General:
The
Acton
Model 300-749 is a Remote Scan Controller for the
Acton 300i and 500i monochromator/spectrographs. Functions include
GOTO for rapidly moving the monochromator to a specific center wavelength,
scanning of wavelengths, indexing of gratings, selecting the installed grating turret
and setting the slit widths for monochromators with motorized slits. The controller
consists of an HP-48G graphics calculator with RS-232 interface and
Princeton
Instruments generated scan control software. The controller is programmed
with all the instrument functions described above displayed as convenient
menu items, with simple keystrokes enabling any of the scan functions
to be performed.
Connection and Initialization:
The scan control software for the 300-749 is installed at the factory
and the
300-749 is ready for use as it is shipped. A copy of the software is provided on disk
and may be reloaded into the HP-48G using a PC and the cables provided if it is
ever necessary to do so. This procedure is described in the last section of this
manual.
The controller is connected the monochromator using the cable provided through
the standard RS-232 port on the monochromator rear panel. The controller may be
used with any
Acton 300i or 500i monochromator; the controller is not
assigned to a specific unit. Power should be switched on the
Acton
monochromator first. After the monochromator has initialized, the 300-749
controller should be turned on.
Battery Power Management:
If the controller is not used for several minutes, the LCD screen will turn off to
save battery power. If this happens, press the on button in the lower left corner of
the keyboard to return to the menu you were using.
