1.1 General descriptions

The evaluation kit provides measurement and configuration access to STIM318 IMU. Configuration, graphical result

presentation and save data to file functions are supported. The single voltage supply required for the IMU operation is

provided from an USB port.

This evaluation kit provides the alternative, portable, solution, e.g. for laptops, and is an excellent choice for IMU

configuration and shorter measurement series.

The kit includes a USB-RS422 converter from Future Technology Devices International which is integrated in one of

the communication cable USB connectors.

The USB-RS422 converter cable is a USB to RS422 levels serial UART converter cable, incorporating FTDI’s

FT232RQ USB to serial UART interface IC device which handles all the USB signalling and protocols. The cable

provides a fast, simple way to connect IMUs with a RS422 interface to USB.

Each USB-RS422 cable contains a small internal electronic circuit board, utilising the FT232R, which is encapsulated

into the end of the (communication) cable. The integrated electronics also include the RS422 transceiver plus Tx and

Rx LEDs which give a visual indication of data traffic on the cable.

4.1 USB kit Installation of FTDI serial driver

To install the drivers for the FTDI serial driver under Windows, follow the instructions below:

Connect the USB-RS422 plug to a spare USB port on your PC.

If there is an available Internet connection, some Windows versions will silently connect to the Windows

Update website and install a suitable driver

In the event that no automatic installation takes place, please refer to the set-up guide from FTDI:

http://www.ftdichip.com/Support/Documents/InstallGuides.htm

4.2 Verification and configuration of serial driver

Launch Device Manager. See Control Panel -> Hardware and Sound -> Devices and Printers.

Verify that the driver installation has completed successfully:

Figure 2: COM port assignments for USB cable in Windows 7.

Make a note of the assigned COM port value(s) information. This will be needed later for connecting to the STIM from

the PC software.

Right-click "USB Serial Port (COM<n>)" and select "Properties"
