AirLink PinPoint EDGE/GPRS Manuel D’Utilisation

In addition to different reporting protocols, the PinPoint supports the most widely used GPS datum.  
The GPS datum is the method of ascertaining the position of the GPS device using a specific refer-
ence point location.  The datum used can influence the accuracy of the GPS positioning.

Real-Time Clock Sync 

Every hour, the PinPoint will sync the internal Real Time Clock (RTC) with the Universal Time 
Coordinated (UTC) received from the GPS satellites. 

Many tracking applications will translate the time reported by the PinPoint as part of the GPS mes-
sage to the appropriate local time zone using the UTC offset (i.e. California is UTC-8 and New 
York is UTC-5). 

TCP GPS Polling 

The PinPoint can easily and quickly be polled for location by opening a TCP connection to port 
9494 (default). Once the connection is established, the PinPoint will send a report with the current 
position using the GPS report type the modem is configured to use.

You can change the port for the TCP GPS poll using *TCP.

Wireless Ace displays the current time (UTC) set in the modem and does not 

translate it to the local time zone.  If the modem is in California and it is 8 a.m., the 
modem’s time will be shown as 4 p.m, since UTC is 8 hours “ahead” of Pacific 
time (UTC+8).

As a security measure, the TCP connection to the *PPTCPPOLL port must 

be from the IP address specified for the ATS Server IP in *PPIP.
