Term Definition
RDS

Radio Data System, or RDS, is a communications protocol standard for embedding small amounts of digital information in conventional FM radio broadcasts. RDS standards several types of information transmitted, including time, station identification and programming information.

Rectifier

A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC) which flows in only one direction. The process is known as rectification.

Relay

An electromagnetic device with one or more sets of contacts that change position by the magnetic attraction of a coil to an armature.

Renard

A unique serial communication protocol developed solely for allowing Vixen to communicate to DIYC light controllers. Also applies to the dimming firmware used by many DIYC (Do It Yourself Christmas) light controllers.

RGB

Red Green Blue. Mix these three colors to get almost any color of the rainbow. RGB LEDs are really three small LEDS (one red, one green and one blue) in one enclosure so it looks like the bulb is changing colors on command.

RJ45

Registered Jack 45. A data plug or jack standard that allows for the connection of eight wires. It is similar to the modular plug on telephones (which are usually RJ11), though bigger. It is commonly used in Ethernet cabling and so its components (cable, female connectors, male connectors) are readily available and inexpensive.

Ropelight

Miniature lights encased in a plastic rope that attempts to look like neon.

RS232

A telecommunications protocol, Recommended Standard 232 was originally designed to connect teletypes with modems; it has survived to this day as the way computer serial ports send out data. RS232 is implemented in a variety of connectors, but is most commonly seen in the DB9 and DB25 devices. It uses nine wires and supports transmitted data, received data, request to send, carrier detect and ring indicator. It is used in Christmas lights by as the physical layer between PC serial ports and Christmas lights controllers.

RS485

A telecommunications protocol, Recommended Standard 485 is typically used in building automation, the programming of logic controllers, sound system control, lighting control and video surveillance camera control. It is a two-wire system that uses a differential form of signaling that supports the transmission of data packets. It can be used over a long distance and supports multi-point connections. It is used in Christmas lights as a distribution system for light controllers signaling devices, sometimes using the DMX512 protocol.

Sequence

A sequence is an ordered list of objects or events. Like a set, it contains members (also called elements or terms), and the number of terms (possibly infinite) is called the length of the sequence. Unlike a set, order matters, and exactly the same elements can appear multiple times at different positions in the sequence. A sequence is a discrete function.

Sequence Backup Utility

Sequence back up management. Automatically make backups of each saved file. Allows you to get the old version back.

ServoDog 8

The ServoDog is more than just an 8 channel servo board. The 8 channels can run either in servo mode or as standard logic level outputs to power low current items such as LEDs or Solid State Relays. In addition two of the channels can be configured as high current PWM channels with their own power input to run DC motors, LED spot lights etc...

Shrink Wrap

Shrink wrap, also shrinkwrap or shrink film, is a material made up of polymer plastic film. When heat is applied it shrinks tightly over whatever it is covering. Heat can be applied with a hand held heat gun (electric or gas) or the product and film can pass through a heat tunnel on a conveyor.

Snubber

A snubber is a device used to suppress ("snub") voltage transients in electrical systems. They are mostly used on LED's.

Spiral Tree

A mega-tree, Scott Weber created, that has lights running from top to bottom in a spiral fashion unlike a typical mega-tree, up and down.
