Chapter 4 System Setup
28 Lynx II DSA User's Manual - 7096089
Because “New” is a destructive operation, selecting it will cause the program to ask for a
confirmation in one of two ways:
1. If the Definition currently being displayed has not been changed since it was last
saved (no asterisk in the Title Bar), you will be asked if you want to erase the
current Definition. Click on OK to erase it, or Cancel to return to the Input
Definition Editor.
2. If the Definition currently being displayed has been changed but not saved, you
will be given a chance to save it.
The Input Definition Report
The File | Report menu command always saves to a disk file, but if you click on Yes in
the dialog box that pops up, you can send the report to a disk file and print the report as
well. Click on No to save it to a disk file without printing the report.
The MCA Input Definition (MID) Editor
This section discusses using the MCA Input Definition (MID) Editor. The MID Editor is
optional, part of the Genie 2000 product, and not a part of the Lynx II product.
Note: This shows examples of screens and entry names that you might see, not
necessarily exact details for your configuration, which can vary.
The MID Editor is used to set parameters of your MCA as desired, and then save those
settings as a MID file. In addition to using the MID Editor to create a new input definition,
it may be used to edit an existing MID file. You may choose to use the MID Editor to
change the default settings for some of the Lynx II DSA's programmable components.
Basic Concepts
We'll review some basic concepts that are important to understand before actually getting
into the details of how you define your system's MCAs.
Multiple MCA Configurations
Since MCA definitions are saved in individual files called MID files, you can have as
many definitions as you like. For example, you might have one MCA defined as a 1K
Sodium Iodide Spectroscopy MCA in one file and another as a 2K Sodium Iodide
Spectroscopy MCA in another file.
Although MID files can reside in your PC’s disk storage, to establish communication with
a Lynx II, the device’s MCA definition(s) must be loaded into Genie’s run-time
configuration database managed by the Virtual Data Manager (VDM).
A previously-loaded configuration can be edited with the MID Editor, but must first be
unloaded from the database, edited, then re-loaded back into the database.
The MID Wizard can create and load a new MCA definition; it cannot unload a definition
once loaded into the database. The MID Editor must be used for unloading, editing, and
re-loading.
