When the open store operation is performed at the master, the IRC system is opened and the

registration function becomes available at all the machines in the IRC system. The following

types of communications between the master and satellites are allowed.

• Sending a request for the satellite to receive data (T-LOG polling)

• Sending a response to inquiry from the satellite

• Sending data to the T-LOG buffer

• Sending a request for T-LOG polling

• Sending a request for updating of the GLU/PBLU file

• Inquiring for data on the GLU/PBLU

Select OPEN STORE from the PGM2 MODE window and

press the 

ENTER

 key.

•

You can also perform the open store operation at each satellite. Once the open store

operation is performed at a satellite, you can make registrations at the satellite. When you

perform the open store operation at the satellites, T-LOG polling will not take place.

•

The open store operation cannot be performed at any machine whose terminal number has

not been programmed.

•

If a transmission error occurs while the open store operation is being performed, the master

displays and prints (journal printer) the machine number of the satellite that encountered the

error. When the master has been programmed to enable the system retry function*, a prompt

to retry the open store operation will be displayed.

When the close store operation is performed at the master, the IRC system is closed and the

registration function becomes unavailable at all the machines in the IRC system. It should be

noted that for the close store operation, all the satellites must be in their SIGN-OFF state. After

this operation, the communications between the master and satellites which have been enabled

with the open store operation are disabled. The master, however, can download preset data and

reset the sales data at satellites.

In the close store state, key operations in the REG or MGR mode is invalid.

Select “CLOSE STORE” from the PGM2 MODE window

and press the 

ENTER

 key.

•

You can also perform the close store operation at each satellite. Once the close store

operation is performed at a satellite, you can no longer make a registrations at the satellite.

•

If a satellite is in the SIGN-ON state, the master locates this error and displays the machine

number of the corresponding satellite.

•

When the close store operation is performed, the data remaining in the T-LOG buffers of all

the satellites is collected by the master.

•

If a transmission error occurs during the close store operation, the master displays and prints

(journal printer) the machine number of the satellite that has encountered the error.

In this case, a prompt to attempt a retry is displayed when the system retry has been enabled.

In the IRC system, the following two types of clerk file systems are available: a centralized

system and an individual system. In the centralized clerk file system, the master manages

transaction data on clerks within the IRC system. In the individual clerk file system, each

machine manages its clerk transaction data.

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

In this system, each clerk file is under the centralized control of the master and programming for

clerks has to be done only at the master. When a clerk signs on at a satellite, a communication

between the satellite and the master will begin. You can generate a report listing clerks which

In this system, each overlapped clerk file is under the centralized control of the master and

programming for clerks has to be done only at the master. When a clerk signs on at a satellite, a

communication between the satellite and the master will begin.

When the clerk signs off, the overlapped clerk data is transferred to the master and saved in its

overlapped clerk file.

In this system, each overlapped clerk file is under the centralized control of the master and
programming for clerks has to be done only at the master. The way data flows differs depending
on whether or not the clerk signs on at the same satellite as the one used in his or her previous
operation. (The data which flows in the system includes not only clerk data but also GLU/PBLU

data. In the figure on the next page, the GLU/PBLU data flows are omitted.)

1) When the clerk signs on at a machine other than the one used in his or her previous

operation:

In this case, the overlapped clerk data is sent from the master to the satellite (transfer of

overlapped clerk data).

• For selecting whether your system should have the overlapped clerk function or not, and

whether it should have overlapped clerk save files or not, consult your authorized SHARP

dealer.

• To use the overlapped clerk function in the IRC system,  the overlapped clerk function must be

enabled for all the master and satellite machines.

In this system, each clerk file is under the control of a satellite and you have to do programming

for clerks at each satellite. Even if a programmed clerk signs on at a satellite, a communication

with the master will not begin.

The overlapped clerk file in a satellite can only be accessed by the satellite itself. The data in the

clerk files at all satellites will be collected by the master each time a consolidated report is

issued.

2) When the clerk signs on at the same satellite as the one used in his or her previous

operation:

In this case, no data transfer occurs between the master and the satellite but the data stored in

the save file of the satellite is called back. This permits quicker data look-up than above in 1).

In both cases, the overlapped clerk data is

saved in the master's overlapped clerk file as

well as the satellite's overlapped clerk data save

file upon sign-off operation.

Whether the centralized clerk file system is

used with or without an overlapped clerk save

file, the master's overlapped clerk file can be

accessed from any machine in the IRC system.
