Abstract: A computer system with various component modules with each of the modules interconnected with a single midplane board, thereby eliminating the need for ribbon cables to interconnect between the modules. One of the modules includes an embedded controller and associated data bus. An in-line connector is coupled in the data bus which receives either a jumper connector or interconnect connector. The interconnect connector intercepts the data bus from the embedded controller and transfers connection to a user added controller. The interconnect connector can operate in two modes, a single mode and a differential mode. The interconnect connector includes logic circuitry that determines the type of controller connected and places the interconnect connector in the appropriate mode. If the logic circuitry detects that a single-ended controller is connected to the interconnect connector, a quick switch, which is connected to one wire of the data bus, is closed, thereby grounding the one wire.
