Run Programs from External Storage
Certain 4-Series control systems are equipped with external storage ports. On system boot or a
hardware reset, the control system checks for any programs in external memory (if installed)
before checking in internal flash.
To configure running programs from external storage, use the Compact Flash function in
Crestron Toolbox. For more information, refer to the Crestron Toolbox help file.
