Control of Barco 808?

[Ron]

You are probably looking for the serial plugin that Mark wrote.

http://www.girder.nl/download.php?Link=34

You can find setup files for this plugin here:

http://www.girder.nl/serial.php

Sadly there are no files for the barco, but i
bet there are people around here or on the avs forum that can help you from here!

Is there a manual that shows the AMX/Crestron programming stuff for the 808 on-line? This is the same information needed for the plugin mentioned above. If you can supply a URL, I might be able to point you in the right direction. :smile:

Hi!
I just bought a Barco Graphics 808 (beautiful picture, blew my Sharpvision LCD out of the home theatre) and I wonder if it's possible to control it from Girder. I've got the basic (free) projector control software that Barco makes, and it works fine. But I can't seem to find any hotkeys for the functions, and I have no idea how to route commands to it in another way. I'm no programmer, that's for sure! :smile:

I hope you can help me. Thanks a lot in advance!

Thanks!
But I hope somebody can help me out, since I have NO idea how to program anything more complicated than a VCR timer (I know they're supposed to be the hardest thing in the world to program, but... :smile:

[Mastiff]

Yi-ha!
You gave me an idea, and my hunch paid off! I found the full list of communications on

http://www.barco.com/projection_systems/customer_services/downloads/pc_cmds.pdf

So in other words friendly Barco hadd the info all along! Tonight I'll see if I can get anything out of that serial plugin. It looked kind of difficult, but I might get lucky... :smile:

Thanks for the helpo, dudes! (was that sufficiently young and hip?)

Hi Mastiff,
Did you get your barco to work with the serial plug in, I have a Barco 708 and it work ok, can send you the strings if you wan't,
I only one that i can't get to work is the Pause which would be niced

Here it is. You need to change the serial port in the ini-file, since I use port 3 which you probably haven't got on your computer. Just import it in the configuration part of the serial plugin. Oh yes, there's some norwegian special characters in the names of the commands, but that should not be a problem. Let me know if it works for you!

I have automated my Barco 808 too with Mark's wonderful plugin.

One question mark I send codes to the Barco it will send back a response after any command which you can parse for further staus info and/or request status back which triggers various parsing using GVMS of the returned data.

The status command tells me what input is selected and whether power is on so that you don't send a standby command to turn it on when you want it off etc. Also knowing input means you can change inputs or memory settings only if necessary.

Sometimes the data is 14 characters and sometimes it is 16 or 7 or 8 bytes. The reception of data occassionally truncates the first byte this occurs on other status requests I do to for other devices but is consistant on the Barco.

Do you have an explanation or potential fix?

I have had to use strlen(barcodata); command to test for length of received bytes.....to me it seems sometimes Girder is busy when this occurs.

Thanks Rick

Sorry, but I haven't tried on feedback from the Barco, I was satisfied with just controlling it. But do you know how to access the 90+ sources? I want source 95, since five's the input I use, and then 95 can be another aspect ratio (full screen) while I keep 16:9 on the 5 source.

Hi Mastiff,

should there be a link in your last post, would be interested in you Barco .gml, could you link it or send it please.
Iam on com 1


thanks

[Mastiff]

It's there, even tough it's supposed to be 0 kb. Just download it, and edit the ini-file.

[s.morris]

Thanks Mastiff,

will let you know

Hi Mastiff,

I have the same string as you but mine is all together and the pause does not seem to work, but all other are ok

String is 0200010F000000001C

Rick -

I don't have an explaination. The serial plugin simply pulls data out of the Windows driver and hands it to Girder.

Does the Barco (or your other equipment) use any type of handshaking to better coordinate TX/RX? Maybe we are getting into an over-run condition in the COM port hardware FIFO?

I've built a version with some extra error checking. Could you try this and tell me if you get error popups?

[rickd]

Thanks Mark I'll give it a go in the weekend cheers Rick

Yes, I'm pretty sure all my functions worked when I made this group. But I never use thhat function.
