Figure 1: DS9097U

The DS9097U is the critical piece of hardware which provides a gateway between a PC and a 1-wire network. The DS9097U is fitted with a 9-way serial port socket (female connector) at one end, enabling it to be plugged into an RS-232 serial port on a PC. On the other end of the DS9097U, there is an RJ-11 socket. Into this RJ-11 socket one can fit an RJ-11 plug connected to a 1-wire network.
