DETAILED DESCRIYrION OF THE PREFERRED EMBODIMENT
Fig. l is a diagram showing an arrangement of a transaction processing system to which a card authorization terrninal system in an embodiment of the present invention is applied. In Fig. l, this transaction processing system comprises a plurality of CATS l, a cluster controller 2, and a host computer 3. The CATS 1 are provided to authoriz cards. At least one of the CATS l functions as a parent CAT (la) serving as a transmitting side when data or the like is set. The other CATS 1 function as satellite CATS (lb) which receive the data transmitted from the parent CAT la and store it. In this embodiment, for example, all of the fifteen CATS 1 connected to a data transmission line 4 ha-~e both of the functions of the parent (:A'l' la and satellite CAT lb. Therefore, there is an advantage such that when data is set into an arbitrary CAT, by merely performing the DLL (down line loading), the same data can be set into the other CATS.
The cluster controller 2 has a function to manage $he C~TS 1 and allows the data transmission to be executed among the CATS l and the host computer 3. The group of CATS I and the cluster controller 2 can be connected by the data transmission line 4. However, in the case of performing the DLL among the CATS l, there is no need to connect the cluster controller 2 therewith. In this embodiment, an address of each apparatus is used ts~ indicate the reception side and transmitting side. The address is e~pressed by a hexadecimal numbers. For example, "00" is assigned to the cluster vntroller 2. "0l" is assigned to the parent , .
~L3~78 -~-G
CAT la. "02" to "OF" are assigned to fourteen satellite CATS Ib. The other addressçs m~y be also assigned. The host computer 3 receives the authorization data from the CAT I and discriminates whether this data can be authorized or not. Then, $he host computer 3 sends the result of the discrin~ination to the relevant CAT.
Fig. 2 is an external perspestive view of the CAT 1 shown in Fig. 1.
In Fig. 2, the main unit of the CAT 1 has a keyboard 11, a display device 12 and a card reader 13 (a manual scanning groove of the card is indicated at 13a). A PIN (personal identification number~ pad 14 is connected to the CAT 1. As will be explained hereinlater with reference to Fig. 3, the keyboard 11 includes keys to input set data and to instruct the DLL of the set data. The display device 12 displays the characters to guide the operations, the data input by the keyboard 11, and the like. The card reader 13 reads the card data from a customer's credit card. The PIM pad 14 is used for a customer to input his personal identification secret number.
Fig. 3 is a diagram showing a key arrangement on the keyboard shown in Fig. 2~ In Fig. 3, the keyboard 11 has a DLL key 111, te-n-keys 112, a set key 113, and a clear key 114. The DLL key 111 is operated when the DLL is perforrned for another CAT. The ten-keys 112 and set key 113 are operated when the CAT on the reception side is instructed. The clear key 114 is operated when the operating mode is returned to the initial state after completion of the DLL.
Fig. 4 is a schematic block diagram showing an electrical ~L3~
arrangement of the CAT 1 shown in Fig. 2. In Fig. 4, the CAT 1 has a CPU 15. The foregoing keyboard 11, display device 12, and the card reader 13 are connected to the CPU 15. Further, a PIN pad interface 16, an LAN
interface 17, an lROM 18, and an RAM 19 are also connected to the CPU
S 15. The PIN pad 14 is connected to the PIN pad interface lh. The LAN
interface 17 is connected to the cluster controller 2 through the data trallsrnission line 4. An operation program for the CPU 15 executed based on a flowchart as shown in Fig. 8, which will be e~plained hereinlater, is stored in the ROM 18. When the CAT 1 functions as the parent CAT la, the data to be transmitted to the satellite CATS lb is stored in the RAM
19. When the CAT I fimctions as the satellite CAT lb, the data ~ransmitted from the parent CAT la or the like is stored in the RAM 19.
Figs. S and 6 are diagrams showing flows of messages which are transmitted and received between the parent CAT la and the satellite CATS Ib. Particularly, Fig. 5 shows the case where the DLL is performed from one parent CAT to one satellite CAT. Fig. 6 shows the case where the DLL is executed from one parent CAT to all of the other satellite CATS.
When the DLL is performed between one parent CAT and one satellite CAT, as shown in Fig. 5, the address (in this case, N) of the satellite CAT is design~ed and a DLL activation message is transmitted.
Thereafter, the messages including the data to be set and stored into the satellite CAT ~hereinafter, this data is referred to as DLL data~ are sequentially transmitted. After com~letion of the transmission of the DLL
data, the p~ent CAT transmits a DLL end message to the satellite CAT.
In response to the reception of the DLI, end message, the satellite CAT
designates the address (in this case, M = 01) of the parent CAT and transmits the message indicative of the result of the DLL to the parent CAT.
When the DLL is executed to all of the satellite CATS among one X
~36~
parent CAT and n satellite CATS, as shown in Fig. 6, the address of the satellite CAT (in this case, the address "FF" to designate all of the satellite CATS is used) is designated and the DLL activation message is transmitted. ~ereafter, the messages including the DLL data are S sequentially transmitted ~o all of the satellite CATS. After completion of the trallsrnission of the DLL data, the parent CAT f*st transmits the DLL
end message to the satellite CAT of the address "02". When lhe DLL
result message is sent from the satellite CAT of the address "02", the parent C~T then transmits the DLL end message to the satellite CAT of the address "03". In this manner, the DLL end messages are sequentially transmitted to the satellite CATS.
Figs. 7a to 7d are diagrams showing a format of each message which is used in the operations shown in Figs. S and 6. Particularly, Fig.
7a shows a DLL activation message. Fig. 7b shows a DLL data message.
Fig. 7c shows a DLL end message. Fig. 7d shows a DLL result message.
A DLL activation message 20 sho vn in Fig. 7a comprises a reception side address, a transmitting side address, and a code "0"
, .
~3~4~
indicative of the DLL a~tivation message. If the reception side address is one of "Ol" ~o "OF", this means that the message is transrnitted to one of the satellite CATS Ib shown in Fig. l. If the reception side address is "FF", this means that the message is transmitted to all of the satellite CATS Ib.
S A DLL data message 30 shown in Fig. 7b comprises a reception side address, a transn~itting side address, a code "l" indicative of the DLL
data message, an address in the memory, a data length, and data in the memory. The address in the memory is the information to designate the storage area in the memory of the satellite CAT. The data length represents the length of data in the memory which is set. The data in the memory denotes the memo~y content which is set into the satellite CAT by the DLL.
A DLL end message 40 shown in Fig. 7c comprises a reception side address, a transmitting side address, and a code "2" indicative of the DLL
end message.
A DLL result message 50 shown in Fig. 7d comprises a reception side address, a transmitting s;de address, a code "3" indicative of the DLL
result message, and a code "O" or "l" representative of the result of the DLL. The code "O" indicative of the result of the DLL means that the DLL has normally been finished. The code "l" dènotes that an abnormality occurred in the DLL
Fig. 8 is a flowchart for explaining the operation of the CAT to which the embodiment of the invention is applied. The operation of the .
.
~3~47~3 ~, , ~, CAT to which the embodiment of the invention is applied will now be described in detail with reference to Figs. 1 to 8.
The CPU 15 first performs the initialization. Then, a guide sentence "Please press a business key" is di~splayed by the display device 12.
S Nex~, the terminal waits until a key is input or the DLL activation message 2n from another CAT is received.
When an operator performs the DLL by using the C~T which is at present being operated as the parent CAT, he or she presses the DLL keys lll of the keyboard ll. In response to the key depression, the CPU 15 displays a guide sentence "Please designate an address" by the display device 12. To designate an address, the ten-keys 112 are operated to input hexadecimal numbers of two digits, and the set key 113 is subsequently pressed. When either one of the addresses "Ol" to 'IOF'' is designated, the CPU 15 allows the display device 12 to display the information indicating that the DLL is being performed. The DlL is executed between one parent CAT and one satellite CAT as shown in Fig. 5. Subsequently, the result of the DLL is displayed on the displ~y device 12 by displaying the characters "DLL", the reception side address "XX", and the code "Y"
indic~tive of the result of the DLL in accordance with this order. If Y is set to "0", this means that the DLL has normally been finished. If Y is set to "1", this means that the abnormali~ occurred in the DI L. If Y is set to "2", this means that the DLL result message SO is not received. After ~3~ 7~
that, the CPU 15 waits until the clear key is input. When the clear key 114 is operated, the operating mode is returned to the initial state.
On the other hand, if "FF" is designated as the reception side address, the CPU 15 allows the clisplay device 12 to display the information indicating that the DLL is being executed. Ihen, the DLL is executed among one parent CAT and n satellite CATS as shown in Fig. 6. After that, the CPU 15 displays the result of the DLL by the display device 12 by displaying, for example, the characters "DLL" and the codes Y2, Y3, ..., Y~
indicative of the result of the DLL in each CAT. If Yn (n -1 to F) is set to "0", this means that the DLL has norrnally been completed. If Y" is set to "1", this means that the abnormality occurred in the DLL. If Yn is set to "2", this means that the DLL result message 50 is not received.
Subsequently, the CPU 15 waits until the clear key is input. When the clear key 114 is operated, the operating mode is returned to the initial state.
The operation of the satellite CAT will now be explained. The operation of the satellite CAT is similar to the foregoing parent CAT until the process for initialization or the state in which the CPU 15 waits fi)r the key input or the activation of the DLL; thereore, the description of this operation is omitted. When the CPU 15 of the satellite CAT received the DLL activation message 20 transmitted through the data transmission line 4, the CPU 15 discriminates whether this message is the DLL activation message to the self CAT or to all of the CATS or not on the basis of the :
\~
reception side address included in the DLL activation message 20. If it is the DLL activation message to the self CAT or to all of the CATS, the information indicating that the DLL is being executed is displayed on the display device 12. Then, the DLL data message 30 sent from the parent S CAT is received. 'rhe transrnitted data is written into the memoIy areawhich is designated by the address in the memory included in the DLL
data message 30. When the DLL end message 40 is transmitted from the parent CAT, the DLL result message 50 is transmitted to the parent CAT
through the data transmission line 4. Then, the CPU l5 allows the display device 12 to display the result by displaying, for example, "DLL OK" or "DLL NG". Next, the CPU 15 waits until the clear key is input. When the clear key 114 is pressed, the operating mode is returned to the initial state.
On tbe other hand, when the DLL activation message 20 transrnitted from the parent CAT through the data transmission line 4 is not the DLL activation message to the self CAT but the DLL activation message to another CAT, the CPU 15 further waits until a key is input or until the DLL is activated.
As described above, according to this invention, a plurality of CATS
are connected to the data transmission line and the data read out of the memory mealls of parent CAT is $ransrnitted to satellite CAT through the data transm~ssion line and written into the memory means in this satellite CA~. Thus, the data or the like can be easily set without passing through any apparatus.

Particularly, Fig. 5 shows the case where the DLL is performed from one parent CAT to one satellite CAT. Fig. 6 shows the case where the DLL is executed from one parent CAT to all of the other satellite CATS.
When the DLL is performed between one parent CAT and one satellite CAT, as shown in Fig. 5, the address (in this case, N) of the satellite CAT is design~ed and a DLL activation message is transmitted.
Thereafter, the messages including the data to be set and stored into the satellite CAT ~hereinafter, this data is referred to as DLL data~ are sequentially transmitted. After com~letion of the transmission of the DLL
data, the p~ent CAT transmits a DLL end message to the satellite CAT.
In response to the reception of the DLI, end message, the satellite CAT
designates the address (in this case, M = 01) of the parent CAT and transmits the message indicative of the result of the DLL to the parent CAT.
When the DLL is executed to all of the satellite CATS among one X
~36~
parent CAT and n satellite CATS, as shown in Fig. 6, the address of the satellite CAT (in this case, the address "FF" to designate all of the satellite CATS is used) is designated and the DLL activation message is transmitted. ~ereafter, the messages including the DLL data are S sequentially transmitted ~o all of the satellite CATS. After completion of the trallsrnission of the DLL data, the parent CAT f*st transmits the DLL
end message to the satellite CAT of the address "02". When lhe DLL
result message is sent from the satellite CAT of the address "02", the parent C~T then transmits the DLL end message to the satellite CAT of the address "03". In this manner, the DLL end messages are sequentially transmitted to the satellite CATS.
Figs. 7a to 7d are diagrams showing a format of each message which is used in the operations shown in Figs. S and 6. Particularly, Fig.
7a shows a DLL activation message. Fig. 7b shows a DLL data message.
Fig. 7c shows a DLL end message. Fig. 7d shows a DLL result message.
A DLL activation message 20 sho vn in Fig. 7a comprises a reception side address, a transmitting side address, and a code "0"
, .
~3~4~
indicative of the DLL a~tivation message. If the reception side address is one of "Ol" ~o "OF", this means that the message is transrnitted to one of the satellite CATS Ib shown in Fig. l. If the reception side address is "FF", this means that the message is transmitted to all of the satellite CATS Ib.
S A DLL data message 30 shown in Fig. 7b comprises a reception side address, a transn~itting side address, a code "l" indicative of the DLL
data message, an address in the memory, a data length, and data in the memory. The address in the memory is the information to designate the storage area in the memory of the satellite CAT. The data length represents the length of data in the memory which is set. The data in the memory denotes the memo~y content which is set into the satellite CAT by the DLL.
A DLL end message 40 shown in Fig. 7c comprises a reception side address, a transmitting side address, and a code "2" indicative of the DLL
end message.
A DLL result message 50 shown in Fig. 7d comprises a reception side address, a transmitting s;de address, a code "3" indicative of the DLL
result message, and a code "O" or "l" representative of the result of the DLL. The code "O" indicative of the result of the DLL means that the DLL has normally been finished. The code "l" dènotes that an abnormality occurred in the DLL
Fig. 8 is a flowchart for explaining the operation of the CAT to which the embodiment of the invention is applied. The operation of the .
.
~3~47~3 ~, , ~, CAT to which the embodiment of the invention is applied will now be described in detail with reference to Figs. 1 to 8.
The CPU 15 first performs the initialization. Then, a guide sentence "Please press a business key" is di~splayed by the display device 12.
S Nex~, the terminal waits until a key is input or the DLL activation message 2n from another CAT is received.
When an operator performs the DLL by using the C~T which is at present being operated as the parent CAT, he or she presses the DLL keys lll of the keyboard ll. In response to the key depression, the CPU 15 displays a guide sentence "Please designate an address" by the display device 12. To designate an address, the ten-keys 112 are operated to input hexadecimal numbers of two digits, and the set key 113 is subsequently pressed. When either one of the addresses "Ol" to 'IOF'' is designated, the CPU 15 allows the display device 12 to display the information indicating that the DLL is being performed. The DlL is executed between one parent CAT and one satellite CAT as shown in Fig. 5. Subsequently, the result of the DLL is displayed on the displ~y device 12 by displaying the characters "DLL", the reception side address "XX", and the code "Y"
indic~tive of the result of the DLL in accordance with this order. If Y is set to "0", this means that the DLL has normally been finished. If Y is set to "1", this means that the abnormali~ occurred in the DI L. If Y is set to "2", this means that the DLL result message SO is not received. After ~3~ 7~
that, the CPU 15 waits until the clear key is input. When the clear key 114 is operated, the operating mode is returned to the initial state.
On the other hand, if "FF" is designated as the reception side address, the CPU 15 allows the clisplay device 12 to display the information indicating that the DLL is being executed. Ihen, the DLL is executed among one parent CAT and n satellite CATS as shown in Fig. 6. After that, the CPU 15 displays the result of the DLL by the display device 12 by displaying, for example, the characters "DLL" and the codes Y2, Y3, ..., Y~
indicative of the result of the DLL in each CAT. If Yn (n -1 to F) is set to "0", this means that the DLL has norrnally been completed. If Y" is set to "1", this means that the abnormality occurred in the DLL. If Yn is set to "2", this means that the DLL result message 50 is not received.
Subsequently, the CPU 15 waits until the clear key is input. When the clear key 114 is operated, the operating mode is returned to the initial state.
The operation of the satellite CAT will now be explained. The operation of the satellite CAT is similar to the foregoing parent CAT until the process for initialization or the state in which the CPU 15 waits fi)r the key input or the activation of the DLL; thereore, the description of this operation is omitted. When the CPU 15 of the satellite CAT received the DLL activation message 20 transmitted through the data transmission line 4, the CPU 15 discriminates whether this message is the DLL activation message to the self CAT or to all of the CATS or not on the basis of the :
\~
reception side address included in the DLL activation message 20. If it is the DLL activation message to the self CAT or to all of the CATS, the information indicating that the DLL is being executed is displayed on the display device 12. Then, the DLL data message 30 sent from the parent S CAT is received. 'rhe transrnitted data is written into the memoIy areawhich is designated by the address in the memory included in the DLL
data message 30. When the DLL end message 40 is transmitted from the parent CAT, the DLL result message 50 is transmitted to the parent CAT
through the data transmission line 4. Then, the CPU l5 allows the display device 12 to display the result by displaying, for example, "DLL OK" or "DLL NG". Next, the CPU 15 waits until the clear key is input. When the clear key 114 is pressed, the operating mode is returned to the initial state.
On tbe other hand, when the DLL activation message 20 transrnitted from the parent CAT through the data transmission line 4 is not the DLL activation message to the self CAT but the DLL activation message to another CAT, the CPU 15 further waits until a key is input or until the DLL is activated.
As described above, according to this invention, a plurality of CATS
are connected to the data transmission line and the data read out of the memory mealls of parent CAT is $ransrnitted to satellite CAT through the data transm~ssion line and written into the memory means in this satellite CA~. Thus, the data or the like can be easily set without passing through any apparatus.
