1.1 Reading Bar Codes

Turn on the BHT power, bring the bar-code reading window to the bar code to be
scanned, and press the trigger switch. The BHT emits a laser light to scan the bar
code.

When the BHT has read the bar code successfully, the indicator LED will illuminate in
green.

* The trigger switch function is

assigned to both of the M3 and
M4 keys by default.

• If the BHT fails to read due to specular effects or other

factors, change the scanning angle of the reading win­dow or the distance from codes as shown at right, and
try it again. (Specular effects occur when the reflec­tion of the light from the bar code becomes exces­sively strong. This can easily happen when the re­flecting surface is polished or covered with vinyl.)

• Keep the BHT at a distance from a target bar code so that the bar code comes

within approx. 90% of the laser scanning range (line length).

• The BHT can read bar codes at a maximum distance of 56 cm (22.0")** from the

bar-code reading window.

**Under the following conditions:

- Ambient illuminance: 500 x (Xenon lamp)

- Code 39

- Reflection intensity: 85% min. for white and 5% max. for black

- Minimum narrow bar width: 1.4 mm min. (55.1 mils min.)

• The bar code reading procedure may differ depending upon the application

used, so follow the application's manual.

2

Chapter 1. Quick Guide

•

Before reading bar codes, clean those labels if stained.

•

Avoid using the BHT in direct sunlight. The BHT might fail to read correctly.

•

To read bar codes on curved surfaces, apply the BHT to the target bar code so that the
code comes to the center of the scanning range indicated by the laser beam.

•

When you pull the bar-code reading window away from bar codes, the actual
scanning range will become narrower than the range covered by the laser beam.

• Do not use the BHT in the vicinity of personal or amateur radio equipment. The
BHT may malfunction.

• Do not use the BHT near a magnetic body (e.g., equipment that generates a
magnetic field). Doing so will deflect the optical axis of the laser light, resulting
in scanning failure or machine failure.

• If the BHT has been stored in a hot (50˚C to 60˚C, 122˚F to 140˚F) and humid
place, allow it to sit at room temperature and humidity for at least one day before
use. Using the BHT with its inside being hot will fail to scan or result in a
machine failure.

the ENT key.

For example, to enter the number "120," press the 1 , 2 and 0 keys and then press
the ENT key.

If you key in any wrong value, press the C key or BS key ( SF + C keys) and then
enter the correct one.

■ Selecting Tasks

If the LCD shows the selection items (xxx) prefixed by numerals (e.g., 1: xxx, 2: xxx),
use the numerical keys to select a desired item and press the ENT key to execute.

If a YES/NO screen (e.g., 1: YES, 2: NO) appears, press the 1 key for YES response and
2 key for NO response.

■ Entering Alphabetic Characters

The BHT supports the alphabet entry function which allows you to enter alphabetic
characters, space, and symbols from the keypad during execution of a user program.

1.5 Transferring Data

■ Using radio link (BHT-7500S/7500W only)

Using radio waves, the BHT-7500S/7500W may transfer data to an access point in a
spread-spectrum communications system.

If there are too many communications errors, first make sure that the BHT points
directly at an access point because the 2.4-GHz band requires a more or less
straight line path.

Host computer

Access point

For data transfer using radio link, it is necessary to configure a wireless local area
network (wireless LAN) connecting the BHT-7500S/7500W and access points.

Using infrared rays, the BHT may transfer data directly to the host computer equipped
with an IrDA interface port and other IrDA-compliant devices.

•Make sure that there is no obstruction in the light path between the BHT and any
target stations. In infrared communication, you need to keep the BHT and any
target stations within the effective infrared radiation range, usually 10 to 80 cm
(3.94 to 31.50").

• Shield the IrDA interface from direct sunlight, intense overhead lighting (in­verter-driven fluorescent lighting, in particular), and other potential sources of
infrared radiation. Sources to watch out for include remote control units for
television sets and the like.

■ CU-7000 and RS-232C Interface Cable (option)

The CU-7000 is an IrDA-compliant communications unit which is required when your
host computer is not equipped with an IrDA interface port. The CU-7000 exchanges
data and programs with the BHT optically, and with the host computer via the RS-232C
interface cable.

You may directly connect two BHTs with each other by using a commercially available
metal cable having 3-pole mini stereo plugs (as a direct-connect interface cable). You
also connect the BHT directly with the host computer or with the modem by using the
direct-connect interface cable compatible with the target equipment. (NOTE: The
direct-connect interface port of the BHT is not designed to stand frequent connecting/
disconnecting. You are, therefore, recommended to use the CU-7000 where you
expect to do a lot of connecting and disconnecting of the BHT to/from a host com­puter.)

■ BHT-BASIC Compiler (option)

This Compiler compiles a source program written in BHT-BASIC by an editor of the
host computer running the MS-DOS, into the object program (user program) which
can be used in the BHT. The compiled and linked program file is named "XXX.PD3."
(XXX: File name you can set arbitrarily under the MS-DOS rules) You should down­load it to the BHT by using Ir-Transfer Utility C/Ir-Transfer Utility E/Transfer Utility.

■ Ir-Transfer Utility C (option)

Running on the host computer, this utility transfers files between the BHT and the host
computer. For its file transfer control procedure, the utility uses the BHT-Ir protocol.
(For the details about the BHT-Ir protocol, refer to Chapter 3, Subsection 3.5.2.)

To transfer files under any of the following conditions, use Ir-Transfer Utility C:

- At transmission speeds of 115200 or 57600 bps (This may be impossible de­pending upon the host computer type.)

- When the BHT is placed on the CU-7000

- Via the direct-connect interface of the BHT

■ Ir-Transfer Utility E (option)

Running on the host computer, this utility transfers files between the BHT and the host
computer. For its file transfer control procedure, the utility uses the BHT-Ir protocol.
(For the details about the BHT-Ir protocol, refer to Chapter 3, Subsection 3.5.2.)

To transfer files under any of the following conditions, use Ir-Transfer Utility E:

- Via an external IR transceiver

- Via an IR port integrated in a computer

■ JIS Level 1 and Level 2 Font Files

These files contain font data required for displaying Kanji characters on the LCD.

The BHT can display the Kanji characters not only in the conventional standard-size
font (16 dots wide by 16 dots high) but also in the small-size font (12 dots wide by 12
dots high) in application programs. It can also display the double-width Kanji charac­ters of those 16-dot and 12-dot fonts in application programs.

If you do not need to display Kanji characters, you may delete these JIS font files.
After deletion, the memory area which was occupied by these files can be used as a
user area. For the deleting procedure, refer to Section 2.4, "Initializing the BHT
System" or Subsection 2.5.3, "[ 9 ] Deleting Files."

The names of the JIS font files are:

FNT16J1.FN3 (JIS Level 1 font, 16-dot)
FNT16J2.FN3 (JIS Level 2 font, 16-dot)
FNT12J1.FN3 (JIS Level 1 font, 12-dot)
FNT12J2.FN3 (JIS Level 2 font, 12-dot)

■ User Programs

You can develop application programs to meet individual job requirements by using

the BHT-BASIC Compiler. To download those user programs to the BHT, use Ir­Transfer Utility C/Ir-Transfer Utility E/Transfer Utility.

2.3 Preparation

2.3.1 Setting-up 1: Loading the Battery Cartridge

Before the first use of the BHT, be sure to load the battery cartridge as shown below.
The battery cartridge is not loaded in the BHT when shipped from the factory.

(1) Charge the rechargeable battery cartridge. (Refer to Section 5.5.)

To use the dry battery cartridge in the BHT, set two dry cells into the cartridge.
(Refer to the "Dry Battery Cartridge User's Manual" that comes with the dry
battery cartridge.)

Use the dry battery cartridge as a spare of the rechargeable battery cartridge.
The run time of the dry battery cartridge loaded with new dry cells is shorter
than that of the fully-charged rechargeable battery cartridge. Some models
cannot operate on a dry battery cartridge.

(2) Turn the BHT upside down.

(3) As shown below, slide the battery cartridge into the BHT until it clicks into place.

(To remove it, press the release button after making sure that the BHT power is
off.)

cause battery-rupture or leakage of battery fluid,
resulting in a fire or bodily injury.

• Do not carry or store the battery cartridge to­gether with metallic ball-point pens, necklaces,
coins, hairpins, etc.

Doing so could short-circuit the terminal pins,
causing the batteries to rupture or the battery
fluid to leak, resulting in a fire or bodily injury.

• Avoid dropping the battery cartridge or letting
it undergo any shock or impact.

Doing so could cause the batteries to break,
generate heat, rupture or burn.

• Never charge the rechargeable battery cartridge
where any inflammable gases may be emitted;
doing so could cause fire.

• Do not use batteries or power sources other
than the specified ones; doing so could gener­ate heat or cause malfunction.

17

• Never charge the dry battery cartridge.

• The BHT has an integrated backup power source which backs up the memory and
calendar clock in the BHT when no battery cartridge is loaded or the voltage level
of the battery cartridge drops below the specified level. The backup power source
is automatically charged by the battery cartridge.

When you first load the battery cartridge after purchase or you load it after leaving
the BHT unused for a long time, do not remove the battery cartridge for 10
minutes or more after that loading. This is for charging the memory backup
source integrated in the BHT.

• Be sure to turn the BHT off before battery replacement. Replace the battery
cartridge quickly. Load a charged battery cartridge within 3 minutes from the
removal of the cartridge to avoid data loss.

After battery replacement, turn the BHT on and check its operation.

• If you leave the BHT with no battery cartridge loaded for a long time, the memory
contents will no longer be backed up so that the message "Contact your adminis­trator. Note the error number. (XXXX)" or "Set the current date and time." may
appear on the LCD.

If you will not be using the BHT for a long time, follow the instructions given in
Subsection 2.3.6, "Battery Replacement Notes."

•When disposing of the battery cartridge, cover the terminal pins with vinyl tape to
prevent short-circuit.

• Avoid storing the rechargeable battery cartridge in a hot place. The battery
capacity may be decreased.

• Do not touch the charge terminals of the rechargeable battery cartridge by hand or
stain those terminals. Doing so could result in a charging failure.

Black-and-white inverted label reading function (INVERT)

This function makes it possible to read white bars on a black background.

Activating this function might increase the frequency of bar-code reading errors.
This function can usually be set to OFF.

DECODE LEVEL

You may set the decode level. Decreasing the level value increases the bar-code
reading efficiency, but the BHT might misread low-quality bar codes (split or stained).
To the contrary, increasing the level value decreases the bar-code reading efficiency,
but it will diminish the possibility of misreading.

The setting range of the level value is from 1 to 9 and the default is 4.

58

Chapter 2. Getting Started the BHT and System Mode

Minimum number of digits to be read for ITF, STF, or Codabar (MINIMUM
DIGITS)

You may set the minimum number of digits to be read for ITF, STF, and Codabar.
Setting a small number of digits increases the frequency of digit-missing reading or
misreading depending upon how to scan bar codes or the quality of bar codes. On the
other hand, setting a large number will diminish the possibility of those errors.

The setting range is from 2 to 20 for ITF, from 1 to 20 for STF, and from 3 to 20 for
Codabar. The default is 4 for ITF and Codabar, and 2 for STF.

Magic keys

The M3 and M4 keys are assigned the trigger switch function by default. You can
make them function as the SF key, ENT key, or backlight function on/off key.

If you define the M1 key as the backlight function on/off key, pressing the M1 key
activates or deactivates the backlight function.

In user programs, a string data can also be assigned to these magic keys.

The backlight function on/off key can be assigned only to any one of M1 through

M4 keys. The key defined more recently will act as the backlight function on/off

key and one defined earlier will be ignored.
That is, if you define the M1 and M2 keys as the backlight function on/off key in

this order, the M2 key will work as the backlight function on/off key and the M1
key's entry will be ignored.
