Real-Time Clock Sync
Every hour, the PinPoint will sync the internal Real Time Clock (RTC) with the 
Coordinated Universal Time (UTC) received from the GPS satellites. 
Applications, such as ATS and the Event Browser, will then translate the time 
reported by the PinPoint as part of the GPS message to the appropriate local time 
zone using the UTC offset (i.e. California is UTC-8 and New York is UTC-5).
Note: 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 Cali-
fornia 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.
Configuring the PinPoint for GPS
To configure your modem’s GPS settings, you can use either Wireless ACE 
(page 11), direct serial communication or Telnet (page 73) to configure the modem 
using AT commands (page 76). The configuration examples in this chapter all use 
Wireless ACE.  Most of the settings are in the menu option: PinPoint.
The main sections below detail how to set up the configuration for RAP (page 40), 
RAP special features (page 43), RAP Store and Forward (page 46), NME
(page 49), and TAIP (page 54).  Most of the PinPoint commands are covered in the main sections below.
Over-The-Air (Remote) Host
To set the PinPoint to report to an external or remote host, configure *PPIP (ATS 
Server IP) and  *PPPORT (Server Port).  *PPIP will work an NMEA or TAIP 
remote host as well as with an ATS remote host.
