ST-133 Controller
Electronics: The Model ST-133 is a compact, high performance CCD Camera
Controller for operation with Princeton Instruments cameras. Designed for high speed
and high performance image acquisition, the ST-133 offers data transfer at speeds up to 5
Megapixel per second, standard video output for focusing and alignment. A variety of
A/D converters are available to meet different speed and resolution requirements.
In addition to containing the power supply, the controller contains the analog and digital
electronics, scan control and exposure timing hardware, and controller I/O connectors, all
mounted on user-accessible plug-in modules. This highly modularized design gives
flexibility and allows for convenient servicing.
POWER Switch and Indicator: The power s
witch
location (see Figure 2) and characteristics depend on the
version of ST-133 Controller that was shipped with y
our
system. In some versions, the power switch is on the
front and has an integral indicator LED that lights
whenever the ST-133 is powered. In other versions, the
power switch is located on the back of the ST-133 and
does not include an indicator LED.
Rear Panel Connectors: There are three controller
board slots. Two are occupied by
the plug-in cards that
provide various controller functions. The third,

covered with a blank panel, is reserved for future development. The left-most plug-in
card is the Analog/Control module. Adjacent to it is the Interface Control module. Both
modules align with top and bottom tracks and mate with a passive back-plane via a 64-
pin DIN connector. For proper operation, the location of the modules should not be
changed. Each board is secured by two screws that also ground each module’s front
panel. Removing and inserting boards is described in Chapter 9, pages
125-126.
WARNING
To minimize the risk of equipment damage, a module should never be removed or
installed when the system is powered.
The Analog/Control Module, which should always be located in the left-most slot,
provides the following functions.
• Pixel A/D conversion • Tim
ing and synchronization of readouts
• CCD scan control • Tem
perature control
• Exposure control • Video output control
The Interface Control Module, which should alway
s be located in the center slot,
provides the following functions.
• TTL In/Out Program
mable Interface
• Com
munications Control (TAXI or USB 2.0 protocol)
