RAD – Rapid Application Development
A RAD tool is software that allows a non programmer, but technically oriented person to develop an application quickly and efficiently.
These tools typically run on a Windows PC and provide a graphical environment with drag and drop objects such as boxes, lines, input fields, etc. onto a mock up display the same size as the data collection computer on which the application will eventually run.
EZBuilder, MCL and RFgenare excellent examples of RAD tools.

RADIUS – Remote Authentication Dial In User Service
RADIUS is Client/Server software and Protocol that enables remote access Servers to communicate with a central server to authenticate dial-in and network users and authorize their access to the requested system or service. RADIUS allows a company to maintain user profiles in a central Database that all remote servers can share. It provides better security, allowing a company to set up a policy that can be applied at a single administered network point. Having a central service also means that it's easier to track usage for billing and for keeping network statistics. Created by Livingston (now owned by Lucent), RADIUS is a de facto industry standard used by a number of network product companies.
RADIUS servers can authenticate Clients via EAP/TLS, LEAP, PEAP, and others.
RAM – Random Access Memory
RAM is the place in a computer where the operating system, application programs, and data in current use are kept so that they can be quickly reached by the computer's processor. RAM is much faster to read from and write to than the other kinds of storage in a computer such as the hard disk, floppy disk, and CD-ROM.
DRAM and SRAM are forms of RAM.
In barcoding, raster scanners employ
Laser diodes that are mounted on a rocker so that the beam or pattern of beams move up & down or sideways. This is done to vary the patterns across then entire of a surface in case the
Barcode is not always in the same place.
The term raster also refers to the region of a cathode ray tube (CRT) or liquid crystal display (LCD) monitor that is capable of rendering images.
Contrary to Batch, a real-time data collection computer or system is connected by wire or Wireless to a host computer or system. As data is collected, it is transmitted directly to the host application in real time.
Records management is an organizational process to ensure that organizational records creation, storage, and movement are linked to specific location and personnel.
Records management applications improve revision control, increase work efficiency, match document to personnel for security/confidentiality issues, or adhere to government regulatory requirements.
A relational Database is a collection of data items organized as a set of formally-described tables from which data can be accessed or reassembled in many different ways without having to reorganize the database tables. The relational database was invented by E. F. Coddat IBM in 1970.
The standard user and Application Program Interface (API) to a relational database is the structured query language (SQL). SQL statements are used both for interactive queries for information from a relational database and for gathering data for reports.
In Barcodes, resolution usually refers to how many data characters can be printed in a given amount of space. Resolution is usually specified in characters per inch (cpi).
Retro reflective labels have a shinny background surface. This type of label stock is often used when a long scanning distance is required. Combined with a large X Dimension and a long range scanner, retro reflective labels can be scanned from 50+ feet.
Radio Frequency is a term that refers to alternating current (AC) having characteristics such that, if the current is input to an Antenna, an electromagnetic (EM) field is generated suitable for Wireless broadcasting and/or communications. These frequencies cover a significant portion of the electromagnetic radiation spectrum, extending from nine kilohertz (9kHz), the lowest allocated wireless communications frequency to thousands of gigahertz (GHz).
When an RF current is supplied to an antenna, it gives rise to an electromagnetic field that propagates through space. This fieldis sometimes called an RF field; in less technical jargon it is a "radio wave."
AIDC industry products use UHF (400+MHz), 900MHz, 2.4GHz, and 5GHz RF equipment.
RFC – Request For Comments–Remote Function Call
A Request for Comments is a formal document from the Internet Engineering Task Force (
IETF) that is the result of committee drafting and subsequent review by interested parties. Some RFCs are informational in nature. Of those that are intended to become Internet standards, the final version of the RFC becomes the standard and no further comments or changes are permitted. Change can occur, however, through subsequent RFCs that supersede or elaborate on all or parts of previous RFCs.
A Remote Function Callis an
API to R/3 applications from
SAP. SAP customers who wish to write other applications that communicate with R/3 applications and
Databases can use the RFC interface to do so.
RFDC – Radio Frequency Data
RFDC is simply data collection that uses RF to move data.
RFgen is the name of a Rapid Application Development (
RAD) tool and
Server system by the Datamax Software Group in Eldorodo Hills, CA. This tool provides an
Interface between data collection computers and a host
Database. It can also provide an interface to
SAP, JD Edwards and Xapta. RFgen can be considered
Middleware.
RFI – Request For Information.
A Request For Information is usually sent by a potential customer to multiple vendors. The RFI will request information pertaining to the vendor, and their financial status, business practices, staff levels, services and products provided, etc.
The customer collects an RFI from multiple vendors and uses this information to make purchasing decisions.
Ryzex receives RFIs from time to time. They vary in complexity and detail and can sometimes take multiple people and many man hours to complete.
RFIs are very similar to RFQs.
RFID – Radio Frequency Identification
Unlike Barcodes, RFID is a technology that incorporates radio frequencies to identify objects. One advantage of RFID is that it does not necessarily require direct contact or line-of-sight scanning.
An RFID system consists of three components: a Transponder (tag), Interrogator (reader) and an Air Interface between the two. The interrogator transmits an RF signal that activates the transponder. When activated, the transponder transmits data back to the interrogator.
The data can then be used to update a Database, notify a programmable logic controller that an action should occur or any number of other functions.
Some RFID transponders are read/write and have significant data storage capacity.
A Request For Quote is usually sent by a potential customer to multiple vendors. The RFQ will request information pertaining to the vendor, and the services and products provided along with actual quotes for said services and products.
The customer collects RFQs from multiple vendors and uses this information to make purchasing decisions.
Ryzex receives RFQs from time to time. They vary in complexity and detail and can sometimes take multiple people and many man hours to complete.
RFQs are very similar to RFIs.
Telephone jacks registered in the U.S. with the FCC, sometimes described as RJ-XX. These are a series of telephone connection Interfaces (receptacle and plug).
RJ11-Common telephone jack. Usually four wires.
RJ14 –similar to RJ11 but supports two phone lines.
RJ45 –Used for digital transmissions (networking).
Robust is an adjective commonly applied in marketing literature to information technology products in several ways. It derives from the Latin robustus, meaning "strength."
1) A robust product can be one that doesn't break easily. Thus, an operating systemin which any individual application can fail without disturbing the operating system or other applications can be said to be robust.
2) Robust is also sometimes used to mean a product or system of products designed with a full complement of capabilities. Thus, in the context some of the products Ryzex sells,
Wavelink’s Mobile Manager software is considered more robust than
Intermec’s MobileLAN Manager software.
RoHS – Restriction of the use of certain Hazardous Substances in electrical and electronic equipment
The RoHS Directive, EU Directive 2002/95/EG, which will go into affect on July 1, 2006 in Europe, mandates that electrical and electronic products (EEE) put in the market within the European Union (EU) shall contain restrictive levels of the following substances:
- Lead (Pb)
- Cadmium (Cd)
- Mercury (Hg)
- Hexavalent Chromium (Cr6+)
- Polybrominated Biphenyls (PBB)
- Polybrominated Diphenyl Ethers (PBDE)
This Directive, which aims to protect human health and the environment and mirrors the Directive on Waste Electrical and Electronic Equipment (WEEE), applies to electrical and electronic equipment that is dependent on electric or electromagnetic fields in order to work properly and applies to some equipment used for the generation, transfer, and measurement of such currents and fields designed for use with a voltage rating not exceeding 1,000 volts for alternating current (
AC) and 1,500 volts for direct current (
DC).
The RoHS/WEEE directive does not call for a total elimination of these substances. It mandates that the homogeneous materials within complaint products, or materials that cannot be mechanically disjointed into different materials, contain the levels of the six restricted substances below the maximum concentration levels.
Manufacturers must ensure that their products,and their components, comply.
ROI - Return On Investment
For a given use of money in an enterprise, the ROI is how much profit or cost saving is realized. An ROI calculation is sometimes used along with other approaches to develop a business case for a given proposal. The overall ROI for an enterprise is sometimes used as a way to grade how well a company is managed. If an enterprise has immediate objectives of getting market revenue share, building infrastructure, positioning itself for sale, or other objectives, a return on investment might be measured in terms of meeting one or more of these objectives rather than in immediate profit or cost saving.
Ryzex customers often realize a significant ROI after an
AIDC system implementation.
ROM is "built-in" computer memory containing data that normally can only be read, not written to. ROM contains the programming that allows your computer to be "booted up" or regenerated each time you turn it on. Unlike a computer's random access memory (RAM), the data in ROM is not lost when the computer power is turned off. The ROM is sustained by a small long-life battery in your computer.
Other forms of ROM include PROM, EPROMand EEPROM.
On a network, a router is a device or, in some cases, software in a computer, that determines the next network point to which a
Packet should be forwarded toward its destination. The router is connected to at least two networks and decides which way to send each information packet based on its current understanding of the state of the networks it is connected to and based on destination
IP address.
A more intelligent form of a router is a
Gateway.
RPC - Reusable Plastic Container
RPC referrers to any container made of plastic that is designed to be used repeatedly to contain same or many types of products.
In the AIDC industry RPCs are identified with Barcodes, touch memory or RFID tags.
RP-TNC - Reverse Polarity - Threaded Neill Concelman Connector
Named for its inventors, this connector is designed as a threaded version of the BNC, the TNC series features screw threads for mating. TNC are miniature, threaded weatherproof units with a constant 50 Ω impedance and they operate from 0 -11 GHz. There are two types of TNC connectors: Standard and Reverse Polarity. Reverse polarity is a keying system that prevents RP connectors from mating with standard Interface connectors. This is done by inserting female contacts into plugs and male contacts into jacks or by using reverse threading. RP-TNC female connectors are provided on many access points for remote Antenna connections. The RP-TNC male connector is used on many antenna cables.
RS232 is a long-established standard that describes the physical Interface and protocol for relatively low-speed serial data communication between computers and related devices. RS-232 is the interface that your computer uses to talk to and exchange data with your modem and other serial devices. RS232 supports up to 256Kbps and cable lengths of up to 50 ft. Many data collection terminals have RS232 ports. RS232 connectors are available in different form factors. This 9 pin version is most common and is found on the back of most PCs.
RSA is an Internet encryption and authentication system that uses an algorithm developed in 1977 by Ron Rivest, Adi Shamir, and Leonard Adleman. The RSA algorithm is the most commonly used encryption and authentication algorithm and utilizes public and private keys. It is included as part of the Web browsers from Microsoft and Netscape and it's part of Lotus Notes, Intuit's Quicken, and many other products. The encryption system is owned by RSA Security. The company licenses the algorithm technologies and also sells development kits. The technologies are part of existing or proposed Web, Internet, and computing standards.
