6.6 Cannot send macro in Macro Commands view
If the
Check macro command syntax
check box is enabled and there is an error message, check
the message and the macro command to see if there is an error in the macro. If there were no
errors, disable syntax check to force sending of the macro.
6.7 Cannot check the syntax for macro command
When using the SCA3000 USB Interface card demo board, the
Check macro command syntax
is
always disabled.
6.8 Wrong output values or axis directions
If wrong sensor type is auto detected, following warning message is shown. Software might then
select incorrect sensitivity value and/or axis directions. This can happen also if incorrect sensor
type was selected manually.

6.9 Installing Java
The demo GUI uses Java programming language, so the Java Runtime Engine (JRE) must be
installed. Usually this is already the case, but if the JRE is not installed, download the installation
package from Java’s website (
http://www.java.com/en/download/index.jsp
), execute the installer
and follow the instructions. Java installation can be tested by typing the command
java -version
to
terminal
. In the Windows Command Prompt this should give an output similar to Figure 43 if Java is
working correctly.

6.10 Installing FTDI drivers
Note: If it is necessary to update the FTDI driver, make sure to uninstall the old driver before
updating to the new one (see Uninstalling the GUI and FTDI driver)
The FTDI driver is needed for communication with the evaluation board via the USB. FTDI drivers
can be found from Windows Update, so Windows might install the driver automatically when the
evaluation board is connected to the USB port. If Windows could not find the driver, manually
browse to Drivers/FTDI folder or download the latest driver from the FTDI website
(
http://www.ftdichip.com/Drivers/D2XX.htm
) and start the installation. See
the FTDI website for detailed installation instructions.
