The Torbal USB adapter provides a bidirectional bridge between a USB bus and the RS-232C serial port located on Torbal scales. Once installed, any Torbal scale can be connected to any PC via a USB cable. The adapter is particularly useful when connecting a Torbal precision scale or balance to a PC that lacks a standard RS232 port. The adapter is furnished with a pre-connected crossover link that assures compatibility with Torbal scales, as well as a USB cable and a CD that includes all necessary drivers.
