Introduction  
The UP-820F/UP-820N inter-register communication (IRC) system consists of one master machine and up  
to 31 satellite machines which are all interconnected by the local area network (LAN) to provide data  
transmission among them. This system allows the manager to exercise centralized control over the satellites  
through the master.

2. Open store operation (OPXZ mode) – master and satellite  
When the open store operation is performed at the master, the IRC system is opened. POS can send AT  
command by this job. This function controls a modem, but doesn't have control over registration and T-LOG.  
The procedure for the open store operation is as follows.  
Select “OPEN STORE” from the OPXZ mode window and press  
the  
key.  
e
• You can also perform the open store operation at each satellite.  
• The open store operation cannot be performed at any machines whose terminal numbers have  
not been programmed.  
NOTE  
• When a transmission error occurs while the open store operation is being performed, the open  
store operation is regarded as normally terminated if the system retry function* has been  
disabled by programming. When the master has been programmed to enable the system retry  
function, it displays the machine number of the satellite that has encountered the error.  
Selecting the displayed machine number will display a prompt to retry the open store operation.  
* For the system retry function, see page 63–64.

3. Close store operation (OPXZ mode) – master and satellite  
When the close store operation is performed at the master, the IRC system is closed. POS can send AT  
command by this job. This function controls a modem, but doesn’t have control over registration and T-LOG.  
The procedure for the close store operation is as follows.  
Select “CLOSE STORE” from the OPXZ mode window and press  
the  
key.  
e
• You can also perform the close store operation at each 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.  
NOTE  
• When a transmission error occurs during the close store operation, the operation is regarded  
as normally terminated if the system retry function* has been disabled by programming. When  
the master has been programmed to enable the system retry function, it displays the machine  
number of the satellite that has encountered the error. Selecting the displayed machine  
number will display a prompt to retry the close store operation.  
* For the system retry function, see page 63–64.

4. Clerk system  
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 clerk system, consult your authorized SHARP dealer.  
(1) Centralized clerk file system  
Centralized clerk file system – without the overlapped clerk function  
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 have signed on. (For further details  
on clerk sign-on reports, see page 11.)  
Centralized clerk file system  
– with the overlapped clerk function and without overlapped clerk save files  
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.  
Centralized clerk file system  
– with the overlapped clerk function and overlapped clerk save files  
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 data. In the figure on the next page, the GLU data flows  
are omitted.)  
8
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).  
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.  
Master  
Overlapped

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.

2)  
• 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.  
NOTE  
(2) Individual clerk file system  
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.

5. Sign-on operation (clerk assignment) (REG mode/MGR mode)  
The sign-on operation is intended to assign a clerk to a machine (satellite/master) and enable him or her to  
make registrations at the machine.  
If a clerk successfully signs on at a machine, his or her clerk code appears on the LCD of the machine.  
Sign-on procedure  
(This procedure is the same as for clerk assignment at a standalone machine.)

• The PLU/EAN file (INITIAL D/L and MAINTENANCE D/L) includes LINK PLU preset data.  
• Initial downloading of all preset data (ALL PGM) should not be performed when totals exist in  
the system. (The totalizers of the receiving satellite are cleared.)  
• Performing individual initial D/L jobs will result in a non-reset error when sales data exists in the  
satellite.

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.  
17  
10. PLU/EAN stock control  
In the IRC system, the following two systems for PLU/EAN stock control are available: a centralized system  
and an individual system.  
In choosing the type of PLU/EAN stock control system, please consult your authorized SHARP dealer.  
Centralized system  
Preset stock data is stored only in the master. Stock data in each satellite must be zero before a PLU/EAN  
entry is made.  
When a consolidated report is generated, stock data in respective satellites is consolidated into the stock file  
in the master and calculated there.  
The stock data calculated at the master is displayed or printed out and the stock data in each satellite is  
reset to zero at the same time.  
Individual system  
The master and satellites store their own preset stock data. When a consolidated report is generated, the  
stock data in the master and satellites is consolidated and displayed or printed out.  
In the individual system, the consolidation does not affect the stock data in the master.  
NOTE  
18  
11. T-LOG polling  
All REG-mode transaction data in each satellite is saved in its T-LOG buffer. T-LOG polling is a data  
collecting system in which the master collects data from the T-LOG buffers in satellites.  
A request for T-LOG polling is issued from the satellite to the master when the number of data records in its  
T-LOG buffer exceeds a predetermined number.  
As the master detects such a request, it starts collecting T-LOG buffer data. After collecting data from one  
satellite, the master waits for a preset time and starts collecting data from another satellite. In T-LOG polling,  
the data transmitted to the master is stored in the corresponding file.  
The data flow in T-LOG polling is shown below.  
Master  
(4)  
(1) (2) (3)  
(5)  
Satellite A  
Satellite B  
Satellite C  
Satellite D  
Polling sequence (see the figure above.)  
(1) Satellite A makes a request for polling.  
(2) The master detects the request and starts collecting T-LOG data from satellite A.  
(3) The T-LOG data is sent to the master.  
(4) After receiving T-LOG data from satellite A, the master waits for a preset time.  
(5) The master detects a request from another satellite (B, C or D) and starts polling for it.  
You can specify in the PGM2 mode whether the entry function of a satellite is disabled (LOCK) or enabled  
(CONTINUE) when the T-LOG buffer is full.  
If it is disabled, an error message “T-LOG FULL” will be displayed and you are not allowed to make any  
entry in the REG/MGR mode at the satellite.  
If it is enabled, you can continue entries but cannot save the entered data. Even if data is entered after the  
T-LOG buffer becomes full, the previous data saved in the file will not be erased.  
• If the T-LOG buffer becomes nearly full, an alarm message pattern appears on the display of  
the satellite.  
NOTE  
• For the programming whether or not to lock a registration entry when the T-LOG file is full, see  
the “Function selection 2” of “Optional Feature Selection” section of the UP-820F/UP-820N  
Instruction Manual.  
• For the T-LOG polling between the master and MWS, please consult your authorized SHARP  
dealer.  
19  
12. PLU/EAN data control  
In the IRC system, the following two systems for PLU/EAN data control are available: a centralized system  
and an individual system.  
In choosing the type of PLU/EAN data control system, please consult your authorized SHARP dealer.  
Centralized system  
PLU/EAN sales data is centrally controlled by the master. PLU/EAN sales data which is temporarily stored  
in the T-LOG buffer of a satellite is sent to the master by T-LOG polling.  
Individual system  
The master and satellites control their own PLU/EAN sales data. PLU/EAN sales reports can be individually  
generated at each machine. Consolidation of PLU/EAN sales data can be achieved by generating the  
consolidated PLU/EAN report at the master.  
The learning function enables the operator at a satellite to set the unit price, associated  
NOTE  
department and deletion/non-deletion choice for an item whose code is undefined in the  
PLU/EAN file, and to register the transaction in the training mode. (For further information on the  
learning function, see the UP-820F/UP-820N Instruction Manual.)  
If the satellite has no dynamic EAN file, the data on the EAN item which has been set using the  
learning function is stored in the PLU/EAN main file to update the file.  
If the satellite has a dynamic EAN file, the data is stored in the dynamic EAN file to update the file.  
The data which has been set using the learning function in the training mode at a satellite is also  
stored in its T-LOG buffer.  
For the data flow, see the following figures.

13. Price change function  
When the price for an PLU/EAN item is changed at a machine (master or satellite), its PLU/EAN main file or  
dynamic PLU/EAN file is updated by the new price data (unit price and associated department). Immediately  
after this, the new data is automatically distributed to all other machines to update the PLU/EAN main files  
or dynamic PLU/EAN files which contain the code of the item.  
The data on an EAN item whose price has been changed at a satellite is also stored in the T-LOG buffer of  
the satellite. The data stored in the T-LOG buffer is collected by T-LOG polling at the master to update its  
PLU/EAN main file or dynamic EAN file.  
For further information on the price change function, see the UP-820F/UP-820N instruction manual.  
For the data flow, see the following figures.

If a transmission error occurs during automatic distribution of updated data to other machines after a  
price is changed using the price change function at a machine, the machine number of the terminal  
which causes the error and the type of error are printed out at the sending machine. In this case, the  
system retry function can be used if it is enabled. (For the system retry function, see page 63–64.)  
NOTE  
14. Customer data control  
In the IRC system, customer data is centrally controlled by the master. Customer data which is temporarily  
stored in the T-LOG buffer of a satellite is sent to the master by T-LOG polling and controlled by the master.  
(For further information on T-LOG polling, see page 19.)  
22  
15. Communication with a remote printer (option)  
When a remote printer is included in the inline system, order data is output to the remote printer according  
to the remote printer assignment.  
The remote printer, also called a kitchen printer, is used to print all or part of the data entered at a machine.  
Although kitchen may be one of the typical settings for the convenient use of the remote printer, it can also  
be used at any location.  
If a remote printer is assigned to a department or PLU, the information on the department or PLU is output  
to the remote printer when the  
The data which can be output to a remote printer is as follows:  
or  
key is pressed or the transaction is finalized at a terminal.  
ı f  
1) Item text  
2) Quantity*  
3) Unit prince*/Price*  
4) Amount*  
5) PLU/department code*  
6) Free text*  
7) Number of guests*  
* Whether to print or not is selectable.  
Second (back-up) remote printer  
A second remote printer can be assigned to each remote printer for automatic back-up.  
If an error occurs during data output to a remote printer, the data is output to the second remote printer  
assigned to it.  
If an error occurs during data output to the second remote printer, the data is output to the receipt printer of  
the terminal.  
Up to two remote printers can be preset to print data on each item (PLU or department).  
If two printers are preset to print data on each item, the data is simultaneously output to both printers.  
If either of these printers encounters an error, the data is output to its backup printer.  
If the backup printer encounters an error, a receipt is printed.  
• For the programming of remote printers, see pages 47–50.  
• Crate entry is not output to a remote printer.  
NOTE  
23  
16. Rerouting print data  
In restaurants or the like, every terminal does not need an external printer (a bill printer, a validation printer  
or a kitchin printer).  
One external printer connected by an RS-232 cable can be shared by two or more UP-820F/UP-820N machines.

4. Resetting reports in a system with no save file  
In a system which has no save file and has been programmed so as to automatically lock the satellites after  
resetting when general resetting, hourly resetting, cashier resetting or daily net resetting report is taken, the  
data in the satellites concerned is not cleared. In this case, the satellites will be locked after resetting, and  
any entry will not be allowed in the REG/MGR mode there.  
Generation of the same resetting report in the locked state will print a copy symbol on the report.  
The satellites can be unlocked by generating a consolidated resetting report at the master, or by manual  
clearing of the sales memories of the satellites.  
Your dealer can program whether or not to have save files, and whether or not to lock the satellites. For  
details, consult your local authorized SHARP dealer.

As stated earlier (see page 8), there are two systems for collecting clerk sales data: a centralized system  
and an individual system.  
(1) Centralized clerk file system  
In this system, the transaction data on a clerk in each satellite will be transmitted to the master each  
time the clerk signs off. You cannot generate an individual clerk report for each satellite. At the master,  
you can generate full and individual clerk consolidated reports.  
At each satellite, you can generate individual clerk consolidated reports.  
If resetting operation for a consolidated individual clerk Z report is made at a satellite where a clerk is  
signed on, the data on transactions being handled by the clerk or cashier is also added and printed  
out.  
If a consolidated full clerk Z report is taken at the master while a clerk signs on at a satellite, that  
clerk’s sales data are excluded from the report and resetting operation for the clerk can not be made.

satellite, the data on the clerk is not printed.)  
For detailed information on report items, see the UP-820F/UP-820N Instruction Manual.  
NOTE  
33  
(2) Individual clerk file system  
In this system, you can generate full or individual clerk consolidated X or Z reports at the master only.  
At each machine, you can generate an individual X or Z report on transactions made by an individual  
clerk or clerks assigned to the machine.  
If the system has no save file, the clerk for whom an individual Z report has been generated is not  
allowed to make registrations in the REG mode. This condition, in which registrations by the clerk are  
disallowed, is canceled when his or her sales data is consolidated and reset at the master or when the  
sales data is manually cleared. (For the manual clearing operation, see pages 61–62.)  
When an X or Z report for the locked clerk is generated again, the COPY mark will be printed in the  
report as shown below. (This COPY mark will not appear when the system has a save file.)

• For selecting whether your system should have a save file or not, consult your authorized  
SHARP dealer.  
NOTE  
• For the setting of the individual resetting data clear at the time of consolidation daily total  
resetting, please consult your authorized SHARP dealer.  
34  
6. Cashier report  
The cashier file management method in the IRC system employs a non-centralized or individual system. A  
cashier who is assigned to a machine can carry out registrations and other operations at that machine. In  
this system, you can generate full or individual cashier consolidated X or Z reports at the master only. At  
each machine, you can generate an individual X or Z report on transactions made by an individual cashier  
or cashiers assigned to the machine.  
If the system has no save file, the cashier for whom an individual Z report has been generated is not allowed  
to make registrations in the REG mode. This condition, in which registrations by the cashier are disallowed,  
is canceled when his or her sales data is consolidated and reset at the master or when the sales data is  
manually cleared. (For the manual clearing operation, see pages 61–62.)  
When an X or Z report for the locked cashier is generated again, the COPY mark will be printed in the  
report. (This COPY mark will not appear when the system has a save file.)  
When the system has a save file, the data in the save file and that in the sales file are summed up for  
consolidation.  
• The above explanation applies when the cashier system is used in addition to the clerk system.  
For the selection of the clerk + cashier system or clerk only system, please consult your  
authorized SHARP dealer.  
NOTE  
• For the setting of the individual resetting data clear at the time of consolidation daily total  
resetting, please consult your authorized SHARP dealer.  
35  
7. Reports that can be generated when the Compulsory  
Cash/Check Declaration (CCD) function is enabled  
Each machine can be programmed to enable the Compulsory Cash/Check Declaration (CCD) function. This  
function compels the operator to enter the cash/check amount in the drawer just before either an individual  
clerk/cashier Z report or a general Z report is printed.  
To take a general Z report in case of compulsory CCD function, the following two conditions are applied.  
1) If the CCD DATA is not entered in the master and the master is included in appointment of machine  
number, all consolidation report at X1/Z1 mode is not executed.  
2) If the CCD DATA is not entered in the satellite, all consolidation report is not executed.  
In the case of the individual clerk file system, you need not make any CCD entry at the master before  
generating a consolidated report. The generated report will include consolidated data on CCD entries which  
have been made to generate individual reports.  
Unless CCD entries have been made at the master and all the satellites in the IRC system to generate  
individual reports, you can not generate a consolidated report at the master.  
You can not generate some types of reports according to the table below. (For further details on this  
function, see the UP-820F/UP-820N Instruction Manual.)

System Back-Up  
1. How the IRC back-up system works  
The IRC system incorporates a back-up system.  
One of the satellites can be designated to serve as a back-up master.  
For the setup of a back-up master in your IRC system, please consult your authorized SHARP dealer.  
When both the master and back-up master are in order, the system works in the following sequence:  
Master  
Back-up master  
1) Updated data  
3) Updated data  
2) Acknowledgment signal  
4) Acknowledgment signal  
Satellite  
1) Each satellite sends updated GLU data (and clerk data*) to the master.  
2) The master receives the data and sends back an acknowledgment signal to the satellite.  
3) The satellite sends the updated data to the back-up master.  
4) The back-up master receives the data and sends back an acknowledgment signal to the satellite.  
*Only for the centralized clerk file system  
If the master breaks down, the back-up master serves as the master after a master declaration is made at  
the back-up master. If the back-up master breaks down, updated data transmission to it can be stopped by  
a master declaration at the master. When the master or back-up master recovers from the breakdown, it  
resumes its function as the master or back-up master by the recovery declaring operation.  
54  
2. Master declaration  
When the master or back-up master breaks down, the master declaration procedure should be taken to  
inform satellites of the breakdown.

1) A satellite detects a breakdown of the master through the system retry function when sending  
updated GLU data (and clerk data*) to the master. At this point, the message “MASTER DOWN?”  
appears in the pop-up window of the display of the satellite.  
(For the system retry function, see page 63–64.)  
2) The master declaration operation must be done at the back-up master. This operation informs all  
the satellites that the master has broken down and the back-up master will serve as the master  
hereafter. (During this process, any other operation cannot be done at each satellite.)  
3) Each satellite in the IRC system starts sending updated GLU data (and clerk data*) only to the  
back-up master.  
4) The back-up master receives the data and sends back an acknowledgment signal to the satellites.  
*Only for the centralized clerk file system

2) The master declaration operation must be done at the master. This operation informs all the  
satellites of the breakdown of the back-up master.  
3) Each satellite in the IRC system starts sending updated GLU data (and clerk data*) only to the  
master.  
4) The master receives the data and sends back an acknowledgment signal to the satellites.  
*Only for the centralized clerk file system  
The master declaration procedure is the same as “(1) When the master breaks down.”

2. System retry function  
If a transmission job from the master to a satellite is not performed successfully, the master either  
terminates the job immediately or awaits a command given through the keyboard, depending on whether the  
system retry function is disabled or enabled. When the system retry function is enabled, the master awaits  
entry of a command and retries access depending on the commands as explained on the following page.  
System retry function is also available at satellites depending on a transmission error.  
This function is used in the following cases:  
• The master has failed to download preset or updated data to all or some of the satellites.  
• The master has failed to collect sales report data from all or some of the satellites.  
• The satellite has failed to download data to other machines.  
• A clerk has failed to sign off at a satellite.*  
Whether the system retry function is enabled or disabled when a transmission error occurs is  
programmed both at the master and a satellite. (See “5. Specifying whether to enable or disable the  
system retry function when a transmission error occurs” on page 43.)  
*When a clerk has failed to sign off at a satellite for some reason (e.g. the master is busy), the RETRY  
and ABORT commands are available but the IGNORE command is not.  
(1) When the system retry function is disabled  
The master terminates the transmission job immediately in the following two ways.  
If none of the satellites have successfully transmitted data, the transmission is regarded as having  
ended with an error, which is equivalent to ABORT as discussed on the following page.  
If there is any satellite which has successfully transmitted data, the transmission is regarded as either  
successful or unsuccessful depending on the type of transmission job. In this case, the transmission  
regarded as successful and the one regarded as unsuccessful are equivalent to IGNORE and ABORT,  
respectively, both of which are explained on the following page.  
63  
(2) When the system retry function is enabled  
If a transmission error relating to a satellite occurs, the relevant window will appear on the display of  
the master and the master awaits entry of one of the following commands given through the keyboard:  
A) RETRY command (selection from the menu or press of the 1 key)  
B) ABORT command (selection from the menu or press of the 2 key)  
C) IGNORE command (selection from the menu or press of the corresponding key; 2 or 3 key)  
A) RETRY command:  
When RETRY is selected, the master retries to access the satellite; however, depending on the  
type of error (command error, etc.), it is obvious that the master would fail to access it again. If this  
type of error occurs during transmission, the master may not retry.  
B) ABORT command:  
When ABORT is selected, the master terminates access to the satellite and regards the  
transmission as having unsuccessfully ended. However, in the case of program data downloading,  
the ABORT command may be issued only when all the satellites accessed are in the error state.  
C) IGNORE command:  
When IGNORE is selected, the master terminates access to the satellite, regards the transmission  
as having successfully ended and prints only transmitted data.  
If no satellites have successfully transmitted data, the IGNORE command may be issued to the  
master in the case of sales data inquiry (X report), though the result is not printed.  
[Retry during sales data inquiry]  
During resetting, the ABORT command may be given only when every accessed satellite is in the  
error state. The IGNORE and RETRY commands are available unconditionally.
