ABSTRACT:
A generic serial interface includes any one of multiple transition cables having a first connector conforming to one of several different serial interface standards. A second generic connector is connected to a second end of the transition cables. A configurable interface circuit is coupled to the generic connector and is automatically reconfigured according to the physical interface type associated with the transition cable. The interface circuit includes a termination resistor array that can connect different termination resistor values to the same generic signals on the generic connector according to the interface type. The termination resistor array in combination with a unique designation of generic signals allow a single interface to operate with many different serial interface standards both in DCE and DTE modes while requiring substantially fewer connector pins and simpler interface circuitry than existing generic interfaces.
