Command 0x001C – Deactivate slave reset when changing to the protected
mode
8828
When changing from the projection mode to the protected mode, all slaves are normally briefly reset
(reset or offline phase). This may lead to problems when the system is running. In such cases the
"deactivation of the slave reset" prevents the short deactivation of the slave outputs during changing of
the operating mode.
