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 once they have been connected for the first time with 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, 50Mbps 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 unshielded cables 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 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 via the Aurora IPBaseT Manager server, either running on a
PC or on a dedicated control appliance (RXS-1). It can also be controlled from other Aurora control products or 3rd party
control systems with the available VLX API. In order to obtain the VLX Server API commands you must be dealer status
otherwise an NDA is required and is at the discretion of Aurora. The VLX can also work without the server as a 3rd party
control can communicate directly to each unit to change settings or make routes. This makes the VLX extremely flexible
and for low cost smaller systems very cost effective.
Controlling the VLX for Redundancy
Multiple control systems can run on the same network for redundancy. It is important only one communicates at any
given time or incomplete commands may occur between units communicating simultaneously.
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.

12
USERS GUIDE
www.auroramm.com
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 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.
USB Network Bandwidth Requirement:
⚫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 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:
⚫Still frame < 216Kbps
⚫Web browsing 70~100Mbps (1920x1080) 60fps
⚫YouTube full screen 21~132Mbps (1920x1080) 60fps
⚫Movie average 165~315Mbps (1920x1080) 60fps

APPLICATIONS
Example 1: Retail Store Display Distribution
Retail Store Display Distribution
The DXE-218 is the perfect fit for HDMI distribution of the same signal up to 8 displays or more if
daisy chained together. The integrated per port downscaling allows for compatibility with lower cost
1080p displays that normally cannot handle a 4K signal. This saves money by eliminating the need
for external scalers.
Retail stores typically display the same content on several screens for consumers to compare the
difference between the brands and models. These screens do not always have the same resolution
capabilities. The DXE-218 creates the compatibility with one 4K source.
The ability to do CEC control per port allows the DXE-218 to control the on/off and source inputs
independently on each screen. This can all be done remotely. This feature assures all the screens are
on when they should be and off when the store is closed as saving power and screen life is important.
Remote diagnostics is important too. The DXE-218 through the LAN can report what ports are
connected and read back the EDID of each screen to know what display is connected.
A clean install for serviceability is a must. PoE eliminates all external power supplies and even allows
for remote power cycling of the DXE-218. The DXE-218 is firmware upgradeable through the LAN
and it has a simple method for changing the IP address when units are swapped, especially when
more than one is connected.
The DXE-218 is the ultimate 8 port splitter advancing the technology to the next level.

APPENDIX 1
Troubleshooting
It is advisable to make certain all units are using the latest firmware before troubleshooting. Also make sure all network
connections are operating are 1G.
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 web server 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.
⚫Look at status LED and make certain unit is linked. The enter button on the front changes the link status.
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.

USERS GUIDE
www.auroramm.com
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.
⚫Ensure the proper serial control mode is selected (SoIP)
Routing a source to multiple displays is tearing
⚫Check network switch is properly configured for IGMP and supports Jumbo packets. VLX requires
Jumbo/MTU Packet of 8192 or better for full 4K video streaming.
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 utilized 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.
Displays not showing same video frame as others
⚫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.
