Hello,

I am in charge of 10 centre of information on nature in a french national park.

We just bought few HD2000, some to be connected to full HD beamer in small projection room, and some to be synchronised beetween them.

For this last subject, we have 3 x 42'' LCD in 1360x768 abreast to show 4 shows of 3'. The 3 x LCD represent like 1 big LCD of 4080 x 768.

The visitor touch a touch screen to choose one of the 4 small show.

Actually we have 3 PC in a network and a special software Wings Platinum to pilot the all... but we have many problem with the network, the touchscreen, the... windows microsoft !

so...

We decide to change the PC with 3 HD 2000.

And to simplify in a first time, we are going to study 2 options :

a) command with 4 buttons like GPIO : the visitor click on one of the buttons.
b) command with a mouse : The visitor click with the mouse on the center LCD where it will have a display menu with the four choices.

And if i read in the forum that was possible, and in the website the "How to : synchronize multiple displays...", it's a little bit short.

Do you know where i could find this documentation on this point ?

I'm not a proggrammer, but i could programm some simple scripts... or use .csv file like in the how to.

a little bit long this message <!-- s;-) --><img src="{SMILIES_PATH}/icon_wink.gif" alt=";-)" title="Wink" /><!-- s;-) -->)

thanks a lot.

  It wasn't clear if you wanted to sync over the network, but I sent you an example that uses GPIO.
  
  There are buttons for each video, and the menu. The master sends a signal when it plays each file.

  I though to sync with serial or other way, but not the network.
  
  
  
  To use a network, you must use a switch or a hub ?
  
  
  
  Is it the same result, in fiability, in quality of sync ???

  With the HD2000, I need to verify if they autoassign an IP address if there's no router. THey mightn not. I would say the GPIO would get you the best results.

  ok, so lets go for gpio !
  
  But in that case, how i sync the 3 HD2000 ?
  
  In using the DB9 RS232 with special cable (using 3 DB9 and 2 cables beetween them) ???
  
  
  
  HD2000 N°1                        HD2000 N°2                      HD2000 N°3

  The GPIO port isn't a serial port. I'll forward a diagram showing one way you could connect usings together. The gpio port has 6 outputs, and you can connect three units to each output on the master. In your case, you would be connecting each output on the master to an input on the slaves because you want to be able to trigger multiple videos.
  
  
  
  For example, output 0 on the master could be connected to input 0 on slave 1, slave2, and slave 3.
  
  
  
  Output 1 on the master could be connected to input1 on slave1, slave2, and slave3.
  
  
  
  And so on. I'm emailing the diagram for the gpio port.
