System States
Availability of the Digital Sonifier’s functions depends on the system state. The ‘normal’ state of the system for
most users is the Run or Ready mode. Some remote terminal commands are noted where appropriate (com-
mands have the format of an ‘!’ followed by upper-case letter or letters, i.e. !TS for the Test command). These
commands are also summarized in the Remote Terminal section found on page 6-35. The possible system states
include:
• Power-Up: The system enters the Power-Up state when the power switch is turned on. The fan starts to
run, and the system then enters the Self-Diagnostics state.
• Self-Diagnostics: In this state, the system performs hardware and software checks on itself. The front
panel display shows several diagnostic displays (indicating which step in the self-diagnostics it is in) and
the front panel LEDs will illuminate as a visible test. After it successfully completes this system check, it
enters the Ready state.
• Ready: In the Ready state, the system is waiting to begin an experiment, and it can accept parameter
settings that you enter through the keypad or the remote computer or terminal. The front panel display
