1.9 - Bluetooth Radio Operaon (Connued)

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 operang range. If connecng to a Class 2 or Class 3 device, the operang range may drop to match the lower range. Once

a reader is connected, a serial applicaon 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-volale memory. The reader

will connue to try and send data unl radio is back in range. Once the data is sent the data will be erased from the reader’s

memory. The reader will connue to try and connect unl it has reached the programmable radio me out seng.

The CR3500 Bluetooth protocol allows for two (2) forms of communicaon:

1. Standard Bluetooth Reliability Mode (previously One Way Mode) - Communicaon between the reader and host, that

does not require host acknowledgement. This mode is only recommended when connecng to a device well within its

specied range or if connecng to a simple device (e.g., printer). There are two sengs 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 operang in the

fringes of radio range or in the presence of radio interference.

2. Addional Bluetooth Reliability Mode (previously Two Way Mode) - This mode requires the implementaon of soware

at the applicaon level.* The reader receives conrmaon via packet protocol vericaon and is 100% reliable. Data will

be automacally retransmied if necessary.

* Note: You will need either CodeXML® Router Soware or a CodeXML® Bluetooth Modem on the PC side to

use the Addional Bluetooth Reliability Mode.

If you are using the CodeXML® Bluetooth Modem, you must use RF Addional Bluetooth Reliability Mode.
