Fuze setting systems and techniques

A system, comprising:

• a projectile including a fuze having a radome housing at a leading end;
• a fuze setter configured to engage the radome housing;
• a plurality of electrical contact pads on the radome housing, wherein the plurality of electrical contact pads are in electrical communication with a system of electronics internal to the fuze;
• a plurality of electrical contact pins provided on the fuze setter, wherein the plurality of electrical contact pins are positioned to engage the plurality of electrical contact pads when the fuze setter engages the radome housing;
• and
• a loopback resistor integrated with a pair electrical contact pads from the plurality of electrical contact pads.

A method of transferring one or both of power and data from a fuze setter to a fuze, comprising:

• bracketing a selected electrical contact pin of a plurality of electrical contact pins on a fuze setter with a pair of edge detect contacts;
• interrogating the pair of edge detect contacts;
• determining whether the selected electrical contact pin is in contact with an edge of an electrical contact pad of a plurality of electrical contact pads provided on a fuze;
• interrogating adjacent electrical contact pins of the plurality of electrical contact pins;
• locating a loopback resistor connected to two electrical contact pads of the plurality of electrical contact pads;
• determining a location of each of the plurality of electrical contact pads based on the location of the loopback resistor;
• performing electrical commutation to rotate electrical contact pin assignments on the fuze setter to match the locations of the plurality of electrical contact pads on the fuze;
• and
• assigning a signal to each of the plurality of electrical contact pins.
