Failure while booting CH2
If you start your CH2 system and you get a message similar to: "Could not turn off CH2. Turn off power and then back on to all CH2 boxes", followed by: "No CH2 tester found. Check USB connection to tester", then the problem is caused by the USB driver being in a state that the easy-wire software is not able to resolve.
The easiest option is to restart your PC. If you still get the error after a re-start, you will need to change the COM port that the Silicon Labs driver is using.
To do this:
- Right click on 'My Computer' and select 'Manage'.
- Select 'Device Manager'.
- Expand "Ports (COM & LPT)".
- You should have an entry "Silicon Labs CP210x USB to UART Bridge (COM x)". Right click on this port and select 'Properties'.
- Click the "Port Settings" tab.
- Click "Advanced".
- Click the drop down box and select another COM port that is not in use. Click 'Ok' until you are back to the "Device Manager".
- You should now be able to restart easy-wire and have the CH2 connect.
