@dillthekraut Didn’t look as far into the model info, good call. As a shortcut/save yself some trouble it might be worthwhile to look into an oldie but goodie hardware solution like the wahlberg dmx shutter. Physical device, works like a charm

NEC PA653UL
Most modern laser projectors doesn't come with a physical shutter anymore, but dim or shut down their light source, or simply blank the picture. The bigger ones offer to decide between those options.
While the light source/laser off is comparable with the physical shutter, the picture mute is not, as it still gives the minimum light of the projector, often resulting in a 'glimmer' where a true black is needed on stage. There often is a menu setting to switch between those modes.
A quick look into the documentation reviled following (it really was just quick, I might be partly wrong):
1. There are separate remote buttons for those functions on the remote.
2. the PJlink documentation has contradicting information.
While the 'supporting command list' says only the mute function is supported, but not the shutter (NEC calls it lens mute), there is a note at the documents head, saying later revisions (13.1, probably meaning the Firmware) do support it.
Wrapping all up, I guess there are two different commands available, but if they work depends on the firmware revision your projectors are on. Unfortunately, the pjlink documentation on their webside doesn't provide detailed information of any of those commands.
Edit: Found this document, which offers different command strings for mute and shutter.
@pauliedazzle try capturing network traffic using an app like Wireshark. Trigger the shutter in/out from the webinterface and see what happens under the hood as a starting point. Considering the fact that the other pjlink commands work and the shutter does respond from the webinterface seems to imply there’s something wrong with the syntax, not the hardware.
Thank you for your response,
I just submitted the ticket and wanted to add an update:
I changed the patch so that there is no fade when i transition between scenes and the problem no.2 is resolved. I send the previous file though so that you take a look.
I don't think this resolves problem no.1, I think it is not connected because it doesn't happen in transitions.. The problem is that problem no.1 doesn't happen consistently..
The shutters function when I click the shutter button on the LAN webpage, it's that the PJLink AV Mute commands, both the AVMT 11 and AVMT 31 only mute the image and do not engage the shutter at all. The project I'm working on needs use to be able to cue the shutter in and out. Not sure if there needs to be a tertiary program that Izzy should fire to then engage the shutters or if there is a different command that I should be sending over TCP/IP
Hey @Alice,
We would love to dive deeper into this problem with you. Could you be so kind to make a new technical support ticket at
https://support.troikatronix.com/support/tickets/new
This way we can ask for more information / ask for system logs.
Thanks in advance!
Hi!
If I grab the manual of the projector that you described it seems that you are able to turn off the shutter options of the projector; Could you give that a shot and report back to us?
According to the information you provided you have hardware connection, other Plink commands work so it is not on the communication layer between the two devices, which leaves a problem on a hardware level with the shutter itself.
Let us know :)
Currently trying to shutter an NEC PA653UL using Isadora, and running into a strange issue. PJLink is working and I can control it's power and muting, but when it comes to shutters, I am unable to do so. Currently, the only way to shutter it is via webpage access and clicking the shutter button. Been sifting through documentation and even tried an old user actor that sends hex to the projector to shutter it (along with trying a few different hex strings) and can't seem to crack it. Any advice?
Hello,
I need your help with a problem i'm having..
The patch is tested for a long time on a desktop, there was no problem.
Now I have to use a laptop for the performance because I am traveling. The performance is with 5 full HD projectors. [the 4 are a split from a 4k (something like a matrox) from the hdmi and the 5th is a tv monitor from a usbC 3.2 - display port]
I have 2 seperate problems I don't know if they connect somehow:
1. When I tested the laptop at our space with the projectors connected everything worked fine at first. The problem happened when I left it running for an hour or so. Then the buttons didn't respond and when i hit space to go to the next scene, the interface did the transition, loaded the next scene but the projectors were stuck with the visuals from the previous one. The only way to unstuck it was to force stage preview and then show stages again. I think the buttons were working and sending signals, the videos were playing, but the visual was stuck) I will check again tomorrow.
Then I tried to test it again and again, leaving it running for different periods of time and it was not consistant. One time it got stuck at 15min.
The load is not much, 10 to 30 %, and it happens to all the scenes even the ones that are just black. (nothing there)
2. The second problem is when i opened the same laptop at home with no external monitors, using force stage preview. It got stuck imediatelly in some scenes every time I loaded them. The buttons send signals to the interface, in the interface I can see videos playing if i hover the mouse, and I can see the position of the video running, I can load next scene in the interface, but in stage preview it is stuck to that scene.. With this problem I can only close isadora and reopen it, I cannot get it unstuck..
But if I put an external monitor with an HDMI and make that monitor the main display on windows, then it plays fine and we go again to problem no.1. If I make the laptop monitor the main display the problem persists. With some testing I found out that it happens if I change to the scene with space or with jump. If I click with the mouse it is fine. If I force stage preview it unstucks.
*update: I think it happens to the scenes when there is a fade to the next scene with space bar, that's why it does not happen when i click directly with mouse to the next scene. I will try to change the patch and see if it happens again.. The problem no.2 happens when the laptop monitor is the main display.
But with problem no.1 I have no idea why it is happening..
I also updated the nvidia drivers and tried both studio and game (i don't know which one is best)
I also selected isadora program in the System > Display > Graphics and chose to use the nvidia graphics card in case the problem was there..
I also changed the settings in the nvidia control panel, and for isadora I selected the high-performance NVIDIA processor
I am really worried, I don't know how long i have to leave it open before the show starts.. We also have some scenes where nothing changes for 10min. and I worry it is going to get stuck at the performance..
My laptop is running windows 11
Del G15 5525
AMD Ryzen7 6800H with Radeon Graphics
32GB ram
1TB nvme
Nvidia GeForce RTX 3060 Laptop GPU 6GB ram

outputs: 1 HDMI , 1 usbC 3.2 display port
I run the latest isadora 3.2.6
Hi,
My advice would be similar to John. Only to add that you can also use the depth camera feed to calibrate a fade-in and out based on the distance from the Kinect you want the participant to be tracked. You can define a tracking zone and trigger a change or cross fade based on that proximity. It works with a Calc Brightness module.
Best wishes
