8.5.2 Configure GPS Operation (CTM120 only)
The operation of the internal GPS feature may be configured from the Chameleon Controller
Software application.
From the Tools menu select GPS Configuration:
The GPS position information may be
sent to a remote location over the wireless
connection and over the local serial
connection to the host computer. Each of
these connections may be independently
configured. Data is sent as a $GPGLL
NMEA 0183 sentence.
The local GPS reporting may be enabled
either for this session only or for this and
all future sessions. The GPS update rate
may be set to a value from once per
second, to once per 3600 seconds. GPS
data is sent as a UDP packet to port 5005
of the local host PC. The Chameleon
Controller Software application provides
an automatic utility which makes this data
available on a virtual COM port in the
computer which may be accessed by
standard mapping software applications.
When the remote connection is enabled it must have a remote IP address and port number
configured. This will be the remote server that will accept this GPS data and allow tracking of
the vehicle or equipment in which the modem is installed. The GPS update rate may be set to a
value from once per second, to once per 3600 seconds.
