Extron electronic MLC 52 manual Data Transfer

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).

Figure 15. Setting Up Transmitting and Receiving Units for Wireless Data 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.
