Batch Mode
This Operating Mode allows storing read codes in the internal reader 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 (first in, first out) 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 cannot be successfully
completed, then the code is added to the list. When the reader 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.
In batch mode, the selected Transmission Mode determines the behavior of the reader at the
time the list of codes is transmitted. If One-way mode is enabled, the codes are transmitted
one after the other without interruption. In Two-way mode, after transmitting each code,
the reader waits for the Host answer message to be shown on the display. Therefore, in Two-
way transmission mode and normal batch mode, the Start Normal Batch Transmission
barcode must be read after each code to continue; whereas with automatic batch mode, just
pull and release the trigger after each code.
3-KEY MODEL
Each code is listed on the reader 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:
The code which has a transmission pending is shown on the display in reverse video,
indicating that it cannot be deleted.
Find Me
If enabled, after a timeout of a few minutes in which PowerScan
®
M8500 is not used, it
enters stand-by mode and its green LED starts blinking in order to signal its location.
