Code Alarm CR3 manual RF One Way Mode Max Range, RF Two Way Mode

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 unit’s 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 - Communication between the reader and host, that does not requrie host ackno- legement. One Way mode is only recommended when connecting to a device well within its specifi ed range or if connecting to a device without an operating system (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.RF Two Way Mode - This mode allows for two way communication between the host and reader. This mode requires the implementation of software at the application level.* The reader receives confi rmation via packet protocol verifi cation 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. 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.
