STANAG Input: Edit Window
To configure a STANAG Input (also referred to as ‘Reference’), go to its Edit window. For
instructions, see: "Configuring Option Card Inputs/Outputs" on page330.
The Web UI list entries for this card are: STANAG In and STANAG In, Isolated.
The inputs are named: Stanag HQ Input [number].
