Memory and File Systems

The default memory space for the DA-681-CE is 512 MB. Approximately 233 MB of this space

will be used for the operating system and user applications. If you would like to use the rest of the

space, you will need to adjust the system memory manually. Refer to Adjusting the System

Memory section for details on how to do this.

The DA-681-CE’s internal file system controls access to the compact flash card and a RAM disk.

The file system provides persistent storage for applications and related data, even when the main

power supply is lost. When the system resets, all files stored in RAM disk will be lost.

The root directory is a ROM file system, which differs from the system used by Moxa’s

UC-7400-CE embedded computer. The DA-681-CE root file system is a persistent file system.

There is no any RAM file system stored in DA-681-CE.

The internal file system is uses a FAT (File Allocation Table). This means that the internal file

system of the computer provides the ability to mount external FAT file systems.

The additional file systems on USB and CompactFlash storage devices are placed at the root of the

internal file system. If you intend to use these devices to port data between your PC and the

DA-681-CE computer, please format them as the FAT file system on your PC.

Hive-Based Registry

The registry for the DA-681-CE is a hive-based registry, in contrast to a RAM-based registry. The

hive-based registry stores registry data inside files, or hives, which can be kept in a file system,

which removes the need for performing backup and restore on power off.
