Aux. Trig. Out: Ac coupled variable delay trigger output for synchronizing
other system components with PTG. The host software sets the Delay
Time of the auxiliary trigger output with respect to the PTG trigger time.
This output does not need to be connected to PI-MAX.
Time of the auxiliary trigger output with respect to the PTG trigger time.
This output does not need to be connected to PI-MAX.
Trig. Indicator: LED trigger indicator. 100 ms flash is produced each time the
PTG triggers. With repetition rates faster than 10 Hz, indicator glows
continuously.

Power Input Module: This module contains the line-cord socket, the Power On/Off
switch and two fuses. The power and fuse requirements are printed on the panel above
the module. For more detailed information, see "Power Requirements" on page 13.

Software Installation
It is necessary to install the application software before the controller can be operated and
data acquired. The installation procedure will vary according to the computer type,
operating controller, and type of application software. See your software manual for
detailed software installation and software operation information.

Imaging Field of View
When used for two-dimensional imaging applications, Princeton Instruments cameras
closely imitate a standard 35 mm camera. Since the CCD is not the same size as the film
plane of a 35 mm camera, the field of view at a given distance is somewhat different. The
imaging field of view is indicated in Figure 6.
