Attention
f
The projector cuts off the network connection automatically after transmitting the command (the received data). This function is used to
implement the security policy for the protection against unauthorized operation of the projector by a malicious third party. If you want to
transmit the commands continuously, transmit the commands every time after network connection is established upon request.
