The tiedown system uses a signal conditioning
board (designed by christian bonilla) that has a pico fuse, voltage
dividing
resistor, and varistor. This feeds the z-world atod board.
The AtoD board has an analog multiplexor,
optional
opamps with unity gain, and an AtoD converter. The signals enter on the
sigConditioning board connector J1 pins 2 thru 17 and exit on J2 pins 2
through 32. The table below shows the signals that feed the signal
conditioning/atod
board.
