LS Central supports fiscal registration through Type A (A-ETax) using a Control Unit. To comply with local fiscal regulations, you must configure the Fiscal Interface Setup for each POS terminal that uses this interface.
To configure the fiscal setup for a terminal:
- Open the POS Terminal Card in LS Central BackOffice.
- Choose Related > Fiscal Interface Setup.
- On the Fiscal Interface Setup page, fill in the required fields based on your setup.
Fiscal Interface Setup for Type A: e-Tax with the Control Unit
Use the following configuration when setting up the A-ETax interface with a Control Unit:
| Field | Description |
|---|---|
| Register Type | Select A-ETax. |
| Out of Order | Turn off this toggle. Enable it only if the POS encounters an error and needs to bypass fiscalization. |
| Hardware Station ID | Enter the POS Serial Device ID, the same as in the Hardware Profile and the Hardware Station Management Portal. |
| Client Registration ID | Enter the 16-digit unique ID assigned to the terminal. |
| Client Organization ID | Enter a valid 10-digit numeric organization ID. |
| POS VAT Codes | Fill in as needed. If this field is empty, fiscal entries cannot be created. |
| Hardware Station must be used | Turn on this toggle. Both Register types need the Hardware Station with the Service device that connects with the LsSweFiscalDevice DLL. |
| COM port | Enter the COM port number that the e-Tax Control Unit is connected to (for example, COM3). |
| Baud rate | Enter the baud rate required by the device (for example, 115200). This value must match the fiscal device’s configuration. |
| Data bits | Specify the number of data bits used in the communication. |
| Stop bits | Enter the number of stop bits. |
| Parity | Define the parity setting used for communication, such as None, Even, or Odd. |
| Flow Control | Choose the flow control method, for example, None, Xon/Xoff, or Hardware, depending on the fiscal device requirements. |
The POS will use the setting from the fiscal setup page per terminal; other settings for the serial device, as in the Device card and Hardware Station, are ignored.
