2.5 Manual Override
Manual Override is provided to allow the GLK240128-25 to be reset to factory defaults. This can be
particularly helpful if the display module has been set to an unknown baud rate or I 2 C Slave Address and
you are no longer able to communicate with it. If you wish to return the module to its default settings you
must:
1. Power off the display module.
2. Place a jump between Row 5 and Column 1.
3. Power up the display module.
4. The display module is now set to its default values listed below in
table 1 .
5. Edit and save settings.
