      So we beta tested the PJ Link application before, and we tested it with the Test application and a few projects that I and others had lying around that where PJ Link enabled. Like you can imagine, we haven't tested out every single projector in the market. But if a projector is not sending PJLink commands in the order / described as in the protocol documenation then you can hardly say that Isadora is the fault ;) This is a Projector error. Regarding why it works with the Test application, it seems that they are not validating the response from the Projector to verify that it is as described in the protocol documenation. Could Mark add a way to still make it work with your projector, I think so. Some kind of hidden input field with an option to disable verifaction would already go a long way for your use-case / projectors.

      Could you log the above ? It is kinda a bug-report / feature request.

        I am happy to make an update to the Send PJLink actor, but I'm going to need some documentation on the replies that are actually being sent. Unfortunately, I don't have access to the models of projectors you mention, and so it's sort of impossible for me to try this and find out what's happening.

        I guess I need to implement some way to write out the transactions.

        (Sidenote: @Maki it is the convention in this forum to add your primary operating system and hardware to your signature line. Could you please add that? Having it there would have saved me from asking the next question.)

        Are you running on macOS or Windows?

          Thank you! That's amazing. I can provide our Optoma projector for testing (based in Vienna), or give remote access to the computer connected to it. Or run tests and report the results.

          Regarding OS, I work with both Mac and Windows. This particular project will be run from a Windows PC. Will add this to my signature. Conventions are important :)

            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.

                        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

                                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!

                                    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!

                                      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!

                                             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.
