Abstract : The Intelligence Surveillance and Reconnaissance Technology Integration Branch of the US Army Research Laboratory routinely develops custom embedded hardware for use in distributed command and control systems. This report covers the design details of a smartphone-controlled wired RS-485 network. The Android-based smartphone or tablet is used in conjunction with a USB to serial bridge to operate as the bus master in the system. The Android device operates in USB Host mode and communicates to the RS-485 bus as if a single peripheral on the USB bus.
