14 PI-MTE System Manual Version 4.C
POWER Switch and Indicator: The power
switch location and characteristics depend on the
version of ST-133 Controller that was shipped
with your system. In some versions, the power
switch, located on the front panel as shown in
Figure 2, 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. The connectors and functions located on the rear panel are further
are described on the following page. Removing and inserting boards is described in
Chapter 7, page 74.
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 must always be located in the left-most slot,
provides the following functions.
Pixel A/D conversion
Timing and synchronization of readouts
CCD scan control
Temperature control
Exposure control
Video output control
The Interface Control Module, which must always be located in the center slot,
provides the following functions.
TTL In/Out Programmable Interface
Communications Control (TAXI or USB 2.0 protocol)
Always turn the power off at the Controller before connecting or disconnecting any cable
that interconnects the camera and controller or serious damage to the CCD may result.
This damage is NOT covered by the manufacturer’s warranty.
