Introduction
The ER-A770 inter-register communication (IRC) system consists of one master machine and
up to 15 satellite machines/remote printers (max. 9 remote printers) which are all interconnected
by the Sharp Retail Network (SRN) to provide data transmission among them. This system
allows the manager to exercise centralized control over the satellites through the master.
• One of the satellites may be used as a back-up master.

2. Open store operation (PGM2 mode) — master and satellite
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;
From the master to the satellite
• Sending a request for the satellite to receive data (T-LOG polling)
• Sending a response to inquiry from the satellite
From the satellite to the master
• Sending a request for T-LOG polling
• Sending data to the T-LOG buffer
• Sending a request for updating of the GLU/PBLU file
• Inquiring for data on the GLU/PBLU and customer files
Open store procedure (PGM2 mode)
Select OPEN STORE from the PGM2 MODE menu and
press the [ENTER] key.
NOTE
• 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 machines whose terminal numbers
have not been programmed.
• If a transmission error occurs when 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.
* For the system retry function, please refer to pages 57 - 58.

7
3. Close store operation (PGM2 mode) —master and satellite
When the close store operation is performed at the master, the inline system is closed and the
registration function becomes unavailable at all the machines in the inline 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, any key operation in the REG or MGR mode is invalid.
Menu selection
Select CLOSE STORE from the PGM2 MODE menu and
press the [ENTER] key.
NOTE
• 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 registrations at the satellite.
• If a satellite is in the SIGN-ON state, the master encounters an error and displays the machine
number of the 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.

8
4. Sign-on operation (server assignment) (REG mode/MGR mode)
The sign-on operation is intended to assign a server to a machine (satellite or the master) and
enable him or her to perform entry operations at the machine.
If a server successfully signs on at a machine, his or her server name appears on the LCD of
the machine.
The server memory is under the control of the master.
The sign-on operation can be done whether the machine is in the open store or close store
state. If the sign-on operation is done at a machine that is in the close store state, registrations
cannot be made at the machine due to the close store condition.
Sign-on procedure
(This procedure is the same as for server assignment at a standalone machine.)
(using menu)
1. Press the [ENTER] key when the mode selection
menu is displayed. Enter your server code and press
the [SERV#] key.
2. The pop-up window for the secret code will open if
secret code is programmed. Enter your secret code
and press the [ENTER] key.
3. The pop-up window for the drawer number will open if
drawer number entry is compulsory. Enter your drawer
number and press the [ENTER] key.
NOTE
• The sign-on operation can be made only for one server at a time.
• If a server attempts to sign on when another server has already signed on, an entry error will
occur (when the stay-down server sign-on has been preset).
• Every server that is preset in the system can sign on at any machine.
• If a server has signed on at a machine, that server cannot sign on at any other machine in the
system until he or she signs off at the original machine.
• In case of trouble, the sign-on state can be cleared at the master. (Please consult your
authorized SHARP dealer for further details.)

5. Server sign-on report
A server sign-on report can be generated at the master. This report is used to determine at
which terminal each server has signed on.
Report generation procedure
1. Select “PGM2 MODE” from the mode selection menu
and press the [ENTER] key.
2. Select “INLINE READING” from the PGM2 MODE
menu and press the [ENTER] key.
3. Select “SIGN ON SERVER” from the INLINE
READING menu and press the [ENTER] key.
4. Select “DISPLAY” or “REPORT PRINTER” and press
the [ENTER] key.
Server name, server code, machine no. of
the machine at which the server has signed on

10
6. Sign-off operation
(cancellation of server assignment) (REG mode/MGR mode)
The sign-off operation is intended to cancel the assignment of a server to a machine.
The sign-off operation at a machine (master or satellite) can be done only for the servers who
have signed on at the machine and are not in the middle of a registration entry.
Sign-off procedure
Keyboard entry sequence (REG/MGR/X1/Z1/X2/Z2/PGM1/PGM2 modes)
[SERV#]
NOTE
• The sign-off operation only applies to the server who has signed on.
• If a server signs on at a machine while another server has already signed on, the latter is
automatically signed off so long as items have not yet been entered and the automatic server
sign-off system has been enabled.
For more information, please consult your authorized SHARP dealer.

7. Look-up and updating of the GLU/PBLU file
In the IRC system, the following two types of GLU/PBLU file allocation system are available: a
centralized system and an individual system.
(1) Centralized GLU/PBLU file system
In this system, the GLU/PBLU file exists only in the master. All satellites in the IRC system can
access the GLU/PBLU file in the master for registration.
GLU/PBLU-file-related inline communications are made for the following purposes:
• New order or reorder
• Payment entry or temporary finalization
• Bill printing
• Bill transfer/bill totalizing
• Bill separate
There are two types of GLU/PBLU data transmission.
1) The GLU/PBLU data is transmitted from the master to a satellite for GLU/PBLU file look-up
(in case of a new order/reorder). In this case, the GLU/PBLU reserve counter* is retained at
the master.
* The reserve counter reserves some records of GLU/PBLU files to prevent a “LACKING MEMORY” error in
finalization.
2) The GLU/PBLU data is transmitted from a satellite to the master for finalization of a
transaction (in case of payment entry or temporary finalization).
The data transmitted from the satellite is once saved in the GLU/PBLU data receiving file
and then in the GLU/PBLU file. In this case, the GLU/PBLU reserve counter is cleared at the
master.
If a satellite looks up the GLU/PBLU 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/PBLU file system
In this system, the master and satellites have their own GLU/PBLU files and look up them for
registration. Therefore, no inline communications are made regarding GLU/PBLU data.

12
8. Drive-through function
Depending on the setup of your system, drive-through data is either centrally controlled by the
master or Individually looked up at each terminal. 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 and controlled by the master
depending upon your system setup.
Automatic look-up
As drive-through codes are temporarily finalized by pressing the [SRVC] or [FINAL] key, data for
these codes is automatically looked up in the same sequence as the code was generated.
Drive-through-related inline communications are made for the following purposes:
• New order or re-order
• Payment entry or temporary finalization
• Bill 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 then 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.

13
NOTE
The drive-through system provides three types of the terminal operations (Order Taker
Machine/Cashier Station Machine/Counter Machine).
For more details about the system configuration, please consult your authorized
SHARP dealer.

9. 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.
T-LOG polling becomes available upon open-store operation and becomes unavailable upon
close store operation.
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 in the open store state.
As the master detects such a request, it starts collecting the T-LOG buffer data. After collection
of the 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.
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.
If its T-LOG buffer becomes full, registration will be disallowed at a satellite when it has been
programmed for “LOCK UP,” and allowed when it has been programmed for “CONTINUE.” For
how to specify whether the registration is disabled or enabled when the T-LOG buffer becomes
full, please refer to the ER-A770 instruction manual.

10. 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 preset data on the remote printer.
The remote printer is used to print all or part of the data entered at a machine. It is also called a
kitchen printer. It can also be operated at a location other than the kitchen.
If a remote printer number is assigned to a department or PLU, the information on the
department or PLU is output to the remote printer when an entry for the department or PLU is
made and the transaction is finalized at a machine.
The data which can be output to a remote printer is as follows:
1) Item text
2) Quantity*
3) Unit price*/Price*
4) Amount*
5) PLU/department code*
* Whether to print or not is selectable
(1) Second (back-up) remote printer
A second kitchen 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 (the receipt printed at this printer is called a chit).
For how to specify the chit print format, see page 41.
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 the backup printer.
If the backup printer encounters an error, one chit receipt is printed.

16
(2) Remote printer send function
This function allows partial food orders to be sent to the remote printers.
Which printer to receive the order is selectable.
The function is intended to allow the cooking staff to begin preparing certain items before
the entire order is given.
NK
**Case 2)
NK: 1-9
(Item entry)
*Case 1)
SEND ORDER
*Case 1)
A partial food order is sent to one or several remote printers which has been specified by
the department/PLU programming.
**Case 2)
A partial food order is sent to the remote printer specified by the system presets.
(3) Priority printing function
It is desirable for the cooking staff to see the order items that require the longest cooking
time at the top of the kitchen chit. This function can send food items in the programmed
order of priority by assigning PLUs to priority groups (1 - 9).
If an error occurs in data output to a remote printer, a corresponding error message
appears on the display and the data output to the remote printer is printed on the chit
receipt.
For remote printer error messages, see page 5.

11. Rerouting receipt/journal print data
In restaurant environments, terminals may or may not need a receipt/journal printer.
One external printer connected by RS-232 cable can be shared by two or more ER-A770
machines.
