Term Definition

Stands for "Musical Instrument Digital Interface." It is a connectivity standard that musicians use to hook together musical instruments (such as keyboards and synthesizers) and computer equipment. Using MIDI, a musician can easily create and edit digital music tracks. The MIDI system records the notes played, the length of the notes, the dynamics (volume alterations), the tempo, the instrument being played, and hundreds of other parameters, called control changes.


MIIP (Mobile Internet Interactive Playlist) is a guest interface to your show. Display owner records the show information on the MIIP server. MIIP formats a web page with this information for your guests to see. Guests interact with your show via the web browser on their phone. The display owner must have an announcement or sign to direct guests to visit miip.mobi to vote. Requirements are Light-O-Rama software be installed on your computer and have an internet connection.


Mini Director

The mDC-MP3(mini Director Card with MP3 Player) is designed to control a network of Light-O-Rama (LOR) light controllers while simultaneously playing MP3 music files. This is our smallest director unit. It does not have an internal clock for scheduling shows so an external timer is required. It can be triggered by external switches and/or motion detectors.


Small tree typically made from a tomato cage or floral easel.

Molex Connector

Molex connector is the vernacular term for a two-piece pin and socket interconnection, most frequently disk drive connectors. Pioneered by Molex Connector Company, the two-piece design became an early electronic standard. Molex developed and patented the first examples of this connector style in the late 1950s and early 1960s. First used in home appliances, other industries soon began designing it into their products from automobiles to vending machines to mini-computers.


A semiconductor device that contains diffused source and drain regions on either side of a P- or N-channel area. Also contains a gate insulated from the channel area by silicon-oxide. Operates in either the depletion or the enhancement mode.


A single meter combining the functions of an ammeter, a voltmeter, and an ohmmeter.


Usually, a non-dimmable bulb will be destroyed by a pwm controller such as LOR, Renard, Animated Lighting or any type of controller. If extreme care is taken with use and proper sequencing, they may survive being "blinked" on and off only at a 100% power setting. But, that's a big if.


(opto, optocoupler) A semiconductor device that allows signals to be transferred between circuits or systems, while keeping those circuits or systems electrically isolated from each other. In its simplest form, an optoisolator consists of an light-emitting diode (LED), IRED (infrared-emitting diode), or laser diode for signal transmission, and a photosensor for signal reception.


Printed Circuit Board. An electronics board that contains layers of circuitry that connect the various components of a system. A PCB can be mass manufactured or can be "home etched," where a hobbyist transfers the design of the PCB to a copper-clad board, uses caustic chemicals to etch away the areas not needed and then drills the holes him or herself.

PIR Motion Detector

A Passive Infrared sensor (PIR sensor) is an electronic device that measures infrared (IR) light radiating from objects in its field of view. PIR sensors are often used in the construction of PIR-based motion detectors. Apparent motion is detected when an infrared source with one temperature, such as a human, passes in front of an infrared source with another temperature, such as a wall. All objects above absolute zero emit energy in the form of radiation. Usually infrared radiation is invisible to the human eye but can be detected by electronic devices designed for such a purpose. The term passive in this instance means that the PIR device does not emit an infrared beam but merely passively accepts incoming infrared radiation. “Infra” meaning below our ability to detect it visually, and “Red” because this color represents the lowest energy level that our eyes can sense before it becomes invisible. Thus, infrared means below the energy level of the color red, and applies to many sources of invisible energy.

PIR detector for use in alarm systems. Lens covers area up 45ft X 45ft (90deg. Spread). Internal terminal strip for 12V/15mA DC power (9-16VDC), NC alarm contacts & tamper switch. Selectable 1-2 pulse count. Internal red "walk" LED can be disabled. Indoor use.

This motion detector can be connected to and powered by a CTB16D or a CTB08D controller. Motion will then activate the controller when in Standalone mode.

Power Line Control

(PLC) A new device Light-O-Rama uses to send commands through a power source without connecting data cables to each device.

Power Usage Utility

The LOR power usage utility is an Excel spreadsheet that can create a graph of current use versus time for a given Light-O-Rama v2 sequence. It can be used to aid in designing your layout and sequencing your lights to avoid the possibility of drawing too much current from a given controller or power feed circuit.



A formal set of conventions governing the format and control of interaction between the computer and attached hardware.


Slang for people that love inflatables.
