1. INTRODUCTION
The inherent routing exibility of Audio over IP (AoIP) provides great
advantages over traditional audio cabling solutions while using highly
cost eective Cat.5e cable. This greatly reduces the cost of wiring large
systems and improves control convenience. This unit takes full advantage
of the core benets provided by AoIP and adds support for a selection
of dierent audio source formats, including both analogue (line in and
mic in) and digital (optical S/PDIF). This product allows you to easily
extend your audio sources to compatible audio playback devices located
anywhere on the local network.
Standard control is provided by front panel controls, WebGUI, and Telnet.
Advanced control and system integration is possible using the optional IP
Master Controller.

Device Discovery
Please obtain the“Device Discovery” software from your authorised 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: This unit defaults to Auto IP mode. The current IP address can be veried
using the Device Discovery software.
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, or switch the unit into DHCP mode to automatically obtain
proper network settings from a local DHCP server. To switch to DHCP
mode, please select DHCP from the IP mode drop-down, then click
“Save” followed by “Reboot”.

6
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.
WebGUI Overview
All major functions of the unit, including status, streaming method,
streaming channel selection, input selection, gain/mute control, Ethernet
settings, and reset/rmware functions are controllable via multiple tabs in
the WebGUI interface allowing for reasonably intuitive operation.
Each transmitter and receiver in the system is controlled by its 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 Device
Discovery software.
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: A Gigabit Ethernet network switch with IGMP snooping is required
when using multicast mode. A managed switch with VLAN support is strongly
recommended.

7
6.4.1 System Tab
The System tab contains four windows that provide access to rmware
version information, a rmware update interface, utilities for rebooting
and resetting the unit, Telnet command entry, and a variety of statistics
and information about the operational state of the unit.
1) Version Information: This window displays detailed information
about the current rmware version.
2) Update Firmware: Provides a way to update the transmitter’s
rmware. Click“Choose File”to select the rmware update le from
the local PC (*.bin format). After selecting an appropriate le, click the
“Upload” button to begin the update process.

8
3) Utilities: The Utilities window allows users to reset the unit back to
the factory defaults by clicking “Factory Default”. The unit may be
rebooted (without resetting settings) by pressing the“Reboot”button.
Finally, individual Telnet commands may be sent to the unit by using
the “Console API Command”text entry eld and pressing “Apply”. Any
responses from the unit will be displayed in the“Output” eld.

9
4) Statistics: The Statistics window shows all available information about
the operational status of the unit, including current Host ID Name,
Ethernet information, MAC address, unicast/multicast mode, link
status and mode.

10
6.4.2 Network Tab
The Network tab provides controls over the transmitter’s broadcast
channel, IP conguration, and network broadcast mode. 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
access will also change accordingly. If the new address is assigned via “Auto
IP” or “DHCP” it can be veried using the Device Discovery software.
1) Channel Setup: Use the dropdown to select the broadcast channel
for the transmitter. All receivers on the local network that are set to the

11
same channel will receive audio from this transmitter. The available
channel range is from 0 to 255.
Note: Every transmitter within the same local network must be assigned a
dierent broadcast channel in order to avoid conicts.
2) 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”.
Find Your Device: Selecting “Show Me”will cause the unit to
immediately begin ashing the PWR and LINK LEDs on the front
of the unit to make it easy to nd. Selecting “Hide Me” returns
the LEDs to their normal behavior. This setting is useful when
troubleshooting an installation with a large number of units in a
rack.
3) Casting Mode: Allows for the selection of the broadcasting mode
used by the transmitter. Click the“Apply” button to save changes
made to the broadcasting mode.
Note: Receivers must be set to the same mode as the linked transmitter in
order to receive audio.
Multicast: This mode sends a single audio stream that can be
played simultaneously by multiple receivers without increasing
bandwidth usage. This mode is ideal for matrixing scenarios.
 Note: Multicast mode requires a network switch with IGMP snooping
enabled.
Unicast: This mode uses a discrete audio stream for every
connected receiver and is ideal for simple, point-to-point, streaming
setups. This mode uses considerably more bandwidth than Unicast
mode when multiple receivers are being used, however it does not
require a network switch that supports IGMP snooping.

12
6.4.3 Functions Tab
The Functions tab provides control over the transmitter’s audio source
selection, audio mute/unmute, mic gain, front panel locks and serial
control extension conguration. Changes made to these settings typically
require a reboot of the unit. After clicking on “Apply” please follow the
reboot instructions in the WebGUI, if necessary.
1) Audio over IP: This section allows control over selection of the input
source, enabling/disabling the audio mute, changing the microphone
gain, and front panel locks.

13
Audio Select: Select between the optical, line or mic inputs on the
transmitter.
Audio Mute: Enable or disable muting the audio output.
Mic Input Gain: Increase or decrease the audio gain of the
microphone input by dragging the slider.
 Note: This is only controllable when Mic In is the selected source.
Front Panel Lock for Device Button and Knob: Enable or disable
either of these lock types for the front panel. When the locks are
enabled, the user can only change settings using the WebGUI or
Telnet commands.
2) Serial over IP: 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.
6.5 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: This unit defaults to Auto IP mode. The current IP address can be
veried using the Device Discovery software. The default communication port
is 23.
