1. INTRODUCTION
This Dual HDMI to IP Transmitter solution is designed to independently
extend a pair of HDMI sources to a pair of remote HDMI outputs via a
standard Gigabit Ethernet network connection. Both HDMI inputs provide
support for resolutions up to 1920x1200@60Hz along with many audio
formats including 8 channel LPCM and standard Bitstream. Transmitter 1
also adds support for analog audio, USB 2.0, IR and serial data extension,
making it ideal for KVM or touch panel extension projects.
When using standard Ethernet cables, this unit supports the extension of
AVoIP signals up to 100 meters and the extension distance can be further
extended (up to 100m per segment) by using Gigabit Ethernet network
switches. This allows the user to cascade the system without signal loss
or introducing delay. Conguration information is provided via On Screen
Display (OSD) and control is by WebGUI and Telnet.
2. APPLICATIONS
• HDMI, USB, Audio, IR, and RS-232 extension
• Broadcasting dual sources over a standard Ethernet connection
• Touch panel point-of-sale or advertising kiosk extension
• Long distance data and video transmission via cascading
• Remote KVM control of a system
3. PACKAGE CONTENTS
• 1× Dual HDMI to IP Transmitter with USB KVM Extension
• 1× 5V/2.6A DC Power Adapter
• 1× Power Cord
• 1× IR Blaster
• 1× Operation Manual

1OUT 1 Port: Connect to HDMI source equipment such as a media
player, game console or set-top box.
Note: When paired with it’s standard dual HDMI receiver, this input will
route directly to the Out 1 port on the connected receiver.
2AUDIO IN Port: 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 Audio In port, it
will be automatically embedded into the transmitted signal, and will
completely replace any existing HDMI audio when the unit is in “Auto”
Audio over IP mode.
AUDIO OUT port: Connect to powered speakers or an amplier for
stereo analog audio output. This will output the audio from the Audio In
on the connected receiver.
Note: The Audio In audio channel from the receiver is only active
when an analog source is also connected to the Audio In port on the
transmitter.
3IR OUT Port: 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
4IN 2 Port: Connect to HDMI source equipment such as a media player,
game console or set-top box.
Note: When paired with it’s standard dual HDMI receiver, this input will
route directly to the Out 2 port on the connected receiver.
5USB 2.0 (Type-B) Port: Connect directly to a PC host to extend its USB
functionality to the USB device ports on the connected receiver.
6RS-232 Port: Connect to a PC, laptop, or serial controllable device for
the extension of RS-232 signals.
