MLC 104 Plus Series • Introduction
PRELIMINARY
E-mail notification — The MLC 104 IP Plus can be set up to send an e-mail when
the projector has been disconnected or the projector’s lamp has been used for
a designated number of hours.
Controlling other devices
The MLC 104 Plus Series offers two methods of projector or display control:
RS-232 or infrared (IR). The MLC can learn IR signals from remote controls to
communicate with sources such as VCRs and DVD players. Users can create their
own device drivers (IR or RS-232) or go to the Extron Web site (www.extron.com) to
obtain device drivers.

Projector Control
The MLC can control a projector or other display device by using IR or RS-232
control. The MLC must be configured for projector control in one of the following
ways before it will send commands to the projector:
• AnIRoranRS-232driverlecanbeinstalledfromadisk,downloadedfromthe
Extron Web site (www.extron.com), or downloaded from Extron using the driver
subscription feature within Global Configurator. The driver is saved to a folder
within C:\Program Files\Extron\Driver2, and it is uploaded to the MLC via
Global Configurator.
• RS-232commandstringscanbeentereddirectlyfromahostcomputerusing
Extron Global Configurator software.
• IRcommandscanbeentereddirectlyfromanIRremotecontrolthroughIR
learning and the Extron IR Learner software to create a driver that the MLC can
use. IR learning is convenient for installing new or updated commands into the
MLC in the field.
