A method of processing force signals from plural force platforms includes, in a computer, in an initialization process, receiving data distinguishing the plural platforms, monitoring force data signals from each of the plural platforms, and identifying each of the plural platforms to a force platform data process application by a sequence of received above-threshold force data signals. The method further includes, subsequent to the initialization process, processing subsequent force data signals according to the identification of each of the plural force platforms. The distinguishing data can include data retrieved from nonvolatile memory of each of the plural force platforms, such as a platform serial number, calibration data, and platform capacity. A force platform system includes one or more force platforms and force platform signal conditioning circuitry connected to the one or more force platforms. The signal conditioning circuitry may include a separate signal conditioner connected to each force platform.
