Fixing Problems Connecting a Till (POS PC) or Back Office PC

When installing an additional PC (a till point or an extra back office PC), you must connect it to your main computer (server) by following the steps for an additional installation.

If you already followed the wrong instructions and performed a server installation instead, follow these instructions to link your PC to a different server.

If you receive an error message while following the installation steps, work through the sections below to resolve the problem.

Step 1 – Make sure you used the correct server name

The server name must be the device name of your main computer (server), not the computer you are trying to connect.

You can find the device name of your main computer by going to:
Settings → System → About

If your main computer is registered (full edition), you can email ROBOTILL Support with the error message and ask them to verify that you are using the correct server name and SQL password.

Step 2 – Check your network and server

1. Confirm that both computers are connected to the same network (same Wi-Fi or LAN).
2. Make sure the network is set to Private on both computers.
3. Ensure that Network Discovery and File Sharing are enabled (go to Settings → Network & Internet → Advanced network settings → Advanced sharing settings).
4. Make sure ROBOTILL is installed and working on the server PC. Open the ROBOTILL Back Office app on the server to confirm it runs correctly.
5. If everything above is correct and you still receive an error, perform a network test.

Step 3 – Change the default SQL port

If you reached this point, the problem is most likely (in about 95% of cases) that the default SQL port is already in use. This can happen if another SQL Server instance or another application is using the same port number.

Follow these instructions to change the SQL Server port number .

After changing the port, perform a network test again using the new port number.

Step 4 – Installation succeeds, but the additional PC has no data

If you entered the correct server name and the setup completes successfully, but the additional PC does not show the same data as the server, it is possible that an unnecessary ROBOTILL SQL Server installation exists on the additional PC.

Follow the steps to uninstall the ROBOTILL SQL Server instance from the additional PC.

Step 5 – Get help

If you followed all the steps above and are still unable to connect the PC, contact one of our resellers. They can assist you remotely or on-site (for a fee).
