Intermec Device Registration Services (IDRS) is an integral part of Intermec Management Services. To use IDRS, you must have an IDRS server (DCS 3XX) in your data collection network and your devices must be IDRS-enabled. As each device turns on, it automatically registers with the IDRS server. The IDRS server stores the devices's logical name and major attributes in a database. Intermec Management Services software accesses this database to get a complete picture of your data collection network, even when the device turns off.

IEEE 802.11 standard
The IEEE 802.X standards are a set of specifications for local area networks (LAN) from The Institute of Electrical and Electronic Engineers (IEEE). Most wired networks conform to 802.3, the specification for CSMA/CD-based Ethernet networks. The 802.11 committee completed a standard for 1 and 2 Mbps wireless LANs in 1997 that has a single MAC layer for the following physical-layer technologies: Frequency Hopping Spread Spectrum, Direct Sequence Spread Spectrum, and Infrared. IEEE 802.11 HR, is an 11 Mbps version of the standard which was completed at the end of 1999.

image bands
A portion of an image, in the shape of a strip of the image. A certain number of image bands are stored in memory before printing begins. This method allows printing and imaging to take place simultaneously.

image file
An image file contains all the files you want to load onto the reader's drive C. Because drive C is a ROM drive that is implemented in flash memory, you can use DOS commands to read from drive C, but you must use special utilities to write to drive C.

The process of generating a picture of the label in printer memory.

imaging processor
Part of the 7350 Wide Area Bar Code Scanner. The imaging processor decodes all the scanned information and provides an image of each scanned bar code.

increment/decrement field
Bar code or text fields the printer automatically changes from one label to the next. For example, a batch of labels with serial number text or bar code fields that change from 001, to 002, to 003, and so on.

To move from the start of the label to the start of print. With continuous media, to advance the media over the label gap to the edge of the next label.

input device
A wand or laser scanner or other device that scans bar code information into the terminal or reader.

input/output (I/O) PC card
A type of PC card, such as a modem card, that can be used to connect the reader to another device for communications. I/O cards comply with PCMCIA Standard 2.1.

Input Manager
A Reader Services program that you use as an interface for all data input and output from the reader's COM ports, wand, scanner, and keypad. The Input Manager handles all power management tasks during data input and output.

A computer session that provides immediate feedback to input. Two-way communications between two devices.

Interactive Configuration application (IC.EXE)
A menu-driven application that lets you view the reader's current configuration, modify parameters, create configuration files, and configure the reader with any configuration file.

intercharacter delay
Amount of time between transmitting successive characters.

intercharacter gap
The space between the last element of one character and the first element of the adjacent character of a discrete bar code symbol.

interface type
An object in Conman that identifies and describes one of the following types of physical entities: file, database, application, and screen mapping. A unique name identifies each interface type.

A situation that occurs when an unwanted RF signal occupies the same frequency band as a desired signal.

Interleaved 2 of 5 Code
A bar code developed by Intermec for Computer Identics that encodes the ten digits 0 through 9. The name Interleaved 2 of 5 is derived from the method used to encode two characters. In this symbol, two characters are paired, using bars to represent the first character and the interleaved spaces to represent the second character. Each character has two wide elements and three narrow elements, for a total of five elements. The specification for this bar code is set forth in MHI/AIR USD 1. It can achieve a maximum density of 7.8 characters per inch.

interleaved bar code
A bar code in which characters are paired together using bars to represent the first character and spaces to represent the second. For example, USS-I 2/5. See also continuous code.

A DOS communications program on the reader that you use to access the drives on a host as if they were on the reader, and vice versa.

interlock switch
A switch embedded in the reader's case that locks the battery into place. The interlock switch is engaged when the battery pack locks are closed. If the interlock switch is not engaged, the reader will not operate.

interpretive field
A text field that describes the data in the associated bar code field.

A companion application to Interlnk that runs on the computer that acts as the server while Interlnk runs on the computer that is the client.

1. Internet protocol. This protocol provides a method for transmitting blocks of data (IP datagrams) between hosts. 2. For the Model 200 Controller, this is the protocol for the network layer in the TCP/IP protocol. It acts as a router for frames and is also responsible for frame addressing. It verifies it has all the frames to pass to the TCP layer and that they are in the correct order.

IP address
An internal TCP/IP protocol stack variable. This address is a network level address assigned to each device in a TCP/IP network.

Inches per second. A measurement of print speed that measures the number of inches of media that is printed each second.

1. Internet packet exchange protocol. This protocol provides a means for message packets to be exchanged on an internetwork. 2. For the Model 200 Controller, this is the protocol for the Network layer in SPX/IPX protocol. It provides a way for packets to be exchanged on a network. It acts as a router for messages to other computers, it directs incoming data to the correct local process, and is also in charge of addressing.

Interactive reader language. A high level programming language developed by Intermec for their bar code readers.

IRL Desktop
The IRL operating environment on the JANUS reader is called the IRL Desktop. This application lets you use the reader to transmit, receive, and clear data files, and to download and run IRL programs.

Interrupt request. Hardware lines over which devices such as the reader's input/output ports, the keypad, and disk drivers can send request-attention signals (commonly called "interrupts"). IRQs suspend current operations, save current work, and transfer control to a routine called an interrupt handler, which causes a specific set of instructions to be carried out by the computer's microprocessor.

Industry standard architecture. Computer circuit board design that allows various adapters to be added to the system by means of inserting plug-in cards into expansion slots.

International Organization for Standardization. An internationally accepted 7-bit character code. (The U.S. version is ASCII.)

Jumper pin. A prong used as a jumper contact to PCBs or cards. See also jumper.

A short length of conductor used to make a connection between two points or terminals in a circuit or to provide a path around a break in a circuit.

junction box
A box used for connecting height sensor cables to the imaging processor.
