Abstract
A system, for example an electronic blasting system, in which a command is issued by a master device to all slave devices connected to the system, causing all slave devices that have not been identified to the master device to respond with identifying information and optionally other information pertaining to the slave device.
Claims15
A method of detecting unidentified slave devices in a system including a master device and a plurality of slave devices, comprising the following steps:
- a) providing each slave device in the system with an identification and pre-loading one or more slave device identifications into the master device;
- b) after step a), connecting at least one slave device to the system;
- c) after step b), issuing a detection command on the system from the master device;
- and,
- d) after step c), issuing a response only from any slave devices on the system that have not been identified to the master device, each said response including the slave device's identification.
A method of detecting unidentified slave devices in a system including a master device and a plurality of slave devices, comprising the following steps:
- a) providing each slave device in the system with an identification;
- b) after step a), connecting at least one slave device to the system;
- c) after step b), issuing a detection command on the system from the master device;
- and,
- d) issuing a clock sequence on the system after issuing said detection command, said clock sequence comprising sequential clock pulses correlated to possible identifications of slave devices such that each sequential clock pulse corresponds to a different multiplicity of possible identifications;
- and,
- e) issuing a response only from any slave devices on the system that have not been identified to the master device, said response including the slave device's identification.
A method of detecting unidentified slave devices in a system including a master device and a plurality of slave devices, comprising the following steps:
- a) providing at least one slave device with an identification residing in a fixed memory in the slave device, and pre-loading one or more slave device identifications into the master device;
- b) after step a), connecting at least one slave device to the system;
- c) after step b), issuing a detection command on the system from the master device;
- and,
- d) issuing a response to said detection command from any slave devices on the system that have not been identified to the master device, each said response including the slave device's identification.
