IR and RS-232 Device Control
The IPCP must be configured in one of the following ways before it will send commands to a
projector, display, or other device:
•
•
•
See the Global Configurator Help File or the IR Learner Help File (which come with the
software) for details on setting up the IPCP and for downloading, programming, or learning
device control commands.

Signal Flow and Generic Connection Types
An IR or an RS-232 driver file can be downloaded from the Extron website
(www.extron.com/download/index.aspx), or downloaded from the extensive Extron
driver library using the driver subscription feature within Global Configurator. The
driver is saved to a folder and commands from the driver are incorporated into the GC
configuration file for the control processor and any touchpanels that will work with it.
The configuration file is built and uploaded to the IPCP via Global Configurator.
If a driver is not already available, RS-232 or Ethernet command strings can be
entered directly from a host computer using Global Configurator. These can then be
incorporated into controls within the GC project.
IR commands can be entered directly from an IR remote control through IR learning
via IR Learner software to create a driver that the unit can use. IR learning is seldom
needed, but it is convenient for adding new or updated commands in the field in the
rare cases when a driver is not already available from Extron.
