Single Store
When single store mode is enabled, if the PowerScan
®
M8300 fails to transmit a
code to the cradle, it enters a special operating mode that prevents the user from
reading barcodes. When such operating mode is entered, the trigger no longer
enables barcode reading but is used to retry transmission itself for the number of
attempts selected in configuration. Once the transmission is successful the reader
returns to the standard mode. If transmission is not successful after the number of
configured attempts, the code is discarded.
Single store may be useful if you often read codes at the limit of the coverage area
and there is a chance that code transmission can fail. In such case single store
allows you to move to a more favorable position or location (i.e. closer to the cradle)
and retry transmission without the necessity of re-reading the code since it is already
stored in the reader.
Conversely, if single store is disabled, and the user wants to retry transmission, the
code must be read again, and therefore the attempt must be made from basically the
same location. If the user gives up, he does not know if the transaction was
successful. (Actually the transmission could have been successful but the cradle may
have been unable to acknowledge the message). There are applications in which
there is no risk of transmission failure. In such cases it may be better to disable
single store so that the user perceives a more consistent behavior of the trigger in
that it always corresponds to code reading.

Batch Mode
This Operating Mode allows storing read codes in the internal reader RAM memory.
The stored codes are transmitted to the base station at a later time according to the
type of batch mode selected.
Batch mode can be enabled either manually (normal batch mode) or automatically.
Normal batch mode temporarily suspends radio communication between reader and
base station allowing codes to be stored in the reader on a FIFO basis. This can be
useful for example, if codes must be read from a location where there is no radio
network. Upon returning to the system working area, this mode requires reading the
Start Normal Batch Transmission
barcode to successively transmit the list of
stored codes to the base station. The FIFO management assures that the first code
read will be the first code to be transmitted to the base station.
The
Delete Batch Data
barcode allows canceling all barcode data stored in the
reader.
Automatic batch mode allows codes to be stored in the reader on a FIFO basis
whenever the reader is out of radio range. In this case radio communication is not
suspended and transmission is attempted after each code read. If transmission
