Radio Range and Transferring Data
The CR3500 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 CodeXML® Router is installed.
When the CR3500 detects the radio is out of range, the CR3500 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 CR3500 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
specified 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

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 confirmation via packet protocol verification and is 100% reliable. Data will
be automatically retransmitted if necessary.

* Note: You will need either CodeXML® Router Software or a CodeXML® 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.
