information while in either Geo-fence "guard" mode, or after a fence transgression, when in "Tracking" mode
( when the SET command has been issued).
After the initial transgression, RAMV will send a position report every 5 minutes. You can program RAMV
differently, to send other automatic position reports either based on time since the last position (FIX) or
distance from the last Fix, or BOTH. At any time you can request an immediate position report by sending:
'FIX'
This will respond with a current fix. If the GPS receiver is already On and tracking satellites', RAMV will
show (NEW) for the fix. If it is not warmed up, it will send a report showing ' (OLD) ' , while it searches the
sky for satellites and a NEW fix.
Note that the Geo-fence 'SET' command will respond with the new HOME LOCATION and a series of
parameters like:
02:08 RAMV GFE (Home) (NEW) Co 17, Sp 0 Kts, R= 200; GD= 0 GT= 5; MGF; ttp://maps.google/……….
Where R is the geofence radius (m), GD=, the distance between reports and GT=, the time between reports,
after a fence transgression
The factory defaults the Geo-fence radius to 200 meters, and sets up a time-based report for every 5
minutes after the Geo-fence is transgressed. If the monitored asset does not move more than a factory-set
50 meters from the previous reported position, it does not send a new report. It assumes the asset is
stationery. The five minute report is all that is sent until you program it otherwise.
You can change these factory presets with the following commands:
'RAD<> xxxx' where xxx is the new geo-fence RADIUS in meters. The <> signifies a single space. Factory default is
200 m. Minimum is 100meters. eg; RAD 1000
'DIST <> xxxx' where xxxx is the new Distance between reports AFTER a Geo-fence transgression. Factory
default is 0 m (no report) . Minimum is 200 meters. eg: DIST 500
'TIME <> xxx' where xxx is the Time in minutes between reports AFTER a geo-fence transgression. Factory
default and Minimum is 5 minutes. eg: TIM 20
When RAMV sends a position Fix, it delivers the Course (co) in degrees (True); Speed (Sp) in knots; the
geo-fence 'DIST' parameter(GD) in meters; The geo-fence 'TIM' parameter (GT) in minutes; MGF which is
the highest alert geo-fence monitoring mode and lastly a hyperlink to Google Map that contains the Latitude
and Longitude in a degrees and decimal degrees.
Cursor your internet enabled smart phone browser over the hyperlink and click to see the current position
displayed on Google Map. You can copy the link straight onto Google Earth if running on a PC, or use
Bluetooth to transfer the hyperlink from your cellphone to your PC, where you can click on the hyperlink and
view the position on a map.
To Disable the GEO-FENCE function, send the command "NOSET".
OTHER COMMANDS
"FIX" will respond with the immediate GPS Fix. If the GPS is OFF when this is issued, it may take several
minutes to lock a satellite solution and deliver a fix.
"GETSIG" will respond with the GSM 1 to 5 bar measurement and a SSI signal strength Indicator. The GPS
will show the number of satellites being tracked and fixes obtained. You need at least 3 Satellites for a fix.
"INFO" Will respond with the RAMV backup battery %, boat battery Voltage, and temperatures-Ambient,
Maximum recorded and Minimum recorded since last reset command ( 'TEMPR').
"NOFIX" turns OFF the GPS receiver and saves power. Send this to terminate location based services.
