Advanced Tab
The Advanced tab allows you to do the following:
• Uninstall – Uninstall the drivers.
• Enable Event Logging – Place event messages in system event log.
• COM Port Assignment – Configure how COM ports will be assigned.
The driver supports COM port number assignment in two ways:
1. 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.
2. 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 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.
After changing this setting, you will need to reboot before the change takes effect.
