A system includes a user interface device that is capable of communicating wirelessly with a tool. In one example arrangement, the tool can be a well tool or a tool having one or more explosive components. The user interface device is adapted to send commands to the tool to perform tasks, such as test operations. In one arrangement, the user interface device is a personal digital assistant (PDA) having a graphical user interface (GUI).

Communicating with a tool

A safety system for use with an apparatus lowered into a well includes a power supply and a controller that monitors at least a predefined condition of the apparatus. A switch blocks power from the apparatus until the predefined condition is present. A test system includes a test device that generates a signal having a predetermined characteristic (a certain frequency, for example). A controller detects the signal and enables performance of a test operation when the signal of the predetermined frequency is present.
