1. INTRODUCTION
This unit is part of a 4K UHD Multi-Function Extension system that allows
you to extend HDMI or VGA signals along with KVM using the TCP/
IP protocol over regular Cat.5e/6/7 network cable. This extendersupports the transmission of Ultra High-Definition signals (up to 4K@30Hz
YUV 4:4:4 or 4K@60Hz YUV 4:2:0) with audio and USB up to 100m on asingle cable. The transmission distance can be further extended (upto 100m per segment) by using gigabit network switches, allowing theuser to cascade the system without signal loss or introducing delay.
It is also possible to have the extension system's Transmitter operate
in multicast mode, allowing you to send a single AV signal to a large
number of Receivers within the same local network. Additionally, thatsame multicast signal can be used to create large multi-display video
walls with amazing simplicity. This system is perfect for both residential
and commercial installation environments.
This system also features bi-directional IR and RS-232 pass-through,analog line level in/out, and a microphone input (on the Receiver),providing the user with a variety of audio options. The USB functionality
allows the system to act like a remote USB hub which, when combinedwith the VGA input/output feature, provides a flexible remote KVM
platform. Configuration information is provided via On Screen Display(OSD) and control is by WebGUI, Telnet, and front panel controls.

2. APPLICATIONS• HDMI, VGA, USB, Audio, IR, and RS-232 extension• Broadcasting a system over a single Cat.5e/6 cable• Multimedia display on a large number of displays via multicast• Hotel or convention center display multi-monitor broadcast• Long distance data and video transmission via cascading• Distributed video matrix system• Distributed video wall system• Remote KVM control of a system

1 POWER LED: This LED will flash while the unit is powering on and will
illuminate solidly once it is ready to be used.

2 LINK LED: If the Transmitter has no network connection the LINK LED
will not illuminate. While the Transmitter is attempting to establish
a connection with a Receiver the LINK LED will flash. When theTransmitter has established a stable connection with a Receiverthe LINK LED will illuminate solidly.

3 RS-232 IN: Connect directly to your PC/laptop to send commands
to RS-232 devices connected to the Receiver. The baud rate isconfigurable, but the default baud rate is 115200.

Note: When the Transmitter is in multicast mode every connected
Receiver unit can send RS-232 commands to the Transmitterand commands sent from the Transmitter side will be sent to all
associated Receivers.

4 ISP SEL: For Factory use only. By default this is set to the right (awayfrom the RS-232 port) and allows normal RS-232 functionality.
Setting this switch to the left enables ISP engineering mode.

5 IR OUT: Connect to the provided IR Blaster to transmit IR signals sentfrom the associated Receiver to devices within direct line-of-sightof the IR Blaster.

6 IR IN: Connect to the provided IR Extender to extend the IR control
range of remotely located devices. Ensure that the remote being
used is within direct line-of-sight of the IR Extender.

Note: When the Transmitter is in multicast mode the IR signal is sent
to all associated Receivers.

7 IR WINDOW: Accepts IR signals from any standard remote control
and sends the signal to the IR Out on the associated Receiver.

4Note: When the Transmitter is in multicast mode the IR signal is sent
to all associated Receivers.

8 LOOPBACK/LINK: This button controls multiple functions:a Loopback: Press this button momentarily to toggle the VGA

Loopback function on and off, allowing you to locally monitor nonHDCP HDMI sources (1080p or below) for troubleshooting purposes.

b Video Link: Press and hold the button for 3 seconds to enable ordisable the Video Link. When the link is disabled and the Receiveris connected to a display it will show the system’s current IP andfirmware information.

c Reset to Factory Defaults: Press and hold this button whenpowering the unit on until both the POWER and LINK lights areblinking. Once both lights are blinking you can reboot the unit
and all settings will be returned to the factory defaults (Including
resetting the IP mode to auto, broadcast channel to 0, and thestreaming mode to multicast). A new IP address will be assigned
automatically within the 169.254.xxx.xxx address range.

9 MODE/Anti-DITHER: This button controls multiple functions:a Video Mode: Press this button momentarily to toggle the video

data streaming method between “Graphic” and “Video” modes.
“Graphic” mode is optimized for high-detail static displays and“Video” mode is optimized for full motion video.

b Anti-Dither: Press and hold this button for 3 seconds to enable

and switch between the three “Anti-Dither” modes (1-bit, 2-bit
and off). Certain graphics cards use dithering to emulate a larger
color palette, but dithering causes difficulty for maintaining lowbandwidth during real-time video compression, so these AntiDithering modes are designed to remove the dithering prior tocompression and transmission of the signal. If the source is notusing dithering, please leave this feature disabled as it may cause
a blocking effect with non-dithered content.
Note: This feature is set to “off” by default.

10 ISP: For factory use only.
11 RESET: Press this recessed button to reboot the unit (Settings will not
be reset).

method, streaming channel selection, output resolution, video
wall configuration, EDID management, Ethernet settings, andreset/firmware functions are controllable via multiple tabs in the
WebGUI interface allowing for reasonably intuitive operation.
-- Each Transmitter and Receiver is controlled by its own WebGUI
interface which may be accessed by opening a standard webbrowser on a PC and typing in the IP address of the unit you wish
to connect to. If you do not already know the IP addresses of
the units in your system, you can discover the IP addresses by
disabling the streaming link on either the Transmitter or Receiverunits in a connected system and connecting an HDMI display toeach Receiver. This is done by pressing and holding the “LINK”
button on the front of the unit for 3 seconds (The LINK light will blink
rapidly, then turn off).
-- Once the link is broken, each connected Receiver will output
a 640×480 black screen with OSD text at the bottom identifying
its own IP address (Local IP), as well as the IP address of theTransmitter (Remote IP) that shares the same broadcasting
channel with it (channel 0 by default). After obtaining the IP
address information, press and hold the “LINK” button again for 3
seconds to return the unit to normal operation (The LINK light willlight up solid yellow).
FW: 15-Nov-10 4298
Local IP: 169.254.9.180
Remote IP: 169.254.11.173
ID: FFFFFFFFFFFF-- Once you have connected to a unit’s WebGUI, you will bepresented with a screen containing multiple tabs for eachfunctionality area of the unit. To view the contents of a tab,click on the appropriate button at the top of the window. The
individual tabs and functions will be introduced in the following
sections.
-- Video over IP streaming uses a large amount of bandwidth(especially at higher resolutions) and a Gigabit Ethernet network

20

switch with jumbo frame support and IGMP snooping is required.
A professional managed switch with VLAN support is strongly
recommended. Please note that most consumer-grade routers
are not able to handle the high traffic rates generated bymulticast mode, so using a router directly as your network switch is
discouraged. It is strongly suggested to avoid mixing your regular
network traffic with VoIP streaming traffic and the VoIP traffic
should exist within a separate subnet, at the minimum.
6.6.1 System Tab
The System tab contains 4 windows that provide access to firmware
version information, a firmware update interface, utilities for rebooting
and resetting the unit, basic EDID management, Telnet commandentry, and a variety of statistics and information about the operational
state of the unit.
• Version Information
This window displays detailed information about the current firmware
version.

• Update Firmware
Provides a way to update the Transmitter’s firmware. Click “Choose
File” to select the firmware update file from the local PC (*.bin format).
After selecting an appropriate file, click the “Upload” button to begin
the update process.

21• Utilities
The Utilities window allows users to reset the unit back to the factory
defaults by clicking “Factory Default". The unit may be rebooted(without resetting settings) by pressing the “Reboot” button.
If the EDID received from the primary Receiver unit (selected via
a checkbox on the preferred Receiver in Multicast mode) has
compatibility issues with the connected HDMI source, the internal
HDMI EDID (up to 4K30 w/audio) or VGA EDID (up to WUXGA wo/
audio) can be selected. Please press “Apply” after making theselection.
Note: This EDID setting will be reset if the unit is rebooted.
Finally, individual Telnet commands may be sent to the unit by using
the “Console API Command” text entry field and pressing “Apply”.
Any responses from the unit will be displayed in the “Output” field.

22• Statistics
The Statistics window shows all available information about theoperational status of the unit, including current Host ID Name, Ethernet
information, MAC address, unicast/multicast mode, link status and
mode.

23

6.6.2 Video Wall Tab
The Video Wall tab allows user to design, edit and manipulate avideo wall system created using multiple Receiver units connected
to identical displays. The bezel and video size of the displays being
used, as well as the horizontal and vertical monitor count, is defined
here. Video stretch and rotation can also be controlled on this tab.
Receivers in the video wall group (all Receivers sharing the samechannel) can be controlled by any other unit within the same group.
The Video Wall tab is accessible on both Transmitters and Receivers,
however video wall settings may only be applied to Receiver units.
When saving changes on the Video Wall tab, remember to selectthe appropriate “Apply To:” target unit before pressing the “Apply”
button. To make changes to the unit you are currently connected
to, select “This” as the target. Otherwise, select the IP address of theReceiver (Client) you want to apply changes to from the “Apply To:”drop down.
Notes:• While it is possible to create small video walls using unicast mode, inorder to more efficiently use the available network bandwidth, it isstrongly recommended to only use multicast mode when creating
video walls.
• The Video Wall tab is optional, and will not show up in the WebGUI
tab list unless the “Enable Video Wall” checkbox on the Functions
tab is checked. It is not required to activate the Video Wall tab on
Transmitters used within video wall systems.

24• Bezel and Gap Compensation
This section of the Video Wall tab is used to define the physicaldimensions of each display being used in the video wall. Accurate
measurements are needed of the monitor’s outer frame (OW, OH)
and the video screen (VW, VH). The measurements may be madeusing any unit of measurement (inches, mm, cm, etc.) as long as ALL
measurements in the same wall are made using the exact same units
and the numbers are integers.

-- OW (Outer Width): This is the horizontal measurement of thedisplay’s outer case.
-- OH (Outer Height): This is the vertical measurement of the display’souter case.

25

-- VW (Video Width): This is the horizontal measurement of thedisplay’s video screen.
-- VH (Video Height): This is the vertical measurement of the display’s
video screen.
Note: Typically all monitors in a video wall are identical and havethe same dimensions, but it is possible to use differently sized displays
as long as the same measurement units are used to measure eachdisplay and the displays are still arranged in a normal rectangularlayout with corners meeting at the same place.
• Wall Size and Position Layout
This section of the Video Wall tab is used to define the number ofdisplays used in the video wall as well as the location of the specificdisplay within the video wall. A typical video wall consists of an equal
number of horizontal and vertical monitors (for example: 2×2 or 3×3),
however it is possible to create video walls using this system with awider variety of dimensions as long as the end result is still a rectangle(for example: 5×1 or 2×3). Both horizontal and vertical dimensions arelimited to a maximum of 8 displays.

-- Vertical Monitor Count: Define the number of displays in the video
wall, measured vertically. (Maximum is 8 displays)-- Horizontal Monitor Count: Define the number of displays in thevideo wall, measured horizontally. (Maximum is 8 displays)-- Row Position: Set the vertical location of the currently controlled
display. (Counts top to bottom, from 0 to 7)-- Column Position: Set the horizontal location of the currently
controlled display. (Counts left to right, from 0 to 7)• Preferences
This section of the Video Wall tab provides additional controls
over how the source video is displayed on the video wall as wellas providing a drop down to determine which Receiver to apply
changed settings to.

26

-- Stretch Type: Set the video stretch method.
-- Selecting “Fit In” will expand the video to exactly fit thedimensions of the video wall regardless of the source’s original
aspect ratio.
-- Selecting “Stretch Out” will zoom the video until the video wall
is filled in all 4 dimensions while maintaining the aspect ratio of
the original source.
-- Clockwise Rotate: Set the rotation of the video output in 90
degree increments.
-- Apply To: Select which unit(s) to send updated settings to when
“Apply” is pressed.
-- Selecting “All” will direct updates to the video wall settingsof all units in the current video wall group (Transmitter andReceivers).
-- Selecting “This” will direct updates to the video wall settings of
the unit whose WebGUI you are currently connected to.
-- Selecting an IP address from the “Hosts” list will direct updates
to the video wall settings of the Transmitter with that IP
address.
-- Selecting an IP address from the “Clients” list will direct
updates to the video wall settings of the Receiver with that IP
address.
-- Show OSD: Enables or disables the OSD display of the current
channel selection.
Note: When setting up a new video wall, or changing theconfiguration of an existing one, remember to update theconfiguration of each Receiver in the system.

27

6.6.3 Network Tab
The Network tab provides controls over the Transmitter’s broadcast
channel, IP configuration, and network broadcast mode. Changes
made to the network settings will require a reboot of the unit. After
clicking on “Apply” please follow the reboot instructions in the
WebGUI.
Note: If the IP address is changed then the IP address required for
WebGUI access will also change accordingly. If the new address is
assigned via “Auto IP” or “DHCP” it might be necessary to temporarily
disable the Video Link between the Receiver and Transmitter in order
to display the units’ new IP addresses on the Receiver’s HDMI output.
Press and hold the LINK button for 3 seconds to enable or disable theVideo Link.

• Channel Setup
Use the dropdown to select the broadcast channel for the Transmitter.
All Receivers on the local network that are set to the same channel
will receive video from this Transmitter. The available channel range isfrom 0 to 255.
Note: Every Transmitter within the same local network must be
assigned a different broadcast channel in order to avoid conflicts.
• IP Setup
This section allows for configuration of the IP acquisition mode and28

Ethernet settings of the unit. It also provides an easy way to find thephysical unit when installed with many other similar units.
-- IP Mode & Settings: The IP mode may be switched between “AutoIP”, “DHCP” or “Static IP”. When the unit is set to Auto IP mode it
will automatically assign itself an APIPA address from the169.254.xxx.xxx range. When the unit is set to DHCP mode it willattempt to automatically obtain an IP address from a DHCP
server. When the IP mode is set to static IP, you can manually set
the IP address, netmask and gateway address. Click the “Apply”
button to save changes made to the IP Mode or Configuration.
Note: The default network setting for this unit is “Auto IP”.
-- Find Your Device: Selecting “Show Me” will cause the unit toimmediately begin flashing the LEDs on the front of the unit tomake it easy to find. Selecting “Hide Me” returns the LEDs to theirnormal behavior. This setting is useful when troubleshooting an
installation with a large number of units in a rack.
• Casting Mode
Allows for the selection of the broadcasting mode used by theTransmitter. Click the “Apply” button to save changes made to thebroadcasting mode.
Note: Receivers must be set to the same mode as the Transmitter inorder to receive video.
-- Multicast: This mode sends a single video stream that can beviewed simultaneously by multiple receivers without increasing
bandwidth usage. This mode is ideal for video wall or matrixing
scenarios. Multicast mode requires a network switch with IGMP
snooping enabled.
Note: The 3 port network switch built into the Receiver units
supports IGMP snooping and may be used to distribute a multicast
stream.
-- Unicast: This mode uses a discrete video stream for every
connected Receiver and is ideal for simple, point-to-point,
streaming setups. This mode uses considerably more bandwidththan Unicast mode when multiple Receivers are being used,however it does not require a network switch that supports IGMP
snooping.

29

6.6.4 Functions Tab
The Functions tab provides control over the Transmitter’s video source
selection, streaming bandwidth/quality settings, as well as a wide
variety of optional features and functions, including USB and Serial
control extension. Changes made to these settings typically require a
reboot of the unit. After clicking on “Apply” please follow the reboot
instructions in the WebGUI, if necessary.

30• Video over IP
This section allows control over many critical functions of theTransmitter including: selection of the input source, enabling/
disabling the VoIP stream, enabling access to the Video Wall tab, andcontrolling the streaming bit rate and quality.

-- HDMI/VGA: Switch between the HDMI or VGA input on theTransmitter.
-- Enable Video over IP: Unchecking this checkbox will disable
the VoIP stream completely. This option should always remain
checked unless troubleshooting is being performed.
-- Enable Video Wall: Checking this box will enable the Video Walltab in the WebGUI.
Note: It is not required to enable this on the Transmitter to set up a
video wall. Only Receiver units require this to be enabled.
-- Maximum Bit Rate: Set the maximum bit rate that can be used bya single video stream. Available options are: Best Effort, 400 Mbps,
200 Mbps, 100 Mbps, 50 Mbps. Selecting “Best Effort” will use up
to the maximum available bandwidth in order to maintain a full
framerate video stream.
Note: While it is generally suggested to select “Best Effort” when
streaming 4K video sources, the amount of bandwidth required
can be very large and will limit the number of concurrent video
streams.
-- Maximum Framerate: Adjusting this slider will set the percentage
of frames from the source video to encode (2–100%). This is ideal
for reducing the bandwidth requirements of high-resolution, but
limited motion, sources such as power point presentations orinformation screens.

31Note: If the framerate is lowered too far with motion video
sources, the video will become noticeably choppy.
• USB over IP
This section provides controls for the USB over IP extension functionality,
including enabling/disabling USB support, changing the USB
operational mode, and enabling special compatibility modes.

-- Enable USB over IP: Unchecking this checkbox will completely
disable support for USB over this stream. This option should
generally remain checked, but, if USB support is not required,disabling this feature can save some bandwidth.
-- Operation Mode: Sets the USB extension mode. Available options
are Auto, Active on link (Unicast optimized), and Active per
request (Multicast optimized). Auto mode is set by default andwill automatically select the correct mode depending on the
broadcast mode of the unit.
-- Compatibility Mode: These troubleshooting options enablespecialized optimizations to solve issues when a mouse or touch
panel is not responding properly. They should normally be leftunchecked.

32• Serial over IP
This section provides controls for the Serial over IP extension
functionality, including enabling/disabling Serial support and setting
the RS-232 data configuration.

-- Enable Serial over IP: Unchecking this checkbox will completely
disable support for sending RS-232 commands over this stream.
This option should generally remain checked, but, if serial support
is not required, disabling this feature can save a very small amountof bandwidth.
-- Serial Settings: Set the desired baud rate, data bits, parity, andstop bit for the RS-232 signal to extend.
Note: The Transmitter and Receiver must have the same serial
settings.

1. INTRODUCTION
This unit is part of a 4K UHD Multi-Function Extension system that allows
you to extend HDMI or VGA signals along with KVM using the TCP/
IP protocol over regular Cat.5e/6/7 network cable. This extendersupports the transmission of Ultra High-Definition signals (up to 4K@30Hz
YUV 4:4:4 or 4K@60Hz YUV 4:2:0) with audio and USB up to 100m on asingle cable. The transmission distance can be further extended (upto 100m per segment) by using gigabit network switches, allowing theuser to cascade the system without signal loss or introducing delay.
It is also possible to have the extension system's Transmitter operate
in multicast mode, allowing you to send a single AV signal to a large
number of Receivers within the same local network. Additionally, thatsame multicast signal can be used to create large multi-display video
walls with amazing simplicity. This system is perfect for both residential
and commercial installation environments.
This system also features bi-directional IR and RS-232 pass-through,analog line level in/out, and a microphone input (on the Receiver),providing the user with a variety of audio options. The USB functionality
allows the system to act like a remote USB hub which, when combinedwith the VGA input/output feature, provides a flexible remote KVM
platform. Configuration information is provided via On Screen Display(OSD) and control is by WebGUI, Telnet, and front panel controls.

6.6 WebGUI Control• Important Notes-- All major functions of the unit, including status, streaming
method, streaming channel selection, output resolution, video
wall configuration, EDID management, Ethernet settings, andreset/firmware functions are controllable via multiple tabs in the
WebGUI interface allowing for reasonably intuitive operation.
-- Each Transmitter and Receiver is controlled by its own WebGUI
interface which may be accessed by opening a standard webbrowser on a PC and typing in the IP address of the unit you wish
to connect to. If you do not already know the IP addresses of
the units in your system, you can discover the IP addresses by
disabling the streaming link on either the Transmitter or Receiverunits in a connected system and connecting an HDMI display toeach Receiver. This is done by pressing and holding the “LINK”
button on the front of the unit for 3 seconds (The LINK light will blink
rapidly, then turn off).
-- Once the link is broken, each connected Receiver will output
a 640×480 black screen with OSD text at the bottom identifying
its own IP address (Local IP), as well as the IP address of theTransmitter (Remote IP) that shares the same broadcasting
channel with it (channel 0 by default). After obtaining the IP
address information, press and hold the “LINK” button again for 3
seconds to return the unit to normal operation (The LINK light willlight up solid yellow).
FW: 15-Nov-10 4298
Local IP: 169.254.9.180
Remote IP: 169.254.11.173
ID: FFFFFFFFFFFF-- Once you have connected to a unit’s WebGUI, you will bepresented with a screen containing multiple tabs for eachfunctionality area of the unit. To view the contents of a tab,click on the appropriate button at the top of the window. The
individual tabs and functions will be introduced in the following
sections.
-- Video over IP streaming uses a large amount of bandwidth(especially at higher resolutions) and a Gigabit Ethernet network

21

switch with jumbo frame support and IGMP snooping is required.
A professional managed switch with VLAN support is strongly
recommended. Please note that most consumer-grade routers
are not able to handle the high traffic rates generated bymulticast mode, so using a router directly as your network switch is
discouraged. It is strongly suggested to avoid mixing your regular
network traffic with VoIP streaming traffic and the VoIP traffic
should exist within a separate subnet, at the minimum.
6.6.1 System Tab
The System tab contains 4 windows that provide access to firmware
version information, a firmware update interface, utilities for rebooting
and resetting the unit, Telnet command entry, and a variety ofstatistics and information about the operational state of the unit.
• Version Information
This window displays detailed information about the current firmware
version.

• Update Firmware
Provides a way to update the Receiver’s firmware. Click “Choose File”
to select the firmware update file from the local PC (*.bin format).
After selecting an appropriate file, click the “Upload” button to begin
the update process.

22• Utilities
The Utilities window allows users to reset the unit back to the factory
defaults by clicking “Factory Default". The unit may be rebooted(without resetting settings) by pressing the “Reboot” button.
Individual Telnet commands may also be sent to the unit by using the“Console API Command” text entry field and pressing “Apply”. Any
responses from the unit will be displayed in the “Output” field.

• Statistics
The Statistics window shows all available information about theoperational status of the unit, including current Host ID Name, Ethernet
information, MAC address, unicast/multicast mode, link status and
mode.

23

6.6.2 Video Wall Tab
The Video Wall tab allows user to design, edit and manipulate avideo wall system created using multiple Receiver units connected
to identical displays. The bezel and video size of the displays being
used, as well as the horizontal and vertical monitor count, is defined
here. Video stretch and rotation can also be controlled on this tab.
Receivers in the video wall group (all Receivers sharing the samechannel) can be controlled by any other unit within the same group.
The Video Wall tab is accessible on both Transmitters and Receivers,
however video wall settings may only be applied to Receiver units.
When saving changes on the Video Wall tab, remember to selectthe appropriate “Apply To:” target unit before pressing the “Apply”
button. To make changes to the unit you are currently connected
to, select “This” as the target. Otherwise, select the IP address of theReceiver (Client) you want to apply changes to from the “Apply To:”drop down.
Notes:• While it is possible to create small video walls using unicast mode, inorder to more efficiently use the available network bandwidth, it isstrongly recommended to only use multicast mode when creating
video walls.
• The Video Wall tab is optional, and will not show up in the WebGUI
tab list unless the “Enable Video Wall” checkbox on the Functions
tab is checked.

24• Bezel and Gap Compensation
This section of the Video Wall tab is used to define the physicaldimensions of each display being used in the video wall. Accurate
measurements are needed of the monitor’s outer frame (OW, OH)
and the video screen (VW, VH). The measurements may be madeusing any unit of measurement (inches, mm, cm, etc.) as long as ALL
measurements in the same wall are made using the exact same units
and the numbers are integers.

-- OW (Outer Width): This is the horizontal measurement of thedisplay’s outer case.
-- OH (Outer Height): This is the vertical measurement of the display’souter case.

25

-- VW (Video Width): This is the horizontal measurement of thedisplay’s video screen.
-- VH (Video Height): This is the vertical measurement of the display’s
video screen.
Note: Typically all monitors in a video wall are identical and havethe same dimensions, but it is possible to use differently sized displays
as long as the same measurement units are used to measure eachdisplay and the displays are still arranged in a normal rectangularlayout with corners meeting at the same place.
• Wall Size and Position Layout
This section of the Video Wall tab is used to define the number ofdisplays used in the video wall as well as the location of the specificdisplay within the video wall. A typical video wall consists of an equal
number of horizontal and vertical monitors (for example: 2×2 or 3×3),
however it is possible to create video walls using this system with awider variety of dimensions as long as the end result is still a rectangle(for example: 5×1 or 2×3). Both horizontal and vertical dimensions arelimited to a maximum of 8 displays.

-- Vertical Monitor Count: Define the number of displays in the video
wall, measured vertically. (Maximum is 8 displays)-- Horizontal Monitor Count: Define the number of displays in thevideo wall, measured horizontally. (Maximum is 8 displays)-- Row Position: Set the vertical location of the currently controlled
display. (Counts top to bottom, from 0 to 7)-- Column Position: Set the horizontal location of the currently
controlled display. (Counts left to right, from 0 to 7)• Preferences
This section of the Video Wall tab provides additional controls
over how the source video is displayed on the video wall as wellas providing a drop down to determine which Receiver to apply
changed settings to.

26

-- Stretch Type: Set the video stretch method.
-- Selecting “Fit In” will expand the video to exactly fit thedimensions of the video wall regardless of the source’s original
aspect ratio.
-- Selecting “Stretch Out” will zoom the video until the video wall
is filled in all 4 dimensions while maintaining the aspect ratio of
the original source.
-- Clockwise Rotate: Set the rotation of the video output in 90
degree increments.
-- Apply To: Select which unit(s) to send updated settings to when
“Apply” is pressed.
-- Selecting “All” will direct updates to the video wall settingsof all units in the current video wall group (Transmitter andReceivers).
-- Selecting “This” will direct updates to the video wall settings of
the unit whose WebGUI you are currently connected to.
-- Selecting an IP address from the “Hosts” list will direct updates
to the video wall settings of the Transmitter with that IP
address.
-- Selecting an IP address from the “Clients” list will direct
updates to the video wall settings of the Receiver with that IP
address.
-- Show OSD: Enables or disables the OSD display of the current
channel selection.
Note: When setting up a new video wall, or changing theconfiguration of an existing one, remember to update theconfiguration of each Receiver in the system.

27

6.6.3 Network Tab
The Network tab provides controls over the Receiver’s broadcast
reception channel, IP configuration, and network broadcast mode.
Changes made to the network settings will require a reboot of theunit. After clicking on “Apply” please follow the reboot instructions in
the WebGUI.
Note: If the IP address is changed then the IP address required for
WebGUI access will also change accordingly. If the new address is
assigned via “Auto IP” or “DHCP” it might be necessary to temporarily
disable the Video Link between the Receiver and Transmitter in order
to display the units’ new IP addresses on the Receiver’s HDMI output.
Press and hold the LINK button for 3 seconds to enable or disable theVideo Link.

• Channel Setup
Use the dropdown to select the broadcast reception channel for
the Receiver. The Receiver will display the video stream from theTransmitter using the selected broadcast channel. The available
channel range is from 0 to 255.
• IP Setup
This section allows for configuration of the IP acquisition mode andEthernet settings of the unit. It also provides an easy way to find thephysical unit when installed with many other similar units.

28

-- IP Mode & Settings: The IP mode may be switched between “AutoIP”, “DHCP” or “Static IP”. When the unit is set to Auto IP mode it
will automatically assign itself an APIPA address from the169.254.xxx.xxx range. When the unit is set to DHCP mode it willattempt to automatically obtain an IP address from a DHCP
server. When the IP mode is set to static IP, you can manually set
the IP address, netmask and gateway address. Click the “Apply”
button to save changes made to the IP Mode or Configuration.
Note: The default network setting for this unit is “Auto IP”.
-- Find Your Device: Selecting “Show Me” will cause the unit toimmediately begin flashing the LEDs on the front of the unit tomake it easy to find. Selecting “Hide Me” returns the LEDs to theirnormal behavior. This setting is useful when troubleshooting an
installation with a large number of units in a rack.
• Casting Mode
Allows for the selection of the network broadcast mode supported by
the Receiver. Click the “Apply” button to save changes made to thebroadcast mode.
Note: Receivers must be set to the same mode as the Transmitter inorder to receive video.
-- Multicast: This mode sends a single video stream that can beviewed simultaneously by multiple receivers without increasing
bandwidth usage. This mode is ideal for video wall or matrixing
scenarios. Multicast mode requires a network switch with IGMP
snooping enabled.
Note: The 3 port network switch built into the Receiver units
supports IGMP snooping and may be used to distribute a multicast
stream.
-- Unicast: This mode uses a discrete video stream for every
connected Receiver and is ideal for simple, point-to-point,
streaming setups. This mode uses considerably more bandwidththan Unicast mode when multiple Receivers are being used,however it does not require a network switch that supports IGMP
snooping.

29

6.6.4 Functions Tab
The Functions tab provides control over the Receiver’s output
resolution, video loss settings, as well as a wide variety of optionalfeatures and functions, including USB and Serial control extension.
Changes made to these settings typically require a reboot of the unit.
After clicking on “Apply” please follow the reboot instructions in the
WebGUI, if necessary.

30• Video over IP
This section allows control over many critical functions of the Receiverincluding: enabling/disabling the VoIP stream, enabling access tothe Video Wall tab, controlling the scaler/output resolution, andcontrolling the behavior upon signal loss.

-- Enable Video over IP: Unchecking this checkbox will disable
the VoIP stream completely. This option should always remain
checked unless troubleshooting is being performed.
-- Enable Video Wall: Checking this box will enable the Video Walltab in the WebGUI.
-- Copy EDID: When multiple Receivers are connected to a single
Transmitter in multicast mode, this check box selects which of theReceivers should send its EDID to the Transmitter for use with thesource.
Note: This option is only available in multicast mode.
-- Scaler Output Mode: Use the drop down list to select the preferred
output resolution for the scaler. Selecting one of the specificresolutions will output all video at that resolution. Selecting “PassThrough” will output the source video at its original resolution.
Selecting “Native” will attempt to scale to the detected native
resolution of the display connected to the HDMI output.
-- Video Loss Options: Use the drop down to set the length of time
to wait for a lost source to return before showing the Link Lost
screen. Available options are: 3, 5, 10, 20, 30, 60 seconds, or Never
Timeout. If the “Turn off screen” checkbox is checked, the HDMI
output will be completely disabled, including sync, after thetimeout time has passed.

31

• USB over IP
This section provides controls for the USB over IP extension functionality,
including enabling/disabling USB support, changing the USB
operational mode, and enabling special compatibility modes.

-- Enable USB over IP: Unchecking this checkbox will completely
disable support for USB over this stream. This option should
generally remain checked, but, if USB support is not required,disabling this feature can save some bandwidth.
-- Operation Mode: Sets the USB extension mode. Available options
are Auto, Active on link (Unicast optimized), and Active per
request (Multicast optimized). Auto mode is set by default andwill automatically select the correct mode depending on the
broadcast mode of the unit.
-- Compatibility Mode: These troubleshooting options enablespecialized optimizations to solve issues when a mouse or touch
panel is not responding properly. They should normally be leftunchecked.

32• Serial over IP
This section provides controls for the Serial over IP extension
functionality, including enabling/disabling Serial support and setting
the RS-232 data configuration.

-- Enable Serial over IP: Unchecking this checkbox will completely
disable support for sending RS-232 commands over this stream.
This option should generally remain checked, but, if serial support
is not required, disabling this feature can save a very small amountof bandwidth.
-- Serial Settings: Set the desired baud rate, data bits, parity, andstop bit for the RS-232 signal to extend.
Note: The Transmitter and Receiver must have the same serial
settings.
