5.1.5 LINK CONFIGURATION
The Link Configuration screen is accessed from the Link Configuration icon on the User Configuration screen. Link
Configuration allows the user to view and edit Guardian’s Link Configurable parameters. For more information on
Link Configurations, see Section 1.3.
Need to add another screenshot of the Default Tab and explain how it works similar to how the help file does this.
Figure 5-6 – Link Configuration Screen
The Guardian allows you to configure up to eight (8) separate Link Configurations for the unit. The Link
Configuration the unit utilizes is selected by the Configuration Select lines on the User connector.
Link Configuration settings are modified from three sections on this screen: Modem Settings, RF Link, and COM
Port. When desired parameters in each tab window have been adjusted, select the Save Changes button to store
the parameter information into local PC memory and exit the screen. Clicking Cancel exits the screen without
modifying any parameters currently stored in local PC memory. Clicking the Default button next to a selection will
force that Link Configuration to choose the setting from the Default Configuration.
