6.1.3 Hardware
– Direct UART Connection
If incorporating the SpacePoint Scout directly into a host system, the UART interface
should be directly implemented. This involves following the set-up instructions
discussed in Sections 4.1 and 4.2, and specifically requires soldering or otherwise
connecting the GND, Vin, TxD, and RxD pins on the Scout to the host system, as
indicated in Figure 3-1.
6.2 Powering Up the SpacePoint Scout
If you are using the PNI CommBoard, connect the CommBoard to your computer using a
USB-to-mini-USB cable. The red and blue LEDs on the CommBoard should light up. Press
the Reset button (SW1) on the CommBoard to ensure the computer is correctly interpreting
your device‟s communication protocol
If the Scout is integrated into a host system and the UART is directly implemented, then
supply power to Vin.
Note: Ensure the SpacePoint Scout is fully at rest when powering up, and that it remains so for at
least 3 seconds afterwards. This is so the gyro bias properly stabilizes during the initial power-on.
