USB Keyboard FN 1 Substitution
This option applies only to the USB HID Keyboard Emulation device. When enabled, this allows replacement of 
any FN 1 characters in an EAN 128 bar code with a Key Category and value chosen by the user (see FN1 
Substitution Values on page 5-50 to set the Key Category and Key Value).
USB Static CDC
When disabled, each device connected consumes another COM port (first device = COM1, 
second device = COM2, third device = COM3, etc.)
When enabled, each device connects to the same COM port.
