f Flag: true flag (tf) is non-zero (–1); false flag (ff) is zero. TRUE ( ® tf ) FALSE ( ® ff )

&CHANNELS Use Huron default channel names.

old-name RENAME new-name Rename channel.

f n BIT-OUT Bit n of DOUT channel set to f.

n BIT-INP Bit n of DINP channel; returns f.

n BIT Returns nth bit set; others 0.

n SDOUTREG ! Write n to DOUT register.

SDINPREG @ Read DINP register; = DINP DATA

.FLOWS Output flows continually, with units.

COUNTS ( ® un ) Unsigned counts of FREQ IN.

.FREQ Output continually frequency of FREQ input channel, in Hz; 20 Hz to 500 kHz; for 50 ms.

n PULSE n = 0: PG0; 1: PG1; 2: PG0 and PG1; pulse duration = 1/sample-rate.

n .PULSE Continual PULSE output.

n FIRE Relay on (DOUT7) for > n deciseconds.

± % n PCM ± %: –100 to 100; PCMn channel.

f STROBE Sets digital connector STROBE line to f (TRUE or FALSE); for multiplexing DOUT high-byte on I/O bus or address strobe.

/AS Low-going pulse for address strobe.

channel .MEAS Continuously output processed value and unit of channel.

channel .LMEAS Output linearly-corrected (gain and offset) channel data continually.

channel .DATA Continually output raw data (A/D converter counts) of channel.

MEASURE, LMEASURE, and DATA return single value; output MEASURE and LMEASURE with .VAL - outputs value and unit.

&SCH Clear schedule; no channels in frame.

sample-rate offset channel SCH Schedule a channel (0-24) at sampling rate in Hz; starting at frame offset (0-199); acceptable sampling rates are those that divide 200 Hz: 200, 100, 50, 40, 25, 20, 10, 8, 5, 4, 2, 1

channel UNSCHEDULE Unschedule channel.

.%DAS Percentage of data acquisition rate used.

SCH-GEN Configures a general schedule.

&UNITS Set Huron default units.

unit channel UNIT Set unit of channel to unit.

Unit words: s ms mA mV V psi bar atm kPa degF degC m/s^2 g0 ft/s^2 N lbf Hz kHz ft^3/min cc/s l/min NO-UNIT (no text)

unit .$ Outputs text string of unit.

gain channel GAIN where gain is one of: x1 x10 x100 x1000 Range: 4.1 V fs, 0 V zs input

channel TRANSDUCER transducer Sets channel to transducer type. Built-in types are: LINEAR BRIDGE DIGITAL TCJ TCK RTD100 RTD1K AD22100

&TRANSDUCERS Set default transducer types.

&PROC Set Huron default processing based on transducer type.

channel PROC proc-word Set processing word for channel.

channel IS-BRIDGE-SUPPLY Sets bridge- voltage channel in BRIDGE-SUPPLY. Default bridge supply channel is VBRIDGE (channel 7).

channel .RES Ohmmeter: lower resistance of channel, in W . Upper resistance to bridge supply is RBR = 4 kW . Change range setting with GAIN.

channel CAL transducer One or two-point calibration of channel for transducer type. For one-pt. (gain) calibration, use same input values for both points; for 2-pt. (gain & offset) cal., use widely different values in input range.

.CAL Output calibration parameters to display or capture as a text file. Upload file to Huron to reinstall calibration parameters.

ERASE Fill data recorder memory with hex FFs.

RECORD ON Turns recorder on.

RECORD OFF Turns recorder off.

PLAYBACK Outputs recorded data, processed and with subframe line format:

FULL-SUBFRAME OFF or ON If off, omits channel name and unit in subframe output format.

.%LOG Continually output percentage of recorder memory filled by data.

.LOGTIME Output recording time for existing schedule.

&TELEM Turn off telemetry for all channels.

channel TELEMETERED Turn channel telemetry on to record and telemeter it.

TELEMETRY ON or OFF Turn telemetry on/off; TELEMETER outputs telemetry frame. (See PLAYBACK for format.)

TELEMETER Send the telemetry frame of the next channel.

channel UNTELEMETERED channel telemetry off.

deciseconds SET-TIME Sets clock time in signed (± ) 0.1 second units.

.TIME Clock display of TIME continually.

&CONFIG Default configuration; schedule, calibration and processing unchanged.

.CONFIG Output table showing configuration parameters (settings) of all channels.

RESTART restart-word Set restart mission-program recovery word to be re-run in case of hardware reset.

Restart: Push the reset button. The word set by RESTART is run. A computing failure during execution of a mission will allow the watchdog timer to time out and restart the mission word.

MWD-ENABLE Mission watchdog enable. Set MWD to true (–1) at less than 1 s intervals; else, restart.

n NODE text line Send text line to network node n. Use with RS-485. DINP5-7 set node number in NODE#. Initialize using NETWORK in restart word.
