Drop Hold Percentage: The percentage of the total drop retained by the Operator. Calculated as
(Combined Drop - [Fills + Attendant Paid]) / Combined Drop.
DUART: (Dual Universal Asynchronous Receiver Transmitter) A communication IC that can
interface between a microprocessor and a serial channel. See also UART.
EEPROM: (Electronically Erasable Programmable Read-Only Memory) A memory IC where
contents can be erased with electric signals.
EIA: (Electronics Industry Association [approved board]) An SDS ® electronic circuit board in
the CIU/SIU that interfaces the RS-232 signal lines with the SDS ® computer. Each EIA board
supports four terminals.
Electromechanical Meters: Lifetime counters within the machine that record accounting informa-
tion. Commonly used meters are total in, total out, and combined drop. Usage varies with
Market Code and configuration. The electromechanical meters are an independent record of
the same information stored in bookkeeping meters.
Electronic Meters: See Bookkeeping Meters.
Electronic Signature: Individual identification, such as the magnetically encoded number on SDS
®
Player or Employee cards.
Employee Card: An SDS ® magnetic stripe card encoded with the Employee’s identification
number, permission level, and expiration.
End of Game Signal: A serial or discrete output from the MPU indicating that a game has
completed.
Environmental Requirements: Physical space, heat load, and power requirements of the
machine.
EPI: (Enhanced Player Interface) An enhanced SDS
®
DMK with a flexible modular design.
Enhancements include a card reader with a lighted bezel and a two-line vacuum fluorescent
display. It has all the standard DMK functions plus hot key options accessed through the
keypad.
EPI Fill Request: See DMK/EPI Fill Request.
EPROM: (Erasable Programmable Read-Only Memory) An electrically programmed memory
IC erased by exposure to ultraviolet light. It provides a nonvolatile medium for program instruc-
tions. Game programs and video graphics are stored in EPROMs.
Error Messages: See Exception Codes.
Escalator: The part of the slant or bar hopper that carries coins up to the coin bucket assembly.
E 2 ) (E Squared) See EEPROM.
Even Handpay: Machine option, when enabled, allows a partial payment upon a jackpot lockup
that is independent from the option coin hopper pay amount. The hopper pays enough addi-
tional coins so that the Attendant Pay amount is an “even” amount.
Event Log: Listing of SDS ® metered events that have been recorded by the machine.
