Command Control FAQ

1. With my PT-EZ590 Series projector, when I attempt to transmit control commands using [Command Control] in the [Network Control] menu, communication is automatically terminated, or control commands can’t be transmitted sequentially and an error appears. Why?

For security reasons, PT-EZ590 Series projectors have a communication specification that prevents unauthorized or malicious third parties from operating the projector. It requires network connection request processes for individual commands. The projector automatically terminates network communication just after a command response is sent, even if the projector does not receive a disconnect request from your control device software. To transmit commands sequentially, you need to configure individual control command network connection request processes within your supported control software.
