CHANGING PASSWORD
To change the password, send ENVOY the following text message;
PASSWORD<>OLD password<>NEW password
eg: PASSWORD 88888888 12345678
SETTING and USING the GEO-FENCE
From your cellphone, send ENVOY the following Geo-Fence command:
'SET'
It will respond with a confirmation SMS that it has a new HOME location for the geo-fence.
That’s all…. ENVOY will now send a transgression report if it moves outside the geo-fence radius.
Nothing other than external alarms will be sent while within the new Geo-fence zone. It will of course be
monitoring any bilge levels or security devices all the time. You can at any time send commands and receive
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, ENVOY will send a position report every 5 minutes. You can program ENVOY
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', ENVOY 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 ENVOY GFE (Home) (NEW) Co 17, Sp 0 Kts, R= 200; GD= 0 GT= 5; MGF;

Where R is the geofence radiu
s (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 ENVOY 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
