Post Activation Tests

Do these immediately to catch issues before trading:.

  1. $0.01/Test Sale: Run a small purchase (or training/test mode if available). Check:

    • Transaction completes on the terminal.

    • Receipts print from the expected device (POS or terminal) per your configuration.

  2. Also test the Void/Refund test to confirm reverse flows.

Troubleshooting (straight talk)

  • Device never connects: 99% of the time it’s a wrong IP, blocked port, or wrong credentials. Verify each. Ensure the terminal has a static IP.

  • Timeouts at authorisation: Increase Time Out to 60 s and check for packet loss (switches/Wi‑Fi bridges cause grief—use wired LAN).

  • Receipts not printing where expected: Align Use Embedded Receipts with Print Customer Receipt. Don’t enable both terminal and POS printing unless that’s intentional.

  • Tipping not offered: Confirm Enable Tipping is ticked and that your merchant account supports tips.

Change control & rollback

  • To disable without deleting: Edit the device and tick Inactive.

  • To remove: Select the device in the list → Delete Device.

What to capture in your ticket (if you need help)

  • Venue/Store name & Till/Workstation.

  • Terminal make/model & IP address.

  • Screenshot of the New Device window showing DLL, Class Name, and Device Settings.

  • Exact error text from POS.
