Communications

For terminals being us ed in a direct communicat ions (batch) environme nt or a Spectrum One
network environment, applications are transferred from a host computer to the terminal:

!

over a communications line using a null modem connected to the cradle
OR

!

throughthe PC Adapter.

The procedure uses the SENDHEX command on the host computer and the Program Loader
function (from Command Mode) on the terminal.

Note: For details on the SENDHEX command, refer to the Series 3000

Application Programmer's Manual.

Other software may be used in place of SENDHEX.

Chapter 4

Spectrum24 RF Terminal Setup

Spectrum24 Terminals

In Spectrum24 terminals, wireless connectivity is accomplished using standard
communications protocols. Because they are standard, the protocols are generalized and take
up considerably more space on the terminal’s NVM than was required for Spectrum One
terminals. Because there is less space available in NVM for application files, the terminal
operates with an additional megabyte of non-volatile memory or flash disk. This extra
memory is used to reduce not only the boot times but also the time and resources required to
load applications into the terminal. The flash disk also offers the possibility of running
multiple applicati ons f rom the same te r minal (r efer to the section Multiple Applications on
the Same Term inal for more information. With version 3.03 or later of the system software
(LWP . HEX ), th e termin al can also run dia gn osti c tools.

Accessing the Flash Disk

The flash disk is accessed through a drive r, FLASHDSK.SYS, which makes the flash disk
appear to a program as another disk drive (E:). The drive has characteristics of fast re ading
but slow writing (e.g., even for the smallest files, the write process takes 3-4 seconds). These
characteristics make it ideal for files that are written once, accessed often, and seldom
updated.

®

We recommend that you use the flash disk (E:) mainly for application and configuration file
storage. T o avoid overwriting the flash disk by mistake, the flash disk is set to read-only mode
for normal operation. The software installation or application software takes care of write/
read mode switching for you.

Series 3800 Product Reference Guide

Standard Spectrum24 Software

The Series 384X comes with the system software installed, including:

!

Spectrum24 radio drivers

!

TCP/IP software

!

configuration files

!

various utilities.

A BIOS of version 1.09 or later is required.
The default files c ov er mo st expecte d ins tallatio n s/i nitial izat ions with minor changes as

detailed in this chapter.
If your requirements are more advanced, refer to the Spectrum24 Network Development Kit

documentation for more information on the Spectrum24 RF network, SLAODI.COM, the
Symbol-provided ODI driver, and the configuration file setups required for various
platforms.

Boot Options & Internet Addressing

Each Series 384X requires a unique internet address (IP address), allowing messages it sends
and receives to be correctly routed over networks conforming to the TCP/IP protocol
standards. These addresses can be administered and entered manually, or administered and
allocated by a server on the network.

By default, the Series 3800 uses NOBOOT (manual entry) to define the IP address. To set the
IP address, use the CFG24 utility described later in this chapter in the section Initializi ng th e
Series 384X.

Two protocols are d efined for the IP address allocation on the network: BOO TP and DHCP.
T o allocate IP addresses through a BOOTP or DHCP server , you must change the boot option
in the configurator using the Boot Mode parameter .

Series 3800 Product Reference Guide

Compatibility Issues When Updating

While the order in which software packages are loaded is not important, we recommend
loading the system files, LWP .HE X, first, before loading any application files. You don’t have
to reload existing applications that conformed to previous standards for flash disk
applications. Loading just the s ys tem files allows the o ld applications to run wi th updated
system software.

Note:

Some configuration changes may be required.

Compli c at ions: N am i n g Applicat ions

In versions of LWP.HEX for flash disk terminals prior to version 3.03, parameters were
defined in N ET.CFG to specify the applicat ions t hat would run on the t erminal. If only one
application was used and no appl ications were defined in NET.CFG, the system gave the
application the default name, APP. This can cause problems if you plan to add more
applications to terminals using version 3.03 HEX files.

With LWP.HEX 3.03, the application entries in NET.CFG are not longer required. The
system now decides which applications are installed on the terminal by scanning the flash
disk’s directories and files. If you had an original application with the default name APP, it
will show up in the application selection menu as APP. If you updated that old application
(e.g., created a version 3.03 HEX file of the application), the application selection menu will
contain both versions, one called APP and one by the “real” name (e.g., STEP).

Because of this potenti al problem, if ALL the software on the flash disk is being replaced in
the update, we re commend reformatting the fl ash disk using FLSHFMT. Reformatting delete s
ALL th e f iles on the flash di sk and eliminates this duplication.

Note: DO NOT run the FLSHFMT utility unless all the HEX files,

including LWP.HEX, ar e avai labl e to rec reat e the fl ash disk file
system.

Complications: Syst em Parameters

In flash disk ter min als with a LWP . HEX ve rsion pr ior to 3.03 , some system parameters were
changeable only by editing NET.CFG (e.g., power management mode, boot mode, and
diversity). These parameters were not saved in the radio flash.

4-20

Spectrum24 Terminal Setup

When the LWP.HEX is updated to 3.03, these values revert to the defaults. Be sure to check
them after LWP.HEX is installed. In particular, verify whether a BOOTP or DHCP server is
being used to allocate IP addresses. The default boot mode in version 3.03 is manual entry of
IP addresses. The terminal enters the configurator during the first terminal initialization after
the LWP.HEX upgrade, allowing you to check the settings.

Multiple Applicati on s o n the Same Terminal

The system files (from L WP . HEX) fill over 200 KB of the flash disk’s 1 MB. Current standard
applications such as STEP or TN clients require between 100 KB and 150 KB of flash disk.
This leaves ample space for inst allin g more than one a pplication on a single Serie s 384X.
T erminals have been configured to run as many as four applications, with a maximum of five
applications allowed.

Individual applications may require special terminal configurations that can only be set at
boot time, such as RAM disk size. The TN clients require configuring a minimum-size R AM
disk (<100 KB) because their limiting resource is program execution space. STEP , on the other
hand, uses the RAM disk to hold forms. Some STEP application implementations use for m s
extensively and require a larger RAM disk (>100 KB). The application loaded last defines the
size of the RAM Disk for all applications on the flash disk.

Note: The system files conta in e d in the LWP.H EX ha ve the RAM dis k

defined as 80 KB.
It is possible with multiple a ppl icatio ns to have applicat ions co-

existing on the terminal with conflicting memory requirements. If this
occurs, work out a compromise value that both applications can work
with before loading the files.

If mult ip le applications ar e insta l led on t h e Seri es 384 X, a me n u is prese n t e d during the
initialization process where you select the application to run for this session. Switching
between applications r equires re-i nitializing the terminal and selecting an alternative
application when prompted. On warm boots, the terminal re-initializes and reenters the same
application t hat was selec ted before t he re -initia l izatio n. On cold boots, if there are multiple
applications available, an application selection menu is presented.

Normal Power O n Techniques

There are several ways to power on a terminal. Each way lets you resume at the same location
in the application where you left off.

Note: The Series 3800 terminals alwayscheck for enough battery power for

safe operation before they will power on.

Removal From a Cradle

The terminal automatically powers on when it is removed from a cradle. While the terminal
is in the cradle, the battery is constantly being charged. I f you remo ve the t ermi n al from the
cradle but do not use it right away, press the PWR key to turn it off, or let it power off
automatically. Refer to the section Restoring Power After Automatic Shutdown.

Keyboard

Your terminal can be programmed to power on from the keyboard in one of two ways:

!

Press the PWR key only.

!

Press any key.

!

If you press the PWR key w hil e th e ter min al is in t he cra dle, the t ermi nal p ow ers on .
If you leave the termin al in the cradle and press PWR to turn the terminal o ff, it
appears to turn off; howeve r, the terminal is on very low power.

See the your applicatio n guide or the Series 3000 Application Programmer's Guide for more
information.

Real-Time C l ock

If the application program allows it, the t e rminal can be powered on by the r eal-time clock.
This lets the terminal perform unattended operations, such as an overnight communication
session.

Laser Trigge r

If the appl icat ion pr ogr am al low s, yo u can powe r on the ter mina l by pulling t he las er t ri gger.

Operating the Series 3800

Restoring Pow er After Automatic Shutdown

The terminal shuts off if you don't use it for an amount of time set by your application. Press
the PWR key or pull the trig ger to restore p o w er an d return to yo u r a pplication.

Power Off

To perform a normal power off, press the PWR key or let the terminal shut down
automatically as programmed. See your application guide or the section Restoring Power
After Automati c Shutdown for more information. Consult your system administrator if you
are unable to power off the terminal.

Forced Power Off

If pressing the PWR key does not turn off the terminal, force the power off to reduce battery
drain and preserve your data.

To force power off, press and hold the PWR key for 1 5 s ec onds, until the term inal powers down.

Restar ti ng After a Forced Power Off

When a terminal is powered off because of software or hardware failure, use the following
methods to restart:

!

Use the warm-boot procedure for a software failure.

!

When a warm boot fails, use the cold-boot procedure.

!

If a system software problem in the nonvolatile memory (NVM) occurs, see Chapter
3, Batch and Spectrum One Term inal Setup.

Note: Do not use the PWR key to restart a terminal when it was forced off

due to defective sys tem or app lication softw are in the NVM. P ressing
the PWR key causes the program to resume where it stopped, trying
to perform the same unsuccessful operation.

Entering Data

The Series 3800 Keyboard

The keyboard is used for entering data and issuing commands to the terminal. Figure 5-1
illustrates the standard 35-key keyboard; Figure 5-2 presents the 46-key keyboard.

The keys on the keyboard are distinguished as modifier keys and character keys. Because
terminal keyboards have fewer keys than PC keyboards, each character key can produce
more than the usual o ne or two characters. The four modifier keys, SHF (Shift), AL P HA,
CTRL, and FUNC, used individually or in combination, determine which character or special
funct ion the char ac ter keys produce.

Because the keyboard is programmable, your terminal may not work as described here. For
more information and illustrations of other keyboard states, see the Series 3000 Application
Programmer's Gu ide and your application guide.

Using the Keyboard

Except for during boot operations, the terminal expects the operator to press keys one at a
time. If the te rmi nal has been programmed f o r it (ERR3000 is loaded), and if two or more
keys ar e p r es s ed s i m u ltaneou sl y, the terminal indic ates a D ouble-Key error.

The ke yb oard also has an optiona lly configurable a uto-repeat fu nction. If th e application
allows, a character repeats as long as the key is held down. If the key is pressed immediately
following a modifier key, the modifier sequence affects only the first occurrence of the
character key.

Modifier Keys

The Shift, Alpha, Function, an d Control keys are modifier keys. When pressed individually
or in certain combi nation s, these keys change th e key board state and possibly the character
produced by the character key subsequently pressed.

For example:

!

Pressing <Alpha> causes numeric keys to produce letters.

!

Pressing <Alpha> affects al l succeeding character keys until <Alpha> is pres sed
again. The other modifier keys affect only the next character key.

!

Pressing <Func> followed by <Ctrl> produces Alt characters, with the same effect as
pressing the Alt key on a PC.

5-8

Operating the Series 3800

Keyb oard Speed

If your application program allows it, the characters may be set to appear faster or slower.
Refer to the Series 3000 Application Programmer's Manual for more information.

Keyboard States

The keyboard states are listed below, in the order in which they take priority:

Unshifted
Alpha
Shifted
Function
Control

Momentary and Locked States

Each keyboard state is either momentary or locked. A momentary state lasts for only the
following keystroke. A locke d state last s until th e activator key is pressed again.

Only one mom entar y state can be active at a time. Momentar y states alway s take p rior ity
ove r loc k ed st a tes . If yo u press several momentary state keys in a ro w, the system changes to
the state of the last key pressed. For example, if you press SHF, then CTRL, the terminal
enters the CONTROL state.

If you press a momentary state key twice in a row , the system enters the state and then cancels
it. For example, if you press SHF, SHF, the terminal is shifted and then immediately unshifted.

If the terminal is program med for it, th e curso r charact er displ ays an up caret (^) in the
ALPHA state and a down caret (
cursor changes. See Keyboard State Cursor Formats in Table 5-2.

When an operator ends a mo mentary state (by toggling it off or by completing the key
sequence), the system returns the keyboard to the last acti ve locked state .

The ALPHA key activates the locked state. The CTRL, SHF, and FUNC keys activate a momentary state.

Note: Pressin g t h e FUNC key does not clear the last momentary state.

Series 3800 Product Reference Guide

Scanning

Before scanning can occur, the terminal must be running an application that supports bar
code scanning. The terminal must also be programmed to scan the type of bar code you want,
such as Universal Product Code (UPC) or Code 3 of 9. For information on scanning
applications and on programming the scanner, refer to the Series 3000 ADK.

Entering Data Using the Laser Scanner

1. Pull the trigger on the terminal handle to power on the terminal and laser scanner.

2. Hold the terminal within the specified range of distance from and at a slight angle to
the bar code you wish to scan and pull the trigger.

3. Adjust the aim so that the thin, red laser beam covers the entire length of the bar
code. Do not hold the scanner directly over the bar code. The larger the bar code, the
farther away you should hold the scanner.

Wrong Right

Optimal scanning distance varies with bar code density and scanner optics, but more
combinatio ns wo rk within 4 to 10 inche s.

4. If th e decode is succe s s ful, th e scr een displays the code and the green LED flas hes.
The terminal may also beep.

Note: The procedure for your scanner may differ from the one given above.

Scanner use depends on the application.

Scanning Conside rations

Usually, scanning is a simple matter of aim, scan, and decode, and a few quick trial efforts
master it simply and intuitively. However, two important considerations can optimize any
scanning techni que — angle and range.

5-14

Operating the Series 3800

Angle

Scanning angle is important for promoting quick decodes. When laser beams reflect directly
back into the scanner from the bar code, this specular reflection can actually “blind” the
scanner.

To avoid this, scan the bar code so that the beam does not bounce directly back. But don’t
scan at too oblique an angle; the scanner needs to collect scattered reflections from the scan
to make a successful decode (refer to Figure 5-3). Practice quickly shows what tolerances to

work wi t hin.

Tilt back at slight angle.

5-15

Series 3800 Product Reference Guide

Range

Any scanning device decodes well over a particular working range — minimum and
maximum distances from the bar code. This range varies according to bar code density and
scanning device optics.

Scanning within range brings quick and constant decodes; scanning too close or too far away
preven t s d e co d es . You need to find the r ig h t wor k in g ran g e for the ba r co d es you are
scanning. The best general advice is:

!

Hold the scanner farther away for larger symbols.

!

Hold the scanner closer for symbols with bars that are close together.

!

Start scanning at a distance from the bar code, not from direct contact. If the bar
code does not readily decode, move the scanner in closer.

!

Practice quickly shows what distances to work within.

Communications

For communications with a host or printer:

1. Set up the 3860 CCM, 3865/3866 cradle(s), or PC adapter as described in
Chapter 2, Hardware Setup.

2. Place the termin al in the CCM or cradle, or attach the terminal to the PC adapte r as

When to Replace or Recharge the Ba ttery

The Series 3800 terminals provide two types of indicators to notify you when battery power
is running low: warning messages and modified cursors. These indicators may be changed or
disabled by an application.

!

LOW BATTERY - When the battery is low , the cursor changes as shown in Ta ble 6-

1. If ERR300 is loaded, the message LOW BATTERY also appears. At this level the
terminal continues to operate, but there is probably less than 1 hour of usable power
left.

Maintaining the Series 3800

Cleaning

Series 3800 terminals require a minimum amount of maintenance, and proper use and care
of the terminal will enable it to function accurately for a long time.

To clean a terminal, use a clean soft cloth dampened with wate r. Do not use abrasive paper,
cloth, or abrasive/corrosive cleaners. Wipe the entire terminal, except for the scanner
window , with the damp cloth, including the charging contacts.

Wipe the scanner window periodically with a lens tissue or other material suitable for
cleani n g optical material such as eyeglasses.

Caution

Never pour , spray, or spill any liquid on any part of the terminal, particularly
the s canner or scan element components.

Storage

If the terminal will not be used for a while, store it in a cool, dry place, away from dust. For
the best protection, repack the terminal in the original shipping container for storage.

Caution

If you remove the pr imary batte ry, the terminal maintains memory contents
for at least 15 minutes. T o prevent loss of programs and data, transmit them
to a host computer before removing the primary batteries for longer than 15
minutes.

When you remove the Series 3800 terminal from storage without the battery pack, reset the
real time clock. Refer to the Series 3000 Application Programmer’s Reference Manual or
