6) Password lock commands
The password lock commands control the password lock. The password lock enabling or disabling command is
sent with a 4 to 8-digit password comprised of any figures 1 to 4 added to the end of the data code. When the
password lock is enabled or disabled successfully, the projector sends a return command comprising the data
code, password, and “1” at the end. When enabling or disabling the password lock fails, it sends a return
command with “0” at the end. There is no reconfirmation of the password. The password input command is for
enabling projection of image when password lock has been set to DISPLAY INPUT. The password input
command is sent with a 4 to 8-digit password comprised of any figures 1 to 4 at the end.
**** is a 4 to 8-digit password comprised of any figures 1 to 4.
