The Off Sheet Connector dialog.

Summary

This dialog allows the designer to specify the properties of an Off Sheet Connector object. An off sheet connector is an electrical design primitive. Off sheet connectors are used to connect nets across multiple schematic sheets that are descended from the same parent sheet symbol.

For information on how a placed off sheet connector object can be modified graphically, directly in the workspace, see Graphical Editing.

Access

The Off Sheet Connector dialog can be accessed during placement by pressing the Tab key.

After placement, the dialog can be accessed in one of the following ways:

  • Double-clicking on the placed off sheet connector object.
  • Placing the cursor over the off sheet connector object, right-clicking and choosing Properties from the context menu.

Options/Controls

  • Location X/Y - the current X (horizontal) and Y (vertical) coordinates for the connection point of the connector (its electical hotspot). Edit these values to change the position of the connector in the horizontal and/or vertical planes respectively.
  • Color - click the color sample to change the color used for the connector, including its text, using the standard Choose Color dialog.
  • Orientation - specify the orientation of the connector, counter-clockwise in relation to the horizontal. Options available are: 0 degrees, 90 degrees, 180 degrees, 270 degrees.
  • Style - use this field to specify the direction of the connector's arrow, pointing either Left or Right.

Properties

  • Net - use this field to specify the net name for the connector. Off sheet connectors with the same name will be electrically connected across sheets descending from the same parent sheet symbol. Connectivity is not made between sheets descending from different sheet symbols, even if they contain off sheet connectors with matching net names.
To successfully connect a particular net across two or more sheets, the off sheet connectors on each sheet must be assigned to the same net.
  • Locked - enable this option to protect the connector from being edited graphically.
An object that has its Locked property enabled cannot be selected or graphically edited. Double click on the locked object directly and disable the Locked property, to graphically edit the object.

Notes

  1. It is important to remember that although there are times when an off sheet connector and a sub-divided sheet symbol can be useful, they do have limitations. They will not properly form automatic component classes and these need to be recreated manually in the PCB if you choose to use them.
  2. Port Cross-References cannot be applied to off sheet connectors, therefore Ports should be used where possible.
