System Installation
The installation phase should ensure that the interaction among designer, installer,
programmer, and end user is considered in all installation decisions.
Endpoint Installation
Each DM NVX endpoint has unique installation requirements that depend on the
following:
• Copper or fiber network connectivity of the endpoint
• Surface-mountable or card-based endpoint
• Configuration of a combined encoder/decoder endpoint as a transmitter or a
receiver or whether the endpoint is to switch dynamically between modes
• Additional local HDMI inputs that require configuration
• Use of source autoswitching or external switching control
• Additional audio sources that require encoding
• USB device or host functionality
• Whether the endpoint is part of a video wall or goes to multiple identical displays
• Requirement for serial or IR control or both
A Crestron touch screen can be linked through a spare LAN port on an endpoint.
An audio input/output port can be repurposed to be a balanced line input for external
analog audio input or for line output to a speaker system at the endpoint.
The endpoint features and attached devices can be configured through programming or
through the web interface.
Depending on the location of the control processor, serial and IR control of endpoint
devices may be routed directly from that control processor. Access to HDMI and USB
inputs and outputs can be provided through Crestron HDMI breakout devices for
tabletops and walls.
Surface-mountable endpoints can be mounted in any orientation as required. Typical
locations for surface-mountable endpoints include inside closets and drop ceilings,
underneath tables, and in podiums. The specific location is determined by the
following factors:
• Length of HDMI and USB cable runs
• Location of display and audio devices, network connectivity, power for the device,
and physical security requirements
Serial and IR connectivity can be run at longer lengths and are typically not drivers of the
endpoint mounting location.
