9.4 The USB Interface
The Ohaus USB Interface is a unique solution to the problem of connecting a balance to a computer using a Universal
Serial Bus (USB). USB devices are categorized into classes such as disk drives, digital cameras, printers, etc.
Balances do not have a commonly used class so the Ohaus USB interface uses a generic interface based on the
RS232 serial standard.
Data sent from the balance to a computer is in USB format. The USB data is directed to a virtual port. This port then
appears as an RS232 port to the application program.
