Abstract

For use in a system having a master device (40) and slave devices (20) (e.g., an electronic blasting system) and utilizing an automatic detection process that causes any slave devices (20) that have not previously been identified to the master device (40) to identify themselves to the master device (40), an enhancement to the detection process employs at least a second discriminator (61) to detect superimposed responses from simultaneously responding slave devices (20), and a 'deconvolution' algorithm in order to ascertain their identities.
