SETTING SmartBeaconingTM Enter Menu mode and access Menu 630 and 631. Set to use [SmartBeaconing] (Menu No.611) with APRS data transmission. This function optimizes beacon transmission based on driving direction and speed. Use this function when you want to track your transmissions, especially for optimizing crossover beacon transmission intervals. ■ Low speed Low speed setting (2 ~ 30 ). When the speed is lower than this, beacons are transmitted at the time interval specified under SLOW RATE. 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 are transmitted at the time interval specified under FAST RATE.) 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 beacon transmission by change of direction. (5 ~ 180 seconds). Note: ◆ When Menu No. 602 is set to a value other than [GPS], it operates at the SLOW RATE. ◆ Adjust the Setting values to match the actual driving status. SmartBeaconing Operation: Speed Transmission Interval Corner Pegging Above the HIGH SPEED FAST RATE Operates normally Under HIGH SPEED Over LOW SPEED (Only when the set HIGH SPEED ʾ LOW SPEED) The interval is calculated using the following formula: (Transmission Interval = FAST RATE x HI SPEED ÷ Speed) Operates normally Below the LOW SPEED SLOW RATE Will not operate Transmission Interval Example: (with LOW SPEED = 5, HIGH SPEED = 70, SLOW RATE = 30 min, FAST RATE = 120 sec) Speed Interval 80 120 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 TURN SLOPE TURN SLOPE
