Connect the Devices
To connect the devices:
1. Using the included USB cable, connect the DM-NUX-L2 to a host
device. The host connection powers the DM-NUX-L2.
2. Using CAT cable, connect the Link port on each device as follows:
CAUTION: Do not connect the DM-NUX-L2 or DM-NUX-R2 to a
USB-EXT extender. The USB-EXT extenders are intended for use
as point-to-point USB extenders and must not be connected to
an Ethernet LAN or any other network device via the Link port.
NOTES:
lTo comply with the European Directive (CE), Crestron
recommends using high-quality, solid core CAT5e (or better)
shielded twisted pair (STP) cable.
lThe CAT cable must have a straight-through conductor
configuration with no crossovers and must be terminated
with 8-conductor RJ-45 connectors at both ends.
lWhen used in a point-to-point over CAT cable configuration,
connect the Link port of the DM-NUX-L2 to the Link port of a
DM-NUX-R2.

Link port on the DM-NUX-R2 to the LAN port of a DigitalMedia
receiver.
DigitalMedia™ System Integration
NOTE: The DM NUX devices support high-speed (480 Mbps)
USB devices. DM8G+® Ethernet links support speeds up to
100 Mbps only. If higher bandwidth is required, ensure that
the DM NUX devices are communicating via a gigabit
Ethernet network.
3. Using USB 2.0 cables (not included), connect the USB Type-A device
ports on the DM-NUX-R2 to USB devices (USB 1.1 or 2.0 compatible).
Connect up to 30 devices using up to three USB hubs.
NOTES:
lWhen five or more DM-NUX-R2 endpoints are paired, do not
connect a web camera.
lVideo from two cameras connected to a DM-NUX-R2 may not
be viewed on different applications simultaneously.

4. Connect the DM-NUX-R2 to its included 24VDC power pack, then
connect the power pack to an AC power source.
Pair the Devices
Pairing a DM-NUX-L2 with a DM-NUX-R2 establishes a link between the
two devices. Manual pairing is required when the devices are connected
in a point-to-point over CAT cable or LAN configuration.
In a point-to-point configuration, USB switching is not performed. In a
configuration in which USB switching is to be performed, SIMPL
programming automatically pairs the extenders.
To pair a DM-NUX-L2 with a DM-NUX-R2:
1. Ensure that the units are directly connected to each other or are
connected to the same subnet on the network.
2. On the DM-NUX-L2, press and hold the Pair button for less than 10
seconds. The Link LED on the bottom panel of the extender flashes
green when the unit is in Pairing mode.
NOTE: Press and hold the Pair button a second time for less than
10 seconds to cancel Pairing mode.
3. Within 10 minutes of activating Pairing mode on the DM-NUX-L2,
press and hold the Pair button on the DM-NUX-R2 for less than 10
seconds. The Link LED on the bottom panel of the extender flashes
green when the unit is in Pairing mode.
NOTE: Press and hold the Pair button a second time for less than
10 seconds to cancel Pairing mode.
4. The Link LEDs on both units may start flashing slowly before turning
solid green. Once the Link LEDs are solid green, a valid link is
established between both units.
NOTE: If more than 10 minutes pass and the units are not yet
paired, the units switch back to the regular operation mode and
reestablish any previous links.
Unpair a Device
If pairing must be removed from a device, press and hold the Pair button
for more than 10 seconds.
Program the Devices
Program the extenders using the DMNUX Control Module in the
Crestron Studio® application or SIMPL Windows.
