Radio Range and Transferring Data
The LG2 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 LG2 detects the radio is out of range, the LG2 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 LG2 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. Opticon 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.
