Appendix A API Commands

	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,	Configure the input and output formats.
		format	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	F#freq	Select burst mode sampling frequency where freq is a real
	Frequency		number and where 38.5 < freq < 20000.0 Hertz (default).
G	Calibrate Channel Gain	Gchan,	Calibrate the correction gain constants for given option card where
		type	chan is the channel number such that
			1 < chan < max,
			where max = 128 for ChartScan/1400.
			The chassis is chan = 0.
			type is the channel type.
H	Calibrate Channel	Hchan	Calibrate the correction offset constants for given option card
	Offset		where chan is the channel number such that
			1 < chan < max, where max = 128 for ChartScan/1400.
			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	Jchan,	Calibrate the cold-junction offsets for cold-junction compensation
	Offset	type,	of the thermocouple signals where chan is the channel number
		temp	such that 1 < chan < max,
			where max = 128 for ChartScan/1400.
			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.
