  If you receive the message 'this device can work faster' but no Local Area Connection 2 appears on your Walchem Controller, it suggests that the driver in your PC has crashed. This can occur when the Controller Restart button is clicked with the USB cable connected. Reboot your PC. If a blue screen appears on restart attempt, a hard reboot may be necessary. Alternatively, the driver in your PC may be corrupt; in this case, uninstall and reinstall the driver.

Why are my Walchem WDSW100 Accessories not sending emails even though ShoulderTap® is working?
- J
  John WoodsSep 6, 2025
  If your Walchem Accessories are not sending emails but ShoulderTap® is working, the issue could stem from several factors: * The SMTP IP address might be incorrect, or not for an ASMTP server. Verify this information with your email service provider. * Ensure that 'Use ASMTP' is checked and that the ASMTP username and password are correct. * Confirm you have a valid email account set up and that the controller's email address is accurately entered. * Also, verify that the 'Send Email Via' setting is configured to 'Modem'. * Finally, double-check that the recipient email address is correct, and there isn't a general email server problem. Contact your email service provider to check the SMTP IP address.
