How it works
Garmin PND is installed in each vehicle, along with iTegno 3932 modem. The PND is connected to iTegno 3932
modem via a serial port, and the iTegno modem acts as a gateway to transmit wirelessly the Garmin PVT data
to the monitoring control centre. Please refer to Garmin Device Interface Specification.

Settings for Moving Map (real time tracking)
Once the Garmin PND with iTegno modem is powered up, the modem will initiate TCP Client Application using
iCOMM Manager Stack.
It will establish a GPRS connection, connect to the predefined TCP server
automatically and send a message “GPS device connected” together with modem IMEI and SIM Card number
to the defined server. After the server received the message, the following settings need to be configured and
enable PVT data at the Garmin device.
o
Enable Fleet Management
o
Request Product ID and support request
o
Request unit ID/ESN
o
Turn on PVT data
After the setting is done, the modem will be accessing Garmin GPS data and filter the PVT and satellite data
package. It will drop the satellite package and filter the PVT package according to the user setting. If the
condition matches, then the PVT package will send back to the backend server. Otherwise, the package will be
dropped. When server received a PVT data, it must send “ACK” back to the modem. Otherwise, the modem will
resend that data after timeout.
Based on the PVT data received, the user is ready to plot and provide a real time tracking on a map application.
