OperationManual

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,
