Computer Description
Portable Computers
Hand-Held Computers are used by mobile workers to quick-
ly and accurately capture information, print reports, dis-
patch competitive analysis, and to support field mainte-
nance and sales automation.
Technical advancements help make today’s hand-held com-
puters suitable for many other uses.
These units are battery operated, making them extremely
portable and well-suited for utility, public safety, trans-
portation, and field service operations.
Typically, programs or data are loaded (“downloaded”) into
the hand-held computer from a PC or mainframe. Depend-
ing upon the options built into the computer, entries are
made via screen contact, a keyboard or a scanner. The
hand-held computer typically contains (or can access) a da-
tabase with customer and product information. It does cal-
culations based on product movement, sends information to
a printer, and often sends data to a host computer in real
time or at the end of the work day.

6620 Computer
The 6620 Hand-Held Computer is a versatile portable data
collection device. It has a large, easily-read display, pen-
based data entry, and the power and speed provided by an
AMD X5-133 MHz processor. With extensive memory op-
tions and the Windows 95 operating system, the 6620 Com-
puter is a powerful, full-function PC with all of the rugged-
ness and portablility we design into every product.

Software Compatibility
Norand equips the computer with software for battery
charging and for communicating to peripheral devices. The
computer also has a software interface for display control
when using windows-type programs.
Since the computer uses the Windows 95 operating system,
there are many general programs and publications avail-
able for use with the computer.
Computer Description
The following illustrations and text will familiarize you
with the external features of the 6620 Computer.
At the beginning of each work day, inspect the unit and
make sure that the following components are secure:
" Battery compartment door
" PC card compartment door
" Special pen
" Handstrap
" External connectors
" Optional accessory pod
Correct any problems discovered during this inspection be-
fore using the computer.

Display
The display shows computer or battery status messages,
entries, the most recent scan, customer or product lists, cal-
culations, and prompts that require a response from you.
The cursor controls can be shifted to let you adjust the dis-
play brightness and contrast (monochrome display only) for
best viewing.

Pen (input device)
You can use a scanner or the special pen provided with the
computer to make manual entries. The special (passive)
pen has a unique tip designed to reduce touch-screen wear
and scratching. This pen normally performs the function of
the left mouse button; keys located near the display on the
computer allow you to change the pen function to that of a
right mouse button.
Battery compartment
The easy-access battery compartment contains a recharge-
able battery pack. This is a “smart” battery pack because it
has internal electronics that monitor and can report the
condition of the battery pack. A sensor in the battery
compartment detects when the door is in place and fully
latched: the unit will not work unless the door is latched.
Infrared window
An infrared serial port (IrDA standard) provides a wireless,
two-way, line-of-sight communication path between the
computer and peripheral devices.
Connectors
There are six external connectors at various locations (see
figures 1-1 and 1-3) on the Model 6620 Computer. An RJ-45
jack connects to an optional internal modem (jack is pres-
ent, whether a modem is installed, or not). Other connectors
include a 9-pin serial port, DC power input jack, a mini-
DIN keyboard connector, a docking connector, and a termi-
nal-to-dock antenna connector
SECTION 1 " General Information
6620 Hand-Held Computer User’s Guide 1-7
Serial Port
This 9-pin D-subminiature connector supports RS-232 sig-
nals for two-way communication between peripheral de-
vices and is capable of supporting a 5 volt bar code scanner.
When the computer is docked, these same signals are car-
ried on the docking connector and are accessed via the
RS-232 port on the dock.
DC power input jack
This jack allows you to power and recharge the computer
from either an external 12 volt ac--dc power supply or an
adapter cable to a vehicle cigarrette lighter socket or auxil-
iary power source.
Mini-DIN connector (keyboard)
This 6-pin miniature DIN connector directly supports PS/2
or PC AT keyboards through an adapter cable. Keyboard
signals are also available on the docking connector to per-
mit the use of an external keyboard when the computer is
docked. You can connect a wedge-type scanner or mouse to
the computer via the keyboard connector. A special adapter
is required to connect a standard, off-the-shelf mouse.
Docking connector
This connector provides a reliable electrical interface be-
tween the computer and a vehicle or fixed-mount docking
station. Both two-way communication signals and power
for operating and recharging the battery pack pass through
this connector.

Antenna connector (terminal-to-dock)
This connector mates with a connector in the dock for use
with an external, remotely-located radio antenna.

Status indicators
Three bi-color light-emitting diode (LED) indicators located
between keys on the front panel tell you the status of vari-
ous power sources for the computer. A fourth LED comes
on (green only) whenever the optional hard drive is being
accessed. Figure 1-5 identifies each of these LEDs.
Table 1-1 shows the meanings for each indicator.
