2) Test setup
For external powering
1) Ready to supply 28 volts to pins 13 and 14 of the external power supply connecter,
with the ground running through pin 5 of the OBC debug connector (or to the ASAP
ring if it is accessible).
2) Current limit set to maximum, and run the positive line through a digital ammeter.
3) The EPS ARM plug should NOT be connected.
4) The S-Band ARM plug should be present.
5) When the spacecraft should be powered up, simply turn the power supply on.
For internal powering
1) The external power connector should be left empty. Ready to connect the EPS ARM
plug to turn the spacecraft on.
2) The S-Band ARM plug should be present.
3) When the spacecraft should be powered up then apply the ABF connector, wait for
five seconds (to charge the timer skip capacitor), disconnect it, and then reapply. The
spacecraft should boot-up. (If the last boot-up was within the last 30 minutes then
only one application is necessary as the capacitor should still be charged.
Groundstation
1) Should already be set up internally – don’t change anything.
2) Ensure that the ICOM is connected to COM port 1
3) Ensure that the TNC is connected to COM port 4
4) Turn the power supply on and check all the lights come on
5) Run PCR-100 controller, should see a non-zero signal (noise). If communication is
not possible then a dialogue box will appear to inform
6) Run term.exe and ensure it is set to 56k7
7) Connect and send a test TC, should see the PTT lights come on on the UHF side of the
TNC and the UHF radio
8) Run DTMF.exe and make sure that the audio spectrum is present (noise)
