CR 1212 26
67 x 12 inches = 804 … is the desired X axis resolution
86 x 12 inches = 1032 … is the desired Y axis resolution
2. Convert the desired axis resolution to a hexadecimal number.
Example: 804 decimal = 324 hexadecimal
1032 decimal = 408 hexadecimal
If the number is less from four digits, pack the left side with zeros. For example, 324
becomes 0324; 408 becomes 0408.
Separate the hexadecimal number into two 2-digit parts, the most significant byte
(high byte) and the least significant byte (low byte).
Example:
0324 = 03 high byte 24 low byte
0408 = 04 high byte 08 low byte
3. You’re now ready to send the Definable Resolution command sequence to the
tablet. In the example of 800 by 1024 portrait screen, the command sequence is:
Command
X Low Byte X High Byte Y Low Byte Y High Byte
72 24 03 08 04
NOTE: To change the resolution of only one axis, send zeros as the other axis’s resolution.
4. To verify the new resolution settings, use the Send Configuration command.
