Data Buffer Function
These functions erase and/or transmit the data that is stored in the product’s NVM.
Table 4-25 lists the data buffer commands.
Table 4-25 Data Buffer Commands
Function Name
Data Buffer Clear
<TYPE> <CMD>: \0A\0B\
Description
This function erases the product data buffer (used in buffering mode, for example).
Note: It is highly recommended to use the high-level acknowledge (ACC) of the RC
Protocol (default setup) for this function due to the long time necessary to clear the
buffer in flash memory (seconds). If simplified acknowledgement is selected, it is
necessary to wait a few seconds before sending another command.
Parameters
None
Responses
IEC (IMC not activated)
ACC (command accepted and started)
NAC (command not recognized)
Function Name
Transmit Data Buffer
<TYPE> <CMD>: \0A\0C\
Description
This function transmits data that has been previously stored in the data buffer to a host
application or terminal. An ASI response is sent to the host with a word parameter
Number_of_Frames to indicate the number of data frames that will be sent (each frame
corresponding to a successful barcode read or transaction with a tag). The product then
sends a quantity of consecutive BFR data records, equaling the Number_of_Frames
sent in the preceding ASI response.
Parameters
None
Responses
<ASI><IMC><Transfer Data Buffer = 0x0C><Number_of_Frames>
Number_of_Frames is a 2-byte field indicating the number of BFR frames to be sent to
the host.
