[. . . ] If this error code is returned, send the same command again. When the projector cannot execute the received command. 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". [. . . ]
