Description of the scanner
The 4685-L0D scanner delivers high performance, either as a small, fixed scanner
or as a targeted handheld scanner. Its innovative design maximizes productivity
and minimizes operator stress, strain, and fatigue.
The 4685-L0D scanner's compact size uses very little counter space. The scanner
is designed for durability, long life, and low maintenance. With three scanning
options—fixed, portable, and handheld—the scanner is versatile and flexible. You
can bring small items to it, or take it to large bulky items.
Visible laser diode (VLD) technology, coupled with improved decoding software,
contribute to a high percentage of first-pass reading and thus to operator efficiency.
Many labels that were difficult to read with earlier scanners, such as those printed
too heavily or too lightly, can now be read on the first pass. The Edge** software
increase the ability to read truncated or torn bar codes.
The VLD technology uses little power and generates little heat, and thus contributes
to the durability of the scanner. The sleep mode which turns off the scanner when
it is not in use, contributes further.
Product overview
The 4685-L0D scanner is designed primarily for presentation and sweep scanning
from a fixed position (Figure 1-1). It can also be removed from the stand for use
as a portable multi-line scanner (Figure 1-2) or a single-line handheld scanner
(Figure 1-3). Use the 4685-L0D scanner's front scan window for presentation and
sweep scanning, and the rear scan window for targeted handheld scanning.

The scanner should be connected to your POS terminal, with the POS interface
cable supplied with the scanner. The cable should be connected to one of the
following ports:
M/T 4694 POS terminal directly: Port 9/E or 9
M/T 4614 POS terminal: Port C or D
SurePOS 700 Series (F/C 9540): Port USB
M/T 4674 POS terminal: Port scanner connector
A POS terminal that has a USB or RS-485 interface recognizes the 4685-L0D
scanner as a handheld scanner.

Chapter 3. Configuration of the 4685-L0D Scanner 3-1
Important
Before you can verify the scanner and complete the test, the POS terminal must
be correctly configured for the scanner. If it is not, configure is at this stage.
The RS-485 model and the USB model of the 4685-L0D scanner are configured by
sending commands from the POS terminal. The RS-232 model is configured by
reading programming bar codes. For information about the support programs, see
“Operating system” on page 1-6.
Note: A POS terminal that has a USB or RS-485 interface recognizes the
4685-L0D scanner as a handheld scanner.
Configurable features
This section describes the features of the scanner and the settings available for
each feature. As the scanner is shipped, each feature has a default setting, here
shown underlined and in boldface type.
Indicators for the operator
Tone (beep) heard after a correct reading of a bar code: Enabled, Disabled
Tone volume: Low, Medium, High
Double-read timeout: 400, 500, 600, 800, 1000 ms
The double-read timeout is the interval between readings of the same label.
The default time, 600 ms, is a good compromise between prevention of double
reading and the need to scan rapidly for the sake of throughput (the number of
items scanned in a minute). If you do not need high throughput, select a
longer double-read time.
Bar code decoding
Reading UPC/EAN, Code 39, Code 128, Interleaved 2 of 5: Enabled, Disabled
Reading Add-on label (P2 supplemental, P5 supplemental) and EAN/JAN
2-label: Enabled, Disabled
Minimum scans per read
Scans per read refers to the number of laser sweeps that the scanner is to make
over the bar code to achieve a correct reading. One scan is generally sufficient,
and yields the highest throughput. The choices are as follows:
UPC-A: One, Two, Three
UPC-E: One, Two, Three
Because UPC-E codes are short, the default is set at two scans to improve the
probability of correct readings.
EAN-13: One, Two, Three
EAN-8: One, Two, Three
UPC In-Store Code: One, Two, Three
Code 39, Code 128, and Interleaved 2 of 5: One, Two, Three
3-2 IBM 4685-L0D Scanner: Setup, Operation, and Service Guide
UPC codes beginning with 2 or 4 are In-Store code. These are often printed in the
store, and if the printing is substandard, the reading rate deteriorates. The
decoding algorithms for the 4685-L0D scanner can handle many of the errors commonly caused by poor printing. If you need to, you can scan each bar code two or
three times.
Bar code expansion
The same numbering system is commonly used for bar codes in UPC-E, UPC-A,
and EAN-13, and the scanner handles all these codes in the same way. The
default value for bar code expansion is Do not expand
.
Expand UPC-A to EAN-13: Expand, Do not expand
UPC-A is a twelve-digit subset of EAN-13. A UPC number can be handled as
an EAN number if a zero is added at the beginning. The scanner can add this
zero.
Expand UPC-E to UPC-A: Expand, Do not expand.
UPC-E is a short form of a UPC-A number. The scanner can expand UPC-E
data to the UPC-A format.
Expand UPC-E to EAN-13: Expand, Do not expand.
Verifying bar codes for a price check
Check the bar code to verify the 4-digit or 5-digit price: Verify 4 digits, Verify 5
digits, Do not verify.
The UPC and EAN specifications allow for a price check character to be
included in the digits encoded on in-store weight items. The 4685-L0D scanner
verifies the price check bar code, to compensate for the poor print quality often
found on labels printed in-store.
Reading JAN 2 labels
Read two JAN-13 labels with a single scan: Combine, Do not combine
Selecting Combine causes two JAN-13 labels to be combined into a pair, so
that additional information can be included in the bar code. JAN-13 prefix
numbers are programmable (up to six pairs). For example, when a pair is
given the prefix numbers 21 and 22, the scanner reads a JAN-13 label that has
the prefix number 21 only if it also reads a JAN-13 label that has the prefix
number 22. If it finds both labels, it issues the “correct reading” tone and sends
information from the two labels to the POS terminal.
.
To configure for reading two labels as a single bar code, you should make programming bar code (except the USB model). For more information, go to the
following Web site:
http://w3.apsd.yamato.ibm.com/Distribution/POSIO/indexe.htm
Chapter 3. Configuration of the 4685-L0D Scanner 3-3
Sleep mode control
To maximize the lifetime of the laser and the motor, the 4685-L0D scanner goes
into sleep mode after the scanner is left inactive for a specified period of time. You
can specify that time; the only requirement is that the timeout for the motor has to
be longer than for the laser.
Laser timeout: (5, 10, 15 minutes)
Motor timeout: (5, 15, 30, 60 minutes)
Printing the configurations (RS-485 model only)
You can have the configurations of the scanner, printed by the printer of the POS
terminal.
1 Turn on the POS terminal and load the initial program (IPL).
Note: For additional information, see Problem Determination Guide for the
operating system.
2 On the keyboard of the POS terminal, press S1, enter 91, and press S2.
The message “T0010 ENTER TEST REQUEST” appears on the POS terminal display.
3 Enter 96, and press S2.
The message “PRINTING CONFIGURATION” appears on the POS terminal
display, and the printer prints the scanner configuration.
4 To leave this mode, enter 99 from the keyboard of the POS terminal, and
press S2.
You can print the scanner configurations by use of either the reference diskette or
service diskette, depending on the type of the terminal used. To find out which
diskette you should use, see the hardware service manual for the terminal, and
follow the procedure for that diskette.

Setting up the scanner program
You can set up or change the configuration of the scanner by scanning the bar
codes provided later in this section.
Put the scanner into programming mode by scanning the Programming Switch
bar code. The green LED contradiction in terms, indicating that the scanner is in
programming mode.
Scan the programming bar code(s) for the feature you want to change. The
scanner emits three beeps to indicate that the bar code has been read and the
setting has been stored in the scanner's memory. Scan the remaining programming bar codes as required.
If a bar code scanned is not valid, the scanner emits a “chirping” (rapid beeping)
rejection tone.
After you have successfully scanned all the desired programming bar codes, leave
programming mode by scanning the Programming Switch bar code again. The
scanner resets; during the power-up sequence, it emits four beeps.
For more information, go to the following Web site:
http://www.pscnet.com/pdf/R44-1740.pdf
The green lamp shines dimly, indicating that the scanner is ready for normal operation.
Programmable rear scan line
In the standard configuration of the scanner, the single rear scan line pointer is
always on and ready for use. To have the pointer stay off until you push the
button, scan the bar codes on page 3-6. Then, pressing the button automatically
activates the scanner.
To change the settings on your scanner, use the rear scan line to scan the Switch
Label; then scan the label for the rear laser mode you want, and scan the Switch
Label again. The scanner resets and invokes the new mode of operation. This
setting is saved.

By using timeouts, you can have the scanner's laser and/or motor switch off if the
scanner isn't used for a specified period of time. This feature is included to reduce
power consumption and lengthen scanner life.
Note: Laser safety requires that the laser switch off before the motor. If you set
the motor timeout shorter than the laser timeout, the laser will switch off when the
motor times out.

Link characteristics
This section describes the following link characteristics of the RS-232 scanner interface:
Basic operating modes
Message timing
Error detection
Basic operating modes
The RS-232 scanner interface operates in any of the following modes:
Free-flow operating mode
Software-flow operating mode
Hardware-flow operating mode
Inter-character delay operating mode
Free flow
In the free-flow operating mode, the conditions are as follows:
When the scanner receives the DTR signal, it establishes a connection with a
POS terminal, and enters the ready state.
The scanner decodes the labels immediately after power on.
The scanner optionally buffers one additional label.
The scanner sends the RTS signal, and then requests that the decoded data
from the label be sent to the POS terminal.
The scanner uses the intercharacter delay that has been configured.
Free flow with timing and flow control
In this operating mode, there is no handshake capability. The operation proceeds
as follows:
The scanner decodes a label. If you have chosen beep/lamp option 1, the
scanner beeps and the lamp comes on. (For a description of the beep/lamp
function, see page 4-16) The RTS signal is issued to notify the POS terminal
that the scanner is ready to transmit data.
The scanner begins transmitting data.
As soon as the last character of the message has been transmitted, the RTS
signal is resent. If you have chosen beep/lamp option 2, the scanner beeps
and the lamp comes on.
Another label is decoded, to begin a repetition of the cycle.
For the details of the free-flow operating mode, see Figure 4-1.
Chapter 4. RS-232 Scanner interface specifications 4-5
Figure 4-1. Free-flow operating mode
4-6 IBM 4685-L0D Scanner: Setup, Operation, and Service Guide
Software-flow operating mode
In the software-flow operating mode, the conditions are as follows:
On receiving a DTR signal, the scanner establishes a connection with a POS
terminal, and then enters the ready state.
The scanner decodes the labels immediately after power-on.
The scanner buffers one additional label, if desired.
The scanner sends the RTS signal and then requests that the decoded data
from the label be sent to the POS terminal.
The POS terminal controls the transmission of the decoded data by means of
the software control handshaking characters, XON/XOFF.
The scanner uses the intercharacter delay specified in the configuration.
Software-flow operating mode with timing and flow control
The handshake timing and flow control used is XON/XOFF. The software-flow
operating mode operates as follows:
The scanner decodes a label. If you have chosen beep/lamp option 1, the
scanner beeps and the lamp comes on. (For a description of the beep/lamp
function, see page 4-16).
The RTS signals to the POS terminal that data is ready for transmission.
The scanner checks whether an XOFF flow control character has been
received from the POS terminal. If one has been received, the decoded data
from the label is not transmitted.
If no XOFF has been received, the scanner begins transmitting data. If the
scanner receives an XOFF character while transmitting data, the transmission
is suspended; it is resumed only after the scanner receives an XON character
from the POS terminal.
After the last character of the message is transmitted, the RTS signal is resent.
If you have chosen beep/lamp option 2, the scanner beeps and the lamp
comes on.
Another label is decoded, to begin a repetition of the code.
For details about the software-flow operating mode, see Figure 4-2.
Chapter 4. RS-232 Scanner interface specifications 4-7
Figure 4-2. Software-flow operating mode
4-8 IBM 4685-L0D Scanner: Setup, Operation, and Service Guide
Hardware-flow operating mode
In the hardware-flow operating mode, the conditions are as follows:
On receiving a DTR signal, the scanner establishes a connection with a POS
terminal, and then enters the ready state.
The scanner decodes the labels immediately after power-on.
The scanner buffers one additional label, if desired.
The scanner sends the RTS signal and then requests that the decoded data
from the label be sent to the POS terminal.
The POS terminal controls the transmission of the decoded data by means of
the software control handshaking characters, XON/XOFF.
The scanner applies the intercharacter delay specified in the configuration.
Hardware-flow operating mode with timing and flow control
The handshake timing and flow control used is RTS/CTS. The hardware-flow operating mode operates as follows:
The scanner decodes a label. If you have chosen beep/lamp option 1, the
scanner beeps and the lamp comes on. (For a description of that option, see
page 4-16) The RTS signal is sent to the POS terminal as a notice that the
decoded label data is ready for transmission.
The scanner monitors the CTS input signal to determine whether the POS ter-
minal is ready to receive data. If the CTS signal is active, the data decoded
f4rom the label is transmitted. If the signal is inactive no data is transmitted. If,
during data transmission, the CTS signal goes from active to inactive, the data
transmission is suspended. It is resumed only after the POS terminal resends
the CTS input signal.
After the last character is transmitted, the RTS signal is resent. If you have
chosen beep/lamp option 2, the scanner beeps and the lamp comes on.
Another label is decoded, to begin a repetition of the cycle.
For details of the hardware-flow operating mode, see Figure 4-3.

4-10 IBM 4685-L0D Scanner: Setup, Operation, and Service Guide
Intercharacter-delay operating mode
The intercharacter delay operating mode provides a means of communication
control by delaying the transmission of label data. The scanner delays the transmission of each succeeding character by a fixed, configurable amount.
For details of the intercharacter delay operating mode, see Figure 4-4, Figure 4-5,
and Figure 4-6.

The bar code has been read.
The scanner is in programming mode.
The scanner has been disabled by a command from
the host.
Scanning with the 4685-L0D scanner
With two scan windows, the 4685-L0D scanner can be easily adapted to either
fixed/portable or targeted handheld scanning. The front scan window, with its multiple scan pattern, is used for most retail items. The rear scan window emits a
single targeted scan pattern for handheld scanning of bar codes on hard-to-read or
bulky items, or to read an individual bar code among many bar codes.
Fixed-mode scanning
Fixed-mode scanning provides ease of use by reducing the need to pick up the
scanner to read a bar code. A specially designed scan pattern minimizes the need
for the operator to position the item for scanning.
The scanner stand can be adjusted forward and backwards as needed. For most
applications, the best scanning position is straight up and down. Figure 5-1 shows
the range of movement.
Optimal position for most applications
Figure 5-1. Adjustments of the scanner position
To use the scanner in fixed mode, place the scanner into the stand and make sure
it is seated securely. In this mode, the scanner can read bar codes in either the
sweep mode or the presentation mode.
Chapter 5. Operation 5-3
Sweep scanning
To perform a sweep scan, move (sweep) the product, with the bar code facing the
front window, laterally through the scan volume. AsFigure 5-2 shows, the scan
volume for fixed scanning extends about 23 cm (9 inches) in front of the scan
window.

The optimal scanning distance is at the center of the scan volume, or about 11 cm
(4.5 inches) from the window.
Figure 5-3 shows the motion of an item swept past the front scan window.

Presentation scanning
For the best performance, face the bar code towards the center of the front scan
window. Move the product with the bar code towards the scanner, as shown in
Figure 5-4.
Figure 5-4. Presentation scanning
Portable scanning
To use the 4685-L0D scanner as a portable scanner, remove it from the stand, but
do not press the trigger switch. Sweep the scanner over the bar code, using the
front scan window as in Figure 5-5.

Chapter 5. Operation 5-5
Targeted handheld scanning
With targeted handheld scanning, the operator can point the scanner instead of
lifting a heavy or bulky item that is in the customer's hands or shopping cart. A
specially designed pointer line helps the operator aim at the bar code.
The scanner's shape cradles comfortably in the operator's hand. Its weight is distributed evenly to maximize balance and minimize fatigue.
To use the 4685-L0D scanner as a targeted handheld scanner:
1 Grasp the scanner in the palm of the hand, with the thumb on or near the
trigger switch.

needs to be close to the scan window; a large one should be farther away.

To continue scanning in the targeted handheld mode, repeat step 3, placing the
pointer line on the next item's bar code, and step 4, pressing the trigger switch.
If the scanner does not give an indication of correct reading after you pass the bar
code over the window, pass the product backward over the window to try again.
If this attempt succeeds, be careful not to pass the product over the window for a
third time; to do so would cause the scanner to read the same bar code again.
Chapter 5. Operation 5-7
Bar code
If the scanner doesn't read the bar code after a few tries, go through the following
list of possible reasons why:
Make sure that no part of the package or your finger is between the bar code
and the scanner.
Make sure the scanner laser is on. If the POS terminal encounters an error, or
is timed out, the scanner is disabled.
Check the condition of the bar code on the product.
– Blots, imperfect printing, or other defects may interfere with scanning.
– A bar code on polyfilm wrapping may have gotten folded, wrinkled, or oth-
erwise deformed. Pull the wrapping to straighten out the bar code.
– Frozen or refrigerated products may be coated with frost or dew. Wipe off
any moisture with your finger or a towel.
Make sure that the scan window is clean. See “User maintenance.”
Make sure you are waiting long enough between tries. The scanner pauses
briefly after each reading, to avoid reading the same label twice if you hold it
over the window too long.
See whether the scanner has gone into sleep mode. If it is not used for the
length of time specified in the configuration, the motor and the laser are turned
off automatically, and the green indicator lamp flashes. To return the scanner
to operating mode, wave your hand over the scan window.
User maintenance
Daily maintenance: The operator can perform the following work only.
Cleaning the scan windows
Using a lint-free towel or tissue with nonabrasive ammonia-based glass cleaner.
