All CV values except for 2 digit and 4 digit addresses can be displayed as either decimal or hexadecimal numbers by the DT400.
When you are using the L Throttle knob to browse through CVs 002 through 255, you will use the R Throttle knob to set the CV value you want to program.
By default, the DT400 displays the CV values as decimal numbers 000-255 (nnn).
To view the numbers as hexadecimal simply press the R throttle knob and you will see the CV value change to the hex equivalent of the decimal. Hex numbers are displayed as xnn. For example the decimal value of 006=the hex value x06. The decimal value 011= x0B.
The ability to toggle between decimal and hex effectively gives you an instant conversion table.
