RJ-11 Port

Figure 2-9. RJ-11 Internal Modem Connection

Some cradles use an optional internal modem that communicates at rates of up to 14,400 bps (with v.32 bit data compression). It can be connected directly to a telephone line through the RJ-11 port shown in Figure 2-9.

The four-slot cradle does not have an internal modem.

Note:

To connect the internal modem:

1. Connect the phone cord into the RJ-11 port on the back of the cradle.

2. Connect the other end of the phone cord into the wall phone jack.

Caution

When connecting the internal modem to the phone line, always connect the phone line to the cradle first, then to the wall phone jack. When removing the connection, always remove the telephone line from the wall phone jack, then remove from the cradle.

There are specific firmware settings which are used to configure the modem’s hardware and software for proper operation and regulatory compliance. The terminal’s application can control these settings and enable you to view and amend the settings for country/region, pulse/tone dialing, or repeat dial timing. Incorrectly defining these settings can lead to illegal use of the modem and can create unreliable operation. The application developer should consult the Series 3000 Application Programmer’s Reference Manual for correct settings.

2-9

PDT 6800 Series Product Reference Guide

Connecting to the Telephone Network

A compliant telephone cord is required with an RJ-11 plug connection to the modem, terminated with an appropriate and correctly wired local telecom connector compatible with the telephone network. Such a cable may be obtained from your local supplier. Alternately, compliant RJ-11 plugs to RJ-11 plug cables may be used with a range of adapters for locations such as Europe.

Connecting the CRD 38/6866 to Other Cradles

Up to twenty-four CRD 38/6866 cradles can be connected in a series using an RS-232 intercradle cable (p/n 60427-00-00) between each cradle.

Caution

Each cradle must have its own power supply; any other power hook-up method is unsafe.

1. Plug one end of the inter-cradle cable into the communication port located on the right end of the first cradle.

2. Plug the other end of the inter-cradle cable into the communication port located below the power connector on the left end of the second cradle.

Communications

For terminals being used in a direct communications (batch) environment 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 through the PC Adapter.

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

Programs are stored in the terminal’s nonvolatile memory (NVM), also called the application EEPROM.

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

Application Programmer's Manual.

Other software may be used in place of the SENDHEX program.

Downloading the Program

To download the program, initiate the communications software on the host computer and terminal as described in the following sections.

Note: To cancel communications at any time during the session, press

CLEAR on the terminal. The session stops immediately.

Communications parameters specified on the host and the terminal must match. These parameters typically are:

38400 bps 7-bit parity Odd parity Xon/Xoff flow control

To program the EEPROM, the terminal must be connected to the host through a cradle, CCM 38/6860, or PC Adapter with PIM.

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 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 Spectrum24 Setup and Utilities Reference Guide p/n 72-50795-01 for more information). With 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 (for example, 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

4-1

Series 6800 Product Reference Guide

operation. The software installation or application software takes care of write/read mode switching for you.

Standard Spectrum24 Software

The terminal comes with the system software installed, including:

Spectrum24 radio drivers

TCP/IP software

configuration files

various 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 Spectrum24 Network Terminal Technical Reference Guide (p/n 70-20193-XX) for more information on the Spectrum24 RF network, SLAODI.COM, the Symbol-provided ODI driver, and the configuration file setups required for various platforms.

PDT 6800 Series Product Reference Guide

Powering the Terminal On

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 PDT 6800 Series terminal always checks for enough battery

power for safe operation before it powers on.

Removing Terminal From a Cradle

The terminal automatically powers on when it is removed from a cradle. While the terminal is in the cradle, the NiCd 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 on page 53.

Note: The Lithium Ion battery is charged in the UBC 2000 battery adapter

p/n 21-32665-24, not in the cradle.

Keyboard

Your terminal can be programmed to power on from the keyboard by:

Pressing the PWR key only

Pressing any key.

If 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, but is on very low power.

See the Series 3000 Application Programmer's Guide for more information on programming your keyboard.

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.

5-2

Operating the PDT 6800 Series

Laser Trigger

If the application program allows, you can power on the terminal by pulling the trigger.

Restoring Power After Automatic Shutdown

The terminal shuts off if you do not 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.

Powering the Terminal 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.

Forcing 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:

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 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.

5-3

PDT 6800 Series Product Reference Guide

Booting the Terminal

Powering the terminal on does not boot the system or initialize the program or data. To initialize the terminal, perform either a warm boot or cold boot.

Warm Boot

A warm boot resets the operating system while preserving the program and data on the RAM disk. This process is similar to pressing the <Ctrl+Alt+Del> keys on a PC, except that it does not clear the system’s memory. To perform a warm boot:

For the 35-Key terminal:

" Power the terminal off " Press and hold <F> and <J> " Press and release <PWR> " Release <F> and <J>.

For the 46-Key terminal:

" Power the terminal off " Press and hold <4> and <5> " Press and release <PWR> " Release <4> and <5>.

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.BAT commands. If this warm boot procedure fails to restart the terminal, use the Cold Boot procedure.

Cold Boot

A cold boot fully resets the system and clears memory, including the RAM disk. Any programs and data stored in memory or on the RAM disk are deleted. Nonvolatile memory (NVM - the Application EEPROM) is not affected. 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.

5-4

Operating the PDT 6800 Series

To perform a cold boot:

For the 35-Key terminal:

" Power the terminal off " Press and hold <SPACE>, <FUNC>, and Up Arrow " Press and release <PWR> " Release <SPACE>, <FUNC>, and Up Arrow.

For the 46-Key terminal:

" Power the terminal off " Press and hold <A>, , and <D> " Press and release <PWR> " Release <A>, , and <D>.

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.

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

Publications on page x.

The backlight 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 Series 3000 Application Programmer's Guide for more information.

PDT 6800 Series Keyboard

The keyboard is used for entering data and issuing commands to the terminal. Figure 5-1 and Figure 5-2 illustrate the standard 35-key and 46-key keyboards respectively. 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 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.

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 terminal’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.

5-9

PDT 6800 Series Product Reference Guide

To cancel the effect of a modifier key, press it again.

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, unless changed by the application.

Unshifted Shifted Function Control

The standard cursor shapes for the keyboard states are shown in Table 6-1 on page 6-2.

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 Cursor Indicators, Table 6-1 on page 6-2.

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

The PDT 6800 has an integrated scanner which allows you to collect data by scanning 1 or 2 dimensional bar codes. See Appendix F, 2D Scanner Drivers and Applications for information on enabling the 2D scanner.

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 Application Developer’s Kit.

Scanning 1D Bar Codes

1. Pull the trigger on the handle to power on the terminal and laser scanner. The Scan LED turns red if scanning is enabled and the laser is on.

2. Point the terminal at a slight angle to the bar code and pull the trigger.

Figure 5-3. Using the Laser Scanner

In this case, try a slow “up and down” scanning motion. With the raster pattern open, move the terminal slowly down toward the bottom of the symbol, keeping the beam horizontal to the rows, then slowly back up toward the top.

Figure 5-5. Scanning Tall PDF Bar Code

The scan beam does not have to be perfectly parallel with the top and bottom of the symbol.

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.

Aiming: Hold at an Angle

Do not hold the terminal’s scan window directly over the bar code.

Laser light reflecting directly back into the scan window from the bar code is known as specular reflection. This strong light can “blind” the scanner and make decoding difficult. The area where specular reflection occurs is known as a “dead zone”.

5-14

Operating the PDT 6800 Series

You can tilt the terminal up to 55° forward or back and achieve a successful decode. Practice quickly shows what tolerances to work within.

Figure 5-6. Scanning Angle and Specular Reflection

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:

Hold the scanner farther away for larger symbols.

Move 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.

Battery Life

Battery life is affected by many factors, including

scanning

radio communications

very high or very low operating temperatures

backlighting use

battery age.

When to Replace or Recharge the Battery

The PDT 6800 Series 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 Table 6-

1 on page 6-2. If ERR3000 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.

VERY LOW - When the power is very low, the DEAD BATTERY message appears

and the system powers off. Replace or recharge the battery pack before attempting to use the terminal. If the battery is not immediately recharged or replaced, data may be lost.
