DC
Abbreviation of Direct Current. Alternative writing style: “d.c.“

AC
DC/DC converter
Component which converts a DC voltage into another DC voltage.
Normally, DC/DC converters also provide for voltage separation. DC/DC
converters are, for example, used in the fieldbus modules FI 830F,
FI 820F and FI 810F.
DCF77 radio clock
The PTB (Physikalisch-Technische Bundesanstalt = Federal German
Institute of Physics and Technology) in Braunschweig/Germany transmits
a standard time signal from its long-wave transmitter station near
Frankfurt/Main. This signal can be received by a DCF77 clock and is then
used for synchronizing the times throughout the Freelance 2000 system.
The DCF77 radio clock is connected to the AC 800F diagnostic interface.

GPS
Debug module AM 802F
Debugging module for service purposes, only.
Diagnostic cable (RS232C)
Diagnostic cable TK 890F (10 m) or TK 891F (5 m) serves for connecting
a diagnostic PC or laptop to the AC 800F.
Diagnostic interface
RS232 interface of the AC 800F; for status and error message output
during diagnosis. The diagnostic interface is also used for connecting a
DCF77 radio clock.

DigiLink *
)
RS485 interface of the AC 800F for connecting subsystems like balances
and bar code readers via Modbus protocol. Two of these interfaces are
available on the fieldbus module FI 820F.

Operator station
Dummy panel AM 895F
Always cover unused slots with dummy panels (caps) to protect the
electronics from being touched and provide for good EMI/RIF shielding
and RFI suppression capabilities of the AC 800F.
- E -
EDC unit
Acronym for Error Detection Correction.
A check sum is assigned to every 32-bit value in the main memory to
improve the data integrity.
EEPROM
Acronym for Electrically Erasable and Programmable Read only Memory.
The EEPROM is an advanced EPROM. While EPROMS can only be
erased with an ultraviolet ray lamp, it is possible to erase built-in
EEPROMS. EEPROM are used on the CPU board and on the module
boards for storing manufacturing information (e.g. serial No. or version
No.)

EPROM, ROM
EMC
Electromagnetic Compatibility.
Represents the EMI/RFI shielding capability as well as the degree of RFI
suppression of a unit.
EMI
Electromagnetic Interference
EMI/RFI shielding
Degree of shielding against external EMI and RFI.
