• If the User ID/Password property is empty, then the User Logon dialog is displayed. The entered User
ID and Password are verified on the device to be connected. If either is invalid, an error message is
displayed, otherwise the Impact Connector is connected to the device.
• If a valid User ID and Password have been linked from the UserID\Password property of another
Impact Connector, then the User ID and Password are verified on the device to be connected. The
User Logon dialog is not displayed. If either the User ID or Password is invalid, an error message is
displayed, otherwise the Impact Connector is connected to the device.
If there are multiple Impact Connectors in one Control Panel, and security is enabled on one or more of the
devices, the designer has the option to do one of the following.
• Device Connection with Multiple Logon Dialogs: If each Impact Connector in the Control Panel
Application has a blank User ID/Password property value, then the User Logon dialog is displayed for
each Impact Connector prior to connection.
• Sequential Device Connection with a Single Logon Dialog: The designer must create a primary
Impact Connector that attempts connection before the other connectors. The UserID\Password prop-
erty from the secondary Impact Connector(s) can be linked to the primary Impact Connector’s Use-
rID\Password property. This causes only one User Logon prompt to be displayed for the "main"
Impact Connector and the other connectors will then receive the logon information via the property
links.
