How to get help with cash register peripheral preferences

The present invention relates to a method for providing peripheral device configuration help of a cash register, and in particular, when a new peripheral device is installed in a cash register after a built-in peripheral device setting help function is installed in a cash register in advance, or when a new environment of an existing peripheral device is newly set. It is a method of providing peripheral device configuration help of a cash register, which enables the peripheral device to be configured according to the help provided by the register.

In general, a cash register refers to a device used to facilitate information management by processing a variety of data associated with the sale of merchandise to inform the user. It ranges from point of sales system to comprehensively manage the distribution economy such as research. Hereinafter, in the present specification, the term ECR (Electronic Cash Register), which means an electronic cash register controlled by a microprocessor, is used as a broad concept including a low-end cash register to a POS terminal.

In such a cash register, various peripheral devices may be attached to improve the function of the cash register. For example, a printer, a scanner, a customer display, a disk drive, a label printer, and the like may be attached. In order for the peripherals as described above to be connected to the cash register and operate, the variable values must be appropriately set in the environment variables of the peripheral devices such as processing speed, error parity, stop bit, and bit per character. The setup process is quite cumbersome and varied.

Therefore, most of these peripherals include a manual that guides you through the process of connecting and configuring the peripherals when you purchase the device or when you purchase a cash register. Therefore, in the case of attaching a peripheral device to the cash register, the user reads the manual, installs the peripheral device, sets up the environment, or asks the seller of the peripheral device or the cash register to install the device or set up the environment.

In the peripheral device environment setting of the cash register as described above, when the user directly installs, the peripheral device is installed or configured while referring to the manual. The manual referred to by the user refers to the peripheral device installation description or simple environment setting. Although descriptions are given, there are not enough explanations or combinations of how to set detailed environment variables such as processing speed, error parity, stop bits, and bit per character. In addition, when installing a peripheral device through the seller there is a problem that additional installation cost is added or wait for a while to install according to the schedule of the seller.

The present invention has been made to solve the above-mentioned problems, in particular, when a cash register is installed when a new peripheral device is installed in the cash register or a new environment is set in the cash register after the built-in peripheral device help function is built in advance. The purpose of the present invention is to provide a method of providing a cash register configuration help, which can simplify the configuration of the peripheral device by enabling the configuration of the peripheral device according to the provided help.

In order to achieve the above object, a method of providing environment setting help of a cash register according to the present invention includes the steps of: (a) previously embedding a help message necessary for setting a peripheral device in a memory when a cash register is manufactured; (B) determining whether a valid peripheral code is input when a help request code is input and a code of a peripheral device is input; (C) if the input peripheral code is a valid peripheral code, copying help of the peripheral code into a message buffer; (D) sequentially displaying help to input environment variable values to be set according to the setting order; (E) setting an environment variable to the input environment variable value when an environment variable value according to the displayed contents is input; And (f) storing the setting values of the peripheral device in the memory when the steps (d) and (d) for all the environmental variables are completed.

Hereinafter, with reference to the accompanying drawings will be described in detail a method for providing a peripheral device environment setting help of a cash register according to a preferred embodiment of the present invention.

1 is a system block diagram of a cash register to which the method for providing peripheral configuration help of the present invention is applied. As shown in this figure, the ECR system to which the present invention is applied applies the key input unit 20 and the key input unit 20 that generate various mode codes for mode designation signal and money registration, and kisses the received key code. According to the ECR mode, the central processing unit 10 for performing various functions in the designated mode, the ROM 40 having built-in help corresponding to the system operation program and peripheral code, and various data including deposit and withdrawal details RAM 50, which stores the bar code input unit 60 to receive the bar code information of the product, the printer 70 for issuing the customer receipt and various processing results under the control of the central processing unit 10, the central processing Under the control of the device 10, a display unit 30 for displaying various information related to a money transaction or the like and a drawer driver 80 for withdrawing a cash storage drawer when there is a predetermined key operation are provided. It is done by

FIG. 2 is a diagram illustrating a key configuration of the key input unit in FIG. 1. As shown in the figure, the key configuration of the key input unit 20 of the general ECR is a mode switch 21 used to designate a desired operation mode among various operation modes of the ECR, and a desired function among various functions provided in the ECR. A function key group 23 used for execution, a numeric key group 27 used for inputting prices or corresponding numeric codes of various items, and an item key group 25 used for specifying a desired item. The function key group 23 may be configured to include a 'help request' key 23a having a function for requesting help required when setting up a peripheral device.

When the peripheral devices are installed in the cash register as described above, a configuration for defining a model and an interface method is required. The cash register to which the present invention is applied has a built-in help function for setting the environment of these peripheral devices.

3 is a flowchart illustrating a method of providing a peripheral device configuration help of the cash register according to the present invention. As shown in the figure, the cash register to which the present invention is applied has a help message necessary for setting an environment when installing a peripheral device in a system program. First, in step S10, it is determined whether there is an input of the 'help request' key 23a for requesting help necessary for setting the peripheral device. If there is no input of the 'help request' key 23a in step S10, the process proceeds to step S15 to perform a general ECR function, and if there is an input of the 'help request' key 23a, the process proceeds to step S20. Enter the code of the peripheral device that the user enters by referring to the manual. In the next step (S30) it is determined whether there is a peripheral device corresponding to the code of the peripheral device received in step (S20). If the peripheral device code input in step S30 is not a valid peripheral device code, the process proceeds to step S35 and an error message indicating that the peripheral device corresponding to the input code cannot be connected to the cash register is output on the screen. If the peripheral device code input in step S30 is a valid peripheral device code, the process proceeds to step S40 and the help for the peripheral device is copied to the message buffer allocated to the specific area of the RAM 50. In the next step S50, the total length of the message copied in the step S40 is counted, and then the data is written in the variable 'n' defining the entire help line, and the variable 'i' representing the current line is initialized to '0'. . In step S60, it is determined whether the current line is the last line. If the current line is not the last line in step S60, the flow proceeds to step S70 to display a message of the current line. In step S80, according to the content displayed in step S70, the user inputs or selects a specific variable value, for example, a variable value related to a processing speed, an error parity, a stop bit, a bit per character, etc., in the case of a printer. In step S90, the central processing unit 10 of the cash register sets the environment of the peripheral device according to the input variable value. In the next step S100, the variables of the current line are increased by one, and the steps S60 to S100 are repeated for the increased line. When the steps S60 to S100 are completed for all lines, the process proceeds to step S65 in which the setting values of the peripheral devices are stored in the memory.

The method of providing a peripheral device environment setting help of the cash register according to the present invention is not limited to the above-described embodiment, and may be modified in various ways within the scope of the technical idea of the present invention.

According to the method for providing the peripheral device configuration help of the cash register according to the present invention as described above, when a new peripheral device is installed in the cash register after the built-in help function is pre-installed in the cash register or when a new environment of the existing peripheral device is newly set By allowing the peripheral device to be configured according to the help provided by the register, the user can easily configure the peripheral device according to the help provided by the cash register without the help of a seller.
