Messages will be sent and received using the platform above. The transmitter and receiver will be powered by an external regulated power supply that can provide a voltage from 0V to 20V and measure the power consumption to the nearest mW. Teams will specify the output voltage of the each power supply. The transmitter and receiver will communicate with transmit and receive computers using a 3-wire RS-232 serial connection operating at a standard 3.3V, 9600 baud, 8 data bits, 1 stop bit, no parity, no hardware flow control. To ensure that your design properly interfaces with the test platform, it should be meet the following specifications.
