15. Security Lock
15.1 Security Lock Control
This command sets the condition of security lock function to "LOCK" or "UNLOCK".
If security pass codes 1st to 4th are matched with monitor resisted pass codes, then this
command is executed, and reply no error status and a new condition.
If codes aren't matched with them then setting isn't changed, and reply error status and a
current condition.
If the monitor receives this command while waiting for Pass codes inputs, then it only checks
Pass cords (and releases image muting if Pass codes are OK) and doesn't apply "EN" parameter.
1) The controller requests the monitor to set the condition of security lock.
