Setting up a USB 2.0 Interface
Administrator privileges are required under Windows
to install software and hardware.
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.

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 Microsoft driver. Instructions for making the replacement are included in
"To Update the OrangeUSB USB 2.0 Driver", below.
To Replace a TAXI Module Interface Control Module with a USB 2.0
Module: If you ordered a USB 2.0 Interface module separately and are retrofitting an
ST-133 that you already own, follow the module replacement instructions in
"Removing/Installing a Plug-In Module" starting on page 113.
To Update the OrangeUSB USB 2.0 Driver:
This procedure is highly recommended when a laptop computer will be used to
communicate with the ST-133. As stated before, we recommend the SIIG, Inc. USB 2.0
PC Card, Model US2246 if USB 2.0 is not native to the laptop's motherboard. To reduce
the instances of data overruns and serial violations, the OrangeUSB USB 2.0 Host
Controller installed for the SIIG card, should be replaced by the appropriate Microsoft
driver (Windows 2000 or Windows XP, depending on the laptop's operating system.)
Note: This procedure may also be performed for desktop computers that use the Orange
Micro 70USB90011 USB2.0 PCI.

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 (EZ-
DLLS).
Some WinX (WinView and WinSpec) 2.5.X features are not fully supported
with USB 2.0. Refer to Appendix G, page 153, for more information.
