Local Delivery
5.8.3
The GPS data can be delivered to up to two local PCs with UDP viewer programs can provide data
through a TCP connection, e.g. telnet. GPS data will be delivered once per second to all local PCs
TCP Server Format: Select one of the following options for the format of the GPS messages
TAIP no ID: Trimble ASCII Interface Protocol, a Trimble specified digital
communication interface. When this option is selected, the TAIP vehicle ID is not
included in the GPS messages.
TAIP with ID: Same as above except the Vehicle ID is reported
NMEA National Marine Electronics Association interface specification for electronic
equipment. The NMEA GPS message set includes several message types, each
containing specific GPS information. See message descriptions below. TAIP Vehicle ID
is not reported when NMEA is selected.
NMEA GLL: Position in LAT/LONG coordinates and time of day in UTC coordinates.
NMEA GGA: Position in LAT/LONG coordinates, time of day in UTC coordinates, fix
quality, number of satellites and altitude
NMEA RMC: Position in LAT/LONG coordinates, time of day in UTC coordinates,
ground speed in knots, heading in degrees and date
NMEA VTG: Ground speed in kilometers per hour and knots, heading in degrees.
To get GPS data by telneting into the device, enter the following from a prompt
telnet <local IP address of the Sentry4G> 6257.
Note:
It is possible to telnet to the Sentry 4G unit's port 6257 from a remote location however
this is not recommended as delivering the data once per second across the broadband
802.16-2005 network will greatly increase the amount of data transferred.
UDP Host Format: Same options as TCP server format
UDP Host Address: IP address of local PC that GPS data will be delivered to. This address
must be on the same subnet as the Sentry 4G LAN IP
UDP Host Port: Port assigned to UDP program. This must match the port assigned in the
chosen UDP Port Listener Program.
Remote Delivery
5.8.4
The GPS data can be delivered to up to three remote PCs with UDP viewer programs running on the
host.
Report every: GPS can be programmed to report position after a specified time has elapsed
or the unit has moved a specified distance since its last report.
But no less than:
if its "Report every ..... meters" setting is sufficiently low" by setting a minimum amount of
time, in seconds, between GPS reports.
001-9193-001 Version 1
This feature prevents a fast moving vehicle from reporting too frequently
