at least one processor operatively coupled with the electrical interface, the user interface, and the electronic memory, the at least one processor being programmed to operate the logger in an automatic logging mode when the plurality of preprogrammed electronic detonators are connected to the electrical interface to cause the logger to:

(i) while the plurality of preprogrammed electronic detonators are connected to the electrical interface, transmit one or more read request messages via the electrical interface without transmitting any delay programming messaging to the plurality of preprogrammed electronic detonators and without requiring user interaction with the user interface,

(ii) while the plurality of preprogrammed electronic detonators are connected to the electrical interface, await responsive messaging from a given electronic detonator of the plurality of preprogrammed electronic detonators without transmitting any delay programming messaging to the given detonator and without requiring user interaction with the user interface, and

(iii) upon receiving responsive messaging from the given electronic detonator while the plurality of preprogrammed electronic detonators are connected to the electrical interface:

obtain electronic detonator data including a serial ID number, a programmed detonator ID and a delay value from the responsive messaging without transmitting any delay programming messaging to the given electronic detonator and without requiring user interaction with the user interface, and

store the electronic detonator data in the electronic memory without transmitting any delay programming messaging to the plurality of preprogrammed electronic detonators and without requiring user interaction with the user interface, and thereafter

(iv) while the plurality of preprogrammed electronic detonators are connected to the electrical interface, repeat (i), (ii) and (iii) for further ones of the plurality of preprogrammed electronic detonators that are connected to the electrical interface without transmitting any delay programming messaging to the further ones of the plurality of preprogrammed electronic detonators and without requiring user interaction with the user interface.

2. The logger of claim 1 , wherein the at least one processor is programmed to cause the logger to:

provide an audible, vibratory or visual indication to the user via the user interface that the given electronic detonator has been logged during operation in the automatic logging mode without transmitting any delay programming messaging to the plurality of preprogrammed electronic detonators and without requiring user interaction with the user interface.

3. The logger of claim 1 , wherein the at least one processor is programmed to cause the logger to:

remain in the automatic logging mode until the user interacts with the user interface to exit the automatic logging mode.

4. The logger of claim 1 , wherein the at least one processor is programmed:

determine whether a serial ID number received in responsive messaging from the given electronic detonator has been previously logged, and if not, to send a verify command to the given electronic detonator to cause the given electronic detonator to update its status flag to prevent the given electronic detonator from responding to subsequent read request messages.

5. The logger of claim 4 , wherein the at least one processor is programmed to cause the logger to:

provide an audible, vibratory or visual indication to the user via the user interface that the given electronic detonator has been logged during operation in the automatic logging mode without transmitting any delay programming messaging to the plurality of preprogrammed electronic detonators and without requiring user interaction with the user interface.

6. The logger of claim 4 , wherein the at least one processor is programmed to cause the logger to:

remain in the automatic logging mode until the user interacts with the user interface to exit the automatic logging mode.

7. A method for logging electronic detonator data of a plurality of preprogrammed electronic detonators connected to a logger that operates in an automatic logging mode and that is incapable of providing sufficient energy to fire the electronic detonators, the method comprising:

(i) while the plurality of preprogrammed electronic detonators are connected to the logger, the logger transmitting one or more read request messages to the plurality of preprogrammed electronic detonators, without transmitting any programming messaging to the plurality of preprogrammed electronic detonators, and without requiring user interaction with a user interface of the logger;

(ii) while the plurality of preprogrammed electronic detonators are connected to the logger, the logger awaiting responsive messaging from a given electronic detonator of the plurality of preprogrammed electronic detonators without transmitting any programming messaging to the given electronic detonator and without requiring user interaction with the user interface; and

(iii) the logger, upon receiving responsive messaging from the given electronic detonator while the plurality of preprogrammed electronic detonators are connected to theft logger:

obtaining electronic detonator data from the responsive messaging, the electronic detonator data including a serial ID number, a programmed detonator ID and a delay value from the responsive messaging without transmitting any delay programming messaging to the given electronic detonator and without requiring user interaction with the user interface, and

storing the electronic detonator data in an electronic memory without transmitting any delay programming messaging to the plurality of preprogrammed electronic detonators and without requiring user interaction with the user interface; and thereafter

(iv) while the plurality of preprogrammed electronic detonators are connected to the logger, the logger repeating (i), (ii) and (iii) for further ones of the plurality of preprogrammed electronic detonators that are connected to the logger without transmitting any delay programming messaging to the further ones of the plurality of preprogrammed electronic detonators and without requiring user interaction with the user interface.

8. The method of claim 7 , further comprising:

the logger providing an audible, vibratory or visual indication to the user via the user interface that the given electronic detonator has been logged during operation in the automatic logging mode without transmitting any delay programming messaging to the plurality of preprogrammed electronic detonators and without requiring user interaction with the user interface.

9. The method of claim 7 , further comprising:

the logger remaining in the automatic logging mode until a user interacts with the user interface to exit the automatic logging mode.

10. The method of claim 7 further comprising:

the logger determining whether a serial ID number received in responsive messaging from the given electronic detonator has been previously logged, and if not, sending a verify command to the given electronic detonator to cause the given electronic detonator to update its status flag to prevent the given electronic detonator from responding to subsequent read request messages.
