Introduction
""""""""""""""""""""""""""""
The NorandR 6920 Communications Server" by Intermec
Technologies Corporation provides a flexible link between
either a host computer in the central office or a depot's data
processing system and the handĆheld computers used by
route salespeople.
Overview
The 6920 Communications Server" is the latest new
offering in the line of open systems communications and
connectivity software based on Microsoft Windows NT and
95 (98). It is an evolution of the NORAND 4000 Series
Communications products. The Norand 6920
Communications Server" is a storeĆandĆforward
communications software server based on traditional
NORAND protocols and data exchange methodologies. It is
a replacement for 4920 installations, and can serve as a
direct replacement for certain implementations of the 492X
Telecommunications Package," 4980 and 4985 Network
Controllers, and 6980/6985 Network Managers. Upgrading
and migration should be relatively painless as original
functionality and connectivity has been a focus of the
migration.
The Norand 6920 Communications Server" is a commuĆ
nications server software application. It runs on IntelĆ
Introduction SECTION 1

R
6920 Communications Server Reference Manual
based hardware platforms, Windows 95 (98) and NT operatĆ
ing systems. The server provides a gateway between
mobile users and the enterprise. It is a replacement for the
492X Telecommunications Packages." New technologies
can have a migration path for the old systems without
throwing away old applications or host system front ends.
For those migrating from the 4920 Telecommunications
Packages," the list of functionality provided by the 6920
Communications Server" is essentially 4920
Telecommunications Packages" with new features of
Transmission Control Protocol over Internet Protocol
(TCP/IP) support, a new Graphical User Interface (GUI),
and multiĆtasking to support processing of data while
continuing to carry on sessions. Like the 4920
Telecommunications Packages," the 6920 Communications
Server" has the ability to communicate with remote and
docked devices. It is the migration path for all utilizing
hardware and communications protocols.
You now have the flexibility to choose your hardware and
version of operating system to meet your organizational
needs. The system is decoupled and layered into modules,
and has broken the monolithic mold of its predecessors.
There are no longer requirements for a fixed package of
DOS, proprietary communications cards with limited
configurations, and proprietary networks.
EXAMPLE: A mix of several protocols can be used on the same server at the
same time without the restrictions of the “4920 Telecommunications
Packages.” There are no longer limitations on the number of specific
types of ports available, such as in previous releases, multiple
RS-485 lines may be configured on a single “6920 Communications
Server.” The system may be configured with two ports to communicate on a 10 Mbps Ethernet line using TCP/IP, another two on 115.2
Kbps RS-485 lines using NPCP (release 2), and another six on modem lines, three at 28.8 Kbps and three more at 9600 bps both using
TTY. A combination of several different models of hand-held computers could communicate with the “6920 Communications Server”
simultaneously.

Improvements
Several upgrades have been made to the product to improve
upon the 4920 Telecommunications Package." Most visible
is the user interface. Other improvements to the internal
process handling and communications infrastructure have
been made under the covers. You will find that the 6920
Communications Server" handles communications
processes more efficiently, potentially improving throughput
using the same protocols and speeds as its predecessors.
Additional new processes and ways to use formatting files
are available. Subsequent releases with even more
features and functionally are already in the works.
System administrators and server users now have a GUI to
monitor system status and user progress. Standard
window views show the daily data collection activities, all
system communication ports, and any associated programs
that may be running, such as data formatters. Using the
graphic environment of Windows NT and 95 (98), you may
now spot system problems and anomalies by glancing at the
operators console. The display may be customized to show
the element that someone performing a specific job would
want to see. All of the GUI improvements have been made
using standard 32Ćbit Windows tools, so the views are
flexible and configurable.
There are three major portions of the screen that may be
sized for optimal viewing.
" The first addition is the window that shows active and
inactive users.
" The next window lets you view or monitor processes
and their current status to determine which of the sysĆ
tem processes are set up.
Introduction SECTION 1
1-4 Norand
R
6920 Communications Server Reference Manual
" The last addition on the display is a port (channel)
monitor. It shows each of the configured ports and
their current status. For instance, the system adminĆ
istrator may want to watch modem ports. A view may
be built that constantly monitors all of the ports with
large colored icons that indicate the status of each port
including information about when it was last used, the
size of the transaction, and current status of that port.
The NT platform is a big plus for the 6920 CommunicaĆ
tions Server." When the NORAND server software is
coupled with the powerful NT Server operating system, you
have the ability to use other network functions like DHCP
service, file and print services, and Internet server functionĆ
ally included with the operating system. The addition of
Ethernet to the product line of handĆheld computers is a
perfect marriage of these technologies. Existing applicaĆ
tions can be converted to use the Ethernet TCP/IP functionĆ
ality of the 6210, 6300 Series, and 6600 Series HandĆHeld
Computers with small application changes for developers
who have used the NORAND programming libraries.

Booting Hand-Held Computers
The 4000 and 6000 Series must have the operating system,
programs, and (sometimes) data sent to them when bringĆ
ing them into service for the first time. Cold boot" is the
industry jargon for bringing a computer to normal operatĆ
ing conditions when it has been without power. This term
is adopted to describe the same process for starting our
4000 and 6000 Series Computers.
This explanation makes clear the need for a convenient
method for cold booting 4000 and 6000 Series Computers.
The 6920 Communications Server" meets that need. By
placing the required files in the appropriate 6920 directory,
computers can be booted almost as easily as dayĆtoĆday
communication with them.
If 4000 Series Computers run one application program,
copy the application software into the boot directory defined
in System Properties." At communication time, the 6920
Communications Server" sends the only application
available.
The 6000 Series applications are loaded into the download
directory defined in System Properties." 6000 Series apĆ
plications are commonly named according to the computer
model they were created for, such as the following:
" 6100 Computers 6100IPL.INC
" 6210 Computers 6200IPL.INC
" 6300 Computers 6300IPL.INC

Cold Boot Capabilities
The 6920 Communications Server" provides protocols speĆ
cifically to handle cold boot of the following:
4000 Series Computers
4000 Series coldĆbooting is provided using NPCP local comĆ
puters and Ymodem protocol for remote single routes. The
4000 Series application should reside in the 6920 CommuĆ
nications Server" Boot Directory defined in System ProperĆ
ties."
6000 Series Computers
6000 Series coldĆbooting is provided using NPCP, NRInet,
and TTY protocols. The 6000 Series application file should
be placed in the Download Directory defined in System
Properties."

Initial Download Capability
The 6920 Communications Server" supports initial downĆ
load (IDL) only if the computer application program is set up
to handle it and data files are defined in the 6920 CommuĆ
nications Server" as IDL files. A byte located in the upload
session control file (SCNTRL) is normally set to a 1" during
the boot process.
Data flow from the 6920 Communications Server" to the
computer begins when the computer requests a download.
This first download after a computer is booted is called IniĆ
tial DownLoad or IDL. Assuming the 6920 CommunicaĆ
tions Server" is prepared for IDL and the computer applicaĆ
tion allows it, the 6920 Communications Server"
downloads to the computer.
People familiar with the computer application planned for
use with the 6920 Communications Server" are the best
sources for IDL information. Procedures for IDL vary wideĆ
ly from one application to another.
SECTION 2 Communication with Client Computers
Norand
R
6920 Communications Server Reference Manual 2-5
Data Flow
Data flow from the 6920 Communications Server" begins
with the computer uploading the stored data, then receivĆ
ing a download. Download is done by scheduled data, using
the Import Data method or by using a download request.
The communication program uses the request and activaĆ
tion databases to determine what files or data the computer
should receive. Then it sends the appropriate file or files to
the computer. Specific files can also be requested" by the
computer using a special download request (DWNLRQ) forĆ
mat.
The computer upload is stored in an upload data file. The
communication program also generates a log of its transacĆ
tions with the computer and places the contents in an
Event Log" file (available through EVENTLOG.EXE).
The first block of upload data sent from the computer conĆ
tains information used by the 6920 Communications ServĆ
er:"
" Route ID
" Application version
" Flash version
" IDL flag
"

Event Log
The 6920 Communications Server" generates an Event
Log" file in each communication session. The file consists of
various records with detailed statistics about all applicaĆ
tions.
Event Log" information is stored in an ODBC compliant
database which can be viewed using the 6920 Event Log"
application. Each record recorded in the Event Log" has a
unique key. Each entry contains five fields:
" Type Information, warning, critical
" Date Date (DD/MM/YY)
" Time Time (HH:MM)
" Module Application which reported message
" Message Message text
The Event Log" is contained in a Microsoft Access dataĆ
base located in the C:\6920\DB" subdirectory. The
6920.MDB file should be periodically archived and deleted
as a maintenance practice.
