The administrative privilege is required to do the above operations.
Is KPG-36X or KPG-46X equivalent to the serial cable (KPG-22A, KPG-36A, KPG-
43A, or KPG-46A) in terms of the time required for writing and reading data?
If sliding the SW of KPG-36X or KPG-46X to [USB], the time required for
communication depends largely on the PC used.
Also, it may take longer if the firmware is written by using KPG-36X or KPG-46X and
the corresponding Fpro (Version 6.30 or later) or KFL (Version 1.22 or later).
