6.6 Application Software – 1094B Utility

Using USB-to-Serial Adapters
If you are using a USB-to-Serial adapter, you may want to check which COM port Windows is
using. If for some reason 1094B Utility software does not connect with the 1094B, you may want
to check it. By using this method, you should be able to verify or reassign the COM Port being
used by the USB-to-Serial adapter to an unused number.
Identifying COM Port Using Windows Device Manager
To check this, you will need to go to
My Computer
>
Manage
>
Device Manager
>
