Command Syntax Description
D# Set Relay Make Time D#make Specify how long to wait after closing a channel relay before
reading valid data, where make is the number of 520.833
microsecond intervals.
E End Calibration Mode E Terminate Calibration Mode
E? Error Status Query E? Returns present error condition of the unit with one of the following
error codes:
E000 - No error has occurred.
E001 - Invalid device dependent command (IDDC).
E002 - Invalid device dependent command option (IDDCO).
E004 - Channel configuration error.
E008 - Calibration error.
E016
- Trigger overrun.
E032
- Open TC or Range Error.
E128 - Command conflict error.
F Set Data Format Fengr,
format
Configure the input and output formats.
engr converts the raw data to the engineering units that you
prefer to work with. Valid options are: 0 - degrees Celsius
(default),
1
- degrees Fahrenheit,
2
- degrees Rankine,
3
-
degrees Kelvin, and 4 - Volts.
format places the readings in a format that you prefer to work
with. Valid options are: 0 - Engineering Units (default), 1 -
Binary (Low Byte/High Byte), 2 - Binary (High Byte/Low Byte),
and 3 - Counts (ASCII).
F?
Query the data format.
F# Set Burst Mode
Frequency
F#freq Select burst mode sampling frequency where freq is a real
number and where 38.5 < freq < 20000.0 Hertz (default).
G Calibrate Channel Gain Gchan,
type
Calibrate the correction gain constants for given option card where
chan is the channel number such that
1
<
chan
<
max
,
where max = 128 for NetScan.
The chassis is chan = 0 .
type is the channel type.
H Calibrate Channel
Offset
Hchan Calibrate the correction offset constants for given option card
where chan is the channel number such that
1
<
chan
<
max
, where max = 128 for NetScan.
The chassis is
chan = 0
.
I Set Scan Interval Inorm, acq Set the two configurable scan intervals of the unit where
norm
and acq are the normal and acquisition scan intervals which
have the form: hh:mm:ss.t where hh is hours, mm is
minutes,
ss
is seconds, and t is tenths of a second.
I? Query scan interval selection.
I# Digital Input Stamping I#state Specify whether or not digital input stamping will be enabled.
state may have either of the following values: The default of
0 , which disables digital input stamping, or 1 to enable digital
stamping.
J
Calibrate Cold Junction
Offset
Jchan,
type,
temp
Calibrate the cold-junction offsets for cold-junction compensation
of the thermocouple signals where
chan
is the channel number
such that 1 < chan < max ,
where max = 128 for NetScan.
type is the thermocouple channel type.
temp
is the reference temperature currently being applied to the
selected channel, with the form nnn.n in degrees
º
C.
K Enter Calibration Mode Kkey Enter Calibration Mode if the keyword (or password) is correct,
where key is the keyword in the form of a 5-digit number
nnnnn . Therefore the password can be no longer than 5
characters.
K? Query
Kkey
as defined above.
