SETTING DETAILS
Cellular This example uses the cellular network to transmit GPS locations to a
remote server.
GPS
GPS data is obtained from the GPS module (on appropriate model of
ZyWAN). This data is sent automatically to a remote network server
and is available via Terminal Server connection to the ZyWAN.
Networking Networking configuration allows access to GPS Terminal Server port.
The next sections provide detailed descriptions including the Web configuration pages for each setting.
Cellular Setup
The cellular page will depend on the model of ZyWAN and the network provider. The inbound TCP
connection to obtain GPS data requires the cellular account to have a static, public IP address.
GPS Setup
The GPS Terminal Server allows incoming TCP connections to be made to the ZyWAN to obtain raw NMEA
data from the GPS module. The desired NMEA messages may be enabled. This NMEA data may also be
sent to a local COM port.
The ActSoft or Arcom format UDP option allows the ZyWAN to send formatted GPS reports on a regular
basis to an external server.
