APRS-21SETTING SmartBeaconingTMEnter Menu mode and access Menu 630 and 631.Set to use [SmartBeaconing] (Menu No.611) with APRSdata transmission.This function optimizes beacon transmission based ondriving direction and speed. Use this function when youwant to track your transmissions, especially for optimizingcrossover beacon transmission intervals.■ Low speed Low speed setting (2 ~ 30 ).When the speed is lower than this, beacons aretransmitted at the time interval specified under SLOWRATE.Note: To select the speed setting of the units, access Menu 626(DISPLAY UNIT 1 - SPEED, DISTANCE).■ High speed High speed setting (2 ~90 ).When the speed is faster than this, beacons aretransmitted at the time interval specified under FASTRATE.)Note: To select the speed setting of the units, access Menu 626(DISPLAY UNIT 1 - SPEED, DISTANCE).■ Slow rate Low speed transmission interval time(1 ~ 100 minutes).■ Fast rate High speed transmission interval time(10 ~ 180 seconds).■ Turn angle Driving direction change, minimum value setting(5 ~ 90 degrees).■ Turn slope Driving direction change, additional value setting(1 ~ 255 (10degrees/speed)).■ Turn time Minimum time delay between each beacontransmission by change of direction. (5 ~ 180 seconds).Note:◆ When Menu No. 602 is set to a value other than [GPS], itoperates at the SLOW RATE.◆ Adjust the Setting values to match the actual driving status.SmartBeaconing Operation:Speed TransmissionIntervalCornerPeggingAbove the HIGHSPEED FAST RATE OperatesnormallyUnder HIGH SPEEDOver LOW SPEED(Only when the setHIGH SPEEDLOW SPEED)The interval iscalculated using thefollowing formula:(Transmission Interval= FAST RATE x HISPEED ÷ Speed)OperatesnormallyBelow the LOWSPEED SLOW RATE Will notoperateTransmission Interval Example:(with LOW SPEED = 5, HIGH SPEED = 70, SLOW RATE= 30 min, FAST RATE = 120 sec)Speed Interval80 120 seconds (2 minutes)70 120 seconds (2 minutes)50 168 seconds (2 minutes 48 seconds)30 280 seconds (4 minutes 40 seconds)20 420 seconds (7 minutes)10 840 seconds (14 minutes)5 1680 seconds (28 minutes)0 1800 seconds (30 minutes)Corner Pegging Operation Example:(with TURN ANGLE = 30°, TURN SLOPE = 24)Speed TURNSLOPETURNSLOPE ÷Speed (1)TURNANGLE(2)TurnThreshold(3)=(1)+(2)60 24 (x10) 4° 30° 34°50 24 (x10) 6° 30° 36°30 24 (x10) 8° 30° 38°20 24 (x10) 12° 30° 42°10 24 (x10) 24° 30° 54°5 24 (x10) 40° 30° 78°• When the value of [Turn Threshold] exceeds 120º, it iscalculated as 120º.< SmartBeaconing™ from HamHUD Nichetronix >
