Installation Guide for the AV Bridge 2x1 Presentation Switcher

Installation
This section covers how to install and connect the product. It also provides safety information and other
guidance related to installing the product.
Note
This product is intended for installation and use only in environments where all RS-232 and PoE/PoE+
connections originate within the building.
Or in UL's preferred phrasing...
PoE-type networks connected to this equipment are for intra-building use only and should not be
connected to lines that run outside the building in which this product is located.
Don’t Void Your Warranty!
Caution
This product is for indoor use. Do not install it outdoors or in a humid environment without the appropriate
protective enclosure. Do not allow it to come into contact with any liquid.
Do not install or operate this product if it has been dropped, damaged, or exposed to liquids. If any of these
things happen, return it to Vaddio for safety and functional testing.
Cabling Notes
Use Cat-5e or better cable and standard RJ-45 connectors (568B termination). We recommend using high-
quality connectors and a high-quality crimping tool.
Caution
When building cables for Vaddio products, do not use pass-through RJ-45 connectors. If
they are crimped incorrectly, they can cause intermittent connections and degrade signal
quality. Incorrectly crimped pass-through connectors can also damage the connectors on
the product, which will void your warranty.
Intact – will make reliable contact
with cable connector
Damaged – Bent contact fingers
will NOT make reliable contact
with cable connector
Use Cat-5e or better cable. We recommend using high-quality connectors and a high-quality crimping tool.
We recommend shielded cabling if the cables will be coiled, run tightly with other cables, or placed close to
sources of electromagnetic interference such as power lines.
Caution
Check your cables. Connecting a cable to the wrong port or using the wrong pin-out can result in equipment
damage and will void the warranty.
Pro Tip
To prevent tragic mishaps, label both ends of every cable.

Installation Guide for the AV Bridge 2x1 Presentation Switcher

Basic Connections
This diagram shows a basic installation. Cameras or other HDMI sources may be used for both HDMI
inputs. The AV Bridge 2x1 does not power the speaker(s). The HDMI output displays video from the
selected source; the picture-in-picture (PIP) is from the video source not currently selected – a camera,
laptop, or other video source.
6
Installation Guide for the AV Bridge 2x1 Presentation Switcher

Basic Connections for Conferencing
Add a laptop and a second HDMI display for conferencing.
In this diagram, the laptop connects to the room's main display, which shows the far-end video from the
soft conferencing application on the laptop. (In contrast to the previous diagram, our friend at the podium is
on the far end of the call.) The soft conferencing application manages the PIP(s) in this image. The display
connected to the HDMI output shows near-end video.
The HDMI output from the AV Bridge 2x1 goes to a "confidence display" showing near-end video only. The
image on this display is used as the near-end PIP on the main display. If the PIP is enabled on the AV
Bridge 2x1, this is part of the image that others in the conference will see, and the room's main display
shows a PIP within the near-end PIP.
Using Dante Devices with AV Bridge 2x1
The AV Bridge 2x1 presentation switcher is compatible with Dante audio products. These products
connect to the AV Bridge 2x1 over the network.
To work with Dante devices, you will need to download and install the free Dante Controller application
from Audinate Pty. Ltd.:
www.audinate.com/products/software/dante-controller
Things to know about Dante Controller:
nDante Controller does not work over Wi-Fi or across subnets. Your computer must be on the same
subnet as the Dante devices you need to work with.
nDevice names and IP addresses shown in Dante Controller do not match the corresponding information
shown in Vaddio devices' web interfaces.
nDante Controller allows you to rename devices, so you can make their identifying labels match what's
displayed in the Vaddio web interface.
Audinate provides information, training, and documentation for Dante technology on their website.

Troubleshooting and Care
If the equipment does not power up as expected, use this table to determine whether to call Vaddio
Technical Support.
Note
If the equipment behaves in a way that suggests even a remote possibility of a bad cable, please try a
known good cable with the same pin-out. Factory-made cables can be defective. Cables can appear to be
good but only work part of the time. A cable may pass a standard continuity check but be unable to pass
enough power to the connected device.
Crimping tools can crimp unevenly, contacts can break internally, and individual conductors in the cable
can break inside the jacketing material. Any of these can result in a cable that passes a continuity check
but does not work reliably.
(The author would like to confess having made more than a few almost-good cables. It happens.)
Power Issues
What is it doing? Possible causes Check and correct
Nothing. The buttons do not
light up.
Power is not connected. Check the connections from the wall
outlet to the PoE+ power injector and
from the power injector to the device.
The wall outlet is not active.
(Check by finding out if it
powers something else, such
as a laptop or phone charger.)
Use a different outlet.
The device or its power injector
is bad.
Contact your reseller or Vaddio
Technical Support.
Unresponsive camera (no
video, unable to control the
camera, or both)
A cable is connected to the
wrong port.
Check and correct cable connections.
Acable is bad. (This can even
be a problem with factory
cables.)
Check using a known good cable with
the same pin-out.
There is a problem with the
camera.
Refer to the troubleshooting information
in the camera manual.

A high-speed USB protocol, capable of handling high-quality video and audio as in conferencing applications. USB 3
products should be connected to USB 3 ports; performance may be degraded otherwise.
USB playback
Audio from other sites (far-end audio) in a conference call.
USB record
Audio from your site (near-end audio) in a conference call.
UVC drivers
(Universal Video Class) Standard USB video drivers used by Vaddio cameras. They're the reason your computer doesn't
have to stop and download a driver when you connect your new Vaddio USB camera to it.
UVC extensions
Controls in UVC drivers to allow participants at the far end of a conference to control your camera, if it processes UVC
commands. The administrator may choose to disable these.
