Charging
The process a battery is subjected to return it to full output capacity.
The process is accomplished by passing an electrical current
through the battery plates and electrolyte to restore the chemicals to
their original state.
Continuity
The condition of a circuit when it makes a connection between two
points.
CPU
Central Processing Unit. The “brain” of a computer, the CPU is
where data manipulation actually takes place.
Current
The rate electrons flowing over a period of time. This is usually
expressed in amperes
Cycling
The repeated charge and discharge of batteries
DB-9
A common type of electrical connector named for the characteristic
D-shaped metal shield that surrounds the parallel rows of pins or
sockets. A DB-9 connector has nine pins total, arranged in two
rows.
DCE
Data Communications Equipment. The serial communications host
(typically a PC ).
Deep Discharge
To expend 80% or more of a battery’s capacity.
DHCP
Dynamic Host Configuration Protocol. A standardized network
protocol used on Internet Protocol (IP) networks for dynamically
distributing network configuration parameters, such as IP addresses
for interfaces and services. With DHCP, computers request IP
addresses and networking parameters automatically from a DHCP
server, reducing the need for a network administrator or a user to
configure these settings manually.
Direct Current
Electrons flowing in a single direction. Abbreviated as DC.
DNS
Domain Name System. A system that controls a domain name's
website and email settings. When visitors go to a domain name, its
DNS settings control which entity's server it reaches out to.
DTE
Data Terminal Equipment. The serial communications device with
which the DCE communicates.
Electricity
The flow of electrons through a circuit or device.
E-Net
See Ethernet
Ethernet
A system for connecting a number of computer systems to form a
local area network or a means of connecting a computer to a modem
for connection to the Internet.
ETM
Ethernet Manager.
FIFO
First In First Out
Form C
Dry contact relay configuration. The MP2000 uses 1 Form-C dry
contact indicators.
FTP
File Transfer Protocol.
