Figure 7. The DSPEC Pro Display for a
Non-SMART-1 Detector.
The next line shows the current high-voltage setting (HV); the current high-voltage status (ON,
OFF, SHDN [shutdown], or OVLD [overload]); and the shutdown mode (TTL, ORTEC, or
SMART).
If a SMART-1 detector is attached, the DSPEC
Pro displays a line immediately beneath the high-
voltage line; this line is blank for other detector
types (compare Figs. 6 and 7). On the left are the
word SMART and the first 10 characters of the
SMART-1 detector’s serial number. This is the
same value returned by the SHOW_DET_SNUM
command. On the right is the detector tempera-
ture in kelvins.
The next line shows the ID number for this
DSPEC Pro as set by the MCB Configuration
program and displayed in the Master Instru-
ment List (see the MAESTRO user manual for more information on the MCB Configuration pro-
gram and the Master Instrument List).
The last line on the display gives the firmware version for this DSPEC Pro.
