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 specied 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. In such a case, check the sending code and the setting status of the projector. (4) Data reply : 1Dh + xxxxh When the projector receives the GET command correctly, the projector returns the responce code and 2 bytes of data. NOTE · For connecting the projector to your devices, please read the manual for each devices, and connect them correctly with suitable cables. · Operation cannot be guaranteed when the projector receives an undened command or data. · Provide an interval of at least 40ms between the response code and any other code. · The projector outputs test data when the power supply is switched ON, and when the lamp is lit. · Commands are not accepted during warm-up. · When the data length is greater than indicated by the data length code, the projector ignore the excess data code. Conversely when the data length is shorter than indicated by the data length code, the projector returns the error code to the computer. 10 Command Control via the Network Command Control via the Network When the projector connects network, the projector can be controlled with RS232C commands from the computer with web browser.
