Ingress Protection – IPxx. IP refer to an international classification system for the enclosures of electrical equipment against the intrusion of foreign bodies into the equipment (i.e., tools, dust, fingers, moisture). This classification system utilises the letters "IP" ("Ingress Protection") followed by two digits that refer to the degrees of protection.

IP54 – protection from dust and splashed water



Intrinsically Safe – A term used to describe rugged mobile computers that can be used in hazardous environments where explosives or flammable gasses may be present. The power usage of the device is such that it is below the levels required to set off an explosion.



Keyboard Wedge – An interface that allows peripheral devices, such as basic bar code scanner, to plug into a computer. The "wedge" converts scanned data to "keyboard strokes" so the PC can interpret the data.

LCD – Liquid Crystal Display.


MMT – Materials Management Tool. An application designed to connect real world devices such as bar code scanners, Pick To Light systems and RFID equipment to ERP systems including SAP and others. Originally designed for SAP long before SAP had an offering for a bar code solution for their WM an IM modules. Certified by SAP Labs in Toyko in 1998, MMT still utilises a superior interfacing technology to connect the operations of the warehouse back to SAP, providing sub second response time to the warehouse along with the ability to operate for periods when SAP connectivity may be unavailable.


NEL – Narrow Edge Leading. The narrow edge of the label is leading off the roll.



PalmOS – Palm Operating System

PCMCIA – Personal Computer Memory Card International Association. PCMCIA cards can be used for wireless connectivity, modems and other functions in laptops, notebooks and PC’s that may be lacking them natively.

Polypropylene – The most common variety of synthetic materials used in bar code labels. Far more durable than paper and usually tear proof.

POS – Point of Sale.



RFID – Radio Frequency Identification. RFID is an automatic identification method relying on storing and remotely retrieving data on a tag. The tag has an embedded antenna for communicating with the RFID reader. Tags can be "active" and include a battery or other power source, or more commonly "passive" where the tag gets its energy from the reader. Passive tags receive a "big wave" of radio energy from the reader and reflect or echo back a "little wave" containing their identity.

RS232 – Recommended Standard 232. Commonly used in computer serial ports and printers, becoming less popular since the late 1990’s as other communications have become more popular including USB.

RoHS Compliance – Restriction of Hazardous Substances. Also known as Lead-Free or Directive 2002/95/EC, originates from the European Union and restricts the use of six hazardous materials found in electrical and electronic products. Australia is also looking to adopt this directive. See www.rohsguide.com for further information.
