A Synapse Adapter Cable is required when connecting the LS 1004 to any of these hosts using
Synapse. See the instructions packed with the appropriate Synapse cable.
This chapter covers the techniques involved in scanning bar codes. Included are specific
instructions on how to hold the scanner at the appropriate angle to ensure an accurate
decode.
Scanning with the LS 1004
1. Make sure all connections are secure.
2. Aim the scanner away from you and press the trigger. When you press the trigger, the
scanning beam is energized for approximately 1 second (default).
3. Make sure the symbol you want to scan is within the scanning range. See the LS 1004
Decode Zone diagram on page 3-6.
Aim and press the trigger. On the LS 1004, if you use the scanner in default Low
Power operating mode, the DECODE LED remains on until power down (maximum
of 1 second). If the unit is programmed for Continuous power operating mode, the
DECODE LED stays on until the next trigger pull.
The scanner has read the symbol when:
!
You hear a short, high tone beep (if the beeper is enabled).
!
The DECODE LED lights.
2-3
LS 1004 Product Reference Guide
Aiming
Scan the Entire Symbol
!
Your scan beam must cross every bar and space on the symbol.
!
The larger the symbol, the farther away you should hold the scanner.
!
Hold the scanner closer for symbols with bars that are close together.
!
A short, high tone beep indicates a good decode.
RIGHT
012345
WRONG
012345
Hold at an Angle
Do not hold the scanner directly over the bar code. Laser light reflecting directly back into
the scanner 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”.
2-4
Scanning
You can tilt the scanner up to 65° forward or back and achieve a successful decode. Simple
practice quickly shows what tolerances to work within.
This chapter covers the suggested maintenance of the LS 1004 scanner, as well as the technical
specifications, available accessories, pinouts, and beeper definitions.
Maintaining the LS 1004 Scanner
Battery Box Operation
When using the LS 1000 Series with a battery box, you can use either an alkaline battery
(recommended), or a nickel-cadmium rechargeable battery. Low power is signalled by 4
short, high-tone beeps, coupled with scanning interruptions. If this occurs, change or
recharge the battery as soon as possible. For battery box operation:
1. Insert a 9-volt battery into the battery box.
2. Plug the scanner’s 9-pin connector at the end of the coil cord into the end of the
battery box.
3. An output cable from the battery box connects the LS 1004 to the host device.
Connect one end of this cable to the battery box and the other to the appropriate
port on the host device.
Note: Not all applications require a power supply or battery box. The
output cable depends on the wand being replaced.
Changing the Battery
1. Disconnect the battery box.
2. To open the battery box, push up on the flanges at one end of the pack.
3. Remove the old battery.
4. Insert the new or recharged 9-volt battery into the battery box. Match the
positive (+) and negative (-) terminals on the battery with the corresponding
terminals in the battery box.
3-3

In this example, assume you want to program the scanner for all default settings except for
two parameters, DECODE UPC ONLY and INTERCHARACTER DELAY.
Since you want to keep the majority of the default settings, scan the SET ALL DEFAULTS bar
code. The default for DECODE UPC ONLY is DISABLED, but in this example, you need it

enabled. To do this, scan the DECODE UPC ONLY ENABLE bar code. You’ll hear hi/lo/hi/
low warble. The warble sound indicates that the scanner has been successfully programmed
for the selected parameter. Other beeper indications are listed in Chapter 3.
The default for INTERCHARACTER DELAY is 0 msec, but you need it set to 2 msec. To
program the scanner for a 2msec intercharacter delay, scan the bar codes listed below. This
sequence includes a two-digit entry; single-digit entries require a leading zero.

Errors While Scanning
Don’t worry if you make an error during a scanning sequence. If you’re scanning a multi-step
sequence, scanning CANCEL removes you from that sequence so that you can start again.
Otherwise, simply scan the single correct bar code for the desired parameter.

UPC/EAN Security Level
The scanner offers four levels of decode security for UPC/EAN bar codes. Increasing levels of
security are provided for decreasing levels of bar code quality. There is an inverse relationship
between security and scanner aggressiveness, so be sure to choose only that level of security
necessary for any given application.
Security Level 0 - This is the default setting which allows the scanner to operate in its most
aggressive state, while providing sufficient security in decoding in spec UPC/EAN bar codes.
Security Level 1 - As bar code quality levels diminish, certain characters become prone to misdecodes before others (i.e., 1, 2, 7, 8). If you are experiencing mis-decodes of poorly printed
bar codes, and the mis-decodes are limited to these characters, select this security level.
Security Level 2 - If you are experiencing mis-decodes on poorly printed bar codes, and the

The ACK/NAK option checks the success or failure of transmission. The scanner
expects one of the following host responses after a data transmission:
<ACK> acknowledges a valid and successful transmission.
<NAK> indicates a problem with the transmission.
Whenever a NAK is received, the unit retransmits the same data and awaits an ACK/
NAK response. After three unsuccessful attempts to transmit the same data, the
scanner aborts any further communication attempts of that message.

ENQ ONLY
The ENQ option needs the host to request data before it is transmitted to the host.
This ensures that data transmission occurs only when the host is ready to receive.
When you select the wait for ENQ option, the scanner waits for an ENQ from the
host before it transmits data; otherwise, the unit transmits data without waiting for
