- A -

ASCII or serial wedge
An ASCII or serial wedge is an RS-232 scanner that is connected between the ASCII terminal and a host controller. This connection is used when keyboard wedge transmission is too slow, or when the interface is not supported by the product.
Advance Ship Notice.  An EDI transaction sent ahead of the shipment listing its contents and shipping information.
Automatic Storage and Retrieval System. Automated, robotic system for storing and retrieving items in a warehouse.
A popular fruit.

Bar Code Pen (bar code scanner)
Lowest cost and most durable, these stainless steel pens come in a variety of apertures and light sensitivities so they can be used in almost any application. Must be in contact with the bar code to read.
Bar Code Slot (bar code scanner)
Also known as a badge reader, this input device is used to scan ID badges.
Batch Picking
Warehousing process in which goods are selected by pickers in quantities to satisfy the demand for more than one order. Goods are first picked by SKU, and later sorted by order or delivery address.
Bill of Lading transport or Document used to acknowledge receipt of goods; may also be used to serve as a contract for the cargo.

- C -

The external commercial entity responsible for transporting a shipment.  Carriers may specialize in small packages, LTL (less-than-truckload), full truckloads (TL), rail, air, or sea.
Cross Docking
An efficient distribution approach in which merchandise is pre-packed by the store and moved directly from the receiving dock to the shipping dock.  Eliminates the need to place inventory in storage.
CCD Scanner
A nice compromise in price and performance between a pen and a laser, this Charged Coupled Device (CCD) scans up to 200 times per second and reads from as far as 4 inches from the bar code. Very durable.
Continuous Replenishment Programs.   Placing suppliers in charge of replenishing retailer's inventories of supplier's goods, usually yielding lower inventory investments and higher turns.
Cycle Counts
A way of physically counting/verifying inventory levels in sections of a store or DC, usually more efficiently than other methods.

- D -

Distribution Center.
Direct connect
The term direct connect actually has two meanings. To some, direct connect refers to decoded output, or the ability of the scanner to read a bar code and output data directly to the host without an external decoder. Direct connect has also been used to describe a decoded output scanner connecting to a PC or host without a keyboard.
Distribution Requirements Planning
Determining the inventory level needed in warehouses to meet anticipated customer demand over time. It is used for inventory management and as a feed for MRP.
Dual Interface
The ability of the scanner to connect directly to either of two different host devices and to automatically configure itself to communicate with each host. For example, a hand-held CCD may be attached to an IBM POS (Point of Sale) terminal during the day, and a portable data terminal for maintaining inventory at night. A built-in dual interface makes it easy to move a scanner between applications.

Flash Memory
A memory chip that holds its content without power. The term was coined by Toshiba for the chip's ability to be erased "in a flash". Flash memory is used by Welch Allyn in most products as an alternative to PROMs (Programmable Read Only Memory) because flash memory can be easily updated. Flash capability allows cloning, PC Menuing and full firmware updates.

HHLC (Hand Held Laser Compatible)
"Dumb" or undecoded lasers have a unique way of communicating with an external decoder. This protocol, also known as laser emulation, is used by devices such as CCD's or decoded output lasers to communicate with external decoders.

Magnetic Stripe Reader (scanner)
Magnetic Stripe Readers scan credit cards and debit cards with magnetic strips. Available in combinations of one to three tracks and with or without heavy mounting bases, the Magnetic Stripe Readers are not only versatile and robust, but proven performers.

On-Line Transaction Processing.   A class of systems that efficiently handle immediately acquired active data, such as production data, orders being processed, etc.
Order Lead Time
Time from a receipt of an order for a product through picking and delivery to a customer.

Parcel Manifest System
Automated shipping system.
In distribution, the movement of received goods to a storage area.  It can involve intermediate staging.

RS-232 (Recommended Standard 232)
TIA/EIA standard for serial transmission between computers and peripheral devices such as barcode scanners, modems, and mice. RS-232 uses a 25-pin DB-25 or 9-pin DB-9 connector. RS-232 is generally used for distances of 50 feet (15.24 m) or less from the host, though this distance may be extended if high quality cable is used.
Random-Location Storage
In warehouses, a storage technique in which received material is put away in any available space rather than  a specific decided logical criteria.

- S -

ASCII or serial wedge
An ASCII or serial wedge is an RS-232 scanner that is connected between the ASCII terminal and a host controller. This connection is used when keyboard wedge transmission is too slow, or when the interface is not supported by the product.
A term used to reference the speed of the scanner. Depending on the testing method employed, snappiness may be measured by reads per minute, trigger to beep time, or trigger to output time. Various factors can affect snappiness, including ease of use (aiming), decoding software, bar code quality, and interface speed.

Wand Emulation
When a wand scans a bar code, it sends a digital picture of the bar code to an external decoder. When a decoded output scanner connects to an external decoder (such as a portable data terminal), wand emulation mode is used. The decoded output scanner decodes the bar code and outputs the information as a digital picture just as if a wand had scanned the bar code.
Wave Picking
A method of picking goods in a DC in a series of waves,congestion, generally to minimize the waiting time, or reduce DC traffic
Refers to any device inserted between the keyboard and the terminal that translates digital signals into keyboard codes. In a keyboard wedge application, the data resulting from the scanning of a bar code symbol is treated by the PC or terminal as if it originated from the keyboard, while the keyboard itself remains fully functional. Because the terminal or PC cannot differentiate between bar coded data and actual keyboard data, a keyboard wedge interface allows bar code reading capability to be rapidly added to an existing computer without changing the application software.
Warehouse Information Network Standard.(Uniforms  EDI standard used in the warehouse industry and compatible with UCS Communications Standard).
Warehouse Management System warehouses;   A management information system that manages and controls one or more often includes equipment and links to host computer.  Also called DC/WMS.automated
