Abstract
A communication interface circuit in an aircraft entertainment system uses a single Universal Asynchronous Receiver and Transmitter (UART) for sending and receiving data to and from a number of devices. The UART is coupled to a number of transceivers each having a transmitter buffer and a receiver buffer. A circuit is used to enable and disable the receiver buffers. A masking element is coupled between the receiver buffers and the UART to mask off the data from the disabled receiver buffers allow only the data from the enabled receiver buffer to go to the UART. With this communication interface circuit, the amount of hardware is significantly reduced.
