4.2 NMEA data message
DISCO-B4-GLONASS delivers data in the NMEA-0183 format. Table below lists the NMEA and
FALCOM output messages supported by the DISCO-B4-GLONASS device and gives a brief
description for each protocol. For further description about these protocols, refer to the related
documents [1].
The running firmware inside the device offers the possibility to switch on and off each protocol
that is listed in the table below. As mentioned above the firmware inside the device supports a lot
of PFAL commands enabling full control of the device. There are also PFAL commands which allow
sending of these protocols via SMS, TCP, Data call and e-mail. For example, the PFAL commands
"
PFAL,GSM.SMS.Send...
" and "
PFAL,TCP.Client.Send...
" allow you to send an SMS message to a
user or a TCP packet to a TCP server to let him know the current location, GPS state, UTC time,
Date, Speed and Course over ground of the device. The received SMS contents or TCP packet can
be forwarded to a map software for locating the device graphically on it. When you install such a
device in a vehicle, you are able to have always full control of the vehicle. In this way you will know
where your vehicle is, what is happening with your vehicle, has your vehicle been moved without
authorization from a park area, real time vehicle movements and more. The TCP server developed
by FALCOM called "
Trace4You
" has a lot of such features allowing you to have full control of your
vehicle, fleet and other assets.
