The projector can also be connected to a computer network by connecting it with a LAN cable and sending the proper control

TCP/IP-Connection
Before you can control the projector via LAN, you have to establish a TCP-connection via a "3-way-handshake". It is necessary for
a connection authentication to be sent from the projector "PJ_OK" and - within 5 seconds after sending a "PJREQ" – to receive
"PJACK". Please perform this operation – after confirming the operating status of the projector - again after establishment of a TCP
connection, if you cannot send within 5 seconds "PJ_NG" or could not receive "PJNAK".
