1.1 - Introduction

The CR3 establishes a new benchmark for Portable Data
Terminals and Hand Held Computers by combining the
industry’s best imaging technology with a graphic display
and rugged keyboard to create the smallest and lightest
full-featured bar code reading terminal on the market.

Using the same ergonomic platform as the highly
successful Code Reader 2.0, the CR3 extends mobile
all-symbology bar code reading to include information
display and keyboard entry.

The CR3 instantly reads large linear as well as high density matrix symbols due to Code Corporation’s
unique Dynamic Optimization Technology (DOT), which continuously adapts the resolution, illumination,
and image field for the fastest automatic symbology identification and decoding over the widest range of
symbology types, sizes, recording surfaces and ambient lighting. With DOT, the CR3 achieves matrix
symbol decoding at speeds that are similar to linear bar code decoding, while preserving battery energy.
By monitoring each user’s reading patterns, DOT reduces training time and eliminates the need for manual
configuration optimization through parameter settings.

fe atur i ng

Code eliminates the need for costly, high-overhead operating systems by providing an open platform
JavaScript development environment within its CodeXML Applications Development Suite. With CodeXML
and JavaScript, Developers and Information Technology organizations no longer need to worry about ex­pensive porting of applications between Windows, Windows Pocket PC, Windows CE.Net, et.al.. A unique
feature of the Applications Development Suite is the ability to protect both development investment and
data security by a customer-unique key encryption, which allows the developer to control the distribution
and modification of applications to specific serial-numbered CR3 units.

The CR3 features a 1.3 MegaPixel dual-field
image collection engine, a 400MHz AMD Al­chemy au1100 CPU, and 4MB of non-volatile
memory. Portable operations are supported
by a 1950 mAH Lithium Ion Battery and a Real
Time Clock with its own battery backup sys­tem. For wireless communications, a 2.4 GHz
radio system is available and compatible with
a wide range of Bluetooth™ systems, as well
as the CodeXML Modem, with a unique data
and pairing encryption system for unsurpassed
wireless data security.

The CR3 will instantly decode all bar and 2D codes

1.5.1 - Introduction

Batch data storage and data transfer are controlled by the resident JavaScript application on your CR3
reader. Please consult the manual for the application on your CR3 for instructions on how to control data
storage and transfer.

1.5.2 - RS232 Considerations

In RS232 Cabled - No Power mode, the CR3 will behave as if it is always connected even though the
serial cable is disconnected or the power adapter is unplugged. Scanned data will be sent, regardless of
connection status. Data scanned in Cabled mode will be lost if the CR3 is not connected to the serial cable.
It will not buffer the data, unless Send & Store mode has been enabled.

In RS232 Cabled mode, the CR3 will detect if it is connected to a powered serial cable, and will send the
data. If a powered serial cable is not connected or if the power adapter is not connected to the serial cable,
the CR3 will buffer the data. When the CR3 is then connected to a powered serial cable, the data will
automatically upload.

Important Note: If you are in RS232 Cabled mode, when you place a unit in a charger the reader will
behave as it is being cabled, and download the data. THE DATA WILL BE ERASED FROM MEMORY. To
disable this feature, scan the RS232 Cabled - No Power code.

1.7 - Bluetooth Radio Operation

1.7.1 - Introduction

This CR3 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 CR3 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 the Code website and create a QuickConnect
Code that is specific to your device (Figure 1.13). This code will link your CR3 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 1.14).

Figure 1.13

Figure 1.14

If you purchased a CodeXML Bluetooth Modem or a Belkin® Bluetooth adapter from Code or from an
authorized distributor, a QuickConnect Code was included. 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.

Important Note: While installing the Bluetooth Configuration Manager software that was included with

your Bluetooth adapter, make sure to note the Virtual COM Port number the software assigned for the
adapter (e.g. COM 10). This is the COM Port your CR3 will connect through.

To connect your reader, scan the Reset to Factory Defaults below then the QuickConnect Code and your
CR3 will automatically connect. You should also scan the Save Settings code if you want to save these
settings (Note: If the CR3 unit powers off without scanning the Save Settings code, you will lose your
settings).

Reset to RF Factory Defaults QuickConnect Save Settings

C002332_02_CR3 User Manual - 14

Radio Range and Transferring Data

The CR3 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 CR3 detects the radio is out of range, the CR3 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 CR3 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

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.

* Note: You will need to install application software that supports packet communication to operate

in RF Two Way Mode. Code offers the CodeXML Bluetooth Modem and 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.
