Extron Electronics MLC 52 Series User Guide - Manual (Page 22)

To transmit configuration data via IR, both the transferring and the receiving MLCs must
be removed from the wall, electrical box, or furniture, and both must be powered on. The
MLC that is already configured can be powered by an external power supply, or it can
share a power supply with the unit that will be configured.
NOTE: All MLC 52 models use the same IR data transfer procedure.
1. On the MLC from which the configuration will be transferred (the donor
unit), set
all configuration switches to Off (down).
2. On the MLC that will receive the data, set switch 2 to On (up) and all the
other switches to Off (down).
3. Position the two units so that the IR Transmit and Receive LEDs of both MLCs are
facing each other, and no more than 6 inches (15 cm) apart.

Transfer
The data transfer begins when the receiving unit detects the transmitting unit. The
process takes 15 to 20 seconds to complete, though it may take longer if the
transmitting unit has multiple commands programmed on each button.
