8.3.1.2 - Communications
The radio buttons in the Communications section of the Spectrograph Setup Dialog box can be used to
establish an interface between your computer and the spectrograph.
If you are using an Andor Shamrock, you can also choose between USB or I
2
C control links. Select Shamrock
Control from the Hardware drop-down menu and the Shamrock Control dialog box appears e.g.:
Select USB for USB control or for I
2
C select CCD, then click OK.
NOTE: When a Shamrock is connected, the Shamrock icon
appears in the menu bar of the main
window.
In the event of an error in communications occurring, you will be prompted by a message, e.g.:
8.3.1.3 - Other Spectographs
If for example you have selected the Oriel MS257 spectrograph, you can now Load Factory File. This file
supplies the system with important configuration details of your particular spectrograph. It must be loaded for
the system to control the spectrograph correctly. The Factory File will have been supplied on diskette with your
MS257 spectrograph. Performing Load Factory File lets you save the file contents to the .ini file included with
Andor’s software. The Factory File need not be loaded again.
When you click the Load Factory File button you will see a typical Windows ‘Open File’ dialog box. Select the
directory and the filename of the file you wish to load, and click OK. The Factory File is now loaded.
8.3.1.4 - Reverse Spectrum
Some spectrographs produce somewhat ‘atypical’ spectra, where longer wavelengths (red) are to the left (as
viewed from the detector), and shorter wavelengths (blue) are to the right. If for example the MS127 or FICS
spectrographs are selected from the drop-down list, a tick will appear in the Reverse Spectrum check box.
Because both these spectrographs are of this type, the Reverse Spectrum check box is ticked by default when
these spectrographs are selected. The system then uses software to ‘reverse’ the output of the detector when it
generates a data window, presenting the display in the more usual orientation.
You may, if you wish, disable the Reverse Spectrum function by clicking the check box.
