CR2 is a revolutionary new bar and 2-dimensional code reader. Developed to be the first universal
reader, no other single device performs as many functions. With a cost of ownership far less than
comparable systems, the CR2 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 codes and larger low density linear codes
• Superior working range
• High-speed omni-directional decoding
• Cordless and cabled interfaces
• Unsurpassed data rates
The CR2 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 CR2 is rugged and lightweight
and the cordless version will operate for more than
a complete shift at the highest use rate. The CR2
performs more than 3000 reads and transmits from a
single battery charge. The CR2 will automatically
discriminate between all major 2-D matrix and linear
bar code symbologies and features a timestamp
feature for logging data.
Whether you need a small, palm-held device or a traditional gun, CR2 was specifically developed
so users may easily choose the device that best meets their needs. The CR2 is available in three
basic configurations:
1. CR2 Cabled - USB, RS232 or PS/2 interfaces
2. CR2 Batch - Store and forward device with memory and long-life battery
3. CR2 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 Code at [phone].
The standard CR2 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 CR2.
• 3 cable options (USB, RS232 or PS/2)
• 1400 mAH or 1950 mAH long-life 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 CR2 is shipped in an approved shipping
container and should be used if you ever need to return your equipment for servicing.
The CR2 utilizes digital camera technology to take a picture of a symbol. Once an image is captured,
the CR2 utilizes advanced decoding algorithms to extract data from the captured image.
The CR2 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 (figure 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 (figure 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 CR2:
1. The CR2 features omnidirectional decoding. Center the symbol in any orientation within
the laser dot aiming pattern (figure 1.3).
Note: The CR2 can read a symbol that is not centered however, the CR2 performs best
when a code is centered. If two (2) bar codes are with the imagers decode zone, the CR2
will decode the symbol closest to the center of the aiming dot.
2. The CR2 was developed to decode both very small 2-dimensional symbols and larger
1-dimensional symbols. The unit features two imagers to create an innovative dual
decode zone. The CR2 features a high speed processor and DECODES BOTH
ZONES SIMULTANEOUSLY. The unit has one imager focused on a near-field for
smaller codes (optimal focal point is 4 inches) and one imager focused on a far-field
for larger codes (optimal focal point 9 inches). To read smaller symbols move the CR2
closer to the symbol. To read larger symbols move the unit farther away from the
symbol (see figure 1.4). The entire CR2 decode zone varies between two (2”) and
twenty (20+”) or more inches.
3. Hold the CR2 still - DO NOT SWIPE OR MOVE THE READER. Press the
trigger until the CR2 beeps, indicating the code has been successfully decoded.
4. The reader may be optimized to your specific environment by scanning codes in Chapter 3.

1.4 - Imager Field of View & Resolution
The CR2’s dual field optical system may be modified based on your scanning environment. The
CR2’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 field
and far field decode zones. In each zone the resolution is 1024 x 640 pixels (see figure 1.4). In this
mode of operation the reader utilizes the highest resolution creating the widest working range on
bar code and 2-dimensional symbols of all densities. The trade-off is the amount of time the reader
spends processing the image. This time can be reduced by optimization functions:

C001537_04_CR2 User Manual - 5
Save Settings
1.4 - Imager Field of View & Resolution (con’t)
If only the near field is used (small, high density symbols), the far field image can be ignored. If only
the far field is used (large, lower density symbols), the near field can be ignored. Further optimization
may be obtained by "windowing" the field 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 (figure 1.5). The trade-off for this increased speed is a reduction in resolution
and working range.

Figure 2.9 Figure 2.10
Overview
This version of the CR2 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 CR2 to a desktop or
laptop computer with a Bluetooth radio.
Connecting With A QuickConnect Code
The easiest way to connect to a Bluetooth device is to visit Code’s web site and create a QuickConnect
Code that is specific to your device (figure 2.9). This code will link your CR2 directly to the desired
Bluetooth device. To create a QuickConnect Code, you will need to know the Bluetooth address
(often referred to as the BD_ADDR) of that device. You can usually find the 12-character Bluetooth
address somewhere on the device near the device’s serial number (see figure 2.10).
If you purchased a CodeXML Bluetooth Modem or a Belkin® Bluetooth adapter from Code or from an
authorized distributor, a QuickConnect Code is included. The CodeXML Bluetooth modem is a simple
hardware solution for customers who wish to enjoy the benefits of cordless data collection without
modifying existing applications or installing software. Please visit www.codecorp.com for more
information. If you bought a Bluetooth adapter separately and wish to create a QuickConnect Code,
please visit Code web site at:
http://www.codecorp.com/support/bdaddr.php.
Note: While installing the Bluetooth Configuration 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 CR2 will connect through.
Scan the RF One Way - Max Range code (see discussion on next page) below then the QuickConnect
Code and your CR2 will automatically connect. You should also scan the Save Settings code if you want
to save these settings (Note: If the CR2 unit powers off without scanning the Save Settings code, you will
lose your settings).

2.4 - Bluetooth Radio Overview

C001537_04_CR2 User Manual - 12
Save Settings
Radio Range and Transferring Data
The CR2 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 CR2 detects the radio is out of range, the CR2 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 CR2 Bluetooth protocol allows for two (2) forms of communication:
1. One Way Mode - Defined as one way communication between the reader and host. One Way
mode only recommended when connecting to a device well within itse specified 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 confirmation via packet
protocol verification 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. Code 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.
