5.1 – Keyspan Serial Assistant

The Adapter Port Mapping Mode box allows you to change the behavior of how Keyspan COM port numbers are assigned when you connect the Keyspan adapter to a different USB port than the one it was originally connected to.

Dynamic assigns a COM port number (or numbers if your Keyspan adapter has multiple serial ports) to a particular Keyspan adapter. If you disconnect the Keyspan adapter and connect it to a different USB port, the COM port number of that Keyspan adapter will not change. This is the default setting and is recommended setting if you only have one Keyspan adapter.

Geographic assigns a COM port number (or numbers if your Keyspan adapter has multiple serial ports) to a particular USB port on your computer. If you disconnect the Keyspan adapter and connect it to a different USB port, the COM port number of that Keyspan adapter will change. This setting is recommended if you are using multiple Keyspan adapters and want the COM port numbers to remain the same.

The Delete All Keyspan USB 4-Port Serial Adapter Port Mappings button clears the Windows registry of all Keyspan USB 4-Port Serial Adapter COM port numbers and Keyspan USB information. This allows Windows to create new COM port assignments.

Note: This is an option for advanced users only.
