2.5 Manual Override

The Manual Override is provided to allow the GLC24064 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

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 Jumper on the Manual Override pins.

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.

2.6 File System Lock Jumper

The File System Lock Jumper allows you to lock the ﬁle system on the GLC24064 so that no fonts or

bitmaps can be either written or deleted from the on board memory. This feature is useful in order to protect

data integrity of production units, if protection of other settings is required see Chapter 12 Data Security.
