USB 2.0 Routing
DM-NVX-36x(C) devices support the extension of USB 2.0 signals. A DM-NVX-36x(C)
device provides a USB 2.0 DEVICE port and a USB 2.0 HOST port; however, both ports
cannot be used simultaneously. The DEVICE port on one DM NVX device can be
connected to a computer or other host device. The HOST port on another DM NVX
device can be connected to a USB mouse, keyboard, or other peripheral device.
Connection to the DEVICE port is referred to as a local USB connection, and the
DM NVX device is referred to as the local extender. Connection to the HOST port is
referred to as a remote USB connection, and the DM NVX device is referred to as a
remote extender.
NOTE:
DM-NVX-36x(C) devices are engineered to deliver maximum compatibility with
the widest possible range of USB products. In addition to KVM (keyboard, video, mouse)
switch functionality, various types of USB peripheral devices are supported, including
whiteboards, touch screens, game controllers, web cameras, mobile devices, headsets,
and flash drives. Crestron does not guarantee that all USB products are compatible with
DM NVX devices.
For USB 2.0 Layer 2 transport, one local (DEVICE port) connection supports up to seven
remote (HOST port) connections simultaneously. When multiple remote connections
are required, a hub must be used to connect to the HOST port of each DM NVX
remote extender.
NOTE:
Bandwidth management must be considered for the use of high-speed USB
peripheral devices such as web cameras and flash drives. To prevent excessive USB
traffic for Layer 2 support of multiple remote devices, only one high-speed USB device
can be used regardless of the number of remote extenders. Multiple high-speed USB
devices should not be connected to multiple remote extenders.
For Layer 3 transport, one local (DEVICE port) connection supports only one remote
(HOST port) connection. Layer 3 supports USB 2.0 transport of data across VLANs.
To configure USB routing, use the web interface or SIMPL Windows as discussed in the
following sections.
