Serial ports, if activated (click HERE), will show up in Logical view, but only serial ports that have a device physically connected will appear in Physical view.

If an RS‑422 serial port is configured to ‘None’, it will not appear in iC Navigator. iControl treats such a port as a standard RS‑422 port, to which a third-party device (e.g. a router) can be connected.

A reference configuration is a feature of iC Navigator that allows you to keep track of important cards, or groups of cards. If a card is removed from a slot, the default behavior in iC Navigator is for the card to disappear from the list in Logical view and Flat view. In Physical view, the device name is replaced by Empty Slot.

But iC Navigator allows you to designate a card as part of a reference configuration, so that the name of the card and the slot number it occupies are retained. If the card is removed, it will be visible as before, but with the description Missing from slot beside its name.
