A single Spider system would involve up to 84 "munitions," each a small disc with six miniature, single-shot grenade launchers. When a nearby tripwire is triggered, one or all the grenades will fire, depending on the setting.

The disks can also be loaded with plastic balls as a nonlethal weapon, Chaplin said.
Each mine runs on a battery which has a life of 30 days. Once the battery dies, then the mine is rendered useless. There is nothing on how the minefield is controlled. My guess is that they are connected by wires which run back to the control station.
