[. . . ] Although the projector receives the commands, it in some cases does not execute the commands. This projector sends various codes other than the return code. When having a control sequence by RS-232C, reject other codes from the personal computer. · Although the projector sends out the return command, the command may not take effect in the following cases. (1) During signal switching (2) In the process of the auto position (3) After the power is turned on. [. . . ] Note, however, that the response becomes slightly slower than when using the RS-232C terminals.

(Turn on the circuit breaker or main switch. ) · Not connected with the projector. Check that the RS-232C cable is connected. Check the RS-232C cable for electrical discontinuity. · The projector is in the state of being unable to send out a command. Use command "00vST" to check if the projector operates normally. Note: In the following conditions, the projector does not respond even if it operates normally. xb7: Lamp cover open error xb8: Filter cover open error xb9: States of other component abnormality Error status vER 76h 45h 52h The PC sends the command without attaching the data code to it. On the other hand, the projector attaches to the received command its current operating status as the data code and send it back to the PC.
