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. 
 
Operation of the 300-749 Controller: 
 
After the Acton monochromator is turned on and initialized and the 300-749 
controller is turned on, the following menu will be shown at the bottom of the 
LCD screen:  SP300   UTIL
