Chapter 1
The Series 68XX System
Symbol Technologies’ 68XX terminals are hand-held, battery-powered, portable data
collection devices. Data is entered from the 68XX’ s keyboard or through the integrated laser
scanner. As a remote terminal, the 68XX terminal collects and stores data that is later
uploaded to a host computer. The 6800 is a batch computer (no radio). Radio terminals
include the 6810 for use in a Spectrum One® network and the 6840 for the Spectrum24®
radio network environment.
68XX terminals use Caldera’s DR DOS™ operating system that is compatible with and
extends Microsoft® MS-DOS®. Although 68XX terminals are MS-DOS feature compatible,
they are not one hundred percent MS-DOS compatible. DR DOS provides access to a number
of commercially available programming tools. Additional programming tools are available
from Symbol for easier programming and access to special features.

Chapter 4
Spectrum24 RF Terminal Setup
Spectrum24 T erminals
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 is 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 applications from the same terminal (refer to the section Multiple Applications on
the Same T erminal for more information). W ith version 3.03 or later of the system software
(LWP.HEX), the terminal can also run diagnostic tools.
Accessing the Flash Disk
The flash disk is accessed through a driver, FLASHDSK.SYS, which makes the flash disk
appear to a program as another disk drive (E:). The drive has characteristics of fast reading
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. It is important to note that because of the slow writing time (3-4 seconds), writing
files during a power interruption (low battery, dead battery, suspend, power off, or power
failure) could corrupt the disk. Be sure to only write data to the disk with the terminal
connected to external power or with the battery fully charged to avoid problems. To avoid
overwriting the flash disk by mistake, the flash disk is set to read-only mode for normal
operation.

Series 6800 Product Reference Guide
Standard Spectrum24 Software
The 6840 comes with the system software installed, including:
tSpectrum24 radio drivers
tTCP/IP software
tconfiguration files
tvarious utilities.
A BIOS of version 3.08 or later is required.
The default files cover most expected installations/initializations with minor changes as
detailed in this chapter.
If your requirements are more advanced, refer to the SLASAP.COM 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 6840 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 6840 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 Initializing the
Series.
T wo protocols are defined for the IP address allocation on the network: BOOTP 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.

Updating System Software on Flash Disk
Updating the LWP hex image means loading the new system files on the flash disk using the
SENDHEX utility on a PC. It is possible to perform this update on multiple terminals in a
cradle at one time, with each terminal running Program Loader from Command Mode.
Note: The 6840 is shipped with the LWP hex file installed. Use this
procedure ONLY:
• to load a new version of LWP greater than 3.03
• if you experience serious difficulties
• if you are so directed by Symbol’s Technical Support staff.
Option: Using _L.BAT to Update System Software
If the 6840 terminal contains a LWP hex file of version 3.03, you can follow the instructions
for installing application software on the flash disk using _L.BAT through step 6, when the
terminal is reinitialized. Proceed to step 6 of this procedure at that point.
Note: Be sure, when entering the SENDHEX command on the PC, to issue
the command from the directory where the hex file (LWP.HEX) is
stored.

Spectrum24 RF Terminal Setup
Compatibility Issues When Updating
While the order in which software packages are loaded is not important, we recommend
loading the system files, LWP.HEX, 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 system files allows the old applications to run with updated
system software.
Note: Some configuration changes may be required.
Complications: Naming Applications
In versions of LWP.HEX for flash disk terminals prior to version 3.03, parameters were
defined in NET.CFG to specify the applications that would run on the terminal. If only one
application was used and no applications 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 potential problem, if ALL the software on the flash disk is being replaced in
the update, we recommend reformatting the flash disk using FLSHFMT . Reformatting deletes
ALL the files on the flash disk and eliminates this duplication.
Note: DO NOT run the FLSHFMT utility unless all the HEX files,
including LWP.HEX, are available to recreate the flash disk file
system.
Complications: System Parameters
In flash disk terminals with a LWP.HEX version prior 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.
4-19
Page 63
Series 6800 Product Reference Guide
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 Applications on the Same Terminal
The system files (from LWP.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 installing more than one application on a single 6840. 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 RAM
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 forms
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 contained in the LWP.HEX have the RAM disk
defined as 80 KB.
It is possible with multiple applications to have applications 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 multiple applications are installed on the 6840, a menu is presented during the initialization
process where you select the application to run for this session. Switching between
applications requires re-initializing the terminal and selecting an alternative application when
prompted. On warm boots, the terminal re-initializes and reenters the same application that
was selected before the re-initialization. On cold boots, if there are multiple applications
available, an application selection menu is presented.

Normal Power On 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 68XX terminals always check for enough battery power
for safe operation before they 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. If you remove the terminal 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:
tPress the PWR key only.
tPress any key.
tIf you press the PWR key while the terminal is in the cradle, the terminal powers on.
If you leave the terminal in the cradle and press PWR to turn the terminal off, it
appears to turn off; however, the terminal is on very low power.
See the your application guide or the Series 3000 Application Programmer's Guide for more
information.
Real-Time Clock
If the application program allows it, the terminal can be powered on by the real-time clock.
This lets the terminal perform unattended operations, such as an overnight communication
session.
Laser Trigger
If the application program allows, you can power on the terminal by pulling the laser trigger.
5-2
Page 66
Operating the Series 68XX
Restoring Power After Automatic Shutdo wn
The terminal shuts off if you don't use it for an amount of time set by your application. Press
the PWR key or press the trigger to restore power and return to your application.
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 Automatic 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 15 seconds, until the terminal powers
down.
Restarting After a Forced Power Off
When a terminal is powered off because of software or hardware failure, use the following
methods to restart:
tUse the warm-boot procedure for a software failure.
tWhen a warm boot fails, use the cold-boot procedure.
tIf a system software problem in the nonvolatile memory (NVM) occurs, see
Chapter 3, Batch and Spectrum One Terminal Setup.
Note: Do not use the PWR key to restart a terminal when it was forced off
due to defective system or application software in the NVM. Pressing
the PWR key causes the program to resume where it stopped, trying
to perform the same unsuccessful operation.

Booting a Series 68XX
Warm Boot
A warm boot resets the operating system while preserving the RAM disk.
To perform a warm boot:
1. Power off the Series 68XX.
2. Press and hold the 4 and 5 keys.
3. Press and release the PWR key.
4. Release the 4 and 5 keys.
The terminal displays configuration information, copyright, RAM size, and expanded
memory RAM size. Other information displayed depends on the operating system, installed
device drivers, and AUTOEXEC.BA T commands. If this warm-boot procedure fails to restart
the terminal, use the cold-boot procedure.
Cold Boot
A cold boot resets the BIOS and operating system; it erases and recreates the RAM disk. If
the cold-boot procedure fails to restart the terminal, see Chapter 7, Error Recovery and
Troubleshooting.
Caution
This procedure permanently erases all data and software in the terminal unless they reside in NVM. Contents of RAM are lost.
To perform a system cold boot:
1. Power off the Series 68XX.
2. Press and hold the A, B, and D keys.
3. Press and release the PWR key.
4. Release the A, B, and D keys.
The terminal displays version information, copyright, RAM size, and installed expanded
memory RAM size. Other information displayed depends on the operating system, installed
device drivers, and AUTOEXEC.BAT commands.

Operating the Series 68XX
Cold-Boot Failure
During a cold boot, the system briefly displays a status line for each driver as it loads in the
format:
0: Driver#.##
The line shows a status value, usually 0, followed by the name and version number of the
driver. If the system halts at one of these lines and displays a status value other than 0, the
displayed device driver failed to load properly.
If such a failure occurs, try cold booting the terminal again. If this does not solve the problem,
call the Symbol Support Center.
More troubleshooting information is provided in the publications listed in Related Documentation at the beginning of this manual.
Boot to Command Mode
Command Mode provides functions for:
tRunning the Self-Test program to verify that the hardware is operating properly
(refer to Chapter 7, Error Recovery and Troubleshooting).
tPerforming a Memory Transfer to upload data from a terminal to a host system
(refer to Chapter 7, Error Recovery and Troubleshooting).
tPerforming a Program Download to transfer an application from the host to a
terminal (refer to Chapter 3, Batch and Spectrum One Terminal Setup).
To boot to Command Mode:
1. Power the Series 68XX off.
2. Press and hold down the F and I keys.
3. Press and release the PWR key.
4. Release the F and I keys.

Series 68XX Product Reference Guide
Adjusting the Screen Contrast
Display Contrast
The screen’s contrast is adjustable to eight levels, making the display more readable in
different lighting conditions, and at various temperatures.
The backlight illuminates the display in dimly lit areas.
To turn the back light on or off, press FUNC then L, or use the key sequence listed in your
application guide. The back light turns off automatically when the terminal is powered off or
when the terminal has not been used for an amount of time set by the application. See the
application guide for more information.
Entering Data
The Keyboard
The keyboard is used for entering data and issuing commands to the terminal. 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 one or two characters. The modifier keys, SHF (Shift), CTL, and FUNC, used
individually or in combination, determine which character or special function the character
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 Guide 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 terminal has been programmed for it (ERR3000 is loaded), and if two or more
keys are pressed simultaneously , the terminal indicates a Double-Key or Too Many Key error.
5-6
Page 70
Operating the Series 68XX
The keyboard also has an optionally configurable auto-repeat function. If the 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, and Control keys are modifier keys. When pressed individually
or in certain combinations, these keys change the keyboard state and possibly the character
produced by the character key subsequently pressed. Refer to Table 5-1 for a list of the
68XX’s special keys.
For example, pressing <Func> followed by <Ctrl> produces Alt characters, with the same
effect as pressing the Alt key on a PC.
Keyboard 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
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 locked state lasts until the activator key is pressed again.
Only one momentary state can be active at a time. Momentary states always take priority
over locked states. If you press several momentary state keys in a row , 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.
The CTRL, SHF, and FUNC keys activate a momentary 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.
When batteries are low , the cursor changes. See Keyboard State Cursor Formats in Table 5-2.
5-7
Page 71
Series 68XX Product Reference Guide
When an operator ends a momentary state (by toggling it off or by completing the key
sequence), the system returns the keyboard to the last active locked state.
Note: Pressing the FUNC key does not clear the last momentary state.
However, pressing another momentary key after FUNC clears the
FUNCTION state.

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 handle to power on the 68XX and laser scanner . The Scan LED
turns red if scanning is enabled and the laser is on.
2. Point the 68XX at a slight angle to the bar code and pull the trigger.
Figure 5-2. Scanning with the 68XX
3. Ensure that the scan beam crosses all bars and spaces on the bar code symbol, as
shown below. Do not hold the scanner directly over the bar code.
WrongRight
Optimal scanning distance varies with bar code density and scanner optics, but more
combinations work within 4 to 10 inches.
4. If the decode is successful, the screen displays the code and the Scan LED flashes red.
The terminal may also beep.
5-11
Page 75
Series 68XX Product Reference Guide
Note: The procedure for your scanner may differ from the one given above.
Scanner use depends on the application.
Scanning Considerations
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 technique — angle and range.
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 within.
5-12
Figure 5-3. Scanning Angle and Specular Reflection
Page 76
Operating the Series 68XX
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
prevents decodes. You need to find the right working range for the bar codes you are
scanning. The best general advice is:
tHold the scanner farther away for larger symbols.
tHold the scanner closer for symbols with bars that are close together.
tStart 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.

When to Replace or Recharge the Battery
The Series 68XX 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.
tLOW BA TTERY - When the battery is low, the cursor changes as shown in Table 6-
1. If ERR300 is loaded, the message LOW BA TTERY also appears. At this level the
terminal continues to operate, but there is probably less than 1 hour of usable power
left.
tVERY LOW - When the power is very low, the DEAD BATTERY message appears
and the system powers off. Replace an alkaline battery or recharge a NiCd battery
before attempting to use the terminal. If the battery is not immediately recharged or
replaced, data may be lost.

Cleaning
Series 68XX 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 water. 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
cleaning optical material such as eyeglasses.
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 primary battery , 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

Error Recovery and Troubleshooting
Memory Transfer Program
Command Mode includes a memory transfer utility that transfers data from a terminal to a
host PC for program troubleshooting. Programmers can analyze an application using tools
provided in the Series 3000 Application Development Kit and described in the Series 3000 Application Programmer’s Reference Manual.
Hardware Setup
1. Turn off the terminal and host PC. Disconnect or unplug the cradle, if used.
Caution
Always power off the terminal before attaching or removing cables or
adapters.
2. Connect an RS-232 null modem cable to the PC's serial port.
3. Connect the other end of the cable to the cradle’s communication port.
4. Connect the cradle to a power source.
5. Place the terminal in the cradle.
6. Power on the host PC.
Set Communications Parameters
Host
1. Start the communications program, such as DMX or RCVHEX.EXE from the Series
3000 Application Development Kit.
2. Set up the host communication parameters (these parameters must match the
terminal’s parameters). Refer to the data transfer program's operator's manual for
details.
Terminal
1. Boot the terminal to Command Mode (refer to Chapter 5, Operating the Series
68XX for the appropriate key sequence).

Scanning Problems
What If...
Nothing happens when you follow the operating instructions?
tCheck the system power.
tV erify that the scanner is programmed to read the symbology you are trying to read.
tTry scanning a test symbol of the symbology you are trying to read.
tCheck the bar code to ensure that it is not defaced. A defaced bar code may not be
readable.
tCheck to see that you are scanning from the proper distance.
Your terminal operates but scanned data is not displayed correctly?
tCheck the system power.
tCheck that the communications parameters (baud rate, parity , stop bits, etc.) are set
properly for the receiving device.
The laser does not activate?
tYou may have exceeded the allowable amount of scanning activity within the limits
of your laser class of operation; in this case, wait for a short interval before scanning
again.
tYou may be scanning in an inappropriately hot environment. If so, remove the
equipment from the environment or allow the laser to cool down.
