LG2 is a revolutionary new, bar LG2. Developed to be the rst universal reader, no other single de-
vice performs as many functions. With a cost of ownership far less than comparable systems, the
LG2 incorporates a unique dual path optical system, a 1.3 million pixel CMOS sensor, and a 400
MHz processor. This combination has created a reading system that supports:
• High density matrix barcodes and larger low density linear barcodes
• Superior working range
• High-speed omni-directional decoding
• Cordless and cabled interfaces
• Unsurpassed data rates
The LG2 sets a new benchmark for size and weight.
It is smaller and lighter than comparable systems yet
can withstand multiple drops to concrete. It is the only
product available in handheld, gun handle, and
presentation stand form factors with cabled, batch
and cordless versions. The cordless version utilizes
the latest Bluetooth™ class 1 radio with a 300 foot
operating range. The LG2 is rugged and lightweight
and the cordless version will operate for more than a
complete shift at the highest use rate. The LG2 per-
forms more than 3000 reads and transmits from a
single battery charge. The LG2 will automatically
discriminate between all major 2-D matrix and linear
barcode symbologies and features a timestamp
feature for logging data.
Whether you need a small, palm-held device or a traditional gun, LG2 was specically
developed so users may easily choose the device that best meets their needs. The LG2
is available in three (3) basic congurations:
• LG2 Cabled - USB, RS-232 or PS2 interfaces
• LG2 Batch - Store and forward device with memory and long-life battery
• LG2 Cordless - Long life battery and Bluetooth radio

1.2 - Unpacking
Remove the imager from its packing and inspect it for damage. If the scanner was damaged
during shipping, please call Opticon at [phone].
The standard LG2 unit is shipped with a USB cable interface. The unit also features a battery
blank that must be installed in the unit at all times.
Various accessories are available for the LG2.
• 3 cable options (USB, RS-232 or PS2)
• 1300 mA Lithium-Ion battery
• Class 1 Bluetooth radio with 300 foot operating range
• Clip-on pistol grip handle
• External battery charger
• CodeXML Bluetooth modem
Please keep your packing materials. The LG2 is shipped in an approved shipping container and
should be used if you ever need to return your equipment for servicing.
The LG2 utilizes digital camera technology to take a picture of a symbol. Once an image is captured,
the LG2 utilizes advanced decoding algorithms to extract data from the captured image.
The LG2 is available as a palm-held unit or users may purchase a clip-on pistol-grip handle.
The palm held unit features left and right triggers (gure 1.1). These triggers may be programmed to
perform various features. The reader is shipped with the left trigger and right trigger functioning as a
decode symbol command.
The clip-on pistol-grip handle features a trigger on the handle (gure 1.2). The two triggers on the top
of the unit also work when the handle is attached.
1.3 - Targeting and Reading Techniques
Note: The trigger on the handle attachment is light.
Squeezing to hard may damage the unit.

To read a symbol with the LG2:
1. The LG2 features omnidirectional decoding. Center the symbol in any orientation within
the laser dot aiming pattern (gure 1.3).
Note: The LG2 can read a symbol that is not centered however, the LG2 performs best
when a barcode is centered. If two (2) barcodes are with the imagers decode zone, the LG2
will decode the symbol closest to the center of the aiming dot.
2. The LG2 was developed to decode both very small 2-dimensional barcodes and larger
1-dimensional barcodes. The unit features two imagers to create an innovative dual
decode zone. The LG2 features a high speed processor and DECODES BOTH
ZONES SIMULTANEOUSLY. The unit has one imager focused on a near-eld for
smaller barcodes (optimal focal point is 4 inches) and one imager focused on a far-eld
for larger barcodes (optimal focal point 9 inches). To read smaller symbols move the LG2
closer to the symbol. To read larger barcodes move the unit farther away from the
barcode (see gure 1.4). The entire LG2 decode zone varies between two (2”) and
twenty (20+”) or more inches.
3. Hold the LG2 still - DO NOT SWIPE OR MOVE THE READER. Press the
trigger until the LG2 beeps, indicating the barcode has been successfully decoded.
4. The LG2 may be optimized to your specic environment by scanning barcodes in Chapter 3.

1.4 - Imager Field of View & Resolution
The LG2’s dual eld optical system may be modied based on your scanning environment. The LG2’s
megapixel imager may be set to the following two modes:
SXGA Mode: In standard SXGA mode (default), the 1.3 Million Pixel imager is divided into near eld
and far eld decode zones. In each zone the resolution is 1024 x 640 pixels (see gure 1.4). In
this mode of operation, the highest resolution, and therefore, widest working range on symbols of all
densities is achieved. The trade-off is the amount of time the reader spends processing the image.
This time can be reduced by optimization functions:

LG2 User’s Manual 25-ULG2MU01-02 - 5
Save Settings
1.4 - Imager Field of View & Resolution (con’t)
If only the near eld is used (small, high density symbols), the far eld image can be ignored. If only
the far eld is used (large, lower density symbols), the near eld can be ignored. Further optimization
may be obtained by "windowing" the eld to a smaller area. Each focal area may be narrowed by
enabling the windowing feature found in section 9.3.
VGA Mode: In VGA mode (optional selection), the 1.3 Million Pixels are sampled on a 4-to-1 basis.
This greatly reduces the amount of time necessary for the transfer of the image to the CPU and the
resulting processing time (gure 1.5). The trade-off for this increased speed is a reduction in resolution
and working range.

Overview
This version of the LG2 features a Bluetooth® wireless radio. The radio allows for point to point wireless
communication with other Bluetooth devices that support serial port protocol (SPP). The following guide
will give you general instructions on connecting your LG2 to a desktop or laptop computer with a
Bluetooth radio.
Connecting With A Quick Connect Code
The easiest way to connect to a Bluetooth device is to visit Opticon’s web site and create a Quick Con-
nect Code that is specic to your device (gure 2.9). This barcode will link your LG2 directly to the de-
sired Bluetooth device. To create a Quick Connect Code, you will need to know the Bluetooth address
(often referred to as the BD_ADDR) of that device. You can usually nd the 12-character Bluetooth
address somewhere on the device near the device’s serial number (see gure 2.10).
If you purchased a CodeXML Bluetooth Modem or a Belkin® Bluetooth adapter from Opticon or from an
authorized distributor, a Quick Connect Code is included. The CodeXML Bluetooth modem is a simple
hardware solution for customers who wish to enjoy the benets of cordless data collection without modify-
ing existing applications or installing software. Please visit www.opticonusa.com for more information. If
you bought a Bluetooth adapter separately and wish to create a Quick Connect Code, please visit Opti-
con web site at:
http://www.opticonusa.com
Note: While installing the Bluetooth Conguration Manager software that came with the adapter, make
sure to take note of the Virtual COM Port the software has assigned for the adapter (e.g. COM 10). This
is the COM Port your LG2 will connect through. Please refer to quick start guide 25-QGENB1001-02
for the latest USB Bluetooth Adapter setup instructions.
Scan the RF One Way - Max Range barcode (see discussion on next page) below then the Quick Con-
nect Code and your LG2 will automatically connect. You should also scan the Save Settings barcode
if you want to save these settings (Note: If the LG2 unit powers off without scanning the Save Settings
barcode, you will lose your settings).

Radio Range and Transferring Data
The LG2 radio is a Class 1 device. If connected to another Class 1 device the unit has roughly
a 300 foot line of sight operating range. If connecting to a Class 2 or Class 3 device, the operating
range may drop to match the lower range. Once a unit is connected, the application software on
the host must be open to receive data.
When the LG2 detects the radio is out of range, the LG2 will store data on the reader’s non-volatile memory.
The reader will continue to try and send data until radio is back in range. Once the data is sent the data will
be erased from the units memory. If the radio cannot connect in 90 seconds, it will give an error beep. The
reader will continue to try and connect until it has reached the programmable radio time out setting.
The LG2 Bluetooth protocol allows for two (2) forms of communication:
1. One Way Mode - Dened as one way communication between the reader and host. One Way
mode only recommended when connecting to a device well within itse specied range or if
connected to a device without an operating system (i.e. printer). There are two settings in this mode:
• Max Range (Default) - Greater range but data reliability is lower
• Max Reliability - Limits range but reliability is improved
RF One Way Mode (Max Range) RF One Way Mode (Max Reliability)
Note: While robust, One Way Mode doesn’t guarantee data integrity and you may have data loss.
2. RF Two Way Mode - This is two way communication between the host and reader. This requires the
implementation of software at the application level.* The reader receives conrmation via packet
protocol verication and is 100% reliable. Data will be automatically retransmitted if necessary.
RF Two Way Mode
* Note: You will need to install application software that supports packet communication to operate
in RF Two Way Mode. Opticon offers a Windows or Pocket PC version of software called
CodeXML Router - Bluetooth Edition (BE) that provides for end-to-end Bluetooth handshakes that
eliminate out-of-range data loss. CodeXML Router - BE also offers Bluetooth to keyboard wedge
communication for applications that require keyboard port input.
If you are using the CodeXML Bluetooth modem, you must use RF Two Way Mode.
