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

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.

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

lower) source.

ports on the connected Receiver.

3LAN (PoE): Connect via a Gigabit Ethernet switch to compatible

Receiver(s) to transmit data, and to a PC/laptop to control the unit

via WebGUI.

Note: This unit can be powered directly by the connected Gigabit

Ethernet switch if it provides PoE (802.3af).

4VGA IN: Connect to VGA source equipment such as a PC or

laptop.

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.
