Probably the most convenient way to create single 1:1 patch connections in Pathfinder is doing so via drag and drop.
It is also possible to drag an existing connection from one port to another to quickly change it, for example in case of a faulty port.
In order to create a new 1:1 patch connection, simply drag and drop the source port on top of the destination port.
If you want to simply move an existing patch connection to a different port on either side, you can drag a patched port onto an idle port and confirm the change.
Once you have selected the two ports, you can then select the cable definition (1). A cable definition is suggested by Pathfinder based on the source and destination port types.
If there is a matching naming rule, a name will automatically be assigned. You can edit the name and tick the boxes to ensure the name is unique and immediately print a barcode.
Below the connection will be displayed (2) so you can ensure the selection is correct.
Finally click on Finish to create the new cable as specified.
