PJLink Troubleshooting

mark

Here's a special version of the PJLink actor that will output a "log" of the communications with your projector.

1) Set up all the parameters to talk to your projector, make sure it's at least trying.
2) Leave the scene and come back to clear the log output
3) Attempt to send a message to the projector
4) Click the 'log' output and copy all the text inside
5) Paste that text in your response to this message

NOTE: THIS IS NOT THE NORMAL RELEASE VERSION OF THIS PLUGIN! INSTALL THIS ONLY IF YOU NEED TO DEBUG COMMUNICATIONS WITH YOUR PROJECTOR!

Here's the plugin:

send-pjlink-mac-debug-output-v3.zip

You need to install this plugin at /Library/Application Support/TroikaTronix/IsadoraPlugins_x64/ -- move the existing Send PJLink actor somewhere else, and install this special version instead.

Thank you! I tried using the custom PJLink actor, unfortunately I don't see the log output. I tested on a Mac with a fresh install of Isadora 3.0.7. (so no risk of mixing up the custom actor with the regular one). Also tried Windows but it seems the custom actor is not working there. Is the log output supposed to be part of the actor (next to "response", "error" and "recv response")? Or should I look somewhere else?

Sorry, my bad. I uploaded the wrong plugin. Please download the file send-pjlink-mac-debug-output.zip from the post above and install it as instructed. This plugin is macOS only. There is no Windows equivalent at this time.

You'll see that it has the log output as shown here.

Hey,

I downloaded the PJLink actor and connected the Optoma ZH406ST to the network.

Log when sent "Power On"

Process 0x7faa21556520: cmd '%1POWR' - param = '1'
get host name
create socket
connect to socket
wait for connection response
get response
shutdown socket
close socket
close socket err = 0

Log when sent "Power Off"

Process 0x7f8d793c5740: cmd '%1POWR' - param = '0'
get host name
create socket
connect to socket
wait for connection response
get response
shutdown socket
close socket
close socket err = 0

If you need any other commands sent just let me know.

Well, shoot. It didn't print out the actual message sent back from the projector so I can see what is wrong with it.

I've made an update to ensure that information is in the log and tested it with the emulator. So please try again. Sorry for making you do it twice.

Best Wishes,
Mark

No problem. Thx for your help!

Power Off:

Process 0x7fc324ef2960: cmd '%1POWR' - param = '0'
get host name
create socket
connect to socket
wait for connection response
received initial response: >>>pjlink 0
<<<
initial response doesn't start with PJLINK
shutdown socket
close socket
close socket err =

Power On:

Process 0x7fc32261e320: cmd '%1POWR' - param = '1'

<<<
initial response doesn't start with PJLINK

Is the request terminated because PJLINK is not in caps ?

Yep. That's it. I'll change the code so that it does not care about capitalization.

OK. Hopefully this will solve it. This is still with the log enabled. Once we prove it works, I'll remove that.

Well done! Works. I could turn the Optoma on/off

Process 0x7feb5c28dd20: cmd '%1POWR' - param = '1'
get host name
create socket
connect to socket
wait for connection response
received initial response: >>>pjlink 0
<<<
STARTUP SUCCESS
send pjlink command = %1POWR 1
wait for response
received response: >>>%1powr=OK
<<<
ensure response starts with %1
check that response command matches sent command
shutdown socket
close socket
close socket err = 0

I'm back from some time off the grid, it's wonderful to see the problem has been resolved in the meantime! Heartfelt thanks! Isadora rocks, the software and the people behind it!

Would it be possible to get a version of the plugin with the log disabled, and also a Windows version? Our final piece will run on Windows.

We'll make sure to post images + video of the piece as soon as it's up. It's a permanent interactive public art installation in the 6th district in Vienna.

Thank you!

Mark's going to be unavailable for a little while, but I'll bring this up to him as soon as he's back.

Hi there Maki, I also created a custom PJLINK actor that can be found for Isadora 2.6.1. It still works for Isadora 3, and that way you may still use PJLINK if we don't hear back from Mark in time.

Could you let me know what your timeframe is that you need a solution ?

Cheers!

Maki

@juriaan @Woland

Ok, no worries! We install on August 29th, it'd be amazing to have a solution by then but we'll manage if it's later than that. The actual launch will be mid September.

I'd love to try the alternative PJLINK actor, where can I find it?

Cheers!

I think this is it

@woland

I think you are right

Unfortunately it's unlikely that Mark will be available to get new plugins to you by this date. We suggest going with @Juriaan 's solution for the time being.

@woland

Ok, no worries! In the meantime I used @Juriaan 's plugin. It works as a temporary fix. Thank you!

Juriaan

@maki

Great to hear that it works for you

The updated plugin (v0.9.5) for both Macintosh and Windows is now available on our plugins page.
