When the projector cannot understand the received command
When the projector cannot understand the received command, the error code ‘15H’
is sent back to the computer.
Sometimes the projector cannot properly receive the command. In such a
case, the command is not executed and the error code ‘15H’ is sent back to the
computer. If this error code is returned, send the same command again.
When the projector cannot execute the received command.
When the projector cannot execute the received command, the error code ‘1cH’
+ ‘xxxxH’ is sent back to the computer. 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, an error code will be returned to the computer.
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.
• The projector outputs test data when the power supply is switched ON, and when the
lamp is lit. Ignore this data.
• Commands are not accepted during warm-up.
