Internally, the Dock also contains a DIP switch, which is used to ensure compatibility with legacy
devices. Your Dock will ship in the appropriate configuration for the version of Shimmer hardware
that you have ordered. However, if you want to change the configuration to use it with a different
hardware version, you may do so by opening the Dock enclosure. This involves removing the black
rubber feet from the underside of the Dock to reveal four screws which should be removed before
opening the plastic.
The valid DIP switch configuration options are listed in Table 1-2 and illustrated in Figure 1-2. Users
of Shimmer3 should not change the configuration from that recommended below. Users of
Shimmer2/2r should use the “legacy configuration” for most purposes (e.g. programming firmware
and SD card access). In the event that problems are encountered accessing the SD card for
Shimmer2/2r, which can occasionally occur due to driver incompatibility issues on certain PCs, the
“SD card access only” configuration should be used. Note that in this configuration, programming of
the Shimmer is not possible.

The Dock connects to a PC via a USB cable. Whilst drivers for the microSD Card Access should already
exist on your PC, you will 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.
Warning: If you connect the Dock to a PC do not allow windows to install the driver automatically.
1.1. USB Serial Converter Driver Installation
1. The USB Serial Converter drivers for the Programming Dock can be downloaded from the FTDI
Chip Drivers webpage (see Figure 1-3). Download and install the driver to match your operating
system.
