NOTE: Check the polarity of the power supply before connecting it to the MLC.
ATTENTION:
• Always use a power supply provided by or specified by Extron. Use of an
unauthorized power supply voids all regulatory compliance certification and may
cause damage to the supply and the MLC.
• The power supply must be located within the same vicinity as the Extron AV
processing equipment in an ordinary location, Pollution Degree 2, secured to the
equipment rack within the dedicated closet, podium, or desk.
• The installation must always be in accordance with the applicable provisions of
National Electrical Code ANSI/NFPA 70, article 75 and the Canadian Electrical
Code part 1, section 16. The power supply must not be permanently fixed to
building structure or similar structure.
Configuring the MLC 52 Using IR
The MLC 52 can be programmed via IR by the following methods:
• IR data transfer from an MLC 52 that has been configured
• IR learning from your projector remote control
Configuring Using IR Data Transfer (IR Beaming)
You can configure your MLC 52 by transferring button configuration data to it from
another configured MLC 52 via the two IR LEDs on the back panels of the MLCs. With
this method, you replicate (clone) the other MLC configuration on your own unit without
the use of software or cables.
The following transfers are allowed:
• From an RS model to another RS model
• From an IR model to another IR model
• From an IR model to an RS model
