To Install the PCI Card Driver
The following information assumes that you have already installed the WinView/32 or
WinSpec/32 software.
1. After you have secured the PCI card in the computer and replaced the cover, turn
the computer on.
2. At bootup, Windows will try to install the new hardware. If it cannot locate the
driver, you will be prompted to enter the directory path, either by keyboard entry
or by using the browse function.
If you selected AUTO PCI during the application software installation, WinView/32
or WinSpec/32 automatically put the required INF file into the Windows\Inf
directory and the PCI card driver file is copied into the Windows\System32\
Drivers directory. Refer to Table 1 for the appropriate file names and locations.

Your system has been configured to use the USB communication protocol if the
Interface Control Module installed in the ST-133 has a USB 2.0 connector as
shown in the figure at right). The advantages to the USB 2.0 interface are that it
uses a much higher data transfer rate than many common serial data formats (such
as the TAXI protocol) and it simplifies the connection to external devices. USB
supports "plug and play" -- you do not need to be heavily involved in the setup
process.
USB 2.0 Limitations
Maximum cable length is 5 meters (16.4 feet)
1 MHz is currently the upper digitization rate limit for the ST-133
Controller. Large data sets and/or long acquisition times may be subject
to data overrun because of host computer interrupts during data acquisition.
USB 2.0 is not supported by the Princeton Instruments PC Interface Library (Easy
DLLS).
Some WinView and WinSpec 2.5.X features are not fully supported with
USB 2.0. Refer to Appendix D, page 101, for more information.
Note: If you are installing the USB 2.0 interface on a laptop, you will need to perform all
of the operations described in this section. In addition, if you are using the recommended
USB Interface Card (SIIG, Inc. USB 2.0 PC Card, Model US2246), you must replace the
OrangeUSB USB 2.0 Host Controller driver installed for that card with the appropriate
