[:IMMediate] Issues an audible signal Vol.2 §21.2.2
:STATe {ON|1|OFF|0} Activates/deactivates the beeper Vol.2 §21.2.3
:STATe? Returns the state of the beeper Vol.2 §21.2.3
:VOLume <value> Sets the beeper volume in a range from 0.0 to 1.0 Vol.2 §21.2.5
:VOLume? Returns the beeper volume Vol.2 §21.2.5
:ERRor Vol.2 §21.8
[:NEXT]? Returns the latest error code and message Vol.2 §21.8.8
:VERSion?

:TERMinal{[1]|2} Information about the LED heads connected to the
LED terminals LED1 or LED2
[:HTYPe]? LED head type identification query. The query re-
sponse is in the format
"<vendor_-
name_string>,<led_head_model_-
name_string>,<led_head_seri-
al_no_string>,<fw_version_ma-
jor_num>,<fw_ver-
sion_minor_num>,<fw_version_sub-
minor_num>"
.
The firmware version indicates the head’s onboard
memory mapping version. A major version number
-1 indicates a custom head without onboard head
info memory. A major version number – 2 indicates
that there is no head connected on the terminal
Sample of a LED with onboard head info memory:

:HEAD
:TEMPerature
[:COUNt]? Get the number of temperature sensor available in
the LED head currently connected to the specified
terminal.
:LABel? [{0|<sensidx>}] Query LED head temperature sensor label.
This is a query with parameter. The optional nu-
meric parameter is the index of the LED head tem-
perature sensor to query. Parameter value range is
0 <= sensidx < senscnt with default parameter val-
ue is 0.
:VOLTage? Query maximum LED forward voltage specified by
the head’s onboard info memory
:CURRent? Query maximum LED forward current specified by
the head’s onboard info memory
:SPECtrum?
Query the spectrum information of the LED head.
Positive values describe the nominal LED center
wavelength in nm. Negative values describe the
color temperature in K. The value 0.0 describes "in-
formation not available"
