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 KDU5V
LCD/keypad module for use with the RCM3000/3100/3200 Prototyping Board — these
modules operate at 5 V. You may adjust the contrast using the potentiometer at R2 as
shown in Figure C-3. LCD/keypad modules configured for 3.3 V should not be used with
the 5 V RCM3000/3100/3200 Prototyping Board because the higher voltage will reduce
the backlight service life dramatically.
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 5 V by removing the jumper across
pins 1–2 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 work with the
Prototyping Board. The older LCD/keypad modules are no longer being sold.
