Overview of Backshells
You can add one backshell to a connector in Capital Logic Designer. You can specify terminations on the backshell to which wires or shield conductors can connect.
When you share the connector, you also automatically share the backshell. However, the backshell is only shared across instances of that connector. You cannot share a backshell across connectors. There is no specific functionality for adding a shared instance of a backshell termination because you can add multiple instances of a termination and this implies that the termination is shared.
Procedure
A typical workflow for using a backshell is as follows:
Create a backshell symbol in Capital Symbol Designer. The symbol is used in Capital Logic Designer to represent a backshell termination. For example: If you draw a backshell symbol as follows: When you add a backshell termination with the name BS1 to a conductor and use that symbol, it will look like this: The symbol relates to one backshell termination so you can add only one pin to it. If you add a library part to an instance of a backshell, the library part can have an infinite number of backshell termination connections. If you add a pin, the pin is used as the insertion point marker when the symbol is added to a Capital Logic Designer diagram. If you do not add a pin to the symbol, the normal insertion point marker is used. See also Creating a New Symbol in the Capital Symbol Designer User Guide.
Add a backshell to a connector in Capital Logic Designer and define backshell terminations on the connector. See also Adding a Backshell and Backshell Termination to a Connector.
Associate a library part description with the backshell on the diagram. See also Object Attributes and Properties. The library part description must have been defined in Capital Component Manager first. See the Capital Component Manager User Guide to define library parts.
