Getting Started
Installation & Configuration
The 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. We will cover both
installations.
Local Area Network (LAN) Connection
In order to connect the VGA KVM over IP to a Local Area Network (LAN), both the Sender
and Receiver unit must first 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 configured manually. Contact your network administrator if
necessary.
1.
Use the included VGA cable to connect the VGA source to the VGA In port on the
Sender unit.
2.
Connect a VGA cable from the VGA display to the VGA Out port on the Receiver unit.
3.
Connect a shielded CAT-5e (or better) cable from the Link port on the Sender unit
to the network.
4.
Connect a shielded CAT-5e (or better) cable from one of the Ethernet ports on the
Receiver unit to the network.
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.

greater than 8K.
page | 11
Getting Started
Installation & Configuration
Using a Direct Connection
By default, the 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 configure 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.
Use the included VGA cable to connect the VGA source to the VGA In port on the
Sender unit.

channel that is being used by a Sender unit.
Let’s look at an example: In the illustration below, we have one Receiver unit and
three Sender units. The numbers indicate the video channel for each Sender and
Receiver unit. Our Receiver unit is currently set to channel 2 and is receiving the
signal from the Sender unit on channel 2.

Configuring Unicast Mode
The term unicast is used to describe a configuration 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 VGA KVM over IP functions similiar to a VGA
KVM switcher.
Information
The VGA KVM over IP Sender and Receiver units shipped from the factory in
unicast mode.
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.

Switching between Sender units in Unicast mode
When multiple Sender and Receiver unit are used in unicast mode, the 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, we will switch Receiver unit R1 to receive the VGA source on Sender
unit S1. To do this, all we need to do is change the 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.
page | 26
Basic Operation
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.
Multiple Receiver units can simultaneously connect to any Sender unit within the
network including the Gefen KVM over LAN products with HDMI, DVI, or VGA video,
to create a virtual matrix of just over 65,000 Sender and Receiver units, depending
on the network bandwidth and number of ports on the network switch. Although any
combination of HDMI, DVI, and VGA Senders and Receivers can be used, HDCP
content is only supported by HDMI Sender and Receiver 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 first.
page | 27
Configuring 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 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 VGA KVM over IP functions similar to a VGA 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.

EDID Management
The VGA KVM over IP features EDID Management. Before the source can send video
(and/or audio) data, the source device (connected to each Sender unit) reads the EDID
(Extended Display Identification Data) from the displays which are connected to each
Receiver unit. The EDID contains information about what type of audio/video data can
be sent by each source.
By default, the (downstream) EDID from the display, connected to the Receiver unit, is
used. However, under certain circumstances, it may be desirable to use the internal EDID
which is stored in the Sender unit.

Download the firmware for the VGA KVM over IP from the Gefen Web site.
2.
Extract both firmware files from the .ZIP file. The .ZIP file contains two files:
►► VGAKVM-LAN-S_[version].bin
(Sender unit)
►► VGAKVM-LAN-R_[version].bin
(Receiver unit)
3.
Access the Web interface by entering the IP address of the Sender or Receiver unit.
The order in which the Sender and Receiver units are upgraded does not matter.
4.
Under the System tab, click the Update Firmware tab.
5.
Click the Browse... button and select the firmware for the unit that is being upgraded:
If upgrading the Sender unit, the filename will contain the letter “S”. If upgrading the
Receiver unit, the filename will contain the letter “R”.
In the example below, we will be updating the Sender unit. Therefore, we need the
filename that contains the letter “S”.
6.
Click the Update button.
7.
After a few moments, the Web interface will indicate that the upgrade process has
been started.
