Appendix G Understanding Hexadecimal
The table and explanation shown below are intended for those who are familiar with the binary
numbering system but wish to have a review of the hexadecimal numbering system. Knowing how
to convert from binary notation to hexadecimal and decimal notations will help you to interpret the
Printer Port LED Connector.
As shown in the table below, hexadecimal and decimal values are identical for numbers 1 through 9.
Numbers 10 through 15 however are represented by the letters “A” through “F” in the hexadecimal
numbering system.
Table B-1 Hexadecimal Conversion Chart
The eight-digit binary notation shown below is representative of how the digits are separated into
four bits, with each group of four bits being converted to a hexadecimal value. The four bits on the
left consist of a binary 1110. Using Table A-1, this would stand for the hexadecimal value of “E.”
The second group of four bits consists of a binary 0011. This would symbolize the hexadecimal
value of “3.”
