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 Transmitter has no network connection the LINK LED
will not illuminate. While the Transmitter is attempting to establish
a connection with a Receiver the LINK LED will ash. When the
Transmitter has established a stable connection with a Receiver
the LINK LED will illuminate solidly.
3RS-232 IN: Connect directly to your PC/laptop to send commands
to RS-232 devices connected to the Receiver. 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
associated Receivers.
4ISP SEL: For Factory use only. By default this is set to the right (away
from the RS-232 port) and allows normal RS-232 functionality.
Setting this switch to the left enables ISP engineering mode.
5IR OUT: Connect to the provided IR Blaster to transmit IR signals sent
from the associated Receiver to devices within direct line-of-sight
of the IR Blaster.
6IR 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.
Note: When the Transmitter is in multicast mode the IR signal is sent
to all associated Receivers.
7IR WINDOW: Accepts IR signals from any standard remote control
and sends the signal to the IR Out on the associated Receiver.

5
Note: When the Transmitter is in multicast mode the IR signal is sent
to all associated Receivers.
8LOOPBACK/LINK: This button controls multiple functions:
aLoopback: Press this button momentarily to toggle the VGA
Loopback function on and off, allowing you to locally monitor non-
HDCP HDMI sources (1080p or below) for troubleshooting purposes.
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.
9MODE/Anti-DITHER: This button controls multiple functions:
aVideo Mode: Press this button momentarily 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.
bAnti-Dither: Press and hold this button for 3 seconds to enable
and switch between the three “Anti-Dither” modes (1-bit, 2-bit
and off). Certain graphics cards use dithering to emulate a larger
color palette, but dithering causes difculty for maintaining low-
bandwidth during real-time video compression, so these Anti-
Dithering modes are designed to remove the dithering prior to
compression and transmission of the signal. If the source is not
using dithering, please leave this feature disabled as it may cause
a blocking effect with non-dithered content.
Note: This feature is set to “off” by default.
10 ISP: For factory use only.
11 RESET: Press this recessed button to reboot the unit (Settings will not
be reset).
12 VGA LOOPBACK OUT: Connect to an analog VGA monitor to
locally view the connected VGA or HDMI (non-HDCP, 1080p or

6LINE IN: Connect to the stereo analog output of a device such as
a CD player or PC.
Note: When a live audio source is connected to the Line In, it will
be automatically embedded into the transmitted signal, and will
completely replace any existing HDMI audio.
7LINE OUT: Connect to powered speakers or an amplier for stereo
analog audio output. This will output the audio from the Mic In on
the connected Receiver.
Note: This function is only available in Unicast mode. The Mic In
audio channel from the Receiver is only active when an analog
source is also connected to the Line In port on the Transmitter.
