FAQ

→ What to do first after receiving the streambox?

You must register first your stream (streamname, and other informations) on the on-line Locustream form.

For that read first the Locustream guidelines (registration, etc.) here :

→ What items are required for the installation?

In order to install the LocustreamBox + LocusMic you need :

- Compact size AC adapter (see below)

- DSL connection

- an ethernet cable

- (an electret microphone if you don't have the LocusMic)

- mini-jack audio cable extension (jack 3.5, male/female)

and temporarly :

- a VGA monitor

- an USB keyboard (whatever the selected language, you can select it on the Pd patch)

- an USB mouse (PC)

and to fix some ground-noise which can appear :

- a wire more or less long depending on the distance between the streambox and your electric plug (if you've got a ground/earth pin) or a metal 'thing' which can make an efficient ground.

→ What type of power supply does the box use?

Ideally: Compact size AC adapter, saves space on power strips. Input voltage 100-240 V AC, 47-63 Hz. Output voltage 18 V DC, 800mA or more. High efficiency. 2.1 mm jack, center positive. So any 12volts adapter that is in the range of the 800mA and the 1A will do oke. And yes, It can be powered via PoE (power over ethernet)

→ What steps should I follow when I receive my streambox?

• 1. connect a network cable that has internet connection, VGA monitor (blue connector), keyboard and mouse.
  • note : You can use an apple keyboard with apple mice. But be careful the right-click requests various methods depending on your Apple mouse type.
    • with an optical Apple mouse : shift + click
    • with a mighty mouse : read this video :

• 2. plug the juice (electricity power), follow the boot process or, in case you have no screen, wait for at least 1-3 minutes then,

• 3. if you have a screen, you will have the chance to see the puredata patch, use this 3 boxes to input your information. Is important you click enter after you enter your data. If the infos remain in the box, it means they where entered properly, if they dissapear please repeat the process. Click the box, enter your info, click ENTER.
  (If you haven't got a screen : SSH access)

• 4. check on this page to see if your stream gets listed, reload the page after one minute in case is not there: http://locus.creacast.com:9001/ - The pd patch will also tell you if the stream is up, with the pages sent status.

• 5. plug in your microphone or the LocusMic :

• 6.Then adjust your sound level in the patch. When all is ok, SAVE your patch (in order to save all your settings)

• 7 finally open with VLC your stream URL, get it by right clicking on the icon of the speaker and copying the link. Proceed to VLC for pasting it inside the http field of the window that VLC opens when you do ctrl+n:

• 8. you will be able to listen to your own stream with the delay of the signal bouncing back from the icecast-streaming server in France. At this step you can adjust again your sound level.

• 9. as soon is up and your are happy, report it to the Locustream mailing list.

Learn to power off the box from within the software option, aka shutdown, found under right click.

TRY AVOID UNPLUGGING THE BOX WHILE THE SYSTEM IS RUNNING.

→ To shutdown or reboot the machine please use the menu that appears with a right click anywhere on the desktop:

-Is this box autonomous: it doesnt need any computer, only an internet connection (ethernet) and a mike?

It is a small computer in itself, a silent one since it doenst need a fan to cool itself. it has a sound card, video out, 2USB and a network card.. so yes, its like plug and play for the streams.

→ Is it possible to configure my own IP adress and DNS?

The first thing to try is to click on the little last icon up in the right corner, this will bring up the network manager where we can hopefully configure a manual network connection, the icon looks like this one below:

→ How do I move a window?

Press the command key and drag the window with the mouse.

Bugs Report

What if i get few and in red FAILED errors when the box is booting?

→ please read this log:

If when the streambox restarts you've got this message :

SYSTEM BOOT FAILURE. INSERT SYSTEM etc

The fact that the Flash Card (FC) is unplugged could be the cause. The first thing to do is to shake the box to listen if there's like something flying around. Smile : it's a remake of a famous work by Marcel Duchamp : "A Bruit Secret" :

Voice of Marcel Duchamp

Joking apart, you need to take out and put in again the CF card in the streambox. (Open carefully the streambox with the help of the screws)

Only for people with a streambox from the first release, (Version ?.? : KRN-Dakar, Björn-Solleftea, Jérôme-Nice)

you might need to take the little jumper cable from the monitor output out to connect a monitor and see/fine tune the patch to your microphone level inputs:

is somehow important that you dont turn on the device without that little connector, is a BUG im trying to fix now. THE BUG WAS FIXED WITH A BIOS UPDATE

How to minimize the ground noise ?

Most of the streamboxes have a small amount of ground noise. I'ts kind of a shame because the sound quality, especially with the new microphones (LocusMic) is getting quite good. If you have a screen plugged into the streambox its mains connector automatically provides a ground, however when you take the screen away, since the streambox only has a 2 pin mains adapter that nasty ac buzz appears.

You can finally got rid of all ground noise by running a long wire (depending on the distances) from the streambox to the ground pin of one of an available electric plug. If there is no earth on your main electric installation, you can fix the wire with one of the screws on the serial plug to a metal 'thing' which makes a very efficient ground.

Another important tip : to keep your mini jack extension cable (on which the LocusMic is plugged) as short and as good a quality as possible. The cable could be responsible for most of the noise. It's better to have a long ethernet cable and a short audio cable, than the reverse. So by moving the streambox without modifying the microphone' localisation and your DSL connection access, that could solve this problem of ground-noise.

Here is an easy way to remedy it using a jump lead which is easy to find in any electronics store:

Terminal commands

open the terminal : Windowskey+F1 or AppleKey+F1 or ctrlkey+F1 and type:

xterm

shutdown the streambox :

sudo shutdown -h now
