Hey, new here, but I've been lurking for years. This place is a treasure trove, love it.

I'm the lead technical person in a small one screen theater. We just recently went to digital without a VPF program. It was a big leap, our last sound processor was a Dolby CP-55, and the projector really should have been sent to a museum a while back.

Quick question. I'm trying to automate things more. I'd like to put the projector in standby mode after it's cooldown period with a command from the Doremi server, but the library of commands for the projector are a bit limited.

I found in the Christie manual there's an appendix of Serial API commands, but there's nothing I can find in the manual about how exactly to use these commands.

Do these have to go over a serial cable, or will the ethernet connection do? Our booth network has no connection to the internet or wireless, so security's not an issue.

Any help or condolences will be greatly appreciated.

Hi Dean,

try the following:
* create a raw device for your Christie chassis
* issue raw TCP orders to this device to turn it on/off

Creating a raw device: raw device using TCP on port 5000. IP address is the (Christie) projector IP address.

Useful orders:
* power off: send TEXT command "(PWR3)" to the raw device you've just created
* power on: send TEXT command "(PWR0)" to the raw device you've just created

Consult Christie support for more (I encourage yourself to registrer your projector and ask for a support account to keep current with Releases Notes and Erratas).

Have nice shows with your CP2220 [Wink]

Cheers,

And, to the best of my knowledge, sending a powerdown signal immediately after "lamp off" is OK as the projector will wait for the cooldown to complete before actually powering off.

I confirm.

To be just near perfect, you'll still have to take the (lamp) extractor motor electrical switch enslaved to... an Integ JNIOR (or alike), and you'll have a full automated booth [Wink]

Thank You, I'll give that try.

We actually have a jnior without anything hooked up to it. Sad, eh? I am planning on mechanical relay switches for the fan and the amps. We've got a couple relays on hand, but they're the normally open type. And if something were to mess up with the jnior or the server I'd really rather the fan relay fail in the on position.

Now just need to find a way to automate ticket sales, concessions, cleaning, and business plan updates. :^)

can you switch the Christie on through doremi? The problem is that once the TI board has been switched off and the projector is in standby, there is a "projector communication failure" preventing any playlist to be played. You can turn the projector on manually executing the macro, but you cannot automate it AFAIK.

Yes you can. You can pretty automatize completely a screen - Christie's projector have been designed to do so.

That's great, could you tell me how you switch a Christie on from a doremi without manually operating the macro?

Thanks again. Now, will putting the projector into stand by mode lead to marriage problems? Or does that happen if we turn the projector all the way off?

I think we got a pretty good traveling marriage counselor lined up, but I'd hate for us to have any down time.

if you put the projector in standby you turn the ICP off, hence the "projector communitcation failure" (that's not a marriage problem anyway).

Doremis can have macros being executed automatically on power-up. But depending on what you really want to achieve, an external automation might be better.

but servers are not supposed to be turned off, as extensively discussed on this forum as well.
How can I schedule a macro to be executed without using a playlist on a doremi?

What kind of 'schedule' should that be on a server without a running playlist? Why should the server take over this job? There are ways to execute macros from the shell or through cron jobs. I just don't think it's a good way to do it. This is not exactly a technical issue, but a logistical/workflow question.

Carsten,

Maybe we are misunderstanding each other.
I understand that a doremi can turn a projector on - I've just learnt that a projector can turn itself on following a schedule BTW.
But what I mean is that in a world where everything is run by managers I was wondering whether a server could turn the projector on without human intervention.

Now the question is still valid: can you fully automate a projector - without turning it on by keyoboard, or without scheduling another week into the projector itself?
