use. IR learning is convenient for installing new or updated commands into the
IPL 250 in the field.
Refer to the Global Configurator help file or the IR Learner help file (which
comes with the software) for details on setting up the IPL and for downloading,
programming, or learning device control commands.
How the IPL 250 Works: Components and Interactions
The IPL 250 requires and uses event files to perform functions. The event files
define, monitor, and govern how an IPL 250 works. The following diagrams are
examples of how the IPL interacts with accessories, event scripts, drivers, ports, and
input and output devices.

The IPL can be configured completely via Global Configurator software. Once you
have set up how you want it to work (assigned drivers to ports, configured relays
and contact closure input, and set up IP addresses and functions), that information
is saved to a project file that is uploaded into the IPL.
The configuration information is used to create the “main event” (0.evt) script file
that defines the IPL’s operation. The main event file also controls and monitors
ports and optional control accessories. Scripts are compiled to generate the main
event file to monitor events and to generate actions (such as issuing commands and
triggering relays).
