When operating Spatial FOG Dual at a very high data rate, data can be lost due to the
latency of the FTDI driver. To resolve this problem the latency of the driver should be
reduced by going to control panel → system → device manager → ports and right click
on the USB serial port, then click properties. In the properties window click the port
settings tab and then the advanced button. You then need to change the latency timer
setting to 1ms. Please see the screenshot in Illustration 28.
