Hardware Installation
This section will describe how to install your PCI board into your computer.
• Switch off the computer and disconnect from power socket.
Failure to disconnect all power cables
can result in hazardous conditions, as
there may be dangerous voltage levels
present in externally connected
cables.
• Remove the cover of the PC.

PCI 730 & PC104P-30 User Manual Eagle Technology - Data Acquisition
• Choose any open PCI slot and insert PCI board
• Insert bracket screw and ensure that the board sits firmly in the PCI socket.
• Replace the cover of the PC.
• Reconnect all power cables and switch the power on.
• The hardware installation is now completed.
Software Installation
Windows 98/2000/ME
Installing the Windows 98/2000 device driver is a very straightforward task. Because it is plug
and play Windows will auto detect the PCI board as soon as it is installed. No setup is
necessary. You simply have to supply Windows with a device driver.
Wait until Windows detects the new hardware

Select next when found.
Select next again.
When done you might have to restart your computer.
Post installation
When done with the driver installation the device manager can be open to make sure the
installation was a success.

PCI 730 & PC104P-30 User Manual Eagle Technology - Data Acquisition
• First make sure that the driver is working properly by opening the Device Manager.
• Check under the Eagle Data Acquisition list if your board is listed and working
properly. See picture below.
• Clearly you can see that the PCI device is listed and working properly.
• Further open the control panel and then the EagleDAQ folder. This dialog should list
all installed hardware. Verify your board’s properties on this dialog. See picture below

Now the first part of your installation has been completed and ready to install the EDR
Enhanced Software Development Kit.
• Run edreapi.exe found on the Eagle CD-Rom and follow the on screen instructions
Windows NT
Windows NT does not require any special setup procedure. The Windows NT driver does not
support plug and play. If Windows 2000 detects a new device simply install a default driver, or
so called placeholder. This will disable the device in the plug and play manager.
To install the Windows NT drivers simply run edrewinnt.exe on the Eagle CD-Rom. This will
automatically install the device drivers. Restart your computer when done. Open the
EagleDAQ folder in the control panel to check if your installation was successful.
Accessories
The PCI730 has got a wide variety of accessories that it can be connected too. See the Eagle
Technology catalog for more information.

3.Interconnections
The PCI730 has two connectors, an internal IDC40 connector for digital I/O and counter
timers. And an external connection situated on the card’s bracket for the analog-in and
analog-out channels.
A wide variety of genuine accessories available from Eagle Technology also make interfacing
to the PCI730 very easy. Accessories are available in the form of cables, screw terminals and
application modules.
External Connectors
PCI730
The PCI730 has an IDC40 and a DB25 male connector. A conversion cable is included that
changes the IDC40 to a DB37 male connection that can be mounted on your PC case like a
PCI card. Application modules include the PC43A3 and PC52A2.
