1.1 - Introduction
CR2 is a revolutionary bar code and 2-dimensional code reader. Developed to be the rst 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 read 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 batch, cabled or wireless formats; handlheld,
ruggedized cabled or battery handle use-case scenarios; and lanyard hook
attachment or reader stand form factors. 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 11,000 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
specically developed so users may easily choose the device that best meets
their needs. The CR2 is available in three basic congurations:
1. CR2 Cabled - USB, RS-232 or PS/2 interfaces
2. CR2 Batch - Store and forward device with memory and long-
life battery

1.5 - Batch Operation
1.5.1 - Introduction
The CR2 unit features a batch mode for applications requiring a portable reader. Batch mode allows a user to store
scanned data to the reader’s non-volatile memory. The user may transfer the data to a host computer when needed. To
utilize batch functionality you will need to purchase the 1950 mAH Lithium Ion battery from a Code representative.
The CR2 may be programmed to operate in three different batch modes:
1. Send & Buffer Mode (Default) - In Send and Buffer Mode, the CR2 unit will automatically detect when
the USB or RS-232 cable is detached, or the Bluetooth® radio is out of range, and will switch into batch
mode and buffer the data in non-volatile memory. When the reader is reconnected to your host computer,
or when the Bluetooth Radio is back in range, the reader will auto transfer the buffered data. Once
transferred, the data is automatically erased from the reader’s memory.
Note: Once a unit is reattached to a cable or enters within radio range, any data scanned WILL NOT
be saved to the non-volatile memory. For RS-232, a power supply connection is used to detect when a
reader is attached to a host computer.
2. Log Only Mode - In Log Only Mode, the reader will only store data into non-volatile memory. You can
only retrieve the data by scanning the Transfer All Stored Data in Memory code (see explanation next
page). Once the reader’s memory has been transferred to a host computer, all of the data will still reside
in memory. A user must scan the Delete Scanned Data from Memory code to clear memory.
3. Send & Log Mode - In Send and Log Mode the reader will save a copy in non-volatile memory as well as
send the data if the reader is connected. The data can be retrieved by scanning the Transfer All Stored
Data in Memory code or the Transfer Only Unsent Data in Memory code (see explanations next page).
Once the reader’s memory has been transferred to a host computer, all of the data will still reside in
memory. A user must scan the Delete Scanned Data from Memory code to clear memory.
Note: The reader can be dened as connected if:
1) The Bluetooth radio is in range;
2) The USB cable is attached to a host and the reader is enumerated;
3) The reader is in RS-232 Cabled - No Power mode; or
4) The RS-232 cable is attached to host with power supply and the reader is in
RS-232 Batch-Cable Detect (Default) mode.
The CR2’s dedicated batch memory is a minimum of 1MB. To determine the number of reads that may be stored, divide
the average bytes of a scan into the total minimum memory.
Feedback
After a successful decode in batch mode, the unit will beep once and the memory LED will ash either red or amber
depending on memory level, and every 15 seconds the battery LED will ash green, amber or red depending on the
battery level. This feedback behavior is accurate when a reader is cabled or uncabled.
Save Settings
C001537_18_CR2_User_Manual 6
Transferring and Deleting Data
There are three different codes to transfer and delete data in memory.
1. Transfer All Data in Memory - This code will send all data in memory everytime the code is scanned.
2. Transfer Only Unsent Data in Memory - This code will send only the data in memory that hasn’t already been sent
when the code is scanned (ONLY works in Send & Buffer and Send & Log modes).
3. Delete Scanned Data from Memory - Scanning this code will erase all data in the reader’s non-volatile memory.
Auto Transfer Buffer Memory
By default, when reconnected, the CR2 will automatically transfer any data in memory once a connection to a host is
established. If your application is not ready, the reader will send the data anyway and the data could be lost. If you do
not wish for the reader to immediately send data upon connection, please scan the Disable Auto Transfer Buffer Memory
code.
Send & Buffer Mode (Default) Log Only Mode Send & Log Mode
Transfer Only Unsent Delete Scanned Data
Transfer All Data in Memory Data in Memory from Memory
Enable Auto Transfer Disable Auto Transfer
Buffer Memory (Default) Buffer Memory
RS-232 Considerations
In RS-233 Cabled-No Power mode, the CR2 will behave as if it is always connected even though the serial cable is
disconnected or the power adapter is unplugged. Data scanned will be sent, regardless of connection status. Data
scanned in Cabled-No Power mode will be lost if the CR2 is not connected to the serial cable - it will not buffer the data,
unless Send & Log or Log Only mode has been enabled.
In RS-232 Batch-Cable Detect (Default) mode, the CR2 will detect if it is connected to a powered serial cable, if it is , it
will then send the data. If a powered serial cable is not connected or if the power adapter is not connected to the serial
cable, the CR2 will buffer the data. When the CR2 is then connected to a powered serial cable, the data will automatically
upload.

1.7 - Bluetooth Radio Operation
1.7.1 - Introduction
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). If keyboard entry is necessary, Code XML Router will need to be
installed. 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 the Code website and create a QuickConnect Code that is
specic to your device (Figure 1.22). 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 nd the 12-character Bluetooth address somewhere on the device near the device’s serial number (see
Figure 1.23).
Figure 1.22
Figure 1.23
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’s web site at: http://www.codecorp.com/bdaddr.php.
Important Note: You will need to locate the Communications (COM) Port assigned to the Bluetooth serial port protocol.
While installing the Bluetooth Conguration Manager Software that was included with your Bluetooth adapter, make sure
to note the Communications (COM) Port number the software assigned for the adapter (e.g., COM 10). This is the COM
Port through which the CR2 will connect.
To connect your reader, use the following steps:
1. Power on the CR2 reader by pressing one of the red buttons for one second to power on the reader.
2. Scan the Reset to RF Factory Defaults Code (M684_01).
3. Scan the Quick Connect Code you receieved or created from Code’s website.
4. The CR2 will automatically connect to the computer. By default, the CR2 will beep once after it connects
and beep four times in a row if it did not connect.
5. Scan the Save Settings Code (M188_02) if you want to save the wireless connection settings to the CR2 so
that the CR2 will automatically try to connect wirelessly the next time it is powered on.

1.7 - Bluetooth Radio Operation (continued)
Radio Range and Transferring Data
The CR2 radio is a Class 1 device. If connected to another Class 1 device the reader has roughly a 100 meter (300 feet)
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 reader is connected, a serial application must be opened (HyperTerminal) unless Code XML Router
is installed.
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
reader’s memory. 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. Standard Bluetooth Reliability Mode (previously One Way Mode) - Communication between the reader and host,
that does not require host acknowledgement. This mode is only recommended when connecting to a device well
within its specied range or if connecting to a simple device (e.g., 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 Standard Bluetooth RF Standard Bluetooth
Reliability Mode (Max Range) Reliablility Mode (Max Reliability)
Note: One Way Mode doesn’t guarantee data integrity, and you may have data loss when operating in the
fringes of radio range or in the presence of radio interference.
2. Additional Bluetooth Reliability Mode (previously Two Way Mode) - This mode requires the implementation of
software at the application level.* The reader receives conrmation via packet protocol verication and is 100%
reliable. Data will be automatically
retransmitted if necessary.
RF Additional Bluetooth
Reliability Mode
* Note: You will need either Code XML Router Software or a Code XML Bluetooth Modem on the PC side to use the
Additional Bluetooth Reliability Mode.
If you are using the CodeXML Bluetooth Modem, you must use RF Additional Bluetooth Reliability Mode.
