Princeton Instruments PI-MAX2 System - Figure 91. ST-133 (Standard) Rear Panel Callouts

Chapter 14 System Component Descriptions 157
Standard PI-MAX Controller Rear Panel Features: The descriptions of the rear panel connectors are
keyed to the accompanying figure. Depending on your system, either the TAXI or the USB 2.0 Interface
Control Module will be installed in the second from the left slot (as you face the rear of the ST-133). In the
Figure 91, the TAXI module is shown in that position. The Fuse/Voltage label will be above or below the
Power Module.

1
Temperature Lock LED: Indicates that the
temperature control loop has locked and that
the temperature of the CCD array will be stable
to within  0.05C.
2
Video/Aux Output: If labeled Video,
composite video output is provided at this
connector. The amplitude is 1 V pk-pk and the
source impedance is 75 . Note that video
output is not currently supported under USB
2.0. If labeled Aux, this output is reserved for
future use.
3
External Sync Input: TTL input that has a 10
k pullup resistor. Allows data acquisition and
readout to be synchronized with external events.
Through software, positive or negative (default)
triggering can be selected.
4
Output: WinView/32 (ver. 2.4 and
higher) software selectable NOT SCAN or
SHUTTER signal. Default is SHUTTER.
5
Output: Initially HIGH. Changes state
on completion of cleaning cycles before the first
exposure.
6
Zero Adjustment: Bias potentiometers control
the offset values of the Fast (F) and Slow (S) A/D
converters. Preadjusted at factory. If
potentiometers are not present, bias may be
software-settable.
15
Timing Gen.: Gate Start/Stop and Bracket signals
are provided at this connector. This output must
be cabled to the PI-MAX Timing Gen connector.
7
Detector Connector: Transmits control
information to the camera and receives data
back from the camera via the Detector-
Controller cable.
16
Remote Shutter Connector: Unless the PI-MAX
system is powering a slit shutter for a spectrograph,
this connector can be ignored.
8
TTL In/Out: User-programmable interface
with eight input bits and eight output bits that
can be written to or polled for additional
control or functionality. Output is not currently
supported under USB 2.0. See Chapter 13.
17
Shutter Setting Selector: Sets the shutter hold
voltage. Unless the PI-MAX system is powering
a slit shutter for a spectrograph, this functionality
can be ignored.
9
AUX Output: Reserved for future use.
18
Aux. Trig. Out: AC-coupled variable delay trigger
output for synchronizing other system components
with PTG. The host software sets the Delay Time of
this output with respect to the PTG trigger time.
This output does not need to be connected to the
PI-MAX.
