5.8.6 Batch Mode
This Operating Mode allows storing read codes in the internal gun 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:
Key Function
▲ (left) Key Scroll up in list
ENTER (center) Key Delete highlighted code
▼ (right) Key Scroll down in list
In batch mode, the selected Transmission Mode determines the behavior of the gun
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 gun 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.
