COM Port Assignment
- Configure how COM ports will be assigned.
l
Assign COM ports based on converter serial number.
This is the default setting. In this mode, the driver uses the serial number of each converter
to uniquely identify it, and the COM port assignments for a given converter are based on its
serial number. No matter which physical USB port a converter is plugged into, it will
maintain its assigned COM port numbers.
l
Assign COM ports based on physical USB port.
In this mode, the driver identifies a converter based on the physical USB port it is plugged
into. This effectively assigns COM port numbers to physical USB ports. No matter which
converter is plugged into a given USB port, it will use 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 will receive 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 identified not by their serial number, but by a 2-7
digit number that identifies which USB port it is plugged into.
When the COM ports are assigned, click
OK
. You must reboot the computer before the change
takes effect.
