INTRODUCTION

About

The VLX Series provides one of the most advanced IP Streaming solutions on the market

utilizing Aurora’s IPBaseT® technology, which synergizes various IP/AV standards to

work together as one. It is the industry’s first 4K UHD transceiver with only 1.5 Frame

(25ms) latency and visually losses compression. Using a transmitter (encoder) and
receiver (decoder), respectively, used to be the standard – until now. The VLX Series box
or wall plates can be set up as either one to make installation, inventory, and
troubleshooting easier.

Another industry first is the option slot to add other IP capabilities, like Dante® audio, for
a more complete, distributed system. Audio, video, data, and control can be sent securely
to one or many units using off-the-shelf 1G RJ-45 Ethernet switch. When the VLX is set
up to be a transmitter, the 2 HDMI inputs (VLX-TC1-C, VLX-TCW2H-C) or VGA/HDMI
inputs (VLX-TCW2V-2) become a source switch and the HDMI output becomes a
potential loop out. When set up as a receiver, a user can select the local HDMI inputs or
an IP source. Seamless switching of the sources further enhances the presentation.
Regardless of how the VLX is set up, the audio can be de-embedded at any location,
and/or be sent to or received from a Dante® enabled device. The USB is also flexible,
working as a KVM and/or a high-speed data transfer (480Mbps) for memory sticks. Each
VLX USB feature can also be set as a host or a device. To keep the system friendly, an
OSD and integrated web server are available for easy navigation and setup of features.

Digital signage, education, corporate, and residential are just a few markets which benefit
from the flexibility and low cost of the VLX Series.

UNDERSTANDING THE BASICS

Direct Connection with No Ethernet Switch

The VLX Series is designed to automatically tunnel the video, audio, USB, RS-232, and IR if they are
connected without an Ethernet switch.

1GbE Ethernet Switch

It is important to use a non-blocking IGMP 1GbE switch with IGMP snooping and Jumbo packets. The
size of the switch is based on the requirements of the project. With this in mind, consider if extra port
capacity is required for future expansion. If you run out of port capacity, you can always add another
1GbE switch in the future. The VLX, when set to encoder (TX), determines the bandwidth that will be
multicast across the network. 24bit 4k@30Hz can peak at about 850Mbps and 425Mbps for 24bit
1080p@60Hz (Data Rate in bits per second = Color Depth x Horizontal Resolution x Vertical Resolution x
Frame Rate) but typically averages 218Mbps for full motion 4K video. This does not include the 10/100
LAN, 480Mbps USB, RS-232, IR over the same transmission if required. If 10 units are set as encoders,
and 4K@30Hz is the desired video resolution, then 8.5Gbps of bandwidth will be required if uplinked to
another switch. If the available bandwidth between the two 1GbE switches is less than 8.5Gbps, then
packets will drop and information will be lost. It is also a good idea to take into account overhead and
assume 15% bandwidth loss to play it safe. Since each port is bi-directional 1Gbps, it enables any port to
be used as an encoder or decoder. The AV industry is used to standard distribution topology limitations of
4x4, 8x8, 16x16, etc. With networked based video distribution, a 48 port 1GbE switch as an example can
be 24x24, 1x47, 47x1, 12x36, etc. If bandwidth is tight the VLX has the ability to cap the bandwidth at
200Mbps which will work well for most applications. (see Ethernet Bandwidth Usage section for more
detailed information)

Network Infrastructure

The raw network cabling as well as the patch cables are as important as the switch. When using copper,
CAT5e, 6, or 6a cable is preferred for optimal performance and is important to follow the standard rules
for running Ethernet cables. No sharp bends, coiling, putting near power lines, grouping tightly together
with other LAN cables, etc. Shielding is not necessary but can be used for noisy environments.

Isolated Network or Users Network

When discussing a networked based video solution, many times it is assumed it has to be on the client’s

network. This is not true. The application determines the type of network to be used. For example, if it is
simply being used as a typical AV matrix switch with no distribution throughout the facility, then a 1GbE

17

switch can be used just for that room. Just because it is Ethernet based does not mean it has to be used
on the main network. The Ethernet switch is simply used as the end point for all the cables and the glue
that holds everything together. In other words, it takes the place of the standard AV matrix switch
topology. If only remote control is required from the main network, then connect the 1GbE switch to the
main network and allow the control data between the 1GbE switch VLAN and the main network. Even if
the VLAN is part of the main network it does not mean you will use all the bandwidth. The purpose of
IGMP, is to only send the multicast data to the ports specified, which would be where the VLX units are
connected to. Non-blocking switch assures full bandwidth is available for all ports as required.

Controlling the VLX

To simplify control of the VLX, each unit can be controlled individually from the built-in web pages, Aurora
control products, or from a 3rd party control system with the available VLX API. In order to obtain the VLX
API commands you must be dealer status otherwise an NDA is required and is at the discretion of
Aurora. To make control even easier and more powerful, each unit has 3 Telnet ports. One for overall
control, one for RS-232 to create a virtual com port, and one for IR to create a virtual IR port using Pronto
IR commands. This allows a control system to use any RS-232 code already written to be 100%
compatible with the VLX as it only has to be sent to the Telnet port and not modified to fit inside another
protocol. This makes the VLX extremely flexible and very cost effective.

Controlling the VLX for Redundancy

Multiple control systems can run on the same network for redundancy. Each VLX unit can handle 50
simultaneous connections.

EDID and its Importance

One of the most forgotten setup procedures in AV systems is the EDID. The EDID comes from the
destination (display, VTC, recorder, etc.) and must be saved into the encoder and decoder HDMI input
ports. This allows the source (Blu-ray, computers, etc.) to know the capabilities of the destination. This
includes the audio type if any, video resolution and timing, color space, color depth, and more. If no EDID
is present an HDMI device will revert to lowest resolution in DVI mode which also means no audio. If the
wrong EDID is used, the image may look pink, green, or have no image at all. To make matters more
complex, if different destinations/displays are in use in a matrix configuration, then it is important to use
an EDID with a common denominator or only one or the other destination may work. In an ideal
installation, all the destinations should have the same capabilities for optimal performance. I this is not
possible a scaler may have to be implemented to assist in the compatibility.
For example, there are 2 displays one 1080p the other 4k UHD. If the EDID of the 4K display is used, the
1080p will not see an image if the source is capable of 4K. If the 1080p EDID is used, then both will see

18

the image but the 4K will never benefit from 4K content. In a situation where this is unacceptable, a 4K
scaler can be used on the 1080p screen to down scale the 4K content so the 4K EDID can be used and
the better screen can have a benefit. Note scalers do add frame latency and can affect image quality
based on the quality of the scaler. This is why it is always ideal to use destinations with similar
capabilities for optimal performance.

Audio can be impacted just as easily. If a destination is 6-channel surround sound capable and the other
destination is not, then the EDID from the 5.1 destination cannot be used, or there will be no audio on the
other destination. In most commercial installations, it should not be an issue to choose the lowest
common denominator, which is 2-channel audio, but in cases where you must have surround sound then
a down-mixer for the 2-channel destination must be used.

In some cases, a custom EDID could be created, as the audio and video are mismatched between the
destinations. This can occur for example, when one destination has 4K 2-channel audio and the other
1080p with multichannel surround sound. If the EDID of the 1080p destination is used, audio will not be
present on the 4K destination. If the 4K EDID is used, there will be no video present on the 1080p
destination. The only way to solve this issue, is a new EDID combining the common features. In this case
an EDID which is set at 1080p with 2-channel audio is the solution.

Videowall Capabilities

The VLX videowall mode has the ability to take in up to a 4K UHD signal and create a low latency high
quality videowall up to 8x8 in size. The way the mode works is by dividing the input resolution by the
amount of displays. For example, a 2x2 videowall will become four 1080p signals from a 4K UHD signal.
The VLX also has bezel compensation to create a seamless window pane effect.

Ethernet Bandwidth Usage

The VLX streaming bandwidth is dynamic with the compression a low fixed 8:1 compression. With no
USB activity and a still image fed into a decoder the VLX will use as little as 216Kbps of network
bandwidth. Maximum throughput is 820Mbps.

● When USB devices are attached but there is no activity, the network bandwidth requirement

is almost 0.

● For non-isochronous USB devices, network performance only impacts the performance of

the USB device. It won't impact USB devices' functionality.

● For isochronous USB devices (for example, USB audio), the network latency may impact the

19

functionality of this kind of device. If the network latency is too long, iso packets may be

discarded and causes audio glitch. It is important to use fast-leave high quality switches for

this application.

● For most of USB devices, the network bandwidth requirement will be almost the same as

what it takes on USB bus.

Typical Video Network Bandwidth:

● S till frame < 216Kbps

● Web browsing 70~100Mbps (1920x1080) 60fps

● YouTube full screen 21~132Mbps (1920x1080) 60fps

● Movie average 165~315Mbps (1920x1080) 60fps

APPLICATIONS

Example 1: VLX-TCW2 Configured as Transmitter to VLX-TC1 Configured
Receiver

When the VLX Series is connected point to point, no configuration is required, as the units will auto

identify and make a tunnel between both ends for the video, audio, RS-232, IR, USB, and Ethernet. With

the copper version a maximum distance of 100m (328ft) can be achieved.

40

Example 2: VLX Multi-Room

The VLX Series is perfect for multi-room applications with its flexibility. A nearly unlimited number of

rooms can share video, audio, data, and control in real-time. The scalability is only limited by the size of

the network switch and infrastructure.

41

Example 3: Matrix - Multiple VLX to Multiple VLX

The VLX can take the place of any typical card cage matrix system, adding flexibility and performance

never seen before. Even features like seamless switching is no longer a premium.

42

Example 4: Video-Wall

The VLX Series is capable of 4K video-walls. Up to 8x8 size can be created with 4K input.

43

Example 5: KVM utilizing USB 2.0

Command & Control and NOC centers are perfect for the VLX Series, especially with the USB 2.0 running

at a full 480Mbps. With the VLX it is no longer just keyboard and mouse but full USB peripheral routing

as well.

APPENDIX 1 Troubleshooting

It is advisable to make certain all units are using the latest firmware before troubleshooting.

VLX Web Server is not responding

 Make certain every VLX unit has a unique IP Address set for the webserver. Disconnect unit from

1G network and connect PC directly to 1G LAN and check to see if webserver appears in browser.
If not trying restoring defaults and try again. Repeat this for every unit. Another method is using the

server to issue commands to change the webserver IP settings over the 1G.

Display will not show a picture

 All devices are powered on.
 Unit is set properly for Decoder. LED status will show this.
 Check routing with built in web page of decoder.
 A picture is achieved when connecting the source directly to the display.

 Display is set to the correct signal source input mode using display’s remote. Example, switching

to HDMI 1 if HDMI 1 interface is connected to the RX via a HDMI cable.

 All the cables are qualified.
 The Switch supports IGMP snooping and this function is enabled.

Display has image with wrong color

 Make certain to learn the EDID from the display and save into each unit HDMI input ports.
 If different displays are used with the same source an EDID with a common denominator must be

used. For example, if on destination is 4K UHD and the other is 1080p and the 4K EDID is utilized,
the 1080p screen will not get an image if the source is 4K capable. In this case, it would be better
to use a 1080p EDID.

Audio not working

 Make certain correct audio path is selected. The VLX can choose between analog input and HDMI.
 Verify correct EDID usage. If EDID has 5.1 surround sound listed and display cannot do 5.1 there

will be no audio. Lack of EDID will also cause a source to output DVI which lacks audio.

 Check volume on display or amplifier

VLX RS-232 control is not working

 Check wiring for RX, TX, and Ground. (VLX 3.5mm Tip is TX, Ring is RX, Sleeve is GND)
 Check the baud rate of the unit.
 Confirm the protocol being utilized with a terminal program.

49

Routing a source to multiple displays is tearing

 Check network switch is properly configured for IGMP and supports Jumbo packets.

VLX Server is responding poorly

 Check network switch is properly configured for IGMP with snooping

Displays not showing same video frame as others

 If displays are different brands this can happen as depending on the scaler circuitry utiliz ed inside

the display and the amount of buffering used.

 If displays are different brands trying using same native resolution of the displays. Some displays

will not scale or use memory and just sync to the native signal.

Audio is different between displays or the analog output

 If displays are different brands this can happen based on the design. It is always ideal to use same

models for consistency or a central source for audio to keep in sync.

APPENDIX 2 Firmware Update

For the latest firmware updates please go www.auroramm.com

You must be signed up to the Customer Portal in order to download firmware with
instructions on how to update.

APPENDIX 3 Protocol

For the latest protocol please go www.auroramm.com

You must be signed up to the Customer Portal in order to download VLX protocol. The
protocol is only available to authorized Aurora dealers.

51

APPENDIX 4 Recommended Cabling

The VLX series uses industry standard CAT 5e, 6, and 6A cabling. Follow standard 1Gbps

network infrastructure when installing.

52

APPENDIX 5 Recommended Network Switches

The VLX will work with most non-blocking, IGMP, Jumbo packet 1Gbps network switch.

Layer 3 will allow more control, however, Layer 2 will work as well. It is highly

recommended to communicate with the representative of the desired network switch

brand to confirm configuration and capabilities. Below are some models that have been

tested with the VLX Series.

5.1 Switch Speed

The VLX Series requires the switch to be a 1GbE.
VLX Series technology is used to transmit visually lossless 8:1 compress video up to 4K
along with other AV signals such as audio, USB and control signals. For video alone, it
means raw bandwidth of about 218Mbps average/850Mbps peak for 4K and that is just
for audio and video. It is therefore easy to understand why the VLX requires 1GbE
network switches.

5.2 Packets Routing

To enable the transmission of a source to multiple destinations, VLX devices make use
of Multicast. The default behavior of layer 2 Ethernet switch is to broadcast those
packets which mean that every packet will be transmitted to all possible destinations.
This is why any network switch used with VLX Series has to support IGMP Snooping.
VLX end points use IGMP protocol to assign the end points into multicast groups and
the router uses IGMP snooping to efficiently route multicast packets only to receivers
that want to receive them.

Many switches have the IGMP Snooping feature disabled by default and manual

configuration is required. Often, a simple check mark near “Enable IGMP Snooping” is

the only thing needed to enable IGMP Snooping.
However, the implementation of IGMP Snooping is vendor specific and additional
configuration is often needed.

An Ethernet switch can be informed that a device wants to leave a multicast channel by
sending it a IGMP LEAVE GROUP packet. Once received, the time it takes for the
switch to apply the new configuration may vary from one switch to the other. Most
switches implement and include FASTLEAVE configuration option. When enabled, it
takes much less time for a particular port to leave a multicast group to assign the port to

53

a different multicast group. The end results are a noticeably shorter video switching
time. Aurora recommends to always enable the FASTLEAVE option when available.

5.3 Ethernet Switch Configuration

The following list includes all network switch configuration options that Aurora
Engineers have come across so far. Look for these or similar options when configuring
your switch.

1. Enable IGMP Snooping
a. Must be enabled

2. Enable IGMP Snooping on VLAN 1
a. Must be enabled when all ports default to VLAN1

3. Filter/Drop unregistered Multicast traffic
a. If not applied, the behavior of the switch will be to broadcast multicast packets

if the switch has no known destination for that packet.

b. Must be enabled if found

4. Unregistered Multicast Flooding
a. Must be disabled if found

5. Filter Unregistered Multicast (different wording than number 4 above)
a. Must be enabled if found

6. Enable IGMP Query

7. Enable IGMP Query on VLAN1

8. Set IGMP Version to IGMP V2
a. Must be set if found

9. Enable FASTLEAVE on port X
a. This is optional. Should be enabled, if found

10. Enable FASTLEAVE for VLAN1
a. This is optional. Should be enabled if found

11. Jumbo Packets should be standard function but if not it must be enabled.

5.4 PoE (Power over Ethernet)

The VLX Series uses around 6 watts of power, however, the PoE is unclassified for up
to 12.9 watts (15.4 Watts Total) as the USB on the VLX can supply up to 5 watts. When
selecting a PoE switch always make certain the power supply of the PoE switch is
proper to the port count (15.4W x qty of ports). For example, a 24 port PoE switch must
have at least 369.6 Watts (24 at 15.4W) for it to properly supply all 24 VLX devices.
Some switches can only supply a certain amount of ports with PoE. If it is necessary to

54

use a particular switch, then PoE injectors for the remaining ports can be used or the
local power supply for the VLX but you may need to disable the detection of the PoE for
those ports in the Ethernet switch.
