To Wire Up Your Power Connection
1.
Wire a battery for the computer to the CBatt terminals (TB2 pins 5/6) making sure your
polarity is correct
2.
Wire a second battery, in the 9 to 15 volts range, for the pyro ports. Attach it to the PBatt
terminals (TB1 pin 1/2) making sure your polarity is correct.
Important: DO NOT run a jumper wire from the CBatt+ positive computer battery terminal (TB2
pin6) to the PBatt+ positive pyro battery terminal (TB1 pin1).
To Test the Setup
After all the devices are hooked up, you can test the system. Make sure the shunt plug is correctly
installed and then power the HCX on. The beeper will:
1.
Emit two quick beeps. – The battery is OK and the Cluster/Stage jumper JP7 is enabled for stage
mode.
2.
Emit one beep. – The Cluster/Stage firing device has continuity.
3.
Emit one beep. - The Apogee firing device has continuity.
4.
Emit one beep. – The Low Altitude firing device has continuity.
5.
Emit two beeps. – Nothing is connected to the Programmable terminals.
6.
Then it will pause and cycle the beep pattern again.
If this is not the pattern you hear, refer to
Appendix B
for a list of the status codes.
To Configure your Flight Computer
1.
Connect your flight computer to your personal computer.
o
See the instructions for connecting the flight computer in the
Using FlightView
Software
section of the
User Manual
.
2.
Go into the Configuration menu.
3.
On the Main and Output tabs, change the configuration settings to match your flight plan.
If you have any problems, consult the Configuring your HCX section in the Using FlightView
Software chapter of the User Manual.
4.
Select Upload and Exit.
5.
Disconnect your flight computer from your personal computer.
6.
Power your flight computer off and then on to load the new configuration into memory.
Once you’ve tested your setup by listening to the beep sequence and observing the status LED, you
can either leave it on or turn it off until the rocket is mounted on the pad. The launch sensor is
pretty robust and the shunt plug will not allow the charges to fire.
Important: Do not remove the red shunt plug from JP1/3 until the rocket is mounted on the
pad and ready to launch or until you power it off.
