JPS60227585A - Serial address lister - Google Patents

Abstract

PURPOSE:To reduce losses in terms of time and to improve the recording accuracy by reading out serial numbers and inner addresses for every terminal device through a personal computer, storing them in a recorder and recording them in a printer. CONSTITUTION:An address reader 14 is connected to an output port 9 of a terminal device 1. Address data inherent in the terminal device is subjected to the waveform shaping, converted into binary signals and supplied to a personal computer 16. A lister reads out a bar-code applied to the device 1 with a light pen, decodes its serial number and stores it on a memory 15. Thus, when address data is collected with respect to the prescribed number of terminal devices, contents built up on the memory 15 are recorded on a magnetic tape recorder 19 and an FF18 in correspondence to the serial number, and printed by a printer 20 if necessary.

Description

[Detailed description of the invention] [Industrial application field]

TECHNICAL FIELD The present invention relates to a serial address lister that serves an OAT V terminal device with one-way communication.

[Prior art 1] Due to the characteristics of the CATV system using one-way communication, data communication can be performed in the downward direction from the center side when providing video signal service. It determines enable/disable, but since there is no return signal (upstream signal) on the center side, it is difficult to obtain information such as whether the terminal is being used legally or whether it has been modified for the purpose of eavesdropping. Can not. Conventionally, terminal devices are inspected periodically, but at that time, the address data of the terminal device is checked by reading out the address data written in the ROM (read-only memory), etc. inside the terminal device. . [Technical Problem] During this work, the operator visually reads the serial number of the 0ATV terminal device and writes it in the correspondence table. Next, the 0ATV terminal is connected to an address reader, etc., and the internal address data of the OA'rV terminal is read and displayed, and the operator visually reads this and writes it into a correspondence table. Since the correspondence table between serial numbers and address data is created manually using this method, there is a problem in that a large amount of time is lost and errors such as entry errors are likely to occur in the creation of the correspondence table. [Object of the invention] The present invention has been made based on the above circumstances, and each C.
The present invention seeks to provide a serial address lister that reads the encoded serial number of an ATV terminal and reads and records the corresponding internal address data.

[Technical configuration of the invention]

For this purpose, the present invention provides a CATV terminal device that receives a video signal and data communication in one direction from a center and has an address unit that includes a key signal for identifying enable and disable for channel selection. , a personal computer that reads the serial number of each terminal device and an internal address of each terminal device in correspondence, and a data medium that records the serial number and internal address as data.

【Example】

Hereinafter, one embodiment of the present invention will be specifically described with reference to the drawings. In the figure, reference numeral 1 denotes a terminal device, which receives video signals from the center side from a branch cable 2. In the terminal device 1, the demodulator 4 extracts the downlink data signal added to the video signal via the splitter 3 and supplies it to the controller 5. The controller 5 receives an address signal from the address unit G that sets a unique address to the terminal device 1, and determines whether TV reception is enabled or disabled based on the signal from the channel selection operation mechanism. When it is determined that it is enabled, the converter 7 is operated to supply the video signal to the output port 9 to the TV receiver vs8. The serial address lister in this embodiment is configured such that a terminal 10 can be connected to the output port 9. Connected to the output port 9 is an address reader 14, in which the data of the unique address of the terminal device is waveform-shaped and converted into a binary signal readable by the personal computer 16. supply Further, the lister is equipped with a light pen 12, which can read the barcode attached to the terminal device, and this barcode displays the serial number of the terminal device. Data read by the light pen 12 is decoded by the barcode reader 13 and input to the personal computer 16. The personal computer 16 waits for an input signal from the barcode reader 13, sends a signal to the address reader 14, turns on the power to the terminal device, and reads the data at the unique address. When the personal computer 1G receives address data from the address reader 14, it records it in the memory 15 in association with the serial number. In this way, when the address data of the terminal devices has been collected for a predetermined number of terminal devices, the memory
The contents stored in 5 are transferred to floppy disk 18 and magnetic tape recorder 1 according to the serial number.
9 and, if necessary, onto a sheet via a printer 20. In addition, in the figure, the symbol @17 is a backup power source.

【Effect of the invention】

As described in detail above, the present invention automatically reads the serial number of each terminal device and, in correspondence with this, reads and records the data of the unique address. Unlike the case where a correspondence table was created, this method has the excellent effect of reducing time loss and increasing the accuracy of recording.
