Juniper Allegro CE Owner's Manual page 102

The Memory tab allows you to adjust the allocation of RAM between
program memory and storage memory.
The majority of RAM should be allocated to program memory so the
applications have plenty of execution space. Define the amount of
usable RAM by subtracting the In Use figure from the Allocated figure.
The Device Name tab allows you to view or change the name of your
Allegro. In the Device name box, AllegroCE_##### (##### = serial
number) is entered automatically. This unique identification makes it
possible for individual Allegros to be identified by other computers,
and in situations where multiple Allegros are connected together.
