Transaction Data Capture - TEC MA-1650-4 Series Programming Manual

10. TRANSACTION DATA CAPTURE

The Transaction Data Capture function is possible when the features of "PC Connected" and "With Transaction Data
Capture Function" are both selected in System Options. This function enables to store details of sale entries made
on each terminal into the Master Terminal as transaction data, and to transfer the data by request of the PC.
TRANSACTION DATA CONTROL
1) Transaction Data Buffering
Each terminal sends to the Master Terminal the transaction data (data of a sale finalized) when each
transaction is finalized. On V2.0 or after, each terminal also sends the transaction data to the Master
Terminal when the transaction buffer becomes full during registrations.
The Master Terminal, on receiving transaction data, stores the transaction data in the Transaction Data
Buffer.
The Transaction Data is to be controlled usually by two buffers. One is for buffering transaction data,
and the other is used for PC's data collection. When the first buffer becomes full or requested by PC,
it is released to the PC and buffering is switched to the other one.
The capacity of the Transaction Data Buffer is specified in RAM ALLOCATION SETTING (Submode
79). The specified capacity is the total value of the two buffers described above. By performing a TABLE
CLEAR (Submode 91), the Transaction Buffer of the Master Terminal will be forcibly cleared.
2) Transaction Data Collection
By request of the PC, the transaction data stored in the Master Terminal is sent to the PC. For a
Transaction Data Request command from the PC, the Master Terminal will send the transaction data
in the buffer that has been full. If neither buffers are full, the transaction data in the buffer that is now
functioning for transaction data buffering will be sent to the PC. Thus for one Transaction Data Request
command, the data stored in one buffer will be collected.
3) Process for Transaction Buffer Full
The Master Terminal checks the vacant capacity of the Transaction Data Buffer on receiving transaction
data from each terminal. When the received transaction data cannot be stored in the buffer, the Master
Terminal sends the response to indicate the buffer-full condition to the terminal. (In this system, no
warning will be made on the remaining capacity of the Transaction Data Buffer.) On receiving this
response, the terminal prints on its journal that the transaction data has not been sent.
4) Process for Transaction Data Sending Failure
When the transaction data cannot be sent to the Master Terminal due to some error, the message "IRC
CONNECT ERR" (standard program; programmable) is displayed on the terminal and operation is
stopped.
