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.
5.9.6 Batch Mode
This Operating Mode allows storing read codes in the internal gun 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 gun and
base station allowing codes to be stored in the gun 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 gun.
Automatic batch mode allows codes to be stored in the gun on a FIFO basis
whenever the gun is out of radio range. In this case radio communication is not
suspended and transmission is attempted after each code read. If transmission
cannot be successfully completed, then the code is added to the list. When the gun
returns in range, transmission of the codes to the base station resumes
automatically, according to the selected communication protocol, upon simply
pressing and releasing the trigger or by successfully reading a new code.
Each code is listed on the gun display together with its identifying position number
and its total number of characters. The three keys under the display have the
following function in batch mode:
