Stopping Cablecast Device Control

Before beginning the upgrade we will disable Cablecast Device Control to prevent Cablecast from attempting any serial communications during the upgrade. Its also important to turn off any other software that might be performing serial communications. To disable Cablecast Device Control:

  1. Right Click on My Computer 
  2. Select Manage
  3. Select the Services panel on the left 
  4. Find and select CablecastDeviceControl in the list of services.
  5. Click Stop with the Cablecast Device Control service selected to disable the service.

 

Uninstalling Existing Drivers

Next, we will uninstall the current drivers:

  1. Right-click My Computer 
  2. Select Manage
  3. Navigate to Device Manager
  4. Expand the Multi-port serial adapters node
  5. Right-click ESU2-400 Eight RS-232/422/485 Serial Ports 
  6. Select Uninstall
  7. Check Delete the driver software for this device in the confirmation window that appears
  8. Click OK to uninstall the Quatech drivers.
  9. Once the drivers are uninstalled, right-click the computer name at the top of the device list and choose Scan for hardware changes. This will rediscover the Quatech device without the drivers installed. The scan can take a minute or two to complete. A warning that the system was unable to install the device correctly may pop up when you rescan. It is safe to ignore the message unless it comes up after the new driver has been installed.

Check your Cablecast configuration to confirm that the device and router port assignments are still configured correctly. Contact support@trms.com if you need assistance reconfiguring Cablecast.
