9. Look-up and updating of the GLU file

In the IRC system, the following two types of GLU file allocation system are available: a centralized system and an individual system.

In choosing the type of GLU file system, please consult your authorized SHARP dealer.

(1) Centralized GLU file system

In this system, the GLU file exists only in the master. All satellites in the IRC system can access the GLU file in the master for registration.

The GLU file is accessed by satellites for the following purposes:

•New order or reorder

•Payment entry or temporary finalization

•Bill printing

•Slip printing

•Bill transfer/bill totalizing

•Bill separating

•Customer ordering

There are two types of GLU data transmission.

1)The GLU data is transmitted from the master to a satellite for GLU file look up (in case of a new order/reorder). In this case, the GLU reserve counter* is retained at the master.

*The reserve counter reserves some records of GLU files to prevent a “LACKING MEMORY” error in finalization.

2)The GLU data is transmitted from a satellite to the master upon finalization of a transaction (in case of payment entry or temporary finalization).

The data transmitted from the satellite is once saved in the temporary GLU data receiving file and then updated in the GLU file of the master. In this case, the GLU reserve counter is cleared at the master.

If a satellite looks up the GLU file in the master or asks the master to update the file, the backup master performs the same process as the master.

(2) Individual GLU file system

In this system, the master and satellites have their own GLU files and look up them for registration. Therefore, no inline communications are made regarding GLU data.
