Operating Instructions, 09/2018, A5E41134132-AE
EMC directive
Directive concerning Electromagnetic Compatibility. Compliance is confirmed by the CE
symbol and the EC certificate of conformity.
Energy management
The energy management functions of a modern PC allow individual control over the current
consumption of vital computer components (e.g. of the monitor, hard disk and CPU), by
restricting their activity based on the current system or component load. Energy
management is of particular importance for mobile PCs.
Energy options
The energy options can be used to reduce energy consumption of the computer, while
keeping it ready for immediate use. This can be configured in Windows by selecting Settings
> Control Panel > Energy options.
Enhanced Write Filter (EWF)
Configurable write filter that allows you, for example, to boot Windows Embedded Standard
from write-protected media (such as CD-ROM), to write protect individual partitions and
adapt the performance of the file system to your needs (when using Compact Flash cards).
ESD Guideline
Directive for using electrostatic sensitive components.
Ethernet
Local network (bus structure) for text and data communication with a transfer rate of
10/100/1000 Mbps.
Execute Disable Capability
Hardware implementation that prevents mutual memory accesses by programs and
applications. It is only effective when all relevant system components, such as processors,
operating systems and applications are supported.
Extensible Firmware Interface (EFI)
Refers to the central interface between the firmware, the individual components of a
computer and the operating system. EFI is located logically beneath the operating system
and represents the successor to PC BIOS, focusing on 64-bit systems.
File Based Write Filter (FBWF)
Configurable write filter to protect individual files from write access.
