The 4K Ultra HD HDMI & VGA KVM over IP Sender and Receiver units can be connected
over a Local Area Network (LAN) or they can be directly connected to one another. Both
installations will be covered.
Local Area Network (LAN) Connection
In order to connect the 4K Ultra HD HDMI & VGA KVM over IP to a Local Area Network
(LAN), both the Sender and Receiver unit must rst be set to DHCP mode or Static IP
mode. DHCP mode will use the DHCP server to automatically assign an IP address for
each Sender and Receiver unit that is connected to the network. Static IP mode will allow
the IP address for each Sender and Receiver unit to be congured manually. Contact your
network administrator if necessary.
1. Connect an HDMI cable from the UHD/HD source to the HDMI In port on the Sender
unit.
2. Connect a VGA cable from the VGA In port on the Sender unit to the VGA source.
3. Connect a VGA cable from the VGA OUT port on the Sender unit to a local monitor.
4. Connect an HDMI cable from the UHD/HD display to the HDMI Out port on the
Receiver unit.
5. Connect a VGA cable from the VGA Out port on the Receiver unit to a display.
6. Connect a CAT-5e (or better) cable between the LAN (PoE) port on the Sender unit
and a Gigabit IP switch.
7. Connect LAN 3 (PoE) on the Receiver unit to the same network switch. Each cable
run can be up to 330 feet (100 meters).
8. If NOT USING A PoE-compliant switch, then connect the included 5V DC power
supplies to the Sender and Receiver unit.
Getting Started
Installation & Conguration
Important
If the IP switch is PoE-compliant and the Sender and Receiver are connected
through their PoE ports, external power supplies will not be required.
Additional Receivers or other devices connected to LAN 1 and LAN 2 ports of
a Receiver will however need to be powered locally.

Important
The use of a Gigabit switch with “jumbo frame” capability is required when
connecting the 4K Ultra HD HDMI & VGA KVM over IP to a network. The
switch should be set to greater than 8K.
Page 24
page | 12
Using a Direct Connection
By default, the 4K Ultra HD HDMI & VGA KVM over IP is shipped in Auto IP mode. Auto IP
mode is used for directly connecting Sender and Receiver units to one another. In Auto IP
mode each Sender and Receiver unit assigns itself a unique IP address within the range of
169.254.x.x. To congure the units to work over a LAN, we must access the
Web interface of the Sender and Receiver unit on a computer. Then, we can change
the network settings.
1. Connect an HDMI cable to connect the UHD/HD source to the HDMI In port on the
Sender unit.
2. Connect an HDMI cable from the UHD/HD display to the HDMI Out port on the Receiver unit.
3. Connect a shielded CAT-5e (or better) cable from the LAN (PoE) port on the Sender
unit to the LAN 3 (PoE) port on the Receiver unit. While any of the three ports on the
Receiver can be used, we recommend using LAN 3 (PoE) for the sake of consistency.
4. Connect another shielded CAT-5e (or better) cable from one of the LAN ports on the
Receiver unit to a PC.
5. Connect the included 5V DC locking power supplies to both the Sender unit and
Receiver unit. Do not overtighten the locking connectors. Connect the included AC
power cords from the power supplies to available electrical outlets.
6. Obtain the IP address of both the Sender and Receiver unit by disconnecting the
HDMI cable from the Sender unit (or from the source device). Information, similar to
the illustration on the next page, will be displayed.

Configuring Unicast Mode
The term unicast is used to describe a conguration where information is sent from one
point to another point. It is possible to have multiple Sender and Receiver units connected
in a system. However, in unicast mode a Sender unit can communicate with only one
Receiver unit at a time. In unicast mode, the 4K Ultra HD HDMI & VGA KVM over IP
functions similar to a KVM switcher.
The illustration, below, shows 3 Sender units (S1, S2, and S3) and 2 Receiver units
(R1 and R2) on a network, operating in unicast mode. The video channels are notated
in blue.
Figure 2.1 - Unicast mode: A Sender unit can communicate with only one Receiver unit at
a time.

Switching between Sender units in Unicast mode
When multiple Sender and Receiver unit are used in unicast mode, the 4K Ultra HD
HDMI & VGA KVM over IP behaves as a switcher. In unicast mode, a Sender unit can
communicate with only one Receiver unit at a time.
In the example below, Receiver unit R1 will be switched to receive the source connected to
Sender unit S1. To do this, simply change the video channel.

Now, observe the result when both Sender S1 and S2 are set to channel 5:
Figure 2.4 - Unicast mode violation: Two Sender units (S1 and S2) using the same
video channel.
In this example, Receiver R1 will continue to receive audio/video data from Sender
S1, even though Sender S2 is set to the same channel. The reason for this is
because Receiver R1 and Sender S1 were already set to the same channel and
communicating (as depicted in Figure 2.3). However, this scenario violates the
unicast mode rule: A Sender unit can communicate with only one Receiver unit
at a time.

Unicast & Multicast Modes
When using unicast mode, each of the Sender units must be assigned a unique
channel and should never be changed. Use the Receiver unit to switch (channels)
between Sender units.
Information
In unicast mode, if an additional Sender unit is introduced into a system with
the same channel as another Sender unit, then the Receiver unit will continue
to receive audio/video data from the Sender unit which was connected rst.

Configuring Multicast Mode
The term multicast is used to describe a conguration where information is sent from one
or more points to a set of other points. For example, a single Sender unit can transmit data
to multiple Receiver units. In addition, if multiple Sender units are used, each Sender unit
can transmit data to any Receiver that is not already receiving data from another Sender
unit. In multicast mode, the 4K Ultra HD HDMI & VGA KVM over IP functions similar to a
HD KVM matrix.
The illustration, below, shows 3 Sender units (S1, S2, and S3) and 2 Receiver units
(R1 and R2) on a network, operating in multicast mode. The video channels are shown
in blue.

Active on link mode
Under Active on link mode, a maximum of four USB devices can be used within a system.
In the diagram, on the previous page, the system is already using the maximum number of
USB devices (2 USB devices per Receiver). If we had two more Receiver units (making
a total of four Receiver units), we would only be able to connect one USB device to each
Receiver unit. To switch to Active on link mode, follow the instruction below.
1. Access the Web interface for the Sender unit.
2. Login as “Administrator”.
3. Click the Functions tab.
4. Locate the USB over IP group and make sure the Enable USB over IP box is
checked. This is the default setting.
5. Click the Active on link radio button within the USB over IP group.
6. Click the Apply button within the USB over IP group.
7. The following message will be displayed, at the top of the page, indicating that the
new Serial over IP options have been applied.
8. Click the Reboot button at the bottom of the page. If the Reboot button is not clicked,
the following message will be displayed, indicating that the unit must be rebooted.
9. Repeat steps 2 - 8 for the Receiver unit.

Audio works in both unicast and multicast modes. The only difference between the two
modes is that the Line In port is automatically disabled, on all Receiver units, in multicast
mode. To illustrate how audio works with the 4K Ultra HD HDMI & VGA KVM over IP, we
will set up a microphone and some speakers.
1. Connect a 3.5mm mini-stereo cable from the Line In port on the Sender unit to the
Line Out port on the computer.
2. Connect another 3.5mm mini-stereo cable to from the Line Out port on the Sender
unit to the Line In port on the computer.
3. Connect a 3.5mm mini-stereo cable from the Line In port on the Receiver to the
output of a microphone pre-amp or another “Line Level” audio source.

Information
When a cable is connected to the Line In port on the Sender unit, it takes
priority over and replaces the audio from the HDMI input. The audio will be
heard on the HDMI Out, Line Out, and Opt Out ports on the Receiver unit.
Important
The Line In port requires “Line Level” audio output and certain microphones
will require a pre-amp connected inline to be compatible. Alternately, you can
use a USB mic connected to one of the USB 2.0 ports on the Receiver.

Audio Sources and De-Embedding
The following outlines the audio de-embedding functionality of this product.
• If a 3.5mm mini-stereo cable is connected to the Line In port on the Sender unit,
then the HDMI audio will be disabled on the Receiver unit. The Line Out port, on the
Receiver unit, will output audio from the source connected to the Line In port on the
Sender unit.
• When a source is connected to the Line In port on the Sender unit, the audio will be
heard on the HDMI Out, Line Out, and Opt Out ports.
• The Line In port on the Receiver unit will only pass audio to the Line Out port on the
Sender unit when in unicast mode.
• The Opt Out port will de-embed both 2-channel PCM and Bitstream (up to 5.1
channel) audio from the HDMI In port. High-resolution (lossless) audio will not be
outputted.
• HDMI source audio, from the Sender unit, will pass to the HDMI Out and Opt Out
ports on the Receiver unit. HDMI audio will not be converted or down-mixed on the
Line Out port on the Receiver unit.

Creating Video Walls
The web interface 4K Ultra HD HDMI & VGA KVM over IP allows the creation of video walls
up to 16 horizontal and 16 vertical displays. Video walls may contain any number or rows
and columns and any combination of these can be enabled, as necesary.
Wall Size and Layout
1. Access the Web interface for the Receiver unit.
2. Login as “Administrator” or “User”.
3. Click the Video Wall tab.
4. Under the Wall Size and Position Layout window group, click the drop-down lists for
the Vertical Monitor Count and Horizontal Monitor Count and select the number of
rows and columns of displays, respectively.
Page 62
page | 50
Basic Operation
5. Select the row and column positions using the Row Position and Column Position
drop-down lists.
6. Click the drop-down list, next to the Apply button, to select the desired host or client to
which these settings will be applied.
If the All option is selected, then all parameters will be transferred to all Receiver
units. For monitor count and bezel compensation in a video wall array of matching
displays, this is ne, but the row and position will also be copied. There is an option for
“This” unit that will apply to the current unit being interfaced with. The “This” option can
be used to precisely set the proper position of each unit but would require the user to
access the web interface of each unit to set. Alternatively, the drop-down will provide
a list of all connected host (Sender units) and clients (Receiver units). This process
allows the conguration of an entire video wall from a single unit.
Creating Video Walls
Basic Operation

Bezel and Gap Compensation
Display devices have a region where video data is not displayed. This area is called the
bezel. Bezel compensation takes this area into account when a single video source is
mapped across multiple displays. It is recommended, when a video wall is set up for the
rst time, that bezel compensation values be set to zero. Bezel compensation can be
adjusted at any time.
The illustration on the left shows a 2x2 video wall without bezel compensation. Note how
the circle is stretched, slightly, horizontally. On the right, bezel compensation is used to
correct the “distorted” image.
1. Access the Web interface for the Sender unit.
2. Login as “Administrator” or “User”.
3. Click the Video Wall tab.
4. Adjust the values under the Bezel and Gap Compensation window group. Refer
to the diagram, to the right of each eld, to see the effect of each value. All entered
values are applied to the physical displays in 0.1 millimeter increments.
