I would like to ask a question: What method should I use to add projectors from the local network? The projectors are Panasonic projectors that support the pjlink power control protocol. The power-off command is “%1POWR 0\r” and the power-on command is “%1POWR 1\r”. The port number is standard, set at 4352. The IP address of one of the projectors is 192.168.10.23, and there are also a few other projectors, such as 192.168.10.24 or 192.168.10.25.
