Definition
Override an alarm on a door contact that detects an open state on the door.
A digital input device monitors the door state. If the door opens with a valid read (or exit device),
the input device (a door contact) detects a state change but does not report the change until a
shunt time elapses. The shunt time allows the badgeholder enough time to get through the door.
See Door Forced Open and Door Open Too Long.
To override a door sensor for a longer time, enter a keypad override code (a microcontrollerdependent
code set on the Micros screen).
To stop running the application and the operating system.
SSL (Secure Sockets Layer) is a commonly-used protocol for managing the security of a message
transmission on the Internet. SSL uses a program layer located between the Internet's Hypertext
Transfer Protocol (HTTP) and Transport Control Protocol (TCP) layers.
Network nodes that are related by the same IP address range. Example: computers with an
address beginning with 192.168.1.x are in the same subnet.
A 32-bit address used in conjunction with an IP address to segment network traffic; used to restrict
transmissions to certain subnets.
The current condition of something, such as a badge or a micro. The Status monitor is used for
viewing a micro’s current database to verify configuration and scheduling.
A language that can be used in Picture Perfect. All languages other than English and French must
be translated and made available before they can be used.
A message from the host that synchronizes the micro’s clock.
A full-function operator; an operator permission without any function restrictions.
Communications protocol used to connect to a variety of different types of hosts on both private
networks and carrier networks such as the Internet.
Transaction Processing System; the program that communicates with microcontrollers.
Microcontroller activity.
In UNIX-based operating systems, any terminal at all; sometimes used to refer to the particular
terminal controlling a given job. Also the name of a UNIX command which outputs the name of the
current controlling terminal.
A communications protocol for the Internet network layer, transport layer, and session layer, which
makes it possible to send a datagram transmissions from one computer to a recipient computer.
UNIX A multi-user, multitasking network operating system developed at Bell Labs in the early 1970s.
Linux is based on, and is highly compatible with, UNIX.
Unlock Time
Upstream
Workstation
The length of time a door latch is to remain unlocked after a valid badge read (or after an exit
button activates). This time allows the badgeholder to open and pass through the door.
A relative position on a communication line originating at a host computer. Example: the second
micro on a line is “upstream” from the third micro, because the second micro is relatively closer to
the host.
An X Terminal that displays the forms that the operator uses to interact with the system; connected
to the host computer using an Ethernet LAN (Local Area Network). See LAN.
