E5805A USB/RS232 Interface
In this mode, the driver identifies a converter based on the physical USB port where it is connected. This effectively assigns COM port numbers to physical USB ports. No matter which converter is plugged into a given USB port, it uses the COM port numbers assigned to that USB port. This permits a converter to be replaced with a new unit, and, although the new unit has a different serial number, it receives the same COM port assignments as the old unit because they were both plugged into the same USB port.
When using this mode, converters are not identified by their serial number, but by a 2- 7 digit number that identifies the USB port it is plugged into.
After changing this setting, you need to reboot before the change takes effect.
