The present invention relates to an identification setting device for a terminal device that can give a code in a pseudo manner.

(2) Background of the technology In online systems, a large number of terminals are provided for one central processing unit, and processing data is exchanged between them.
By the way, in this system, various tests are executed when the system is put into operation. In this case, a smaller number of terminals than the number of terminal stations is prepared for testing, and the test terminals are tested by changing the station identification address and machine number designation code and operating them as terminals deployed at hypothetical terminal stations. It is becoming more and more common.

(3) Prior Art and Problems In general, terminals have a pin switch configuration circuit mounted on a printed circuit board for setting the station identification address, machine number designation code, etc., and are built into the back of the housing. There is. Then, the contents of the setting circuit are changed to obtain the desired station identification address and machine number designation code each time a test is performed, but this operation involves inserting a shorting conductive pin between the electrical contacts. It required a very difficult technique and could only be done by specialized maintenance personnel. In addition, it is a very troublesome work and takes a lot of time.

(4) Purpose of the invention This invention is a new system that takes into consideration the above-mentioned conventional situation and that enables changing the station identification address and machine number designation code for test terminals in an easy and short time for online systems. The purpose is to provide a device for identifying and setting terminals.

(5) Structure of the invention Briefly stated, this invention is an identification setting device for terminals in which a station identification address and a machine number designation code unique to each terminal in an online system are externally provided. a first electrical connector connected to an end of a lead wire branched from a signal line of a station identification address and machine number designation code circuit incorporated in the terminal, and fixed to a part of the terminal housing; , a switch circuit for respectively setting the station identification address and the machine number designation code;
and an operating unit that integrally includes a second electrical connector that removably connects the output of the switch circuit to the first electrical connector via a lead wire; The present invention is characterized by comprising gate means for blocking the output of the station identification address and machine number designation code circuit when the second electric connector is connected.

(6) Preferred embodiments of the invention Below, preferred embodiments of the invention will be described in detail with reference to the drawings. FIGS. 1 and 2 show a block diagram and a schematic configuration diagram showing one embodiment of this invention. In these figures, 1 is the terminal TM
This is a printed circuit board installed inside the unit, which carries circuits for station identification address and machine number designation. The setting circuit consists of, for example, 10 switches 10 to 19 that can generate binary signals of about 10 digits,
For example, three digits are assigned to the station identification address and two digits are assigned to the machine number code in order from the most significant digits. In addition, these switches 10 to 19
is constructed to obtain a logic "1" signal by appropriately selecting one of the four pairs of contact holes and inserting a shorting conductive pin into the selected contact hole; Base number “5”,
It emits binary signals of ``0101'' and ``1000,'' which correspond to ``8.'' Reference numeral 2 designates a group of lead wires for inputting the outputs of the switches to a control circuit (not shown). The parts up to now have been installed before, and include the following 10 rotary switches 30-39, decoders 40-49, AND gate groups 50-59, connector 6, and lead wire groups 7-9. is newly added according to the present invention.

That is, 10 rotary switches 30 to 39
and decoders 40 to 49 are connected to the printed board 1
It has the same function as the setting circuit above, and more specifically, the switches arranged on the operation panel KB as shown in the figure output arbitrary decimal signals according to their rotational positions, and the decoders output their respective decoder signals. That is, each outputs a binary numerical signal. In this example, the three switches 30 to 32 on the left side of the upper row are used to set the station identification address, and the two switches 3 on the right side are used to set the station identification address.
3 and 34 are used to set the machine number setting code.
The connector 6 includes a male connector 6A provided at the end of the lead wire group 8 for deriving the outputs of the decoder groups 40 to 49, and a male connector 6A provided at the end of the lead wire group 8 for deriving the outputs of the decoder groups 40 to 49, and
19), and a female connector 6B provided at the end of the lead wire group 9 branched from the output lead wire group 2 and attached to the back plate of the casing of the terminal TM. In addition to the connecting portions of the lead wire groups 8 and 9, this connector also includes an AND gate group 50, which will be described later.
In order to close the gates 59 to 59, a connection 61 is provided to conduct between the +5V power supply and ground.

The ten AND gate groups 50 to 59 are provided at positions before the branching of the lead wire group 2 as shown in FIG. are connected to each of the output terminals of the switches 10 to 19, and the other input terminal is connected to the +5V power supply, and the gate is normally opened to read the output of each switch, that is, the station identification address and machine number code of the terminal TM itself. It functions to output etc.

Next, an example of the operation of the device of the present invention having the above configuration will be explained. First, connect the male connector 6A to the test terminal.
It is connected to the female connector 6B on the TM side, thereby closing each gate of the AND gate group 50 to 59 and invalidating the station identification address, machine number setting code, etc. set in advance for the terminal. Next, the control panel KB
The above rotary switches 30 to 39 are operated as appropriate, and the station identification address, machine number designation code, etc. for designating the terminal of the terminal station to be tested are given to the test terminal from the operation panel. Thereafter, an online test between a desired terminal station/terminal and the central office is executed using the test terminal TM.

One embodiment of this invention has been explained above,
The essence of the present invention is not limited to these embodiments, and various modifications are possible. For example, the decoders 40 to 49 may be provided on the terminal TM side, and are not necessary if the setting circuit installed in the terminal has a decimal configuration.
