enroll – Enrolling is the process of activating a card for use by a cardholder in the access control
network. A card must be entered into the access control network and then assigned to a
cardholder.
event – An event is an occurrance at a controller (such as unlocking a door, requesting to exit, forcing
a door open) that generates a message stored by the controller.
firmware – Firmware is a set of operating instructions for a controller, stored on a ROM on the controller.
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.
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.
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.
offline – The access control network is offline 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.
on-line help – On-line help is a mini-program within the Doors software that provides basic descriptions and
instructions for the Doors software. On-line 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.
output – An output is a relay on a controller that is toggled, to open or close an external circuit based
on either commands programmed into the controller or based on the state of an input. For
example, if a door is forced open, an output relay is programmed to sound an alarm.
