Each time you configure or download a Logger via the menu, all available communication ports are checked for Interface Cradles with Loggers. LogTag Analyzer restricts this search to ports that can physically have an Interface Cradle attached, and are also enabled in the communication options.
If you cannot see any interfaces in the access screen, and the progress bar stalls at 0% you should check the following:
- All Interface Cradles have been disabled or disconnected: in this case select “Edit – Options – Communication Ports" and enable the interfaces you wish to communicate to. Plug any disconnected USB or Interface Cradles back into the PC.
- LogTag Analyzer is running twice. If you have accidentally started LogTag Analyzer a second time, the first running instance will prevent the second one from accessing any Interface Cradles. In this case simply close the second copy.
- Communication ports have been enabled that may no longer be present. For example, if a Bluetooth device or a LAN manager device has created virtual COM ports, LogTag Analyzer will still try to communicate to these ports, although they may no longer present. In this case it will take significant time (minutes) for the Operating System to report back that this port is no longer present, and it may seem as if LogTag Analyzer “hangs".
- The USB driver is still being installed from Windows Update. By default the Windows Operating System will check the Windows Update repository if a driver for any newly connected device is available, and download it. Depending on your location, connection speed and operating system it can take a long time for this download to proceed. If you want to speed up this process you can click on the “Installing driver" icon in the notification area and select “Skip obtaining device driver software from Windows Update". Use this option only if you already have LogTag Analyzer installed on your PC.
- There is an issue with the USB driver. You can execute a small utility that will re-install the USB drivers on your computer. This utility can be downloaded from our software page under 'Driver downloads'. You need to make sure you have all USB Interface Cradles disconnected when running the utility. Also, to prevent these drivers from being replaced with a newer version, you need to disable your internet connection when you re-attach the USB Interface Cradles, or disable automatic driver downloading from Windows update.
