1. INTRODUCTION
This unit is an HDMI over IP Transmitter that allows you to extend
HDMI signals using the TCP/IP protocol over regular Cat.5e network
cable. This extender supports the transmission of High-Denition
signals (up to 1080p@60Hz) with audio up to 100m on a single cable.
The transmission distance can be further extended (up to 100m per
segment) by using Gigabit Ethernet network switches, allowing the
user to cascade the system without signal loss or introducing delay.
This Transmitter also features bi-directional IR and RS-232 pass-through.
It is also possible to for this Transmitter to operate in multicast mode,
allowing you to send a single AV signal to a large number of Receivers
within the same local network with no additional bandwidth cost.
Additionally, that same multicast signal can be used to create large
multi-display video walls with amazing simplicity.
This Video over IP system is perfect for both residential and commercial
installation environments. Conguration information is provided via the
On-Screen Display (OSD) on connected (but unlinked) Receivers and
control is via WebGUI, Telnet, or the AV over IP Master Controller.
2. APPLICATIONS

6.5 WebGUI Control
• Accessing the WebGUI
All major functions of the unit, including status, streaming method,
streaming channel selection, output resolution, video wall
conguration, EDID management, Ethernet settings, and reset/
rmware functions are controllable via multiple tabs in the WebGUI
interface allowing for reasonably intuitive operation.
Each Transmitter and Receiver in the system is controlled by its own
WebGUI interface which may be accessed by opening a standard
web browser 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 the Receiver units in a connected system and
connecting an HDMI display to each Receiver. This is done by pressing
and holding the “LINK” button on the front of a Receiver 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 the Transmitter (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 will light 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 be presented
with a screen containing multiple tabs for each functionality 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.
Note: Video over IP streaming uses a large amount of bandwidth
and a Gigabit Ethernet network switch with jumbo frame support and
IGMP snooping is required. A managed switch with VLAN support is
strongly recommended.

6.5.2 Video Wall Tab
The Video Wall tab allows the user to design, edit and manipulate a
video 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 dened
here. Video stretch and rotation can also be controlled on this tab.
Receivers in the video wall group (all Receivers sharing the same
channel) 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 select
the appropriate “Apply To:” target unit before pressing the “Apply”
button. Select the IP address of the Receiver you want to apply
changes to from the “Apply To:” drop down.
Note: While it is possible to create small video walls using unicast
mode,doingsowastesbandwidth.Inordertomoreefcientlyusethe
available network bandwidth, it is strongly recommended to only use
multicast mode when creating video walls.

11
1) Bezel and Gap Compensation: This section of the Video Wall tab
is used to dene the physical dimensions 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 made using 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.
Note: Typically all monitors in a video wall are identical and have
the same dimensions, but it is also possible to make a 2×2 wall
using differently sized displays as long as the same measurement
units are used to measure each display and the displays are still
arranged in a normal rectangular layout with all 4 corners meeting
at the same place.
■ OW (Outer Width): This is the horizontal measurement of the
display’s outer case (screen plus bezel).
■ OH (Outer Height): This is the vertical measurement of the
display’s outer case (screen plus bezel).
■ VW (Video Width): This is the horizontal measurement of the
display’s video screen.
■ VH (Video Height): This is the vertical measurement of the
display’s video screen.
■ Apply To: Select which unit(s) to send updated settings to when
“Apply” is pressed.
– Selecting “All” will send video wall bezel setting changes to
all units in the current video wall group.
– Selecting an IP address from the “Clients” list will send any
bezel setting changes to the Receiver with that IP address.

12
2) Wall Size and Position Layout: This section of the Video Wall tab
is used to dene the number of displays used in the video wall as
well as the location of the specic display 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 a wider 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 are limited to a
maximum of 16 displays.
■ Vertical Monitor Count: Dene the number of displays in the
video wall, measured vertically. (Maximum is 16 displays)
■ Horizontal Monitor Count: Dene the number of displays in the
video wall, measured horizontally. (Maximum is 16 displays)
■ Row Position: Set the vertical location of the currently controlled
display. (Counts top to bottom, from 0 to 15)
■ Column Position: Set the horizontal location of the currently
controlled display. (Counts left to right, from 0 to 15)

13
3) Preferences: This section of the Video Wall tab provides additional
controls over how the source video is displayed on the video wall
as well as providing a drop down to determine which Receiver to
apply changed settings to.
Note: When setting up a new video wall, or changing the
congurationofanexistingone,remembertoupdatethe
congurationofeachReceiverinthesystem.
■ Stretch Type: Set the video stretch method.
– Selecting “Fit In” will expand the video to exactly t the
dimensions of the video wall regardless of the source’s
original aspect ratio.
– Selecting “Stretch Out” will zoom the video until the video
wall is lled in all 4 dimensions while maintaining the aspect
ratio of the original source.
■ Clockwise Rotate: Set the rotation of the video output in 0, 180
and 270 degree increments.
■ Apply To: Select which unit(s) to send updated settings to when
“Apply” is pressed.
– Selecting an IP address from the “Clients” list will send video
wall setting changes to the Receiver with that IP address.
■Show OSD: Enables or disables the OSD display of the current
channel selection.

14
6.5.3 Network Tab
The Network tab provides controls over the Transmitter’s broadcast
channel, IP conguration, 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 the
Video Link.

15
1) 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 is from 0 to 255.
Note: Every Transmitter within the same local network must be
assignedadifferentbroadcastchannelinordertoavoidconicts.
2) IP Setup: This section allows for conguration of the IP acquisition
mode and Ethernet settings of the unit. It also provides an easy
way to nd the physical unit when installed with many other similar
units.
■IP Mode & Settings: The IP mode may be switched between
“Auto IP”, “DHCP” or “Static IP”. When the unit is set to Auto IP
mode it will automatically assign itself an APIPA address from
the 169.254.xxx.xxx range. When the unit is set to DHCP mode it
will attempt 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
Conguration.
Note: The default network setting for this unit is “Auto IP”.
■ Find Your Device: Selecting “Show Me” will cause the unit to
immediately begin ashing the LEDs on the front of the unit to
make it easy to nd. Selecting “Hide Me” returns the LEDs to
their normal behavior. This setting is useful when troubleshooting
an installation with a large number of units in a rack.
