Introduction
Ensuring that your LK202-25 display’s exactly what you want it to can be the difference between a
projects success and failure. This is why we incorporate features such as Data Lock into the LK202-25 With
this new feature you now are in control over of how and when settings will be changed so there is no need
to worry about the module acting exactly like you expected it to because all the settings may be locked and
remembered for the next power up.

0: Do not remember, 1: Remember
Description
This command allows you to switch the remember function on and off.
To use the remember function, set remember to on, then set all of the
settings that you wish to save, settings that are listed as ’Remember:
Yes’ support being saved into the non-volatile memory. After you have
set all of the commands that you wish to save, you may then cycle the
power and check the display settings to ensure that all the settings have
been saved. If you wish to use remember again after cycling the power,
you must set it to on again.
NOTES
•
Writing to non-volatile memory is time consuming and slows down the operation of
the display.
•
Non-volatile memory has a ‘write limit’ and may only be changed approximately
100,000 times.
