Several actions per event:
Have the unit initiate a time counter, set an user signal true and reset a distance counter
whenever the vehicle's ignition goes high:
>SED35SV0;F00+;ACT=SGC05TC;ACT=SSSU041;ACT=SGC07U<
Checking the host software/server
At this point and as long as the unit remains GPRS attached, an EV message should be
arriving to the AVL server every 5 minutes. The software must be able to interpret
the EV messages generated by the unit. If you run into troubles checking your AVL
application you can always shut it down an use some popular free TCP listener applications
that will show you the RAW data received, and confirm that the reports from Syrus are
being received properly by the server. Another useful tool is a network sniffer that allows
you to analyze the traffic on a given TCP/UDP connection while the the AVL server is
running.
