C.2 Contrast Adjustments for All Boards
Starting in 2005, LCD/keypad modules were factory-configured to optimize their contrast
based on the voltage of the system they would be used in. Be sure to select a KDU3V
LCD/keypad module for use with the Prototyping Board for the RCM3365/RCM3375 —
these modules operate at 3.3 V. You may adjust the contrast using the potentiometer at R2
as shown in Figure C-3. LCD/keypad modules configured for 5 V may be used with the
3.3 V Prototyping Board, but the backlight will be dim.
You can set the contrast on the LCD display of pre-2005 LCD/keypad modules by adjust-
ing the potentiometer at R2 or by setting the voltage for 3.3 V by connecting the jumper
across pins 3–4 on header J5 as shown in Figure C-3. Only one of these two options is
available on these LCD/keypad modules.
User’s Manual
NOTE: Older LCD/keypad modules that do not have a header at J5 or a contrast adjust-
ment potentiometer at R2 are limited to operate only at 5 V, and will not work with the
Prototyping Board for the RCM3365/RCM3375. The older LCD/keypad modules are
no longer being sold.
