Abstract
Abstract A programmable connector module is equipped with a molded plastic base on which an IC chip is mounted. The plastic base is wired with programmable inputs which can be used to provide a logic 1 or a logic 0 to each input of the IC chip. Tabs or punch holes located on the plastic base can be broken to disconnect an input circuit from ground to allow a logic 1 to be programmed. Two inputs are used to program the configuration of the module and four inputs are used to program the address of the module. The programmable module can be positioned anywhere along a multiplex wire bus and is equipped with connectors for transmitting and receiving data to and from electrical loads along the bus.
