ABSTRACT:
An electronic embedded command module to control devices located in spacecraft includes a serial command decoder to decode serial digital input commands and control a switch matrix, a command buffer to provide a compatible serial digital input command to the serial command decoder, a standby circuit to control power to the serial command decoder, and a switch matrix to provide output commands. A method for controlling devices located in a spacecraft in response to a serial digital command signal. The method includes receiving the serial digital command signal, changing from an inactive state to an active state, processing the command signal while maintaining the active state, generating an output signal, and returning to the inactive state. This electronic command module controls its own power status and consumes negligible current when in the inactive state. This electronic command module reduces wire harness and command module weight and lowers system design, wire harness and command module cost.
