Control Description
Set the wavelength
WLT_nnnnn,
Sets the output wavelength range.
range
nnnnn
nnnnn,nnnnn="15320, 15670"
:
Outputs the data corresponding to the peak that is detected
within the wavelength range between 15320.0 nm and
15670.0 nm.
The selectable range is from 0.0 to 9999.9 nm. However,
the 2nd parameter must be larger than the 1st parameter.
The default value is 00000, 00000. If set to default, the
output wavelength range is set to the measurement
wavelength range defined by the specifications.
Returns
OK: WLT_nnnnn,nnnnn
when the process is
complete.
Initialize settings
RES
Initializes the settings to default values.
Returns
OK:RES
when the process is complete.
Error status
CHE
Clears all error statuses and alarm output.
Returns
OK:CHE
when the process is complete.
STATUS
SRQ
Returns the operation status.
REQUEST
n=1
: The response format is
STA_n
.
n=2
: Measuring
Warming up (synchronized with the warm up output,
30 to 40 seconds after reset, only SRQ is accepted)
n=3
: Zero calibrating
n=4
: Idle
READ
REA_n
Returns the contents of register A.
REGISTER_A
n=1
: Retransmitting measured data
n=2
: Returns the average count.
AVE_nn
n=3
: Zero calibration value. Returns the number of
elements exceeding the threshold level and the dark
current value and the wavelength of the element
exceeding the threshold level.
ZER_n,nnn,nnnnnn,....
n
:
Number of elements exceeding the threshold
level. 0 signifies that there are no elements
that exceed the threshold level. Data for up
to 10 elements is output even if more than
10 elements exceed the threshold.
nnn:
Dark current value nW
nnnnnn
: Wavelength nm
Data assigned to the e wavelength offset
Approximate conversion of the dark current: 1 nA = 5 nW
n=4
: Returns the offset value.
OFF_
±
nnn
n=7
: Returns the contents of the error.
ERR_n,n,n,....
n=8
: Returns the measurement interval.
TIM_nnn
READ
REB_n
Returns the contents of register B.
REGISTER_B
n=1
: Returns the specified output data.
OUT_n
n=5
: Returns the zero threshold level.
ZTH_nnn
n=6
: Returns the current range value.
RNG_nnn
n=8
: Returns the maximum number of output waveforms.
PNM_nnn
n=9
: Returns the output wavelength limit.
WLT_nnnnn,nnnnn
READ
REC_n
Returns the contents of register C.
REGISTER_C
n=2
: Returns the user-defined optical power compensation
value.
UPR_nnn,nnn,nnn,nnn
n=9
: Returns the threshold value of each optical power
range.
BTH_nnnnn,nnnnn,nnnnn,nnnnn,nnnnn
