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 transmitters, 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.

and link mode.

11
6.5.2 Network Tab
The Network tab provides control over this transmitter’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.
 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.

behavior. This setting is useful when troubleshooting an installation
with a large number of units in a rack.
2) Reboot: Pressing this button will force the unit to reboot.
6.5.3 Functions Tab
The Functions tab provides control over the transmitter’s AV source
management, streaming bandwidth/quality settings, as well as dening
how audio and serial signals are handled (transmitter 1 only). The available
controls are di󰀨erent depending on whether you are connected to transmitter
1 or 2. Changes made to these settings may require a reboot. Please follow
the reboot instructions in the WebGUI, if necessary.

13
1) Video over IP: This section allows control over the streaming bit rate
and transmission quality.
Maximum Bit Rate: Set the maximum bit rate that can be used by
the output video stream. Available options are: Unlimited, 400 Mbps,
200 Mbps, 100 Mbps, 50 Mbps. Selecting “Unlimited” will use up to
the maximum available bandwidth in order to maintain a full framerate
video stream.
Maximum Frame Rate: Adjusting this slider will set the percentage
of frames from the source video to encode (2–100%). This is ideal for
reducing the bandwidth requirements of high-resolution, but limited
motion, sources such as slide presentations or information screens.
Note: If the framerate is lowered too far with motion video sources, the
video will become noticeably choppy.
2) Audio over IP (Transmitter 1 Only): The audio source to embed in
the transmitter’s outbound AVoIP stream is selected here. Selecting
“HDMI” will always embed HDMI 1’s audio source, selecting “Line In” will
always embed the Line In audio source, selecting Auto will embed audio
according to the default routing behavior (see section 8.3.3).
3) Serial over IP (Transmitter 1 Only): This section provides controls for
the serial over IP extension functionality, including setting the RS-232
data conguration.
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.

14
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
OSD info screen when there is no live video connection. The default
communication port is 23.
