4.7 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 pro-
jection 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.
