Details

A properly functioning POS setup requires both physical infrastructure and network connectivity.

Physical requirements

For a typical POS setup, the following minimum provisions are required:

• Minimum 2 available network connections (RJ45 socket) within 1.5m from the POS

  • 1 for the POS system

  • 1 for the payment terminal

  • (optional) 1 for the receipt printer

• Minimum 3 available 230v Schuko power outlets within 1.5m form the POS

  • 1 for the POS system

  • 1 for the payment terminal

  • 1 for the receipt printer

Network requirements

For proper operation, both the POS system and the payment terminal must have access to the network and the internet.

The following requirements apply:

• Active network connections (RJ45) with internet access must be available.

• DHCP with a reservation based on MAC address is preferred.

• If static IP addresses are required, the following details must be available:

  • IP address

  • subnet mask

  • gateway

  • DNS server

• If MAC filtering or port security is enabled, the MAC addresses provided by us must be allowed in advance.

• TCP port 8011 must be open for communication between the POS system and the payment terminal on the LAN.

• For remote management of the POS system, outbound traffic to our management servers over TCP ports 443 and 5494 must be allowed.

Web & content filtering

Important: If web filtering, SSL inspection, or other content filtering is applied on the network, we cannot guarantee proper functioning of the POS setup.

• Update services must be reachable: Windows, Android, and Sunmi OS update servers (no SSL interception).

• Cloud services must be accessible without interference: Google and Cloudflare (used by our systems).

• If web filtering is in place, please inform us in advance so we can assess impact and provide domains/addresses to allowlist if needed.
