1. Introduction The ATEN VE8900 / VE8950 HDMI over IP Extenders deliver visually lossless 1080p/4K AV signals with low latency over long distance via a standard Gigabit network. The purpose of this guide is to ensure that installation project managers and site administrators are aware of ATEN’s best practice guidelines for appropriate network structure and configuration for use with the VE8900 / VE8950 HDMI over IP Extenders.
2. VE8900 / VE8950 Series The VE8900 / VE8950 provides an effective, easy-to-use and economical digital signage solution with many unique features that directly address the challenges system integrators encounter when implementing AV over IP systems. Limitless flexibility and scalability: ...
Mounting/Installation All ATEN products should be mounted so that the logo and text printed on the unit is correctly aligned. This will allow for the optimal airflow through the product. As already stated the vents should not be obstructed with adequate clearance. Units should be secured using suitable fixings.

Source & Display Settings ATEN VE8900/8950 uses the highest quality encoders available to provide visually lossless compression over a large number of displays. However, the compression can only be as good as the source content that is put in. VE8900/8950 uses proprietary compression and supports HDCP 1.4.
4.1. Choosing the right Cable Testing & Certification ATEN products are manufactured and tested to the highest standards but the best installation environment is paramount to successful installation. The only way to guarantee if the installation is fit for purpose is to test and certify the cables. All IT cable companies will certify cables throughout a network as standard, yet they are passing a fraction of the data in short bursts.
4.2. Choosing a Network Switch This section provides various general and specific recommendations for switches to use with VE8900 / VE8950. However, there is no substitute for testing in real world situations. If you are in doubt about which network switch to use, the safest approach is to select one from the list of recommended switches below.

Layer 2 Switch: Packets are examined and forwarded using only the MAC address. If you have a small central network, a layer 2 switch should do the job. If the network is exclusive and will only transmit the bandwidth of VE devices, layer 2 switches with the correct settings can get the job done effectively. Further Considerations Number of ports: Choose a switch that has enough ports to match the number of VE devices you will be installing.
Recommended Switches The following models have been tested and found to produce favorable results: Manufacturer Model D-Link DGS-1510 SG300 Cisco Catalyst 2960-XR Catalyst 2960-X GS724T Netgear M4300-28G M4300-52G 5120 Series Edgecore ECS-4120-52T Networks 4.3. Planning Network Architecture Build Strategies For optimum performance, the VE extenders require high amounts of data to be transferred across a network;...

Considerations: Use a flat cascaded layout (basic line cascaded structure) and avoid a tree or pyramid structure Limit cascades to two levels Install network switches as near to each other as possible Minimize the distance of all connections ...
Cascaded Switch Networking If more devices are required, it is recommended to cascade switches. Assuming a typical transmitter bitrate of 150~500Mbps, we recommend using network switches with 10Gbs connections for bidirectional data flow between the core and extended switches. 4.4 Network Setup Examples One Transmitter to One Receiver A single transmitter and receiver can be linked directly or via the LAN, to send video from a source to a display in another location.

One Transmitter to Multiple Receivers Using VE8900 / VE8950 for one-to-many installations dramatically decreases the amount of equipment required at the source location, each transmitter can be located up to 100m/355ft from the switch. Scenario A (with Ethernet switch) Scenario B (without Ethernet switch) ...
4.5. Configuring the Network Switch IGMP and Other Settings Configuring the switch correctly will pass data more efficiently, allowing a better stream across the network to each VE device. The following settings will help optimize your network traffic through a switch: ...
