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 extender
supports the transmission of Ultra High-Denition signals (up to 4K@30Hz
YUV 4:4:4 or 4K@60Hz YUV 4:2:0) with audio and USB up to 100m on a
single cable. The transmission distance can be further extended (up
to 100m per segment) by using gigabit network switches, allowing the
user 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, that
same 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 combined
with the VGA input/output feature, provides a exible remote KVM
platform. Conguration 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

1POWER LED: This LED will ash while the unit is powering on and will
illuminate solidly once it is ready to be used.
2LINK LED: If the Receiver has no network connection the LINK LED
will not illuminate. While the Receiver is attempting to establish
a connection with a Transmitter the LINK LED will ash. When the
Receiver has established a stable connection with a Transmitter
the LINK LED will illuminate solidly.
3USB 2.0: These 2 USB 2.0 slots provide connections for USB devices
requiring higher transfer speeds such as thumb drives.
Note: Isochronous (steady streaming) data devices such as USB
cameras and external hard drives are not supported.
4USB 1.1: These 2 USB 1.1 slots provide connections for slower USB
devices such as keyboards, mice, etc.
Note: Isochronous (steady streaming) data devices such as USB
cameras and external hard drives are not supported.
5RESET: Press this recessed button to reboot the unit (Settings will not
be reset).
6SWITCH/MODE: This button controls multiple functions:
aSwitch Input: Press this button momentarily to switch between the
two available video inputs (HDMI and VGA).
Note: Due to the nature of streaming video and HDCP, the switch
may take up to 6–10 seconds to complete.
bVideo Mode: Press and hold this button for 3 seconds 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.

7CH+/LINK: This button controls multiple functions:
aChannel +: Press this button momentarily to increase the streaming
channel to the next available channel on the local network.
Note: If no other channels are detected, the channel number will
not change.
bVideo Link: Press and hold the button for 3 seconds to enable or
disable the Video Link. When the link is disabled and the Receiver
is connected to a display it will show the system’s current IP and
rmware information.
cReset to Factory Defaults: Press and hold this button when
powering the unit on until both the POWER and LINK lights are
blinking. 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 the
streaming mode to multicast). A new IP address will be assigned
automatically within the 169.254.xxx.xxx address range.
8 CH−/USB: This button controls multiple functions:
a Channel −: Press this button momentarily to decrease the
streaming channel to the previous available channel on the local
network.
Note: If no other channels are detected, the channel number will
not change.
bUSB: Press and hold the button for 3 seconds to enable/disable
the USB connection between the Transmitter and the Receiver.
(Multicast Mode ONLY)
Note: In Multicast mode is it only possible to provide USB support
to a single Receiver at a time. Enabling USB on one Receiver will
disable it on all other Multicast Receivers on the same channel.
9IR WINDOW: Accepts IR signals from any standard remote control
and sends the signal to the IR Out on the associated Transmitter.
10 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.
11 IR OUT: Connect to the provided IR Blaster to transmit IR signals
from the associated Transmitter to devices within direct line-of-sight
of the IR Blaster.

12 ISP SEL: For Factory use only. By default this is set to the left (towards
the RS-232 port) and allows normal RS-232 functionality. Setting this
switch to the right enables ISP engineering mode.
13 RS-232: Connect directly to an RS-232 controllable device to
receive commands from the device connected to the Transmitter.
The baud rate is congurable, 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 Transmitter
and commands sent from the Transmitter side will be sent to all
connected Receivers.
