When a receipt is generated, a record about a possible future discount is added. The discount identifier is added to the receipt as a barcode. Then, when the barcode is read, the discount is blocked. When a receipt with a discount is generated, the discount transaction takes place. After that, the discount is considered as a used one.
RDS – Receipt discount server. The path to the executable file: bin\rds\rdsserv.exe.
Manager Station Settings
- Go to Service > Stations and Devices. Select a required cash server and add RDS (Receipt Discount Server) Interface to the Drivers tab.
- Add a percentage discount — 100% is allowed — that will be applied when a barcode is read.
- Specify the interface parameters
- Go to Service > Interfaces and create an RDS logical interface. Select RDS (Receipt Discount Server) Interface in the property with the cash server name.
- Open Service > Device Signals Processing > MCR Algorithms. Create an MCR algorithm of the Mask or Prefix type.
Mask example: 9876iiiiiiii?
For barcode prefix 9876: Device type — Barcode, Object — the interface created in the previous paragraph.
Configure the receipt print layout. Add a field, and enter the <barcode XXXX00000000> escape command in it, where XXXX is a prefix, f.ex., 9876. Barcode length shall be 12, zeros shall be at the right. For receipts without discounts, use another layout without such a barcode.
Starting from version 18.104.22.168 <barcode [PrintChecks.StrTag]> shall be entered instead of <barcode XXXX00000000>.
- Select the EAN-13 barcode type in the printer driver settings.
- At the cash server, run preload .\rkeeper.ini. Get intrds.dll from the preload subfolder, and place it along with the cash server (midserv.exe).
Main Section Parameters — [Config]
The default config file RDS.INI is located in bin\rds\ini folder.
Server =RDSServer // server network name
BasePath = .\path\ // path to folder where RDSDB.udb database will be created; usually, folder with RDSSERV.EXE file
StartLang = .\rds.rus // server localization file
RECREATEBASE =0 // if 1, re-creates working base at launch, if –1, does not re-create even if version is changed
TransactionLag =3600000 // time in milliseconds permitted after a discount active period if the discount has already been registered on the order but receipt has not been generated.
Additional Interface Parameters
RDS Server Name = RDSServer — RDS server network name
Default Disc. Code = 0 — default discount code, if limits are not specified, or the first receipt amount is below limits
Percent For Discount = 0 — percent of the first receipt amount that defines the amount limiting the future discount. The maximal value is 100000000 (million first receipts discount).
Active Time(hours) = 24 — time for using discount, in hours
Call Timeout(ms) = 60000 — timeout of calling RDS server network operation, in milliseconds
Bar Code Prefix = 9876 — discount barcode prefix. Same as in printing layout and MCR algorithm mask. Add <Barcode 987600000000> command to the layout (for prefix value 9876). The barcode length shall be 12.
Holder Info () — cardholder info for discount. If empty, the Global ID of the initial receipt will be transmitted.
Min. Disc. Limit 1 = 0 — minimal discount limit. Will be used if above 0 and below Disc. Limit 2. If the first receipt amount is below this limit, Default Disc. Code is used.
Min. Disc. Code 1 = 0 — discount code for first receipts with amounts below Min. Disc. Limit 1 (and below Disc. Limit 2 if used)
Disc. Limit 2 … Disc. Limit 8, Max. Disc. Limit 9 = 0 — discount limit. Will be used if above 0 and below the next limit
Disc. Code 2 … Disc. Code 8, Max. Disc. Code 9 = 0 — discount code for the first receipts with amounts not less than the corresponding limit (and below the next limit if used).
