USB DIRECTORS RS-232
2.Allows you to configure how COM ports will be assigned.
The driver supports COM-port number assignment in two ways:
1.Assigning COM ports based on units’ serial numbers. This is the default setting. In this mode, the driver uses the serial number of each unit to uniquely identify it, and the COM-port assignments for a given unit are based on its serial number. No matter which physical USB port a unit is plugged into, it will maintain its assigned COM- port numbers.
2.Assigning COM ports based on physical USB port. In this mode, the driver identifies a unit based on the physical USB port it is plugged into. This effectively assigns COM-port numbers to physical USB ports. No matter which unit is plugged into a given USB port, it will use the COM-port numbers assigned to that USB port. This permits one unit to be replaced with another, 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.
