AirLink PinPoint EDGE/GPRS Manuel D’Utilisation

acknowledged.  The PinPoint will continue until the server acknowledges receipt.  When the Pin-
Point receives the acknowledgement, it will advance its “window” to the next group.  

When the PinPoint is first powered on (or reset), it will send a Set Window message to sync up 
with the server for the current “window”.

On the other side, if the server receives an out of sequence packet, it will send a message to the 
modem noting the missing sequence and the PinPoint will retransmit.

GPS Time, Latitude, and Longitude can be added, *UDPRGPS, to the packet sequence data for 
Reliable Mode.

You can configure the PinPoint to send reports based on a time interval  and on the movement of a 
vehicle (based on it’s position from one time to the next).

*PPTIME - Location report sent every set time interval (seconds).

*PPDIST - Location report sent only if the position is more than the set distance (x 100 meters)

*PPTSV - Location report sent if the vehicle has been in one location (stationary) for more than 
a set time interval (minutes).

*PPMINTIME - Location report sent at no less than this time interval (seconds).

If you have events enabled, with *PPFLUSHONEVT, you can configure the PinPoint to flush the 
SnF buffer when an event occurs.  This will immediately send all pending SnF messages to the 
host.  This allows an event, such as a vehicle being powered on or a tow bar activated, to be imme-
diately sent, so its cause can be acted on without delay.  

Using SnF Reliable Mode can cause excessive data traffic if the sequence 

number is not returned.
