2.5 Filesystem Lock Jumper
The
Filesystem Lock Jumper
allows you to lock the ?lesystem on the GLK12232-25 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
Section 13.
To lock the ?lesystem, solder a zero ohm resistor or use a sold
er jumper on the
Filesystem Lock Jumper
pictured in
?gure 16
