Powering up puzzle
#8
Close. B-)

Short pins 5 and 6 of the S1 jumper block to apply power to the system.
Short pins 1 and 2 to provide +5 V to the E-field preamp.
Short pins 3 and 4 to provide +3.3 V to the E-field preamp.
Leave 1 and 2, 3 and 4 open to not power the E-field preamp.

Bad things are likely to happen is you short 1 and 2 at the same time as 3 and 4 or short pins 1 and 3 as doing so connects the +5 V rail to the +3.3 V rail...

The H-field pre-amp is powered directly from the + 5 V rail so is on when ever the system is powered up.
Cheers
Dave.
