Global Positioning System (GPS)

Rev 2.0 C Aug.10 195

a. Set *PPIP and *PPPORT to the IP address and port of the server to

which you want the reports sent.

b. Set the GPS Report Type (*PPGPSR) to your preferred NMEA sentence

format.

•E0 - NMEA GGA and VTG sentences.

•E1 - NMEA GGA, RMC, and VTG sentences.

Local Host

Local reports are sent to the local IP address of the computer or device

connected to the serial port or USB port of the AirLink device using PPP. To

configure the modem to send to the local IP, you will need to set 3 commands:

*S53, *PPLATS, and *PPLATSR.

a. Set the port (S53) to the local port to which you want the reports sent.

The local IP address will automatically be used. S53, in ACEmanager, is

part of the GPS group.

b. Set the Local Report Type, *PPLATSR, to your preferred NMEA sentence

format.

•E0 - NMEA GGA and VTG sentences.

•E1 - NMEA GGA, RMC, and VTG sentences.

c. Set Local Reporting Time Interval, using *PPLATS, to the number of

seconds you want as an interval between reports being sent.

Streaming Messages (Local)

The AirLink device can be configured to send standard NMEA messages

(sentences) in ASCII over the serial port and/or USB port without a PPP

connection to the local computer.

Send the command ATGPS1 to the serial port, ATGPS2 to the USB port, or

AT G PS 3 for both to begin the NMEA stream. The example below shows the

stream in HyperTerminal connecting directly to a AirLink device via the comport

and/or USB port. To stop the stream, with either terminal connection, use the

command ATGPS0 (this can be entered even while data is streaming).
