10.4 LOW-LEVEL COMMANDS 
 
An intuitive command set is provided for those wishing to create their own programming. A list of 
these commands is provided in the user’s manual included with the monochromator. Commands 
are simple to use. For example, to query the wavelength, enter “WAVE?” The command to close 
the shutter is “SHUTTER C”.  A full list of commands is available in the Appendix of this user’s 
manual. 
 
10.5 MONO TERM SOFTWARE AND LABVIEW EXAMPLES 
 
For those users who are developing their own LabVIEW  based programs, an Application 
Programming Interface (API) document is included with the instrument. The Oriel MonoTERM 
utility is also provided for sending low-level commands to the monochromator. This is very 
convenient for assisting programmers in their software development efforts.  
 
The MonoTERM utility was developed in National Instruments LabVIEW. It's open source code, so 
it may be used to provide LabVIEW programming examples. 
 
The MonoTerm software is included on the memory stick provided with the instrument.
