Vacuum Compatible Flexible Tubing: The stainless-steel vacuum-compatible
¼″-OD, 36″-long flexible tubing (2825-0449) interconnects between the camera
water tubings and the vacuum feed through a 2 ¾″ ConFlat flange.
Vacuum Compatible Camera Flanges: The 2 ¾″ ConFlat flange with two
pipes (¼″ OD) and VCR fittings (2825-0562) (or with Swagelok fittings
(2825-0447) for earlier systems) and the 4 ½″ ConFlat flange with 25-pin D-sub
connector (2825-0448) are included with the system.
Interface Card
PCI Card: The Princeton Instruments (RSPI) high speed PCI card is required when
the system interface uses the TAXI protocol rather than USB 2.0. The PCI card plugs-
into the host computer's motherboard and provides the serial communication interface
between the host computer and the ST-133. Through WinView/32, the card can be
used in either High Speed PCI or PCI (Timer) mode. High Speed PCI allows data
transfer to be interrupt-driven and can give higher performance in some situations. PCI
(Timer) allows data transfer to be controlled by a polling timer.
USB 2.0 Card: This interface card is required when the system interface uses the
USB 2.0 protocol rather the TAXI protocol and the computer does not have native
USB 2.0 support. The USB 2.0 card plugs-into the host computer's motherboard and
provides the communication interface between the host computer and the ST-133.
The USB 2.0 PCI card (70USB90011) by Orange Micro is recommended for desktop
computers; the SIIG, Inc. USB 2.0 PC Card, Model US2246 is recommended for
laptop computers. Refer to www.orangemicro.com or www.siig.com, respectively,
for more information.
Vacuum Port Adapter
The Vacuum Port Adapter (2518-0943) with O-ring screws into the vacuum port on
the side of the PI-MTE. This allows you to connect the camera (with visible nose) to
a vacuum pump and pump it down to at least 1 mTorr before using the camera in a
non-vacuum environment.
