Hi. How can we help?

Setting up your Blackbox/Fiscal Data Module

The Blackbox (also known as Fiscal Data Module or FDM) is a fiscal device that signs transactions and orders processed on a cash register system. The Blackbox is only required for businesses from the restaurant and catering industry in Belgium that meet specific federal requirements. For more information on who is required to register with a Blackbox device, please refer to the official Federale Overheidsdienst Financiën website.

Once you have confirmed that you have all the required hardware and that all open orders have been finalized in Lightspeed Restaurant, you may begin setting up Blackbox.

  2. Plug the other end of the ethernet cable into your router.

Now that the Serial-to-LAN dongle has been configured, you can set up the Blackbox for use with Lightspeed Restaurant.

To set up the Blackbox:

  1. Plug one end of the serial cable into the Blackbox.
  2. Plug the other end of the serial cable into the Serial-to-LAN Dongle. 
  3. Insert your VSC card.
  4. Connect the Blackbox to power.
