Configuring the MLC via the USB Port
The mini-Type B USB port can be used to configure the MLC via the configuration
software and to update the firmware. This USB port also functions as a power source for
the MLC during configuration.
NOTE: Do not use this port as the permanent power source for the MLC. It should be
used for power only during button and port configuration.
1. If the MLC has already been installed, access the USB port as follows:
•
MLC D models
— Remove the wallplate from the unit to access the USB port,
which is located on the front panel behind the wallplate (see
Accessing the
Covered MLC D Front Panel Features
on page 41).
•
MLC 62 RS EU and MK — Remove the MLC from the installation surface to
access the USB port, which is located on the left side panel (see Accessing
MLC 62 RS EU and MK Side and Rear Panel Features on page 42).
2. Connect a USB A to mini B cable between the USB configuration port and the USB
port on your computer.
