Sensor interface for selectively providing analog and digital output

摘要

An interface device system includes a first transceiver, a second transceiver, and a controller for receiving an input signal and detecting whether a predetermined type of network connection exists. The controller selectively transmits a first signal or a second signal that corresponds to the input signal. The controller transmits the first signal over the first transceiver in response to absence of the predetermined type of network connection. The controller transmits the second signal over a second transceiver in response to existence of the predetermined type of network connection.
