Craft ports
The NetGuardian-16S has two craft ports, one for each of the unit's two internal circuit boards.
The upper craft port is used for : 1) connecting a PC running the Edit16S configuration software via a COM port
connection; 2) accessing the NetGuardian-16S TTY configuration interface; and 3) loading firmware updates to
the upper circuit board.
The lower craft port is used for loading firmware updates to the lower circuit board.
