Using the G-Wiz Flight Computer for More
Advanced Flights
Many people want to start using all of the advanced features of this flight computer right away.
We strongly recommend that you download and read the
G-Wiz HCX User Manual
from the
G-Wiz web site at
http://www.gwiz-partners.com/Downloads/html/docs.html
before you plan
your next flight.
But, we know Rocketeers. This next section briefly describes the steps to set up the G-Wiz HCX
for more complex flight plans. Where you might have any problems, we have tried to point you to
the right section of the
User Manual
to find your answer.
Using the Safety Shunt
Unless you are using motor ejection, we recommend that you
always
include a pyro shunt in your
flight computer setup. When it is properly installed, connecting JP1 and JP3, it protects the pyro
ports from accidentally firing during setup or transport.
You should use the built-in shunt (JP 1/3) any time the HCX is mounted in the rocket in a position
where the shunt plug can be inserted through a hole in the airframe.
In normal use, insert the shunt before you power the unit on, and remove it, on the pad, only after
all other prep work is completed.
Once you remove the shunt, the flight computer will arm the pyro outputs, enabling them to fire
when they are signaled by the configured program.
This picture shows the safety shunt correctly installed into the JP1/JP3 shunt connectors
