1. Transmitter status LED: shows the current status of the transmitter
2. Headphone connector: plug in headphone to check all audio input (audio over Dante™ and audio from the auxiliary audio inputs). Select the channel and adjust the volume using the web server.
3. Monitoring Infrared LEDs: LED lights transmitting the same IR signal as the radiator, this allows you to monitor the transmitted audio using a Lingua IR receiver.
4. Reset button: different reset options are available see "Reset the Lingua IR transmitter" on page 1 for more information.
5. Mains connection: with fuse and spare fuse
6. On/Off switch
7. Dante™ signal input: interface to connect the transmitter to a conference system. The primary connector is marked by "1" and the secondary by "2"(use for redundancy).
8. Auxiliary audio inputs: connect with audio installation (left) or emergency system (right).
9. Emergency/Override switch connector: Close the left switch to override the audio on all output channels, use right switch to broadcast emergency signal on all output channels. If both switches are closed the emergency signal has priority.

Reset the Lingua IR transmitter

There is a reset button on the transmitter that allows you to reset specific settings depending on the reset procedure you perform:

reset network settings:

When the status LED is green (after power-up), you can reset the network settings back to 192.168.0.140 with subnet mask 255.255.255.0. Press and hold the reset button until the status LED changes to red (approximately 10 seconds). After you release the reset button, the transmitter will reboot with the default network settings.

Factory reset

When you perform a factory reset you reset network settings and all configurations. Press and hold the reset button before switching on the power of the transmitter. Hold the reset button until the status LED turns blue. Release the reset button to reboot the transmitter in fallback mode.

In fallback mode, the web server will have reduced functionalities. You are only able to upload an update file. After reboot, the web server will have all functionalities again. Now, upload the update file again to complete the update process of the firmware. After the final reboot, you can create new configurations.
