AS-614 Command and Data Reference

This page presents the commands and packet layouts documented in the AS_614 with AI User Manual, Ver.5.00 Jan.2025.

note

Model-specific reference Do not transfer AS-613 commands such as mreset, rotate, walltilt, presence-mode controls, or exclusion-zone commands to AS-614. They are not documented in the supplied AS-614 manual.

Transport rules

• ASCII commands and data
• Lowercase commands
• Command terminator: LF or CR
• 230400 bps, 8 data bits, no parity, 1 stop bit, no flow control
• Send commands more than 500 ms apart
• Normal command responses begin with = and end with !
• Settings persist after power cycling
• Reset after changing the mode or applying a new configuration
• Initial output after changing mode or restarting with start can contain previous buffered state

Command responses

The manual provides query examples such as:

=15!

It does not define standard error strings or a response-time maximum. A host must retain unknown =...! frames, apply an application timeout, and avoid copying AS-613 error names into an AS-614 parser.

Packet identifiers

Mode	Normal/basic	Alternate	Vacancy/short state
1 Wall position	# coordinate	* zone	#0!, *0!
2 Ceiling position	$ coordinate	~ zone	$0!, ~0!
3/4 Occupancy	< total	> nine zones	<0!, >0!
5 Vital	% no waveform	@ waveform	%0!, @0!
6 Vital + position	& no waveform	? waveform in packet table	&0!, ?0!
10 Raw data	Manual conflict: <...> example or [...] summary	-	Not defined
11 Advanced vital	} no waveform	{ waveform	}0!, {0!
12 Restroom	^	Short and breathing forms	^0!
13 Hospital bed	/ no waveform	\ waveform	/A!, \A!
Command response	=	-	Normally ends with !

Command reference

Flow and reset

Command	Values	Purpose / notes
start	Runtime	Start data output. Buffered state can appear first after stop.
stop	Runtime	Stop output while internal detection continues.
reset	-	Software restart while retaining settings.
hreset	-	Restart equivalent to reconnecting power while retaining settings.
freset	-	Restore all settings to factory defaults. Use only in a controlled workflow.

Mode and configuration

Command	Values	Purpose / notes
mode	1,2,3,4,5,6,10,11,12,13	Select operating mode. Modes 10-13 require the applicable license. Changing mode resets coordinate limits to that mode's defaults.
exten	0, 1; default 0	Basic or extended data. Additional fields depend on the mode.
holdtime	1..10; default 1	Maintain object state during temporary non-detection.
led	0, 1; default 0	0 enables detection LED; 1 disables it.
opt	0..3; default 1	0 none, 1 distance, 2 reflection magnitude, 3 movement magnitude.
outtime	0..3; default 0	0 mode default, 1 real-time, 2 once per second, 3 on data change for occupancy mode.
range	20..150; default 40	Distance threshold for merging nearby detections as one object.
response	0..4; default 1	Initial response: 0 fastest/noise-prone; 4 more noise-resistant and less responsive to small/fast motion.
setnum	Table says 1..5; default 3	Set detected-object count. Not fixed in vital modes. Occupancy section conflicts with this range.
static	0..5; default 0	Enable fixed-object detection to 1-5 m; 0 disables. Z-only result, used in Modes 1-4.
pthold	Use 4..500; default 4	Lower values increase sensitivity/noise. The table also prints a lower limit of 3; verify firmware before using 3.
trace	0, 1; default 0	0 renumbers targets from closest; 1 maintains target numbers.
user	0..65535	Store one user-defined value such as a serial number.
ver	Query	Return firmware identification.
vitalhl	0..2; default 0	Fine-vital level: default, small seated movement, or very low movement/sleep.
wait	3..43200 s; default 15	Interval for no-target status output.
wave	0, 1; default 0	No waveform / waveform. wave 1 outputs 10 times per second.
zone	0, 1; default 0	Coordinate/general output / zone output.

Detection-area configuration

All coordinate command values are in millimeters.

Command	Wall range	Ceiling range	Meaning
xmin	-5000..5000	-4000..4000	Minimum X coordinate
xmax	-5000..5000	-4000..4000	Maximum X coordinate
ymin	-5000..5000	-4000..0	Minimum Y coordinate
ymax	-5000..5000	-4000..0	Maximum Y; one note says ceiling value is ignored/processed as 0
zmin	0..10000	-4000..4000	Minimum Z; wall Z is positive
zmax	0..10000	-4000..4000	Maximum Z; wall Z is positive
alrmin	0..180°	0..180°	Left/right start angle
alrmax	0..180°	0..180°	Left/right end angle
adumin	0..180°	0..180°	Down/up start angle
adumax	0..180°	0..180°	Down/up end angle

The default tables contain the typo adwmzx; the command table and diagrams identify the intended maximum command as adumax.

Debug and inspection

Command	Purpose
help	Output available command types.
info	Output configured detection-area status.

Optional and application-specific commands

Command	Values	Mode / purpose
hbh	300..700 mm; default 550	Mode 13 mattress-top height.
hbw	900..1600 mm; default 900	Mode 13 mattress width.
hboffset	1..9; default 5	Mode 13 bed shift from 20 cm left (1) to 20 cm right (9); 5 centered.
wallside	0,1,2; default 0	Mode 13 bed-to-wall direction: head, left side, right side.
oht	0, 1; default 0	Modes 3/4 occupancy response: normal room dwell or fast corridor passage.
raw	1..8; default 1	Mode 10 selected antenna set.

The manual example misspells wallsiee; the command name is wallside.

Packet layouts

Byte counts include the displayed start and end markers but exclude any trailing CR/LF.

Mode 1 - wall position

#ABBBBCCCDDD!          13 bytes
#ABBBBCCCCDDDEEE!      17 bytes, extended

Mode 2 - ceiling position

$ABBBBCCCCDDD!         14 bytes
$ABBBBCCCCDDDDEEE!     18 bytes, extended
~ABC!                   5 bytes, zone

• Distance packet: target, signed X, optional negative Y, signed Z, reflected power
• Zone packet: target, coarse X zone, coarse signed-Z zone

Modes 3 and 4 - occupancy

<A!                     3 bytes, approximate total
>ABCDEFGHI!            11 bytes, nine-zone distribution

A-I correspond to the three-by-three zone grid. The manual does not define per-zone values above 9.

Mode 5 - vital signs

%ABBBCCDDD!                    11 bytes
%ABBBCCDDDDEEEEFFFGGG!         22 bytes, extended
@ABBBCCDEEEFFF!                15 bytes, waveform

?ABBBBCCCDDDEFFFGGHIII!        23 bytes, waveform

Target; signed X; positive Z; power; vital state; heart rate; breathing rate; optional pulse/waveform.

Mode 10 - raw data

Each selected antenna contributes 128 signed real/imaginary pairs separated by spaces and commas. The manual conflicts on delimiters:

<real imag,real imag,...>      example in Mode 10 section
[real imag,real imag,...]      implied by start/end summary

Do not select one form by assumption. Capture and verify production firmware before implementing the parser.

Parser implementation notes

• Match active mode, start character, zone, exten, and wave before decoding.
• Validate fixed widths, signs, decimal fields, and expected terminator.
• Do not globally assign < and > without checking the active mode.
• Treat initial buffered frames after mode changes or start as non-acceptance data.
• Treat undocumented variants and malformed frames as unsupported input.
• The manual does not define overflow, saturation, unavailable-value codes, target-index lifetime, error-response strings, or maximum response time.
• Keep Mode 10 parsing disabled until real frame delimiters and maximum length are verified.
