Chapter 5 Windows CE .NET Operating System
Dynamic RAM
The RAM memory is split into two segments: Storage and Program
memory. The System application in the Control Panel has a slider
control that determines the allocation mix between Storage and
Program memory.
The Storage memory segment is a virtual RAM disk known as the
Object Store. It provides specialized storage for the Windows CE .NET
Registry, the file system, and system databases. The RAM-based
Storage memory segment is not persistent as in HPC devices, so all
files stored here must be recreated at every startup.
The Program memory segment provides traditional computer
RAM-like functions for holding application code, heaps, stacks, and
data at runtime. The PanelView Plus CE terminal loads the Windows
CE .NET operating system and any auto-start applications from flash
memory into the Program memory at powerup.
External CompactFlash Cards
External CompactFlash cards are available for the PanelView Plus CE
terminal to increase the space for storing files. When a CompactFlash
card is installed in the card slot of the PanelView Plus CE terminal, a
StorageCard2 icon is displayed under My Computer, and files on the
memory card can be manipulated by using the Windows Explorer
program.
The card slot on the PanelView Plus CE terminal supports Type 1
CompactFlash cards. The cards (2711P-RCx) are available in different
sizes.
For details on how to install/remove cards from the card slot, refer to
Chapter 6.
USB Mass Storage Devices
USB devices that comply with the USB Mass Storage Class
Specification, version 1.0, are supported to enable a wide variety of
USB-based storage devices such as hard drives, floppy disks, CD-ROM
drives and ATA flash readers. Up to 10 devices are supported,
concurrently. DVD drives are not supported.
