attached to MTX
USB port, but MTX
device LED is off. A USB device must have the
appropriate driver installed
on the computer operating
system. 1. Install the required USB device driver on
the computer operating system prior to
attaching the USB device to the MTX unit.
Please see your USB device
manufacturer s website for details.
2. Consult your USB device documentation,
and power your USB device with the
additional USB device manufacturer
supplied power supply (if available).
Device LED is
orange and units
are no longer
functioning. Overcurrent condition has
occurred because USB
device draws more power
than can be supplied per
USB specification (500mA). 1. Power cycle MTX.

LEDs on
MRX/RRX/MTX
units blink
intermittently. Firmware mismatch between
