7) Password lock commands
The password lock commands control the password lock. The password lock enabling or disabling command is
sent with a 4-digit figure (password) 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.

received command its current operating status as the data code and send it back to the PC.
