Auto-Recovery Methods for PAX Payment Terminals

PAX terminals connected over LAN may receive a new IP address from the network. When this happens, the POS must reconnect automatically to avoid payment interruptions. Franpos provides three Auto-Recovery modes to keep the pin pad online with minimal effort.

1. Serial Number Recovery (SN)

Primary and recommended option.

In this mode, Franpos uses the terminal’s Serial Number to request the latest IP address from PAX Cloud servers. If the device IP changes, the POS updates it automatically.

How it works:

• POS queries PAX Cloud using the terminal’s serial number.
• PAX Cloud returns the most recent IP address.
• POS updates the terminal IP and reconnects automatically.

Fallback behavior:
If PAX Cloud is down or unreachable (which has historically happened), switch to Network Scan by going to

Devices > Payment terminal > Auto recovery method to Network

2. Network Scan

Local network fallback method.

When selected—or when PAX Cloud fails—Franpos scans the local network (LAN) to locate the PAX terminal.

How it works:

• POS scans the local subnet (for example, 192.168.x.x).
• Finds active PAX devices on the network.
• Updates the IP address and reconnects automatically.

Benefits: Works even if PAX Cloud is down.

3. None (Manual Mode)

No automatic recovery.

In this mode, auto-recovery is disabled. If the terminal’s IP changes, the customer must manually enter the new IP address in the payment terminal settings.

How it works:

• No cloud lookup performed.
• No network scanning.
• Customer must update the IP manually.
