1. Turn off the computer. Remove the power cord and the computer’s cover.
The power cord must be removed, as a sudden spike may cause the computer to boot.
2. Before handling the card, discharge excess static electricity by touching the computer’s metal
chassis.
3. Install the card in the expansion slot. Verify that the card is properly seated in the motherboard
socket. Secure the card with the screw.

CAUTION: Do not scratch this card or other cards in the computer, as scratching may irreversibly
damage the card or other devices.
5. Reinstall the power cord. If you wish, leave the computer cover off temporarily to see the card’s
LEDs.
6. Turn on the computer.
Because the card is self-configuring, it has no jumpers. Configuration is automatically
performed by the BIOS when the card is installed.
If you are using Windows Vista or an earlier version of Windows and a “Found New Hardware”
message appears, simply click Cancel. The setup program will install the device driver
automatically.
If you have been using an AC28 adapter card for the ISA bus, you will need to make some changes
to your application because of the new adapter card. See Appendix C: Converting Applications to a
Newer Card for specific information.
Installing the PCIe-AC51
IMPORTANT: Install the adapter card before you install the SDK software.
On your computer, install the PCIe-AC51 into any PCIe expansion slot.
1. Turn off the computer. Remove the power cord and the computer’s cover.
The power cord must be removed, as a sudden spike may cause the computer to boot.
2. Before handling the card, discharge excess static electricity by touching the computer’s metal
chassis.
3. Starting with the connector end that allows the cable to lie flat, push the ribbon cable through
one of the slot openings in the computer.
4. Run the cable across the top of the adapter card (so it covers the card) and attach the cable to
the card, as shown.

NOTE: Version 2.0 and higher support only the PCI-AC51 or PCIe-AC51—not the AC28 and PCI-AC28
adapter cards.
Running the SDK Setup Program
The Pamux Systems SDK comes on the CD with the card. If you do not have the CD, you can order it
through Product Support, or you can download the SDK free from our website, www.opto22.com.
The SDK includes a sample application, Windows drivers, and user documentation.
NOTE: If you are using a different operating system or a non-PC hardware platform, you will need to write
your own driver. See Appendix D: PCIe/PCI-AC5 Register Set and Memory Locations and Appendix E: AC5
Hardware Description for more information.
1. Insert the CD in your CD-ROM drive to start the Pamux Systems SDK setup wizard.
2. Follow the wizard’s instructions.
3. On the Select Components screen, select your computer’s operating system.

SDK Contents
The Pamux Systems SDK includes a driver, sample applications, and tools to help you develop
applications for the PCI-AC51 or PCIe-AC51 adapter card and integrate it with your system. The SDK
saves you time and effort that would otherwise be spent learning the intricacies of the Pamux bus
structure.
The SDK supports C#, VB.NET and other .NET languages
NOTE: Version 2.0 and higher support only the PCI-AC51 or PCIe-AC51—not the AC28 and PCI-AC28
adapter cards.
Using the PamScan Utility
The PamScan utility is available on the Windows Start menu. It demonstrates turning digital points
on and off and configuring points as either input or output. In addition, analog point values can be
displayed and output values can be changed. PamScan is written in C# and all the source code is
included.
NOTE: Instructions are the same for the PCI-AC51 and the PCIe-AC51, although only the PCI-AC51 is
shown.
To use PamScan:
1. Select Start > All Programs > Opto 22 > PCI-AC51 > PamScan.exe

2. Make sure the reset level matches the reset level configured on the Pamux brain.
3. If you have more than one PCI-AC51 or PCIe-AC51card installed, click the card selector button.
NOTE: Normally you will use the default Adapter Card ID, which is 0.
4. In the dialog box that opens, select a card.
5. Optional Step—Flash LEDs: This step is optional because it requires you to open your computer and
see the LEDs on the card.
a. With your computer open so that you can see the LEDs, choose the card, and then click the
Flash LEDs button.
b. Notice the result on the card’s LEDs.
The program flashes the LEDs five times. If no flashing occurs, you may have selected the
wrong card. Select the next card in the list and click the Flash LEDs button again.
6. Click OK to close the dialog box. In PamScan, click Open Adapter Card.
This screen shows all four banks available on a 32-channel Pamux board. Each bank has eight
