Fresh KDS must be connected to the same wireless network as your Point of Sale (POS) system. To ensure services can function properly, the following are required:

  1. No Firewall Rules blocking the connection of the devices; ensure network devices are allowed to find each other.

  2. The wireless router has UDP Broadcasting enabled.

  3. TCP ports 80, 443, 9100, and 9101 are open; these ports are used to allow printer transmission and status information.

  4. UDP port 22222 is open; this is used to allow communication and send messages (known as datagrams).


💡 Please note: Networks can be configured in many ways. We recommend that you work with your network administrator/engineer or consult your router's manual for assistance with network ports.
