10. Drive-through function
There are two types of drive-through file allocation system: a centralized system and an
individual system. In the centralized file system, drive-through data is centrally controlled by the
master while in the individual file system, the drive-through file in a satellite can be looked up by
the satellite itself. For more information, please contact your authorized SHARP dealer.
Automatic code generation
Drive-through codes are generated automatically: when the end code for a transaction is
generated, the start code for another transaction is automatically generated.
The start/end codes are programmable in the PGM mode.
Automatic look-up
As drive-through codes are temporarily finalized by pressing the
NBAL
or
FINAL
key, data for these
codes is automatically looked up in the same sequence as when the codes were generated.
Drive-through-related files are accessed for the following purposes:
• New order or reorder
• Payment entry or temporary finalization
• Bill printing
• Slip printing
(1) Centralized file system
In this system, the drive-through data is transmitted from the master to a satellite for drive-
through file look-up (in case of a new order/reorder). In this case, the drive-through reserve
counter is retained at the master.
Data is transmitted from a satellite to the master for finalization of a transaction (in case of a
payment entry or temporary finalization). The data transmitted from the satellite is once saved in
the temporary drive-through data receiving file and then in the drive-through file. In this case, the
drive-through reserve counter is cleared at the master.
(2) Individual file system
In this system, the master and satellites have their own drive-through data files. They access
their own drive-through files for new orders or reorders. The drive-through data of the master or
a satellite is saved in its drive-through file for finalization of a transaction (in case of a payment
entry or temporary finalization). Therefore, no inline communications are made regarding drive-
through data.
