APPENDIX B
ASCII Table
An ASCII table for the Omni 37xx display is presented as Figure 25 below. The
table is formatted for quick reference, as follows:
• The letters and numbers in the column to the left of the table and in the row
above the table are, when combined, the hexadecimal value of an ASCII
character located in the corresponding row and column coordinate.
• The numbers shown in white on a black background within the table itself are
the decimal value of the ASCII character in that table cell.
• The large character located in the middle of each cell is the ASCII character.
For example, to determine the hexadecimal value of the plus (+) sign:
1 Locate the plus sign ASCII character in the table (decimal 43).
2 From this position, follow the row to the left and view the hexadecimal value in
the column outside the table. This value (2) is the first character of the ASCII
character’s hexadecimal value.
3 Now, from the plus sign, follow the column to the top of the table and view the
hexadecimal value in the row above the table. This value (B) is the second
part of the hexadecimal value.
4 The hexadecimal value for the ASCII plus sign (+) is therefore 2Bh.
