Configuring the PinPoint-E for GPS
To configure your modem’s GPS settings, you can use either Wireless Ace or a terminal connection
to configure the modem using AT commands (page 62). The configuration examples in this chapter
all use Wireless Ace. Most of the settings are in the group: PinPoint.
Before you Begin to Configure GPS
To decide what configuration you need for your PinPoint-E, there are some fundamental consider-
ations:
1. Protocol: What is the GPS protocol used by your tracking application and what type of reports
will you need?
2. Datum: What is the datum supported by your tracking application?
3. DNS: Will you need DNS support?
The main sections below detail how to set up the configuration for RAP (page 42), RAP special
features (page 44), RAP Store and Forward (page 46), NMEA (page 48), and TAIP (page 50).
Most of the PinPoint-E commands are covered in the main sections below.
Configuring the Datum
You can change the Datum used by your PinPoint-E by configuring *PPGPSDATUM. Match the
Datum to the Datum used by your tracking appliction.
Over-The-Air (Remote) Host
To set the PinPoint-E to report to an external or remote host, configure *PPIP (ATS Server IP) and
*PPPORT (Server Port). *PPIP will work with any remote host.
You can use a fully qualified domain name instead of an IP address for most con-
figuration options calling for an IP address if your PinPoint-E is configured to use
DNS. DNS settings frequently come directly from Your Wireless Service Provider
while your PinPoint-E is registering on the cellular network and receiving it’s IP
address.
Caution: With the PinPoint-E, all local GPS (UDP encapsulated) reports will come
over the Ethernet connection. Raw GPS data can be transmitted across the serial
port for applications which require COM traffic.
Note: Some PinPoint-E models do not support configuring the Datum with Wire-
less Ace. If the option does not appear in Wireless Ace when you connect to the
PinPoint-E, then your modem does not support it.
