Model and protocol
Note the manufacturer, the full model name, and the transmission protocol. A USB interface alone does not guarantee compatibility.
FiscalNET V3 · PLUS · Weighing Scales
Connecting scales.
The weight is transferred to the point of sale.
Connect a compatible scale via FiscalNET V3 with a PLUS licence and prepare to read the weight in your sales application.
Before connecting.
Data interface
Check whether the connection is made via a serial port, USB with a virtual port, or another interface supported by the configuration.
Sales application
Confirm that the application retrieves the weight from the FiscalNET integration and that the unit of measurement is correct.
Configuration steps.
Prepare the connection
Use the data cable recommended by the manufacturer. Install the adapter or scale driver, if necessary.
Choose the interface
Identify the communication port in the system. Use the confirmed integration configuration for your scale’s model and protocol.
Match the parameters
For serial, copy the baud rate, data bits, parity, and stop bits from the scale’s configuration. There is no universal value.
Check the reading
Test zero, a stable weight, and changes in weight. Check grams/kilograms, decimal places, and the reading mode required by the application.
Validate the sales flow
Confirm that the quantity has been entered for the correct item, then test a disconnection and reconnection.
Questions about connecting scales.
Is any USB scale compatible?
No. USB describes the physical interface, not the weight transmission protocol. Confirm the exact model, communication mode and compatibility of the point-of-sale application before connecting.
What parameters do I use for a serial connection?
Use the parameters from the manual or the weighing scale’s configuration: baud rate, data bits, parity, and stop bits. These must match at both ends of the connection. There is no universal setting for all models.
The weight is read, but the quantity is incorrect. What should I check?
Check the unit transmitted by the scales and that of the item, the number of decimal places, and the conversion in the sales application. Test zero and a known, stable weight before using in sales.
Does the General Guide contain the commands for my weighing scale?
The General Guide describes the integration of fiscal commands, the HTTP API, files, and Android Intent. The communication configuration of a scale is checked separately for each model, using its manual and FiscalNET support.
