one form of a signal to another that is suitable for transmission
over communication circuits, typically from digital to analog and
then from analog to digital.

moving beam bar
A scanning device that is used by mechanically or electronically
moving the optical geometry.
Materials requirements planning. MRP and MRP II are phases in developing
computerized methods to plan the use of company resources, such
as raw materials, vendors, production equipment, and processes.
One of the disks that Intermec ships with your JANUS reader. This
disk contains commands and device drivers. Some of these commands
and drivers are already installed on the reader. This disk also
contains applications, such as INTERLNK.EXE, MkImage, and PutImage.
A bar code symbology that is a modified version of Plessey code.
It is fixed length, continuous, and non self-checking. This code
is used to mark retail shelves for inventory reordering. The character
set is 0 - 9 plus additional symbols.
The address of the COM port when you are using Multi-Drop communications
protocol. Each Multi-Drop address has unique POL and SEL characters
that are automatically set when you configure the address.
Communications protocol similar to Polling Mode D, used when connecting
multiple readers to a port concentrator. In Multi-Drop, each reader
on the line must be assigned a unique POL and SEL character. Multi-Drop
operates only at 2400 baud or higher and cannot be modified.
A bar code symbol that takes the form <start code space data
stop code>. Multiple-read symbol are stored in the reader's
buffer until a command to transmit is received or until a regular
symbol (a symbol with no leading space) is scanned. See regular

This results in the appearance that several programs are running
at the same time.
The ratio between the widths of wide elements and narrow elements
in a two-width symbology.
A high-level interprocess communication facility that allows bidirectional,
multipoint communications between processes. In an OS/2 LAN Server

divided by the overall symbol length, measured from the leading
edge of the start code to the trailing edge of the stop code.
1. Network communications process. Enables communication between
DCM and remote application programs. NetComs are necessary when
the target application is operating on a node that DCM does not
reside on (remote node.) 2. Applications communicate with the Model
200 Controller through network communications processes called NetComms.
NetComms are responsible for safely routing data from remote applications
across a network to the controller and back.
