Before you can control it via LAN, you have to establish a TCP-connection via a "3-way-handshake". It is
necessary for a connection authentication to send from the projector "P

" and - within 5 seconds after
sending a "P
-
REQ"
±
to receive "P

". Please perform this operation
±
after con
¿
rming the operating
status of the projector - again after establishment of a TCP connection, if you cannot send within 5 seconds
