It is possible to control this unit by connecting it to a PC using an RS232C cross cable (Dsub 9pin).
The projector can be controlled by connecting it to a PC through the computer network with a LAN cable for control commands to
be sent to the projector.
●
To control using the computer, connect to any one of the terminals (RS-232C, LAN or USB). Do not use the terminals at the
same time.
●
Please use it after you have gained proper understanding from professional books or consulting the system administrator.
RS232C Specifications

PC refers to the controller, such as a personal computer.
TCP/IP Connection
Before controlling via LAN, it is necessary to establish connection of the TCP layer by a “3way 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,
