Table 3-2 Shimmer Dock features
The Dock connects to a PC via a USB cable. Whilst drivers for the microSD Card Access should already
exist on your PC, you may need to manually install USB Serial Converter drivers to use the Dock for
programming the Shimmer. You should perform the installation of these drivers before you first
connect your Dock to the PC. Later versions of Windows (e.g., Windows 10) normally have this driver
pre-installed and so manual installation might be necessary.
Warning: If you are using an older version of Windows (typically less than Windows 10) and you
connect the Dock to a PC, do not allow Windows to install the driver automatically.
Note: For more information about the Dock, including troubleshooting, please refer to the Shimmer
Dock User Guide, which can be obtained from the folder \Documentation\Hardware User Guides in
the Shimmer User Resources distribution.
3.2.1. USB Serial Converter Driver Installation
1. The USB Serial Converter drivers for the Dock can be downloaded from the FTDI Chip Drivers
webpage. Download and install the driver to match your operating system.
2. Plug in your Shimmer USB Dock or USB reader. If the reader hasn't been powered recently, you
may get a driver error. Simply unplug and try again.
3. Verify your system settings:
I. From the Control Panel, select Device Manager (in Windows this is found from
Control Panel → System → Hardware → Device Manager or by typing devmgmt.msc in the
Start menu) and expand the USB or Universal Serial Bus controllers entry as shown in Figure
3-4.
II. You should see at least two entries for USB Serial Converter (the other entries will vary with
system configuration and may not match the image above exactly).
