TCP/IP Connection
Before controlling via LAN, it is necessary to establish connection of the TCP layer by a “3-way handshake”, followed
by sending out “PJREQ” and receiving “PJACK” within five seconds after the projector sends out “PJ_OK” for connection
authentication.
If you are unable to complete sending within five seconds, or when “PJ_NG” or “PJNAK” is received, check the operating
status of the projector, followed by performing the steps again starting from establishment of a TCP connection.
