Figure 1-3 Indicator Leds - ARM DSTREAM DS-5 User Manual

When you power-up the DSTREAM unit, the DSTREAM logo on the top of the unit illuminates and the
STATUS LED begins to flash. The STATUS LED remains illuminated to show that DSTREAM is in its
ready state.
The DSTREAM logo flashes for five seconds when you use the Identify tool.
The LEDs representing the DSTREAM debug feature have the following functions:
STATUS
FLASH
TARGET
DEBUG
The LEDs representing the DSTREAM trace feature have the following functions:
TRACING
TRIGGER
DATA
FULL
100955_0529_00_en
USER IO
The STATUS LED illuminates as continuous red if a critical error is detected. You must reboot
DSTREAM before you can continue using it. To do this, press and hold the RESET button for
approximately three seconds, until the STATUS LED turns off.
The FLASH LED illuminates green to denote that the unit is accessing its internal flash storage.
The TARGET LED illuminates when a target VTref is detected through the probe.
The DEBUG LED illuminates green when debug data transfer is taking place.
The TRACING LED indicates that tracing is in progress.
The TRIGGER LED indicates that a trigger is detected.
The DATA LED indicates that there is valid data in the data buffer.
The FULL LED illuminates when a sufficient amount of trace data has been captured to fill the
defined buffer size. The buffer then wraps, and continues to capture trace data, overwriting the
original trace data captured.
