Block Category: Real-Time
The Serial Write block writes data to the Serial bus. The enable input pin must have a value of 1 for the block to send data. The values presented on the data pins are sent to the serial port. If you connect a string type (that is, a quoted constant in the const block), the Serial Write block will transmit all characters in the string for each enable pulse; otherwise, a single byte is sent.
Unit: Specifies the serial communication port to which data is written.
