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.

5
7IR WINDOW: Accepts IR signals from any standard remote control and
sends the signal to the IR Out on the associated Receiver.
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 o󰀨, 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 o󰀨).
Certain graphics cards use dithering to emulate a larger color palette,
but dithering causes di󰀩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 e󰀨ect with non-dithered content.

For factory use only.
11 RESET:
Press this recessed button to reboot the unit (Settings will not be
reset).

5HDMI IN: Connect to HDMI source equipment such as a media player,
game console or set-top box.
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.
