global unlock – Global unlock is a feature that designates a specific input on the PXL-250 controller to be used to
automatically unlock all doors in the access control network.
host computer – The host computer is the computer running the Doors software and communicating with the
access control network.
ingress– Ingress is a term for entering a secured area. (See egress.)
input – An input is a set of points on a controller that is able to receive a signal indicating when an
external device changes state. For example, the door switch input on the controller is attached to a
switch on the door. Using the switch, the input is able to keep track of when the door is opened or
closed; when the switch is open, the door is open and when the switch is closed, the door is closed.
log on – Log on is the process by which an operator enters a name and a password that identifies that
operator to the Doors program. This identification is used by the program to control which
commands an operator is authorized to perform and track which operations the operator does
perform.
loopback plug – A loopback plug is a small, serial port connector used by the COMTEST program to verify basic
operation of the host computer’s COM port. It is used to route signals sent out via the COM port
transmit line back to the COM port receive line. Before running the COMTEST, the loopback plug
is connected to the COM port designated for use by the Doors software. When the test is
complete, the loopback plug is removed and the communication line is connected.
menu bar – A menu bar is a horizontal field near the top of a program window of a program operating in a
Windows operating system that allows a program operator to select program commands and
options.
message timer – The EntraGuard message timer determines the length of time a banner message is displayed on the
EntraGuard LCD before changing to the next banner message.
modem – A modem is a communication device that converts computer serial data to a format that can be
transmitted and received via telephone.
monitor – A monitor is a window within the Doors software that tracks events that are occurring on the
access control system as they happen.
multiple sites – See site.
off-line – The access control network is off-line when it is not actively communicating with the host
computer.
online – The access control network is online when it is actively communicating with the host computer.
online help – Online help is a mini-program within the Doors software that provides basic descriptions and
instructions for the Doors software. Online help can be run at the same time as the Doors program,
side-by-side, making it easier for an operator to receive basic information regarding a program
command or operation.
operator – An operator is an individual who has been granted the authority to perform certain Doors program
managerial operations.
