Projector Control Plugin

[Bshaver]

I realize it is after the season but I've made some improvements to the Projector Control plugin.

The ability to add configurations for multiple projectors and you just select your model in the drop down.

You then schedule the 'event's in the playlist as you would any other event to turn the projector on, off, hdmi in 1, video in 1.. etc.

This is working fine with my main projector and 2 'test' projectors.. I only have one model projector and would like to populate it with other projectors for those of you out there to use.

The theory behind all this is if you have multiple FPP's in a show network and have different projectors ... one FPP could have Brand X, the FPP have Brand Y you could configure the plugin properly and it would know how to control it's local device.

Please send me your codes for the various functions if you would, or post them here for others to benefit.

ON
OFF
VIDEO
HDMI
PC/VGA1
PC/VGA2
BLANK?

I understand that some projectors also allow for QUERY of what they are currently doing. If you have those please send them as well along with their valid responses.

Thanks

I'm working on this plugin, and if you would like to benefit from this, please send me your model of projector and the various codes for On/OFF/ input selection, etc.

Thanks

I am looking to purchase an inexpensive projector for Virtual Santa but want to power on/off via FPP.  What feature should I look for in the projector to make sure it will work with your plugin?

Thanks for all the work you are doing on this!

[Bshaver]

No worries.
It needs to have a serial or ethernet control port.

And, if you have access or can research the manual and get the adminitration / advanced control manual to show you the HEX codes for remote control that is all we really need.

Some of the projectors have  a warm up cycle, or even a 'mute' of the bulb option as well. Because you sometimes may have to get crafty with the timing of events to make sure the projector is ready for when you want to show your video.

I am looking at a used Mitsubishi EX320U-ST and it does support PJLink which I see a number of other users on the Forum using with FPP to control their projectors via command line scripts.  Does your Plugin have the ability to use the PJLink commands or should I research the actual hex codes for this specific projector?

Here are the commands for an Epson powerlite 500
Power on       pwr on
Power off       pwr off
HDMI input    source 30
RCA Input      source 41
comp input    source 10
pc input         source 21

[Mharnish]

Here is what is listed in the Mitsubishi EX320U-ST Projector manual for the PJLink commands:

POWR Power control
0 = Standby
1 = Power on

POWR? Inquiry about the power state
0 = Standby
1 = Power on
2 = Cooling down
3 = Warming up

INPT Input switching
11 = COMPUTER1
12 = COMPUTER2
21 = VIDEO
22 = S-VIDEO
31 = HDMI

INPT? Inquiry about input switching

AVMT Mute control
10 = BLANK disable
11 = BLANK enable
20 = Audio mute disable
21 = Audio mute enable
30 = BLANK and audio mute disable
31 = BLANK and audio mute enable

AVMT? Inquiry about the mute state



Is that what you need to add it to the plugin?

Thanks,

The first iteration of the plugin is using HEX. However; that said. it also needs to know the baudrate, stop bit, start bit, etc of the device it is connecting to.

Assuming the wiring is all accurate, and it will allow for these commands to be sent it appears as 'plain text'. It should be supported.

The plugin allows for projectors to be added to the library and will automatically create the proper EVENT files so you can add that to theplaylist to do the action that you want.

I know the plugin works with HEX and would default to that, but if there is special interpretation with PJLINK. I have not looked into those details or how to achieve it.

I'll do some googling

Thanks

Also appears that there is a PJLINK Perl library that could be used as well. This should work!

Ben / Mark -
I think some others on this forum maybe using PJlink with the scripts I worte last year. We may need to post the question to see if anyone has the codes working. I don't think either of my projectors support PJLink.

If the PJLink commands will not work with the plugin here is the PDF with the HEX codes for the Mits EX320U-ST.

If you can get it working with PJLink I think it will open it up to a large number of projectors without any modifications as PJLink is pretty widely used. 

Thanks again!

[Bshaver]

I agree, and I think that you just signed yourself up to test with... When are you expecting to get the projector in your possession?

[Mharnish]

I ordered it yesterday off eBay so I would imagine next week some time but you never know, it all comes down to the seller.

FYI, I am new to FPP this year so I have not worked with actually setting it up yet.  I bought a Rasp Pi 2 and did get FPP installed to the point I could connect to FPP on the Pi 2 via the browser but I have not done anything else.  I am more than willing to test but it may take more hand holding than someone with more experience using FPP.

No worries. the addition to this hobby will get you consumed quickly. Before you know it, you'll be having matrices for this and that and this and that also!

Welcome to the cult! LOL

Don't worry I am getting pretty engulfed already   LOL

I will let you know as soon as I get my projector and we can test out the plugin.
