HMR3000

SENSOR PRODUCTSDigital Compass ModuleHMR3000lectronic compass module that provides heading, pitch and roll output for navigation and guid-ance systems. Honeywell’s solid state magnetoresistive sensors make this strapdown compass both rugged and reli-able. This compass provides fast response time up to 20Hertz and high heading accu-racy of 0.5° with 0.1° resolution.EFast Response TimeBuilt with solid state magnetic sensors and no moving parts improves response time,allowing faster updates compared to gimballed fluxgates.Small SizeAvailable as a circuit board 1.2 x 2.95 inches, weighing less than one ounce, or in an aluminum enclosure.Low Power Operates with less than 35 mA, allowing for long operation with a battery.High Accuracy Accuracy better than 0.5° with 0.1° resolution for critical positioning applications.Wide Tilt RangeTilt range of ±40° for both the roll and pitch allows operation for most applications.Hard Iron CompensationCalibration routines to compensate for distortion due to nearby ferrous objects and stray fields, such as vehicles.User Configurable FeaturesUser settings of baud rate, update rate, output format, units, filter settings, deviation angles, alarms and warnings are stored internally in non-volitile memory.2HMR3000SENSOR PRODUCTSThe table shows pin assignments for the 9-pin D-shell connector. Power input can be either regulated 5V dc or unregulated 6V to 15V. Only one of the two power pins (9 or 8) should be connected in a given installation.INTERFACE SIGNAL DESCRIPTIONS(1) Absolute maximum ratings.(2) Sink current requirement; 200 (Typ) 400 (Max) µA.(3) Open input = high logic state.CommunicationHMR3000 communicates with an external host via RS-232 or RS-485 electrical standard through simple ASCII character strings. ASCII characters are transmitted and received using 1 Start bit, 8 Data bits, (LSB first, MSB always 0), no parity, and 1 Stop bit. Baud rate is user configurable to 1200, 2400, 4800, 9600, 19,200 or38,400. HMR3000 responds to all valid inputs received with correct checksum value.Compass OutputHMR3000 can output three NMEA standard sentences,(HDG, HDT and XDR), three proprietary sentences(HPR, RCD and CCD), and an ASCII heading output for a digital display. HDG, HDT and HPR are the mostcommonly used sentences; the formats are given below.$HCHDG, Heading, Deviation, Variation$HCHDG,85.5,0.0,E,0.0,E*77$HCHDT, Heading, True$HCHDT,271.1,T*2C$PTNTHPR, Heading, Pitch and Roll$PTNTHPR, Heading,Heading Status,Pitch,Pitch Status,Roll,Roll Status*hh<cr><lf>$PTNTHPR,85.9,N,-0.9,N,0.8,N*2Ce m a N t u O /n I n i P n o i t p i r c s e D p y T )1(n i M )1(x a M s t i n U B /D x T t u O 2584-S R /t u o t i m s n a r t 232-S R —81-81c d V A /D x R n I 3584-S R /n i e v i e c e r 232-S R —81-81cd V D N G n I 5n o m m o c l a n g i s d n a re w o P —V 51-6n I 9t u p n i r e w o p d e t a l u g e r n U 51–6003c d V V5n I 8tu p n i r e w o p d e t a l u g e R %5±505.7c d V )2(b i l a C /r e p O n I 1)e t a r e p O =n e p o (t u p n i )3(e t a r b i l a C /e t a r e p O 5–002-02c d V )2(p o t S /n u R n I 6)n u R =n e p o (t u p n i )3(p o t S /n u R 5–002-02c d V )2(p e e l S /y d a e R n I 4)y d a e R =n e p o (t u p n i )3(p e e l S /y d a e R 5–002-02c d V )2(t e s e R /t n o C nI 7)e u n i t n o C =n e p o (t u p n i )3(t e s e R /e u n i t n o C 5–002-41cd V3HMR3000SENSOR PRODUCTSSPECIFICATIONS4.Typical5.Meet or exceed .*Device orientation not to exceed 75°during operation or storage—may cause temporary loss of accuracy.re t e m a r a P eu l a V st n e m m o C gn i d a e H )1(y c a r u c c A )2(S M R °5.0<SM R °5.1<°02<t l i T ,°05<p i D *°02<t l i T ,°57<p i D *)4()3(y t i l i b a t a e p e R °3.0±n o i t u l o s e R °1.0st i n U sl i m /s e e r g e d e l b a t c e l e s r e s U ll o R d n a h c t i P e g n a R °04±y c a r u c c A °4.0±°6.0±°02<t l i T t l i T >°02*)4()3(y t i l i b a t a e p e R °2.0±n o i t u l o s e R °1.0st i n U sl i m /e e r g e d e l b a t c e l e s r e s U )3(d l e i F c i t e n g a M e g n a R c i m a n y D xa m s s u a G 0.1±eg n a r s s u a G 5.0±no i t u l o s e R s s u a G m 1)4(l a c i r t c e l E eg a t l o V y l p p u S d e t a l u g e r c d V 0.5de t a l u g e r n u c d V 51-6re w o P cd V 6@A m 53A m 31Am 0.2n o i t a r e p o l a m r o N e d o M P O T S ed o M P E E L S ec a f r e t n I l a i r e S 232-S R 584-S R xe l p u Df l a H e t a R d u a B sp b 00483o t 0021d r a d n a t S 3810A E M N se d o M e t a d p U s u o u n i t n o C d e b o r t S e c n e t n e s r e p z H 02o t n i m /1g n i g a r e v a e l b a t c e l e s )4(l a c i s y h P t h g i e W )g 22(z o 57.0)g 29(z o 52.3y l n o d r a c t i u c r i C de s u o H sn o i s n e m i D 067.0x 59.2x 2.188.0x 2.4x 5.1dr a c t i u c r i C ss a p m o c d e s u o H )5(t n e m n o r i v n E p m e T g n i t a r e p O C °07o t 02-er u t a r e p m e T e g a r o t S C °001o t 53-k c o h S p o r d h c n i 034.615M T ;E 018-D T S -L I M no i t a r b i V z H 0002-02si x a /s r h 2m o d n a R 4.415M T ;E 018-D T S -L I M gn i r u t c a f u n a M B C P 2106C P I yl b m e s s A 016C P I re t t e b r o I I s s a l C 1.Heading accuracy assumes the Earth’s magnetic field is only disturbed by hard iron fields, and has been compensated through calibration.2.Calculated values.3.Guaranteed by characterization or design.Honeywell reserves the right to make changes to any products or technology herein to improve reliability, function or design.
