Crestron DM-NUX-L2-1G User manual

The DM NUX USB over Network Wall Plates with Routing
(DM-NUX-L2-1G and DM-NUX-R2-1G) deliver reliable, high-speed USB
signal extension and routing for USB 1.0, 1.1, and 2.0 devices throughout
a home, business, or campus for distances up to 330ft (100m).
Featuring Virtual Hub capabilities, five DM-NUX-R2-1G endpoints may
simultaneously be connected to a single DM-NUX-L2-1G endpoint.
Creating this virtual hub allows numerous USB devices to control a
single host device (such as a PC).1The USB signals are transported over
the local network and managed through a Crestron control system.
The DM-NUX-L2-1G and DM-NUX-R2-1G are functionally similar. For
simplicity within this guide, the term "USB endpoint" is used except
where noted. The USB endpoints are also compatible with the USB over
Ethernet Extenders with Routing (DM-NUX-L2 and DM-NUX-R2).

DM NUX USB over Network Wall Plates with Routing

Install the USB Endpoint
The USB endpoint uses Power over Ethernet (PoE) and mounts in a
North American, unobstructed, 1-gang electrical box (not included). A
minimum mounting depth of 2in. (51mm) is required. The
DM-NUX-L2-1G also receives power from the USB host port.
The DM-NUX-L2-1G and DM-NUX-R2-1G may be used without a control
system or DigitalMedia™ system to offer point-to-point USB extension
over a LAN or a dedicated CAT5e (or higher) cable.
NOTE: A ferrite bead is provided to reduce or prevent EMI
(electromagnetic interference). When using a power source other
than PoE, Crestron recommends installing this ferrite bead on the
power supply cable close to the device.
Connect the USB Endpoints
Connect the DM-NUX-L2-1G and DM-NUX-R2-1G.
NOTE: Signal routing is not supported when the DM-NUX-L2-1G and
DM-NUX-R2-1G are used to provide point-to-point USB extension or
when PoE is not being used. In addition, a separate 24V 0.75A power
supply is needed.
1. Feed the CAT5e (or better) shielded twisted-pair (STP) cable through
the opening on the top of the electrical box.
NOTES:
lTo comply with the European Directive (CE), Crestron
recommends using high-quality, solid core CAT5e (or better)
shielded twisted pair (STP) cable.
lThe CAT5e (or better) cable must have a straight-through
conductor configuration with no crossovers and must be
terminated with 8-conductor RJ45 connectors at both ends.
2. Using CAT5e (or better) cable, connect the LINK port on each
endpoint to an Ethernet network, the LAN port of a DigitalMedia
transmitter or receiver, or to the LINK port of another DM NUX
endpoint. The maximum cable distance is 330ft (100m).
CAUTION: Do not connect the DM-NUX-L2-1G or DM-NUX-R2-1G
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.
3. Using a USB 2.0A to B cable (not included), connect the USB B end
to the DM-NUX-L2-1G host port ( ), and connect the USB A end
to a USB Type A port on the host device (USB 1.1 or 2.0 compatible).

extender or when the DM-NUX-L2-1G is connected to the Host device.
NOTE: The CONFIG jack on the USB endpoint is reserved for factory
use only.
Mount the USB Endpoint
1. Place the USB endpoint into the electrical box.
2. Use two included 6-32 x 1/4in. pan-head mounting screws to attach
the USB endpoint to the electrical box.
3. Attach a faceplate (not included) to the USB endpoint.

Connect the USB Devices
1. Install any software on the host computer that is required to operate
the USB device(s). Refer to the USB device documentation for
installation instructions.
2. Using USB 2.0 cables (not supplied), connect the USB devices (USB
1.1 or 2.0 compatible) to the DM-NUX-R2-1G. Up to four USB devices
may be connected.
3. Confirm that each USB device is properly installed on the host
computer and that it is detected by the operating system.
NOTES:
lThe USB endpoint is engineered to deliver maximum
compatibility with the widest possible range of devices. Crestron
does not guarantee that all USB devices or hosts are compatible
with the USB endpoint.
lA web camera may not be used when five or more
DM-NUX-R2-1G endpoints are paired.
lVideo from two cameras connected to a DM-NUX-R2-1G may not
be viewed on different applications simultaneously.
lThe USB endpoint supports high-speed (480Mbps) USB devices;
however, DM 8G+® Ethernet links support speeds up to 100Mbps
only. If higher bandwidth is required, ensure that the USB
endpoint is communicating via a gigabit Ethernet network.
Check the Installation
Check that the ACT, HOST, LINK, and PWR LEDs light on both the
DM-NUX-L2-1G and the DM-NUX-R2-1G. If the HOST or LINK LEDs do
not light, then the cabling between the USB endpoints and the network
may be installed incorrectly or may be defective.
The following table describes the behavior of the LEDs on the front
panel of the USBendpoint.
LED Color Description
ACT Flashing
amber
Data transmission is occurring between the
DM-NUX-L2-1G and the DM-NUX-R2-1G.
HOST Solid green The host device is recognizing the USB
endpoint.
LINK Solid green A valid link is established between the USB
endpoint.
Fast-flashing
green
The USB endpoint is in Pairing mode.
Slow-flashing

If the USB endpoint system does not detect correctly or fails to detect,
refer to Troubleshoot the USB Endpoint.
Program the USB Endpoint
Program the USB endpoint using the DM-NUX Module in the Crestron
Studio® application or SIMPL Windows.
Pair the USB Endpoint (Optional)
Pairing the USB endpoint establishes a link between the DM-NUX-L2-1G
and DM-NUX-R2-1G. Manual pairing may be performed when a
DM-NUX-L2-1G and DM-NUX-R2-1G are directly connected to each
other in a point-to-point configuration or connected over the Network
for multipoint connections. 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.
Pair a DM-NUX-L2-1G to a DM-NUX-R2-1G.
1. Ensure that the DM-NUX-L2-1G is directly connected to the
DM-NUX-R2-1G.
2. On the DM-NUX-L2-1G, press and hold the PAIR button for less than
10 seconds. The LINK LED on the front panel of the endpoint starts
flashing green fast, indicating that the endpoint 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-L2-1G,
press and hold the PAIR button on the DM-NUX-R2-1G for less than
10 seconds. The LINK LED on the endpoint starts flashing green,
indicating that 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. Observe that the LINK LEDs on both endpoints may start flashing
slowly before turning solid green. Once the LINK LEDs are solid green,
a valid link is established between both endpoints.
NOTE: If more than 10 minutes pass and the endpoints are not
yet paired, the endpoints switch back to the regular mode of
operation and reestablish the previous links they had (if any).
Unpair a USB Endpoint
If pairing must be removed from an endpoint, press and hold the PAIR
button for more than 10 seconds.
