For details of RS-232C commands, refer to RS-232C Communication / Network command table ( 17). Connection 1. [. . . ] 4. shown in figure Turn the computer on, and after the computer has started up turn the projector on. ( OPTION menu - SERVICE COMMUNICATION in the User's Manual - Operating Guide) Turn off the projector and the computer.

Response code / Error code ("h" shows hexadecimal) (1) ACK reply : 06h When the projector receives the Set, Increment, Decrement or Execute command correctly, the projector changes the setting data for the specified item by [Type], and it returns the code. (2) NAK reply : 15h When the projector cannot understand the received command, the projector returns the error code. In such a case, check the sending code and send the same command again. (3) Error reply : 1Ch + 0000h When the projector cannot execute the received command for any reasons, the projector returns the error code. Command format The commands some datum are added to the head and the end of the ones of TCP#9715 are used.

[Check Sum] This is the value to make zero on the addition of the lower 8 bits from the header to the checksum. [Connection ID] Random value from 0 to 255 (This value is attached to the reply data). NOTE · Operation cannot be guaranteed when the projector receives an undefined command or data. · Provide an interval of at least 40ms between the response code and any other code. NOTE · As for the transmission of the second or subsequent commands, the authentication data can be omitted when the same connection. 14 Network Bridge Communication Network Bridge Communication This projector is equipped with NETWORK BRIDGE function. When the projector connects to the computer by LAN communicaton, an external device that is connected with this projector by RS-232C communication can be controlled from the computer as a network terminal. For details, see the 3. 7 Controlling the external device via the projector(using the NETWORK BRIDGE function) - Network Guide. Connection 1. Connect the computer's LAN port and the projector's LAN port with a LAN cable. Connectthat you want toCONTROL portRS-232C RS-232C port of the devices control with a cable. Turn the computer on, and after the computer has started up turn the projector on. [. . . ] Turn the computer on, and after the computer has started up turn the projector on.
