File Types: a Key to Extron-specific File Names
You must have a basic understanding of the types of files used by this MLC
controller in order to decide what (if anything) to do with them.
___.cdc — These are compressed device configuration files created and used by
Global Configurator.
C ___.cdc files should NOT be deleted.
___.eir — These are driver files containing infrared commands. There is a separate
___.eir file for each device the MLC controls via infrared communication.
This is the type of file created during IR learning. Via Global Configurator,
these files can be imported and associated with one of the controller’s IR/
Serial ports.
___.eml — E-mail template files have the .eml extension. These files are used to
generate e-mail messages such as those regarding projector disconnection
and excessive projector lamp hours. The first line of the file is the subject.
The rest of the file contains the body of the e-mail. For the MLC 104 IP Plus,
these files are numerically named (1 through 64). For example, 1.eml, 2.eml,
3.eml ,... 64.eml.
___.evt — These are event files, the most important files for the functioning of the
MLC. Almost everything the MLC does is coordinated by the scripts in the
main event file, 0.evt. The other event files perform device driver functions.
When the Windows-based configuration program creates event files, it names
(numbers) the files according to port associations. For example, the main
event file, 0.evt, contains instructions for the MLC’s internal operations, while
2.evt is related to the Display port.
C Event files should NOT be deleted. They are necessary for the MLC’s
operation. Never delete the main event file ( 0.evt).
________.gc2 or ________.gcz — These are configuration files that are used by
Global Configurator only, not by the MLC. They contain configuration
settings that must be processed by Global Configurator to create device
configuration and event files for the MLC.
________.s19 — This is an Extron-supplied firmware update file. When the
firmware is replaced, the MLC is also automatically reset to factory default
settings. This file is not displayed on the File Manager page. See appendix B
for details on firmware updates. Firmware can’t be updated by loading an
___.s19 file through the file manager.
