Introduction to PinPoint-E EDGE/GPRS
data on another computer system, or other client functions (such as data only being sent out or only
being received after an initial request).
Common Uses for the PinPoint-E
If you need to contact your PinPoint-E, a device connected to the modem, or a host system using
the modem from the Internet, you need to have a known IP (such as one which is static) or domain
name (an IP address which is converted by a DNS server into a word based name). If you have a
dynamic IP address for your modem, you can use a Dynamic DNS service (such as IP Manager,
page 15) to translate your IP address into to a domain name.
Caution: If you want to connect remotely to your PinPoint-E using TCP/IP, the IP
address given to your modem by the network cannot be a private or internal IP
address (such as a) unless you are on the same network or inside that network’s
firewall (such as with frame relay).
Using Your PinPoint-E to Connect to the Internet
In Public Mode, your PinPoint-E will pass the IP address from Your Wireless Service Provider’s
network to your device or computer. In Private Mode, your modem will assign configured, static
local network IP addresses for the modem and your device.
The modem will perform a one-to-one routing for all internet traffic to and from the computer or
other end device.
If you need to have more than one device connected to the Internet through the modem, you will
need to have a router connected to the modem. The modem would provide the one-to-one con-
nection to the router with the router configured to provide a broader NAT service to the other
devices connected to it.
You can connect directly through your PinPoint-E to the Internet using the Ethernet port or use
PPPoE for a password protected connection. For a direct connection, the PinPoint-E features
DHCP (enabled by default) so you don’t need to worry about setting up an IP address on your
computer. DHCP works with both Private and Public Modes.
The PinPoint-E’s rugged construction and cellular connection make it ideal for use in remote and/
or industrial locations.
Because of its GPS capabilities, the PinPoint-E is ideal for vehicle tracking and other situations
where mapping a moving object is as important as connecting to a network.
