4K Ultra HD HDMI & VGA KVM over IP S
®
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.
Getting Started
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).
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.
8. If NOT USING A PoE-compliant switch, then connect the included 5V DC power
supplies to the Sender and Receiver unit.

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.

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.
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.

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.
