TX List
The A20-Nexus TX List is an inventory of all paired A20-Mini transmitters and to which RX channels they are NexLinked.
To establish NexLink communication between an A20-Mini transmitter and a Nexus receiver channel, the transmitter must first be
added to the TX List in a process called ‘pairing’ and then be assigned to a receiver channel.
The TX List displays the following columns:
●
Name: The name of the transmitter.
●
Chan: The receiver channel number to which the transmitter is NexLinked.
●
Serial: Displays the last eight digits of the A20 transmitter’s serial number.
●
NexLink: Displays NexLink status.
○
---: Waiting to hear from the A20 transmitter
○
Connecting: Establishing NexLink communication.
○
Connected: NexLink communication established
Tip:
The TX List icon in the Main Menu is yellow if not all transmitters are connected and green when all
transmitters are successfully connected or when no transmitters have been paired.
Rotate the HP knob to scroll through the TX list. Select a transmitter by highlighting its row, then press the HP knob to jump directly
to its receiver channel’s 1RX View.
Pairing an A20 Transmitter
1.
Enter the TX List by tapping the TX List icon in the Main Menu.
2.
Connect the A20-Mini transmitter’s USB-C port directly to the A20-Nexus USB-A port or via a USB hub. It is not necessary
for the A20-Mini to be powered on or for it to have a battery installed.
3.
Wait for several seconds while the A20-Mini pairs to the Nexus. The A20-Mini will appear at the top of the list once paired.
4.
Disconnect the USB cable connecting the A20 transmitter to the Nexus.
Pairing automatically assigns the transmitter to the next available receiver channel number.
Once transmitters are paired, they remain permanently in the TX List until unpaired.
Activating NexLink between a Paired Transmitter and Nexus Receiver Channel
Assigning a paired transmitter to a receiver channel establishes NexLink communication between the transmitter and receiver
channel.
1.
Enter the TX List.
2.
Rotate the HP knob to select a transmitter, then tap the ‘Chan’ box.
3.
Rotate the HP knob to choose a channel number, then press the HP knob to store.
Alternatively
1.
Access a receiver channel’s 1RX View
2.
Tap the NexLink Icon to display the ‘NexLinked Transmitter’ List from which you can select an A20-Mini transmitter to
NexLink.
Deactivating NexLink between a Paired Transmitter and Nexus Receiver Channels
If some paired transmitters are not needed for a particular production, it is recommended to deactivate their NexLink communication.
To do this, set their receiver channel numbers (‘Chan’) to ‘-’.
