EEPROM
Electrically Erasable
Programmable Read Only
Memory. The portion of the
monitor’s memory which holds
sysgen information and hardware
configurations.
EMI
Electromagnetic Interference
generated by repetitive signals
such as microprocessor clocks
that can interfere with other
devices or two-way radio
communications.
EPP
Enhanced Parallel Port
ESD
Electrostatic Discharge. High
voltage potentials carried on the
body that are generated by
walking across a carpeted floor or
caused by low humidity
environments, which can be
discharged into an electronic
device, damaging it.
Ethernet
The LAN technology that uses
CSMA/CD physical access
method and 10/100 Mbps digital
transmission. The forerunner of
the IEEE802.3 CSMA/CD
standard.
Flash ROM
A type of EEPROM that can be
erased and reprogrammed in
blocks instead of one byte at a
time.
Ferrite
RF (radio frequency) glossy
material used in EMI suppression.
FPGA
Field-Programmable Gate Array.
Flexport System Interface
Spacelabs Healthcare device that
communicates via RS232 with
other manufacturer’s equipment.
FRU
Field-replaceable unit
FTP
File Transfer Protocol. The
protocol for exchanging files over
the Internet.
GDS
Global Data System
GPCM
General purpose chip select
machine, used as an interface
between the processor and
memory
GPIO
General Purpose Input Output
High level output
Analog signals supplied through a
separate connector for use with
external equipment.
HRESET
Hardware reset
IC
Integrated circuit
I/O
Input/Output port or device
IEEE
A U.S. professional organization
active in the creation, promotion,
and support of communications
specifications and standards.
IP Address
Internet Protocol Addresses used
in TCP/IP. Identifies packet origin/
destination.
IRTS
Infrared Touchscreen. One of the
user interfaces to the Spacelabs
Healthcare monitoring system.
ISA
Industry Standard Architecture. A
standard bus (computer
interconnection) architecture
JTAG port
A test access port used for testing
printed circuit boards
Kernel
The center of a computer
operating system, which provides
basic services for all other parts of
the operating system
LAN
Local Area Network. A network
system that provides a relatively
small area with high speed data
transmission at a low error rate.
LCD
Liquid crystal display
LED
Light emitting diode
Light transmittance
Measure of light levels as
measured at the face of the CRT.
Lithium
Material used to construct a high
energy battery for use in CMOS
backed circuits.
MAC address
Media Access Control address. A
unique identifier attached to
networking equipment.
Mbit
Measurement used for RAM
devices. Example: a 4 Mbit device
will contain 4 megabits of data.
MDC
Management Data Clock
