System information

F
firmware
The embedded software in each component. Firmware can be updated to incorporate new features and hardware enhancements.
flash
An identification feature that flashes the LED and backlit buttons on the front panel of a device in a rack.
frequency coordination
A calculation which uses RF scan data, the constraints of the equipment in inventory, known frequencies to avoid, and information about the RF environ-
ment to generate a Compatible Frequency List (CFL).
Frequency Diversity
The transmission of audio from a single source over two independent frequencies. Combines signal from both frequencies to provide optimized audio on
a single audio channel.
Frequency List
Displays the compatible frequencies for all zones after you deploy frequencies to the inventory.
frequency plot
A graphical representation of the data obtained by a scan of the RF spectrum.
G
group and channel
A predefined set of hardware-specific frequencies that are coordinated to work with one another.
I
interference alert
A message displayed when the AXT400 receiver senses low-level interference. Interference at this level may not be audible or may only cause a slight
disruption to the audio signal. If Interference Avoidance is set to Auto mode, a frequency change will not occur unless the strength of the interference
increases to trigger an Interference Detected message. In Wireless Workbench, the Interference Detected window opens.
interference detected
A message displayed when the AXT400 receiver senses interference powerful enough to degrade the audio signal. If Interference Avoidance mode is
set to Auto, the channel can automatically switch to a clear frequency deployed by a Spectrum Manager (AXT600) when detection occurs. In Wireless
Workbench, the Interference Detected window opens.
intermodulation products
Unwanted RF signals created within components when two RF carriers are in close physical proximity. Intermodulation products can cause interference
and increase the amount of occupied bandwidth.
Inventory list
On the Inventory tab of Wireless Workbench, the Inventory list displays the online and offline equipment you have added to the show. It provides a way
of reviewing and sorting your equipment.
IP address
A number assigned to a device that identifies its location on the network. The IP address ensures that data on the network is sent to the correct device.
IR sync
Uses an infrared signal to automatically tune transmitter frequency and control settings to those of a selected receiver.
L
linking
Linking Axient transmitters and receivers enables synchronized frequency changes and remote control. Linking automatically occurs during the IR sync
process and remains in place until the components are unlinked by command.
M
merging
A feature of Wireless Workbench that asks you to resolve any conflicts of parameter values between offline and online devices.
N
networking
Networking components over Ethernet allows the devices to communicate and perform advanced features.
O
offline device
A device that is not currently online, but that is included in the Inventory list in Wireless Workbench.
