The object is filled in for all areas except employee, access card, menu item barcode, and menu item code. The selected object will be sent to the cash station after processing the input device signal.
Specify the parameter in the entry field Fill Edit By Parameter — the field is visible only with the object field.! For processing many objects the entry field in the order edit form is used. For example, when processing a menu item, the quantity is expected to be specified in the entry field. If this property is ticked, then the parameter, received at the time of processing the MCR algorithms, will be processed as if this information has been entered into the entry field. For example, 1234 is written on a magnetic strip; there is a MCR algorithm in the form of a prefix with the 123 prefix, with a Menu Item area, and a ticked Fill Parameter in the Field boxEdit By Parameter box. When swiping the card the parameter will be designated as 4 (as a result of cutting off the 123 prefix). As a result, four portions of the dish will be added.

Menu Item Barcode means searching for a dish using the barcode and adding it to the order. The parameter received after processing the MCR algorithm is compared to the Barcodes menu item attributes and a match is found. The barcode can also include the information about the weight which should also be added to the parameter divided by a semicolon. An There is an example of the MCR algorithm for processing dishes sold by weight in a standard delivery.
Menu Item Code – means searching for the dish using the code and adding it to the order. The parameter received after processing the MCR algorithm is compared to the Code menu item attribute and a match is found.
Currency, Menu Item, Order Type, and Discount – : the respective object is entered specified for these areas. As a rule, when processing such MCR algorithms, the parameter is not important, but it can be used as the entry field information. See Fill in the entry field with the parameter Edit By Parameter.
Interface – : for this area's MCR algorithms it is particularly important to correctly define specify the parameter, as it is the parameter that will be processed by the interface for connecting to other systems.
...
DLL (library) whose name is set in the DLL Name field is responsible for processing the input data.
...
function ( Device: byte; // Device Type DeviceID: word; // Device ID const Src: pChar; // Input Data Indicator (received line) ResBuffer: pchar // An indicator Indicator of the buffer for placing the processed parameter line ): integer; stdcall; |
...
If the input data is of the right kind, the function will return a number between 0 and 255. In this case this number is the length of the ResBuffer result. Numbers outside the 0...255 range indicate that the data does not fit into the algorithm.
Prefix
The algorithm makes sure that checks if the input data starts with the sequence set in the Prefix field. The remaining part is transmitted as a parameter. For instanceexample, the "32167" input data will be correct for the "321" prefix, and the resulting parameter will be "67".
Mask Processing
The processing is based on the mask set in the Processing Mask Input Mask field. The processing rules are as follows: symbols 0123456789+-/=,A..Z are obligatory for the positions they are located in, . a..f – are for text, i..n – — numeral parts of the recognized text for the parameter, r – — restaurant code, ? – — ignored (taken into account for the durationnecessary to control the length), symbols after * are not taken into account. For instanceexample, for the "?bbb=jjj=aaa/iii*" mask and "Q456=000=123/789SOMEINFO" data the mask will work and the resulting parameter will be : 123;456;789;000.
To process items sold by weight, an algorithm which processes processing by mask and the Menu Item Barcode (or Menu Item Code) object type should be added. There is a preset item that you can edit. For instanceexample, the
the 280aaaabbbbb?
data format means that the numbers 280 are control numbers, and that any symbol can replace the ? symbol – the — this symbol has been inserted to control the length. Such an algorithm is a part of the standard delivery. Let's take a look at the following input line:
280aaaabbbbb?
2800198015007
According to the mask, the expression can be broken up asmeans the following:
___019801500 Parameter = 0198;01500
0198 Dish Barcode (or Core Code if the object type is Menu Item Code)
01500 Dish Weight. The dish weight will be divided into the value stated in the BarcodeDivisor parameter (Items Sold By Weight parameter group).
Therefore, if the Menu Item Code or Menu Item Barcode object type is selected, the parameter contains an identity code (barcode) and the dish weight if necessary. If the barcode is for an item sold by weight, the Quantity Coefficient property is ignored.
If there are no identifiers in the input line, that should be transmitted to the parameter, then if the input line matches the mask, the entire input line is transmitted, for example:
Mask: 992=?A??, input: 992=BAYZ. As the input matches the mask, the parameter is 992=BAYZ.
Interface
An interface is responsible for sorting the incoming data. An interface (except internal interfaces) is a DLL meeting certain specifications. Using an interface interface only to process input devices only is unfeasible. If you have an interface used with a system provided by a third party, and you would like the possibility of processing input devices included in it, make a request to the developers.
Script Version 7.0
Enables making a script for processing within the program's interface, so there is no need for compiling own DLL. The processing is based on Innerfuse Pascal Script. The syntax is identical to that of Pascal, but the number of functions is limited and will be listed below. The agent supports the following:
1. Standard types: Byte, Shortint, Char, Word, SmallInt, Cardinal, Longint, Integer, String, Real, Double, Single, Extended, Comp, Boolean, Array, Record, Variant;
2. Variables, constants;
3. Standard expressions: Begin/End, If/Then/Else, For/To/Downto/Do, Case x Of, Repeat/Until, While, With, Uses, Try/Except/Finally Exit, Continue, Break;
4. Functions, procedures, parameters Array of Const, Var;.
Each script has a heading of the following type:
function ( DeviceSignal: Integer; // Device Signal sgXXXX DeviceIdent: Integer; // Device Identifier, see Device identifier var Parameter: String // At input– input — all information, at output – — parameter ): Boolean; |
Returned value:
If TRUE then , the script is considered to have worked correctly, and the parameter is taken from the Parameter variable.
The list of supported functions is given in the RK7Scripts.doc file.
Functions can also be requested called from DLL. To do so it is necessary to create a MCR algorithm of the Script ver.7.0 type and a Script Header area. Such algorithms are not recognition algorithms and are used to set headers for other algorithms. In this case, the Device Type property indicates that this header will be added only to the script of the algorithms, supporting at least one device type from the list supported by the algorithm with the Script Header area. You need to announce In the script field of such an algorithm, it is necessary to specify the external function declaration in the following way in the script field of such an algorithm :
function MessageBox(hWnd: Longint; lpText, lpCaption: PChar; uType: Longint): Longint; external 'MessageBoxA@user32.dll stdcall'; |
In this example:
MessageBox is the Function Name for calling from the
the external script. It indicates that the function is external
MessageBoxA is the Function Name in DLL
user32.dll is the DLL Name
Stdcall points to the means call's specification.
You can now call Now the function can be called from the algorithm script:
