Fix RF gun connection errors

Issues with the RF telnet service. Restart RF telnet service. What is stopping the Rf guns from working?

Written by Arthur Ashdown

Your radio frequency (RF) guns can lose connection to DeltaWMS. The most common error messages are:

'Connection could not be established'

'Connection timeout.'

For on-premise customers

If you see either of these errors, the Delta Telnet Server service may need restarting, or may have failed to start following a server reboot.

Follow these steps to restart the service. You may need your IT team to complete this.

  1. Log on to the server where the RF scanners are installed.

  2. Open up Services

  3. Make sure all users are off the scanners and the DeltaWMS application.

  4. Find the COM+ System Application, right-click on this and select Stop.

  5. Once shut down, find COM+ System Application, right-click on this and select Start.

  6. Find the Delta Telnet Server, right-click on this and select Stop.

  7. Once shut down, find the Delta Telnet Server, right-click on this and select Start.

Reboot your RF guns. If the issue persists, contact support with details of what you tried and a photo of the RF gun screen.

For Access-hosted customers (Cloud and Evo)

If you see either of these connection errors, contact support. Our team will reboot the Telnet service on the hosted server remotely. You do not need to take any action on your end.

Contact support and include the following information:

  • A photo of the RF gun screen showing the error.

  • Confirmation of whether the issue affects all sites or a specific site.

  • Confirmation of whether all RF guns are affected or only some.

  • The date and time when the issue started.
