LX400 STL - Quick Install Guide

Please make sure to first read the safety information in order to avoid hazards.

The scope of this document is to give a thorough introduction on the LX400 STL. At the end of this guide the user will be able to run a basic setup and have an audio stream playing.

LX400 STL runs the STL Flexa application. Refer to LX400 STL User Manual (https://help.barix.com/lx400-stl/lx400-stl-manual) for a complete explanation on the software functionalities.

Before you start using the LX400 STL

A few things you need to know before you can effectively use the LX400 STL broadcast encoder decoder.

What is FLEXA

The LX400 STL runs a firmware that is called FLEXA. STL is an application running on the FLEXA firmware. That should not concern you. Most important for you are the menus SETTINGS, CLIENT HOME and LOCAL CONFIG.

No need to press any of the buttons on the HOME screen. Key there is that it shows “Application Status running”.

When you enable the FLEXA AGENT, then the unit will call into the Internet (if it can reach it) and automatically get firmware updates. It also enable Portal Config via SUPICONF (see below).

To run the unit stand-alone with the local GUI for configurations, disable the FLEXA AGENT.

Important: If you have the FLEXA AGENT enabled, and then try to change the configuration you will get the following warning.

If you click "Proceed", then the FLEXA agent will be disabled, putting you back in stand-alone mode.

What is SUPICONF?

Your LX400 STL is SUPICONF ready. SUPICONF is a future portal solution by BARIX that allows you to configure the unit via a Web Portal instead of locally via Web GUI.

The Portal is available in Beta version and you can try it.

A key shortcomings of the Beta Version is that synchronization between the Portal and the device only happens once an hour. This will be improved to a much shorter reaction time in the final release.

Interested in SUPICONF?

If you are interested in SUPICONF and want to get an account, please contact the vendor who sold you the unit. They can enable your free SUPICONF account.

Package Content

• LX400 device

• Quick Install Guide

The LX400 STL is an audio over IP encoder with analog audio I/O and AES output on StudioHub (RJ45) connectors.

See here about StudioHub: https://studiohub.com.

Installation

STEP 1 Connect the Audio Equipment

The LX400 STL provides balanced line level analog audio I/O and AES output on StudioHub (RJ45) connectors, to be connected to a mixer, an FM modulator/transmitter, an amplifier, etc.

You can listen the IP address of the device directly after reboot played on the analog and digital audio output (https://help.barix.com/knowledgebase/what-is-sonicip).

STEP 2 Connect the network

Connect your LX400 STL to the network using a standard Ethernet cable (CAT5e or better) through the port labeled POE.

If you’ve a PoE switch or a PoE injector (802.3af compliant) you don’t need to use an external power supply.

STEP 3 Boot the device

After to have connected the Ethernet cable to a PoE device or to have plugged in the power supply, the device will boot:

• Right after power-up left status LED is red (boot in process)

• 5s after power-up → left status LED starts blinking and right status LED is solid red

• about 15s after power-up → Device announces its IP Address over the analog and digital audio output (take note to be able to enter the web interface later) → Left LED turns from red to green

• about 30s after power up → Application is ready → both status LEDs are solid green

LX400 STL is ready to be configured.

Note:

You can connect PoE as well as an external power supply at the same time. The equipment will use the power sources as redundant sources without the need for interaction.

First Configuration

1	From a PC in the same network subnet of the device, use a web browser to access the web interface by typing the IP Address into your browser. There are two ways to find the IP address of the unit: Download the Barix Discovery Tool at https://help.barix.com/tools/discovery-tool. Connect the audio output to a speaker and listen to the SonicIP announcement at boot up.
2	Login is required, by default user is "admin" and the password is provided on the sticker on the backside of the device (PW label).
3	On the “Home” page you get information about the application status. You should see “Standalone STL” on the top of the page and Application Status “running”. That means the device is prepared and ready with the correct software. If you don´t see, then make your device is connected to the Internet and click “Sync”. Thereafter the device will validate the software state with the Barix registration server.
4	Go to the “Local Config” where you can configure the STL application settings. First of all configure the Device type (Encoder or Decoder).
5	When done, click “Save Changes ”. Important: If you have the FLEXA AGENT enabled, and then try to change the configuration you will get the following warning (see above).
