P-871H Series User's Guide Appendix C ASCII Characters This appendix tells you about ASCII (American Standard Code for Information Interchange) characters. ASCII Code Computers use ASCII code to represent binary (0 or 1) as letters and other characters. The ASCII code is a list that contains all the letters in the alphabet plus other additional characters. In this code the same order number always represents each character. For example, in ASCII code the capital letter A is always represented by the order number 65, which is easily represented using 0's and 1's in binary (1000001). The standard ASCII code defines 128 character codes (from 0 to 127), of which, the first 32 are control codes (non-printable), and the other 96 are representable (printable) characters: *This panel is organized in hexadecimal: row numbers represent the first digit and the column numbers represent the second digit. For example, the A character is located at the 4th row and the 1st column, which is represented in hexadecimal as 0x41 (65). Appendix C 95
