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. Bind this received 8 bytes and the authentication password and digest this data with the MD5 algorithm and add this in front of the commands to send. Following is a sample if the authentication password is set to "password" and the random 8 bytes are "a572f60c". 2) Receive the random 8 bytes "a572f60c" from the projector. 3) Bind the random 8 bytes "a572f60c" and the authentication password "password" and it becomes "a572f60cpassword". 5) Add this "e3d97429adffa11bce1f7275813d4bde" in front of the commands and send the data. 6) When the sending data is correct, the command will be performed and the reply data will be returned. 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. 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.
