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?
