Use Accel to detect motion:  If enabled, the unit will use g-force readings to detect when the 
unit is moving, rather than using the OBD port (if enabled) or 
GPS Stop/Start Speed settings. See section 6.3 for details. 
Note: firmware versions 4.79 to 4.89 have a bug where 
enabling this setting causes invalid speed readings. It is 
highly recommended to disable this option when using 
these firmware versions. 
Status Reports:  Controls the interval for sending status reports, which contain 
odometer and engine hour counters as well as other 
accumulated values. Set to zero to disable. 
Waypoint Reports:  Enable Waypoint alerts. 
Heading Change:  If set greater than zero, position reports are generated when 
unit heading changes by this value. 
Heading Time:  Heading must change for more than this period to trigger report. 
Max Idle Time:  Send report if unit stops moving for this period while engine is 
running. 
Send Tow Alerts:  Send event when vehicle motion is detected for at least “Start 
Time” duration and IGN is off. 
Engine On Battery Voltage:  Assume engine is running when input voltage exceeds this limit. 
Low Battery Voltage:  Alert will be triggered when battery voltage drops below this 
level for 20 seconds. Alert will not retrigger until voltage has 
risen 1 V above limit for 10 minutes. Set to zero to disable. 
Invalid GPS Warning:  Sends an alert when the GPS signal has remained invalid for a 
certain time. Since version 4.88, the timer for this event only 
increments when the vehicle is moving. This prevents warnings 
where a vehicle is parked in a covered area. 
Data Format 
Send Full Heading:  Option to send full heading (accurate to one degree) instead of 
eight-point compass reading. Note: this option adds one byte to 
each position packet. 
Advanced GPS:  Modify the data included in each position report. This allows you 
to customize what data is sent to the server, and minimize 
packet size by sending only what is required. 
Encrypt Packets:  Turn encryption on. This option is only available for i50C 
firmware, and requires a DataGate-256 server. 
AES-256 Key:  Encryption key. This must be a 64-character hex string, 
containing digits 0-9 or letters A-F. 
Data Buffering 
Buffer Period:  If buffering is enabled, packets will be stored for this period, and 
then sent together. This option will increase efficiency for time-
based networks (Globalstar) and IP networks (cellular). 
Buffer Type:  Type of data to buffer. 0=GPS only. 1=GPS, Start/Stop, Idling, 
Status. 2=GPS, Start/Stop, Idling, Status, Waypoints, 
Overspeed, Input Change. Firmware versions < 4.71 used this 
setting (named Globalstar Buffer) for Globalstar networks only.
