1. INTRODUCTION
This IP to Dual HDMI Receiver solution is designed to receive a pair of
independently extended HDMI sources via a standard Gigabit Ethernet
network connection and output them via dual HDMI outputs. Both HDMI
outputs provide support for received resolutions up to 1920x1200@60Hz
along with many audio formats including 8 channel LPCM and standard
Bitstream. Receiver 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 reception of
extended 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.

6.5 WebGUI Control
• Device Discovery
Please obtain the “Device Discovery” software from your authorized dealer
and save it in a directory where you can easily nd it.
Connect the unit and your PC/Laptop to the same active network and
execute the “Device Discovery” software. Click on “Find Devices on Internet”
and a list of devices connected to the local network will show up indicating
their current IP address.
Note:DuetodualAVoIPnatureoftheunit,eachunitwillbelistedtwice,once
for each independent webpage/IP address.
By clicking on one of the listed devices you will be presented with the
network details of that particular device.
1) IP Mode: If you choose, you can alter the static IP network settings
for the device, switch the unit into DHCP mode to automatically obtain
proper network settings from a local DHCP server, or set it to “Auto IP” to
automatically select an APIPA address. Select the preferred mode from
the IP mode drop-down, then click “Save” followed by “Reboot”.
 Note:IftheunitissettoDHCPmodebutnoDHCPservercanbefound,
the unit will automatically switch into Auto IP mode.
2) WebGUI Hotkey: Once you are satised with the network settings, you
may use them to connect via Telnet or WebGUI. The network information
window provides a convenient link to launch the WebGUI directly.

7
• WebGUI Overview
Each unit contains 2 independent AVoIP receivers, and each of those
is controlled by their own WebGUI interface which may be accessed by
opening a standard web browser on a PC and typing in the IP address of
the unit you wish to connect to. If you do not already know the IP addresses
of the units in your system, you can discover the IP addresses by using the
Discovery Tool, or by disconnecting the HDMI inputs in a connected system
and connecting an HDMI display to each of the receiver’s outputs. Once the
source is lost, each connected display will output a 640×480 black screen
with OSD text at the bottom identifying its own IP address (Local IP), as
well as the IP address of the transmitter (Remote IP) that shares the same
broadcasting channel with it. After obtaining the IP address information,
reconnect the HDMI sources to return the unit to normal operation.
Once you have connected to a unit’s WebGUI, you will be presented with a
screen containing multiple tabs for each functionality area of the unit. To view
the contents of a tab, click on the appropriate button at the top of the window.
The individual tabs and functions will be introduced in the following sections.
Note: Audio/Video over IP streaming can use a large amount of bandwidth
(especially at higher resolutions) and a Gigabit Ethernet network switch
with jumbo frame support and IGMP snooping is required. A professional
managed switch with VLAN support is strongly recommended. It is strongly
suggestedtoavoidmixingyourregularnetworktracwithAVoIPstreaming
tracandtheAVoIPtracshouldexistwithinaseparatesubnet,atthe
minimum.

6.5.2 Network Tab
The Network tab provides control over this receiver’s IP conguration.
Changes made to the network settings will require a reboot of the unit. After
clicking on “Apply” please follow the reboot instructions in the WebGUI.
Note: If the IP address is changed then the IP address required for WebGUI
and Telnet access will also change accordingly. If the new address is
assigned via “Auto IP” or “DHCP” it will be necessary to obtain the newly
assignedIPaddressbycheckingDeviceDiscoveryapp,ortheunit’sOSD
display.
1) IP Setup: This section allows for conguration of the IP acquisition mode
and Ethernet settings of the unit. It also provides an easy way to nd the
physical unit when installed with many other similar units.
■ IP Mode & Settings: The IP mode may be switched between “Auto
IP”, “DHCP” or “Static IP”. When the unit is set to Auto IP mode it
will automatically assign itself an APIPA address from the 169.254.
xxx.xxx range. When the unit is set to DHCP mode it will attempt
to automatically obtain an IP address from a DHCP server. When
the IP mode is set to static IP, you can manually set the IP address,
netmask and gateway address. Click the “Apply” button to save
changes made to the IP Mode or Conguration.

12
Note: The default network setting for this unit is “Auto IP”. If the unit
issetto“DHCP”butnoDHCPservercanbefound,theIPmodewill
temporarily switch to “Auto IP” until the unit is rebooted.
■ Find Your Device: Selecting “Show Me” will cause the unit to
immediately begin ashing the LEDs on the front of the unit to make
it easy to nd. Selecting “Hide Me” returns the LEDs to their normal

depending on whether you are connected to receiver 1 or 2. Changes made
to these settings may require a reboot. Please follow the reboot instructions
in the WebGUI, if necessary.
1) Video over IP: This section allows control over enabling/disabling the
AVoIP stream, the scaler/output resolution, and the behavior upon signal
loss.

13
■ Enable Video over IP: Unchecking this checkbox will disable the
AVoIP stream completely. This option should always remain checked
unless troubleshooting is being performed.
■ Video Loss Options: Use the drop down to set the length of time to
wait for a lost source to return before showing the “Link Lost” screen.
Available options are: 3, 5, 10, 20, 30, 60 seconds, or Never Timeout.
If the “Turn o󰀨 screen” checkbox is checked, the HDMI output will
be completely disabled, including sync, after the timeout time has
passed.
■ Scaler Output Mode: Use the drop down list to select the preferred
output resolution for the scaler. Selecting one of the specic

2) USB over IP (Receiver 1 Only): This section provides control over the
USB over IP extension functionality.
■ Enable USB over IP: Unchecking this checkbox will completely
disable support for USB streaming to this unit. This option should
generally remain checked, but, if USB support is not required,
disabling this feature can save some bandwidth.
3) Serial over IP (Receiver 1 Only): This section provides controls for the
serial over IP extension functionality, including setting the RS-232 data
conguration.
■ Enable Serial over IP: Unchecking this checkbox will completely
disable support for serial streaming to this unit. This option should
generally remain checked, but, if serial support is not required,
disabling this feature can save a very small amount of bandwidth.
■ Serial Settings: Set the desired baud rate, data bits, parity, and stop
bit for the RS-232 signal to extend.
Note: The transmitter and receiver must have the same serial settings.
4) Reboot: Pressing this button will force the unit to reboot.
6.6 Telnet Control
Before attempting to use Telnet control, please ensure that both the unit and
the PC are connected to the same active networks.
Start your preferred Telnet/Console client, or use the built in client provided
by most modern computer operating systems. After starting the client,
connect by using the current IP address of the unit and port 23 (if the
communication port number used by the unit has not been changed
previously). This will connect us to the unit we wish to control and commands
may now be entered directly.
Note 1: If the IP address of the unit is changed then the IP address required
for Telnet access will also change accordingly.
Note 2: By default the unit is set to “Auto IP” mode. The current IP address
canbeobtainedbyusingtheDeviceDiscoveryapp,orbycheckingthe
