String Syntax in Interactive Control

You can enter strings as an ASCII character sequence, hex bytes, or special symbols.

ASCII character sequence: You must enclose the entire sequence in quotation marks.

Hex byte: You must use a backslash character and an x followed by the hex value. For example, hex 40 is represented by \x40.

Special symbols: Some instruments require special termination or end-of-string (EOS) characters that indicate to the device that a transmission has ended. The two most common EOS characters are \r and \n. \r represents a carriage return character and \n represents a linefeed character. You can use these special characters to insert the carriage return and linefeed characters into a string, as in "F3R5T1\r\n".
