-The %%Pmod MAXSONAR%% communicates with the host board via the [[pmod:communication_protocols:uart|UART protocol]], analog output, and [[reference:pwm|PWM]] timing. The module requires 250 milliseconds to power up and then will perform a self-calibration if the Receive Data (RX) pin is left at floating or logic level high voltage. The calibration will take 49 ms, and after an additional 100 ms of waiting time, the module will be able to take measurement readings every 49 milliseconds. +The %%Pmod MAXSONAR%% communicates with the host board via the [[pmod:communication_protocols:uart|UART protocol]], analog output, and [[:pwm|PWM]] timing.

 The %%UART%% protocol is configured with a baud rate of 9600, 8 bits, no parity, and a single stop bit. When the RX pin is left floating or held at a logic level high voltage, 5 bytes will be sent out over the Transfer Data (TX) pin beginning with the capital ASCII character 'R', three %%ASCII%% digits representing the detected distance, and a carriage return character (%%ASCII%% character 13). The %%UART%% protocol is configured with a baud rate of 9600, 8 bits, no parity, and a single stop bit.
