INTRODUCTION
Visionary Solutions 4K UHD over IP cinema quality, ultra-low latency [~1 frame - visually lossless] encoder and decoder bypass the
constraints of traditional switch matrix distribution systems by harnessing the flexibility and scalability of converged IP networks.
With the growing demand for 4K UHD video, professional AV designers and IT directors–in an increasingly converged AV/IT
environment–can use Visionary Solutions products as an alternative to conventional distribution systems.
Visionary Solutions brings the power of Dante™ enabled connectivity to video. For Installed AV professionals, the impact of Dante™
connectivity has been a game-changer, enabling fast, easy, and economical digital networking of multi-channel audio over IP.
Wouldn’t it be great if there was a Dante™ solution for video? Introducing PacketAV Duet-2 from Visionary Solutions.
PacketAV Duet-2 is nothing short of a paradigm shift for networked AV. True convergence is finally here; a single platform to
support Dante™ and Video over IP. Integrate 4K UHD video over IP into your Dante™ enabled audio network and bypass the
constraints of traditional switch matrix systems by harnessing the flexibility and scalability of converged IP networks.
Visionary’s PackeTV® and PacketAV® products can be deployed on any industry standard IP network. They can be used on existing
enterprise IP networks or on a physically separate parallel network [private network] to offload traffic, using the same network
protocols, methods, and devices but without intermingling video traffic with data or voice, and with equal ease of installation.
An encoder is connected to an [HDMI] AV source signal [a camera, STB, media player, PC or server, BluRay player, or digital signage
player, etc.]. The signal is converted into a packetized network stream that is compatible with off-the-shelf IGMP enabled Gigabit
Ethernet (GbE) switches (Jumbo Frames enabled). Using an existing CAT 5/6 infrastructure, users can connect CAT 5/6 to any decoder
anywhere on the same GbE network. The decoder takes the IP packets received over CAT 5/6 cables, converts them back into an
HDMI signal connecting directly to a display, delivering visually lossless video along with USB over IP (KVM) and RS-232 over IP
controls. A signal from any encoder can be sent to any decoder on the same network. The signals can easily be controlled with our
Vision Lite software to create different outputs on the display side, including video wall or matrix switching.
NETWORK AV INFRASTRUCTURE PREREQUISITES
This section is intended to provide a basic understanding of applicable networking technologies and the infrastructure requirements
needed for a successful Visionary Solutions Duet-2 system installation, and to ensure a rapid deployment and seamless integration.
Many network issues can be minimized or solved before they occur with appropriate knowledge and proper planning.
The Duet-2 will work with most non-blocking, IGMP with IGMP Snooping, 8K or better Jumbo Packet 1GbE network switches. At
least one layer-3 switch with IGMP-query capability is required. For PIM (multicast routing) of Duet-2 video streams, the network
switches would need to be capable of PIM (Sparse, Dense, or Sparse-Dense).
Do not connect any encoders or decoders to aswitch until the switch is configured for multicasting and IGMP Snoopingis enabled.
Check with your switch manufacturer for the default configuration settings.
NETWORK PROTOCOLS
All data on a network is encapsulated in packets, according to the TCP/IP protocols. Data packets are routed through the network to
their destination(s) by switches using information in the header of IP packets. Transmission can be unicast or multicast. Unicast
transmissions are point-to-point, from a single source to a single destination. Multicast transmissions originate from a single device
and are received by a group of devices on the network, according to the Internet Group Management Protocol (IGMP). Multicast
transmission is ideal for bandwidth-intensive application such as media distribution as it allows for efficient use of network
bandwidth. Only a single copy of the data is distributed to multiple destinations. On the other hand, unicast distribution of media to
multiple destinations is an extremely inefficient use of network bandwidth because duplicate copies of the data are sent, point-to-
point, from the source to each destination. Duet-2 devices make use of the multicast protocol.
More information concerning IGMP may be found here at:

DUETE-2/DuetD-2 USER MANUAL
NETWORK AV INFRASTRUCTURE PREREQUISITES
There are two ways to implement multicast routing when using our equipment:
• IGMP (Internet Group Management Protocol): Allows video streams (groups) to be dynamically routed only to those ports
requesting the video stream. The IGMP feature prevents the multicast video traffic from flooding the network and can
significantly reduce traffic in a layer-3 network. This is the recommended setting for our equipment.
• PIM (Protocol Independent Multicast): Functions independently of IP routing protocol. PIM Dense Mode (PIM-DM) is less
preferred for this application because it floods the network using unicast routing protocols to build routing tables. For more
information, visit: http://docwiki.cisco.com/wiki/Internet_Protocol_Multicast#Protocol-Independent_Multicast.
NETWORK REQUIREMENTS
For help determining the network requirements for your Visionary Solutions installation, please contact [e-mail].
POWER OVER ETHERNET (POE)
Power over Ethernet (PoE) is a system that uses an PoE Ethernet switch as a power source to provide both electrical power and data
over a single cable to devices on a network, such as the Duet-2 devices. This reduces the number of cables and power supplies that
are required to power the devices in the network. The result is lower cost, less downtime, easier maintenance, and greater flexibility
for the network installation.
When selecting a PoE power supply scheme, is it important to select a PoE Ethernet switch that is capable of providing enough
power per port, as well as total power to accommodate all devices simultaneously. You should plan on the maximum available PoE
power per port for Duet-2 (15.4W). In some operating conditions less power will be demanded per Duet-2, call Visionary Solutions
for details.
To calculate the number of devices that can be used on a PoE Ethernet switch, divide the total PoE power capability of the switch by
the power required for each port and round down. For example, many PoE Ethernet switches can provide up to 370W of DC power. If
each port needs 15.4W of power, a switch can supply power to a total of 24 ports.
Examples:
• A Cisco SG300-52P has a PoE power output of 375W and the ports require 15.4W: 375 / 15.4 = 24.35. Therefore, 24 devices can
be powered by this switch.
• A Cisco SG300-52MP has a PoE power output of 740W and the ports require 15.4W: 740 / 15.4 = 48. Therefore, 48 devices can
be powered by this switch.
Some switches can only supply PoE power to a certain number of ports. If it is necessary to use this type of switch, PoE injectors can
be used or a local power supply can be provided for the switch, or you may need to disable the detection of the PoE for those ports
in the Ethernet switch.
Exceeding the PoE switch limit can cause erratic behavior on the network system. The PoE switch cuts power to prevent overloading,
which may cause units to reset at seemingly random intervals.
PoE specification standards are:
• IEEE 802.3-2008 provides up to 10W of DC power.
• IEEE 802.3af provides up to 15.4W of DC power. Only 12.95W is assured to be available at the device.
• IEEE 802.3at, known as PoE+ or PoE plus, provides up to 32W of DC. Only 25.5W is assured to be available at the device.
Class 0 devices comply with the PoE standard that provides up to 15.4W of DC power for each port. The real power draw is between
5-10W.
Class 3 devices comply with IEEE 802.3-2008 that provides up to 10W of DC power.
SWITCH SPEED
The DuetE-2 encoder will produce up to 800Mb/s of data. Therefore, 10 encoders will require 10 x 800MB/s = 8Gbps. Duet-2 requires
the switch to be GbE. Duet-2 technology is used to transmit visually lossless 8~10:1 compressed video up to 4K along with other AV
signals such as audio, USB, and control signals. For video alone, this means raw bandwidth of up to 800Mbps for 4K.

DUETE-2/DuetD-2 USER MANUAL
NETWORK AV INFRASTRUCTURE PREREQUISITES
CHOOSING AN ETHERNET SWITCH
Switches must support these functions:
• Jumbo Frames (enabled)
• IGMP Snooping
• IGMP Querier
• IGMP Snooping Fast Leave
If the switches are used for multi-switch networking, they must also support PIM Routing (Sparse, Dense, or Sparse-Dense).
These features may be helpful as well:
• Dynamic multicast router port
• Forwarding unknown multicast to multicast router ports only
Any network switch should have a backplane capacity of at least (2 x 1000-Mbps x N) where N is the number of ports on the switch
passing the video traffic. For example, a 24-port switch where all available ports may be used to pass video traffic should have a (2 x
1000 x 24) = 48Gbps backplane. One channel of encoder video can be sent or received from each port in this switch example
although full bandwidth may not be used at any one time.
The maximum distance between devices is 100m (328ft) over CAT 5e (or better) cable. This distance can be extended in increments
of 100m (328ft) by using a gigabit switch as a repeater between devices. Copper to fiber adapters can extend the maximum distance
between devices up to 10km through the use of fiber.
Since different brands and models of switches perform differently when handling multicast IP packets, functional verification and
pressure testing are also recommended in any installation. Switches that perform well in smaller installations may not work well in
larger installations. Recommended configuration settings may vary based on your switch.
Visionary Solutions offers sample switch configuration files, optimized for Network AV, for certain switch brands/models for testing
purposes. Contact [e-mail] to obtain the files.
SWITCH GUIDELINES
1. Enable IGMP querying and snooping (set IGMP Version to IGMP V2 if the switch is capable). To enable the transmission of a
source to multiple destinations, Duet-2 devices make use of multicast. The default behavior of a layer-2 switch is to broadcast
those packets, which means that every packet will be transmitted to all possible destinations. IGMP snooping checks IGMP
packets passing through the network, picks out the group registration, and configures multicasting accordingly. A layer-2 switch
supporting IGMP Snooping can passively snoop on IGMP Query, Report, and Leave (IGMP version 2) packets transferred
between IP multicast routers/switches and IP multicast hosts to determine the IP multicast group membership. This is why any
network switch used with Duet-2 must support IGMP Snooping. Our 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 the receivers that want to
receive them.
IGMP Snooping is used to identify multicast IP packets, assign IP packets into multicast groups so that the router only sends to
devices that want to receive the packets, establish membership in a multicast group, and register a router to receive designated
multicast traffic. Multicast filtering is achieved by dynamic group control management. Many switches have the IGMP Snooping
feature disabled by default and manual configuration is required. Often, checking the Enable IGMP Snooping option is the only
setting needed to enable IGMP Snooping. Implementing IGMP Snooping is vendor specific and additional configuration is often
needed.
IGMP Snooping Querier is used to send out group membership queries on a timed interval, retrieve IGMP membership reports
from active
members, and update the group membership tables. The Leave Group packet is sent when a device wants to leave a
group.

DUETE-2/DuetD-2 USER MANUAL
NETWORK AV INFRASTRUCTURE PREREQUISITES
Because multicasting video traffic can flood a network and significantly reduce the flow of traffic, it is important to ensure that
your
network infrastructure and backbone switches support IGMP Snooping so that your core network is able to ignore the traffic
streams multicasting can generate. By default, all multicast traffic should be blocked until requested by a multicast
group
member.
Without IGMP Querying/Snooping, multicast traffic is treated in the same manner as a broadcast transmission, which
forwards packets to all ports on the network. With IGMP Querying/Snooping, multicast traffic is only forwarded to ports
that
are
members of that multicast group. IGMP Snooping generates no additional network traffic, which significantly reduces the
multicast traffic passing through your switch.
Note: Some switches require that the routing table be pre-loaded so that the switch does not have to interrogate each IP packet to
determine its
destination. Static routing can be used to route multicast traffic. Protocols similar to Generic Routing Encapsulation
(GRE) can be used to
encapsulate multicast packets in unicast wrappers for point-to-point transmission between switches, and
when the packets arrive at the destination IP address, the unicast wrapper is removed.
2. Enable Fast Leave. The switch may also support IGMP Snooping Fast Leave, which shortens the time takes for a device to leave a
group and be made available to join to a different group. A 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 another. Most switches have a Fastleave configuration option. When enabled, Fastleave speeds up
the time needed for a port assigned to one multicast group to leave the group and join a different multicast group. This
significantly reduces the video switching time. Always enable the Fastleave option when it is available.
3. Allow multicast traffic on all network ports through which video streams pass.
4. Ensure current Access Control Lists (ACLs) are not filtering multicast or control traffic.
5. Remove Flow Control and/or Storm Control on any network port passing the video stream.
6. Enable VLANs to separate video traffic from data and voice.
7. Enable Jumbo Frames.
8. Disable Green Ethernet (or efficiency mode). Some switches have the ability to lower the power consumption on the ports as a
“Green” feature. This can cause issues with bandwidth intensive devices (like our encoders and decoders).
IMPLEMENTATION CONSIDERATIONS
Duet-2 devices can be installed on a physically separate network or converged onto an existing GbE network. When implementing, it
is important to decide at the earliest stages of planning if the system will be integrated into the rest of the network or if it will reside
on a dedicated AV network. Each has its own advantages and disadvantages, but wherever possible we recommend the use
of a
dedicated AV switch. Using the existing network is of course possible–but it adds extra complexity to the installation and often
removes control of the networking equipment from thesite’s AV staff or installer.
The first thing to consider is how much control the install and site teams have over the network configuration. Do they have access
and clearance to change the managed switch configurations on the fly? Is the network administrator willing to make the necessary
changes to support multicast and IGMP traffic on their network? Will they allow the creation of a VLAN or change their existing
VLAN configuration to support the required configuration? If the answer to these questions is no, then it is highly recommended that
the system be installed on a separate dedicated network switch. If this is not an option, then a conversation needs to take place with
the network admin staff to ensure they are aware of the requirements.
INSTALLING ON A CONVERGED NETWORK
Figure 1 illustrates how Duet-2 endpoints can be installed on an existing (converged) network. When using an existing
infrastructure, dedicated VLANs are recommended to separate the Dante™ and video traffic from other network data. All switches
that will handle AV traffic must be 1 GbE capable per the specifications in Network Requirements.
Visionary Solutions recommends that all encoders be turned off before connecting to an existing network. Once connected,
encoders can be turned on one at a time to determine network impact.

INSTALLING ON A DEDICATED NETWORK
Figure 2 illustrates how Duet-2 endpoints can be installed on a dedicated network. A dedicated network is recommended for
transmitting AV over IP. We offer various models of preconfigured switches for resale to our partners. These switches are shipped
pre-configured for AV over IP from the factory. Please contact [e-mail] for more information.
Figure 2. Dedicated Network Diagram
SINGLE SWITCH NETWORKING
Single switch networking can be used when there are no more than 100m (328ft) from the central distribution point. Any network
switch should have a backplane capacity of at least (2 x 1000-Mbps x N) where N is the number of ports on the switch passing the
video traffic. For example, a 24-port switch where all available ports may be used to pass video traffic should have a (2 x 1000 x 24) =
48Gbps backplane.
MULTIPLE SWITCH NETWORKING
The maximum distance between devices is 100m (328ft) over CAT 5e (or better) cable. This distance can be extended in increments
of 100m (328ft) by using a gigabit switch as a repeater between devices. Copper to fiber adapters can extend the maximum distance
between devices up to 10km through the use of fiber.
When using multiple switches, we recommend at least 10Gbps bi-directional connections between switches.
• (Link Bandwidth)/(800Mbps) = Number of simultaneous streams across link for 4K and (Link Bandwidth)/(200Mbps) = Number
of simultaneous streams across link for 1080p.

Visionary, Network Audio Video

DUETE-2/DuetD-2 USER MANUAL
INSTALLATION AND CONNECTIONS (SYSTEM E XAMPLES )
• The maximum number of streams possible between switches = link bandwidth (10Gbps) / 800Mbps (for 4K) x number of
encoders (or 200Mbps for 1080p).
• For 4K streaming, the total number of streams (800xn) must be ≤ 10,000.
• For 1080p streaming, the total number of streams (200xn) must be ≤10,000.
DUET-2 LAN1 & LAN2 ETHERNET EXPANSION PORT
Duet-2 is equipped with a single main gigabit (LAN1)Port for 4K UHD Video, Dante™/AES67, Control, and Powered Device (PD). This
single Ethernet port is used for Video over IP and Dante™/AES67 audio embedding and de-embedding, with VLAN tagging capability to
separate Audio & Video network traffic as needed.
Duet-2 is also equipped with an Ethernet Expansion (LAN2)Port - Power Sourcing Equipment (PSE). This port enables network
connectivity for control and IP traffic pass-through to remote LAN devices (ex. displays, projectors, control touch-panels). The port
can also be used to daisy-chain multiple endpoints for easy video wall creation or extend distances to displays.
Power connected devices with PoE pass-through.
Duet-2 Encoders and Decoders only require standard PoE power (15w or lower), however, when PoE+ is supplied to the Main LAN1
port you can pass-through PoE power to devices connected to the LAN2 Ethernet Expansion Port.
When PoE+ is supplied to the LAN1 port, the UNIT.PSE_ENABLED status found at the bottom of the unit’s web UI Network tab will
display “Available.” When the Status window displays “Available,” use the drop-down menu to choose either TRUE or FALSE. When
set to TRUE, PoE will be supplied out the LAN2 Ethernet Expansion port.

ONE SOURCE TO ONE DISPLAY
In this basic installation scenario, sending video from a single source to a single display, a single encoder and decoder (point-to-
point) can be linked directly together or over a network. If linked directly, the CAT 5e (or better) cable linking the devices should not
run more than 100m (328ft).
The devices do not connect automatically and must first be configured through embedded web interfaces. This step requires a
connection to a network. Once the devices are linked on the network, they can be connected directly. See section Configuration.
Figure 4. One Source to One Display Diagram
ONE SOURCE TO MANY DISPLAYS
Sending video from a single source to multiple displays requires a network switch. A single encoder can be linked to multiple
decoders (point-to-multipoint) over a network. Implementing a one-to-many installations dramatically decreases the amount of
equipment required at the source location.
The encoder and each decoder can be located no more than 100m (328ft) from the switch.

The video wall configuration requires a network switch to display multiple video sources to many displays or a single display in any
combination of video streams. Multiple encoders can be linked to multiple decoders
(multipoint-to-multipoint) over the network.
The video wall configuration allows almost any number of sources and displays. Multiple switches can be linked by fiber, providing

NETWORK DISCOVERY
Discover your Duet-2 endpoints on the network.
By default, the encoders and decoders are shipped from the factory in DHCP mode with Auto IP Failover. In DHCP mode, each
encoder and decoder unit are automatically assigned a unique IP address by the DHCP server. If there is no DHCP server on the
network, the encoders and decoders (after about one minute) will “failover” to Auto IP mode where each encoder and decoder unit
assigns itself a unique IP address within the range of
169.254.1.0–169.254.254.255, with a 255.255.0.0 subnet mask and a gateway
address of 169.254.0.254.
To configure the units, you must access the web interface of each encoder and decoder using a computer.
In order to communicate with the Duet-2 endpoints, the devices must be on the same subnet as your computer. You may need to
change the computer’s network settings to accomplish this.

be automatically assigned a unique IP address by the DHCP server on the same subnet, allowing communication with the Duet-
2 endpoints.
• Method 2: Configure your computer with a static IP address within the defined DHCP range for your network (the subnet (VLAN)
defined by the DHCP netmask for your network). Choose Use the following IP address. Enter an IP address then click OK. To
avoid address conflicts, enter a static address that is not in the range of addresses that will be given out by the DHCP server. For
example: If the DHCP range = 192.168.1.100 –192.168.1.150 and netmask = 255.255.255.0, you can assign 192.168.1.151.
To set up your computer to communicate with endpoints that are using Auto IP:
• Method 1: If there is no DHCP server on the network, a Windows PC will “failover” to Auto IP in a similar way as the encoders
and decoders. Accept Obtain an IP address automatically (the default). After about one minute the computer will assign itself a
unique IP address within the range of
169.254.1.0–169.254.254.255, with a 255.255.0.0 subnet mask, allowing communication
with the encoders and decoders on the network that are also assigned IP addresses via Auto IP.

• Method 2: If the computer already has a statically-assigned IP address:
1. Click Advanced > Add.
2. Click Add to enter a unique IP address within the range of 169.254.1.0–169.254.254.255, with a subnet of 255.255.0.0.
•Method 3: Configure the computer with a unique static IP address within the range of 169.254.1.0 –169.254.254.255, with a
subnet of 255.255.0.0. If your address is not unique conflicts will occur.
There are multiple ways to discover (find the assigned IP address) the encoders and decoders on your network.
1. Use the Vision Lite application to auto-discover units. RECOMMENDED – refer to section Vision Lite.
2. Look at the DHCP server list of assigned IP addresses.
3. Use avahi-browse (requires avahi-daemon to be running) to find the unit IP addresses.
4. Using a Linux operating system (OS) on the network, ping 226.0.0.19 from the same subnet (VLAN) as the unit to return a list of
assigned IP addresses. On a Windows OS, the ping command only displays the first responding address.
5. Use nmap to scan for Visionary Solutions MAC Addresses.
6. For decoders only: Connect to the network via HDMI to a display. The IP address displays on the bottom right of the Boot up
screen image on the display device when there is no source connected.
Once discovered, you can use the embedded web interface on each encoder and decoder unit to configure and change the network
settings. To log in to the web interface, enter the unit’s IP address in a web browser for the URL OR click the IP address in the Vision
Lite application Configuration page. Log in with
username =admin password=admin.

CONFIGURATION
CONFIGURING ENCODER AND DECODER IP ADDRESSES
As previously mentioned, by default, the encoders and decoders are shipped from the factory in DHCP mode with Auto IP Failover.
For a permanent installation, and to ensure system consistency, it is recommended to configure all of the encoders and decoders
with static IP addresses.
Important: IP configuration changes must be done correctly to avoid any communication disruptions with the units. Communication
with the Vision Lite Server and the computer that the application resides on is dependent upon the computer being in the same IP
address range as the encoders and decoders on the network. Therefore, before making any IP address changes to the units, we
recommend having two statically-assigned IP addresses on the computer.
When using DHCP, configure the first static IP address to an address within the defined DHCP range for your network (the subnet
(VLAN) defined by the DHCP netmask for your network). Be sure that the static address you assign is not in the range of addresses
that will be given out by the DHCP server to avoid address conflicts. For example: If the DHCP range = 192.168.1.100 – 192.168.1.150
and netmask = 255.255.255.0, you can assign 192.168.1.151.
When using Auto IP, assign an address within the range of 169.254.1.0 – 169.254.254.255, with a 255.255.0.0 subnet mask.
AND
Configure a second static IP address in the range of the IP addresses you are planning to assign to the units.
Assign new IP addresses to the encoder and decoder units as follows:
1. Access the web interface for the encoder or decoder unit.
2. Log in with username= admin password=admin.
3. Click the Network tab.
4. Set IP.MODE to Static.
5. Set the IP.ADDRESS. Example: 192.168.1.45
6. Set the IP.NETMASK. Example: 255.255.255.0
7. Set the IP.GATEWAY. Example: 192.168.1.1
8. Set the IP.DNS_SERVER (optional). Example: 4.2.2.1
9. Click Save to save the new settings. The unit will automatically reboot.
The unit is now configured with the new network settings.
VLAN TRUNK MODE
The Duet-2 utilizes a single physical network interface for audio, control, and video. To separate the AV stream from the Dante
network audio, and control data, the Duet-2 is capable of enabling its network interface as a trunk port. This allows for tagging the
AV stream traffic for one VLAN and tagging the Dante network audio for a separate VLAN.
Enabling VLAN trunk mode for Duet-2 as follows:
1. Access the web interface for the Duet-2 unit.
2. Log in with username =admin password =admin
3. Click the Network tab
4. Set VLAN.TRUNK_MODE to TRUE

5. Set IP.VLAN_TAG_STREAM to the VLAN configured for the AV stream Example: 1
6. Set IP.VLAN_TAG_DANTE to the VLAN configured for Dante network audio. Example: 2
7. Set IP.VLAN_TAG_EXPANSION to the VLAN configured for control data. Example: 3
8. Click Save to save the new settings. The unit will automatically reboot.
The unit is now configured with the new network settings.
Important: The port on the network switch the Duet-2 is connected to must also be configured as a trunk port and must be a tagged
member of assigned VLANs.
Once the initial configuration is complete, you will be primarily using the Vision Lite matrix routing control software (or other third-
party control systems) to route the encoder and decoder streams to each other. When using these systems, the STREAM.HOST
setting, described in the following sections, is automatically updated each time a routing/switch occurs.
In the absence of a control system, it is still possible to manually configure the stream settings. The instructions are included
below.
CONFIGURING STREAM SETTINGS (MANUALLY)
UNICAST MODE
The term unicast is used to describe a configuration where information is sent from one point to another point. A unicast
transmission sends IP packets to a single recipient on a network. It is possible to have multiple encoder and decoder units connected
in a system. However, in unicast mode, an encoder unit can communicate with only one decoder unit at a time (see Figure 1).
1. Access the web interface for the encoder and decoder units that will be using unicast mode.
2. Log in with username =admin password=admin
3. Click the Configuration tab.
4. Set STREAM.MODE to Unicast.
5. On the encoder:
a. Click Save on to save the new settings. The unit will automatically reboot.
6. On the decoder:
a. Set STREAM.HOST to the IP address of the encoder that the decoder is tuned in to.
b. Click Save on to save the new settings. The unit will automatically reboot.
The units are now connected in unicast mode.
MULTICAST MODE
The term multicast is used to describe a configuration where information is sent from one or more points to a set of other points. For
example, a single encoder unit can transmit data to multiple decoder units. In addition, if multiple encoder units are used, each
encoder unit can transmit data to any decoder that is not already receiving data from another encoder unit (see Figures 2-5).
Note: Visionary’s DuetE-2 encoders default to a multicast stream based on their serial numbers. We recommend that you leave this
as the stream address unless the range (225.168.0.0–
225.169.255.255) conflicts with other multicast streams on your network. If you
need to change the multicast stream address, please contact [email protected]m for assistance.
