Purpose

The LRIS Reconfiguration Manager allows Keck summit technicians to update the LRIS software so that it knows which gratings, filters, slitmasks, etc., are loaded into the instrument. This GUI replaces several old widgets and offers several useful new features:

Convenient selector buttons allow you to select from among standard gratings, filters, slitmasks, etc.
You can also, if needed, change dichroics, blue filters, and grisms
You can automatically load changes from the current day's LRIS configuration listed on the SIAS.
The GUI highlights configurations changes with a yellow background.
You can (and should) enter barcode numbers for user slitmasks, instead of typing names; the GUI automatically converts numbers to names.
When you ask it to set the configuration, the GUI will verify that the requested changes were actually made.

Usage

Normal (Automated) Usage

When the magic is working, you need to follow only two steps to reconfigure the LRIS software:

Click the blue READ SIAS CONFIG button to read today's configuration information from the Summit Instrument Activity Schedule (SIAS).
Click the green SET NEW CONFIG button to make the change.

You should receive a confirmation dialog box stating

	LRIS reconfiguration completed and confirmed!

Manual Usage

Automatic mode won't work if the DEIMOS host computer isn't fully functional, or if you have configured LRIS differently than called out on the schedule. In this case, complete the reconfiguration manually as follows:

Update the red filter list as needed by using the selector button for the appropriate position.
Update the grating list as needed by using the selector button for the appropriate position.
Update the slitmask list by doing any of the following:
- Select a longslit or other standard mask using the appropriate StdMasks selector for that position, or
- Enter the barcode number of a user mask in the appropriate entry field, or
- Enter the name of a user mask in the appropriate entry field.
If you enter a barcode number for a user mask, the software will translate the barcode number into the appropriate slitmask name when your cursor leaves the entry box, or you hit the TAB key.
Click the green SET NEW CONFIG button to make the change.

You should receive a confirmation dialog box stating

	LRIS reconfiguration completed and confirmed!
