7.3 How to Read / Write TAG Memory

All RFID tags have an unique identifier (Tag ID), and some of them have also a non-volatile memory (TAG Memory) in which it is possible to read and write (with or without security).

Note: the TAG ID of a RFID tag is different from its TAG MEMORY.

Unlike reading a tag ID, the read / write memory (TAG MEMORY) operation is only possible in real time. As a consequence, the Host has to be connected the DualRunners. This is the host that sends commands to read / write in the memory.

During this read/ write operation, the RSL led will be orange (solid). When there is a lack of data exchanges between the tag and the DualRunners (ie : interrogator), it will emit a “Tic” sound. In that case, approach it to the tag in order to complete successfully the ‘read / write’ operation.

7.4 The different usage modes

Real Time mode

In real time mode, the data is decoded and transmitted to the remote host without any delay. If the scanner is not connected, the data is lost (Status RSL Led: red flash).

Real Time mode with No Data Loss option

If the No Data Loss option is activated and if the scanner is not connected or out of Bluetooth range, the scanner will store the data. It can memorise up to 20 000 barcodes (UPC format) or TagID and later automatically upload them to the remote host when a Bluetooth connection is established to the host.

Every data sent to the host must be acknowledged by the host. If the host fails to send an acknowledgement, the scanner will continue to transmit the data until the host does send an acknowledgement.

This acknowledgment is disabled in the default settings. It is strongly recommended to set the No Data Loss mode to ON. This configuration can be set with the BaracodaManager software or with the Programming Guide.

Additionally, this protocol acknowledgment allows an end user to set an audio acknowledgment indicating that the data has been successfully transmitted to the host.

Batch mode

Datas are always stored in the scanner. Once the batch mode is selected, the BCL led (right) emits an orange flash. In batch mode, the DualRunners can read up to 20 000 barcodes (UPC format) or TagID and store them into its non-volatile memory for later transmission to the host.

To upload datas from the scanner, connect it to the host computer via Bluetooth. The BaracodaManager software is used to configure the location where the datas are sent once the datas are extracted from the scanner.
