The terminal identification number data is, for example, 5-byte number data that specifies the CAT2 that transmits the data. The business classification code number data is, for example, 1-byte code number data indicating the business specified by the manually input key of the business keys 22. For example, if the business classification number data is 1", it indicates sales registration; for example, 2", it indicates pre-approval; for example, if it is "3", it indicates inquiry;
For example, 4" indicates a canceled return, and, for example, 5" indicates others.

There are memory changes, memory dumps and memory tests.

The above-mentioned classification code 2 is a code that specifies the internal processing performed by the cluster controller 1.

Classification code 2! For example, if it is 1'', data 1 is device number data consisting of 5 bytes, data 2 is terminal number data consisting of 2 bytes, for example,
Data 3 is, for example, upper transmission speed data consisting of 2 bytes. These data are CAT2 keyboard 1
3 and sent to the cluster controller 1, the CPU 5 stores these data in the RAM 7 of the cluster controller 1. If the classification code 2 is “
2", the CPU 5 reads constant data stored in the RAM 7 of the cluster controller 1 and transmits it to the CAT2, and the CAT2 displays the transmitted data on the display 12. For example, the classification code is "3". At this time, data 1 is, for example, 4-byte data indicating the address of RAM 7, and data 2 is change data consisting of, for example, 4 bytes to be stored at that address.CAT2
When these data are sent to the cluster controller 1, the CPLJ5 of the cluster controller 1 changes the data stored in the RAM 7 based on these data. For example, when classification code 2 is 6°4”,
Data 1 is, for example, 4-byte data indicating the start address of the RAM 7 where data to be dumped is stored, and data 2 is, for example, 4-byte data indicating the number of bytes of data to be dumped from the start address. When these data are sent from CAT2 to cluster controller 1, CPL of cluster controller 1
J5 reads these data from RAM7 and sends them to CAT2.
CAT2 dumps the data sent by printer 11.

For example, when the classification code 2 is 5'', the CPU 5
Perform a memory test on AM7.

FIG. 12 is a diagram showing the message 27 sent from the cluster controller 1 to the CAT 2. In FIG. 12, the message 27 is composed of terminal identification number data, display designation code number data, display data, print designation code number data, and print data.

The terminal identification number data is number data that specifies the CAT 2 that receives the message 27 transmitted from the cluster controller 1, and is, for example, 5-byte data. The display designated hood number data is for instructing that display data should be displayed on the display unit 12 of CAT2, for example, 2
This is byte data. Print designation code number data is C
This instructs the printer 11 of the AT2 to print print data, and is, for example, 2-byte data.

FIG. 13 is a diagram showing a display example displayed on the display 12 of the CAT2 that has received the message 27 and a print example printed by the printer 11 for each classification code 2.

FIG. 2 is a flow diagram for explaining the operation of CAT2 shown in FIG. Next, the operation of CAT2 will be explained in detail with reference to FIGS. 2 to 13.

First, the CPU 16 of CAT2 displays the business key 2 on the display 12.
2 is displayed and waits until the business key 22 is operated. When the business key 22 is operated, the CPLJ 16 performs a process according to the manually pressed key, and when the other key 225 is manually pressed, it then displays a message on the display 12 to the effect that classification code 1 should be input. The screen will be displayed and the system will wait for the classification code 1 to be input. Here, when the operator inputs '99'' from the numeric keypad 23 of the keyboard 13, CAT2 functions as a console for the cluster controller 1, and when any other code is input, it performs processing according to each classification code. .

Subsequently, the CPU 16 displays on the display 12 that the classification code 2 should be input, and waits for the input of the classification code 2. When the operator inputs classification code 2 corresponding to the internal processing shown in FIG. 11 from the numeric keypad 23 of the keyboard 13,
Subsequently, the CPU 16 displays on the display 12 that data 1 should be input, and becomes ready to input setting data. CPU1
6 repeats this loop until data 1 to data 3 are input, and transmits the input data to the cluster controller 1 when the data input is completed.

When the CPU 16 receives the processing results from the cluster controller 1 shown in FIG. 12, it displays display data on the display 12 based on the display designation code and the print designation code.
The print data is printed by the printer 11.

FIG. 1 shows a cluster controller 1 according to an embodiment of the present invention.
FIG. 2 is a flowchart for explaining the operation of FIG.

Next, the operation of the cluster controller 1 according to an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 13.

The CPU 5 of the cluster controller 1 waits until it receives the data from CAT2, and when it receives the data from CAT2, the business classification code included in the received message 25 is, for example, "5" indicating "other". If the business classification code is not "5", the message from the lower level is sent to the host computer 3 via the higher level transmission section 9, and if data is received from the higher level, the message from the higher level is sent. The message is transmitted to the CAT2 via the lower-order transmission unit 10.

If the business classification code is "5", the CPU 5 determines whether the classification code 1 included in the business data 26 is "99°". If the classification code 1 is not "99", it operates as a normal cluster controller, but if the classification code 1 is "99", the CPU 5 subsequently performs internal processing according to the classification code 2.

Here, if classification code 2 is "1", for example, CA
The data 1 to data 3 transmitted from T are set in the corresponding areas of the RAM 7, and the contents of data 1 to data 3 are transmitted to the CAT 2 via the lower-side transmission section 10. If the classification code 2 is II 2 N, for example, the CPU 5 reads data 1 to data 3 from the corresponding area and transmits them to the CAT 2 via the lower-side transmission section 10. If classification code 2 is 1 or "3°", 4-byte data from the address indicated by data 1 is changed to data indicated by data 2 and stored, and the address and contents of the data are sent to the lower transmission unit 10. to CAT2 via. For example, if the classification code 2 is "4", data of the number of bytes indicating data 2 is read from the address indicated by data 1, and the lower transmission unit 1
0 to CAT2. If the classification code 2 is, for example, 5", a memory test is performed and the result is transmitted to the CAT2 via the lower transmission section 10. If the classification code 2 is not one of "1" to "5" is an error, so the error message is sent to C via the lower transmission unit 10.
Send to AT2. When transmission to CAT2 is completed, it waits until data is received from the next lower level.

Effects of the Invention As described above, according to the present invention, when specific data transmitted from a card authentication terminal device is received, internal processing is performed based on the instructions of the specific data, so that card authentication is performed. Since the end group management device does not require any special peripheral devices, its configuration is simple, so the card authentication end group management device has high reliability and can be provided at a low price.
