MLC 104 IP Plus Series • Introduction 4
How the MLC 104 IP Plus Series Controllers Work:
Components and Interactions
Unlike the Extron MediaLink Controller (MLC 206 Series), the MLC 104 IP Plus Series
requires and uses event files to perform all functions except basic input switching and
volume control. The event files define, monitor, and govern how a MLC 104 IP Plus Series
controller works. The following diagram is an example of how the MLC interacts with
accessories, event scripts, drivers, ports, input devices, and output devices.

Figure 2. How the MLC Works
The MLC can be configured completely via Global Configurator software. Once you have
set up how you want it to work (assigned drivers to ports, configured buttons and digital I/O
ports, and set up IP addresses and functions), that information is saved to a project file that
is uploaded into the MLC.
The configuration information is used to create the “main event” (0.evt) script file that defines
the operation of the MLC. The main event file also controls and monitors ports and optional
control accessories, and also changes made at the front panel (known as FPC, front panel
control).
Each button on the MLC and on any connected SCPs or control modules (IRCMs, CMs)
has two switch numbers assigned to it: one for the button press, one for release. Scripts are
compiled to generate the main event file to monitor events and to generate actions (such as
issuing commands and switching inputs) associated with the buttons.
