GPS configuration
The GPS tab looks like this:
GPS (global positioning system) data is gathered from the GPS receiver using the
standard NMEA protocol and may be redirected to either a serial or TCP port. See the
NMEA Web site (www.nmea.org) for more information on the NMEA protocol standard.
The GPS data may also be cached and delivered to a server in another format using
the UDP protocol.
The following options may be configured to enable the collection and distribution of
GPS data:
Option Explanation
Forward GPS to
physical COM Port?
Select Yes for this item to send GPS data to a physical
serial port on the ZyWAN in NMEA format. See page 73.
Enable GPS Terminal
Server?
Select Yes to enable a terminal server on the ZyWAN,
which allows a host to connect and obtain streaming GPS
data over a network connection in NMEA format. See page
75.
GPS UDP Message
Format?
Select a data format to enable the ZyWAN to send GPS
data over a network connection using UDP protocol.
Available options are None, Arcom Format, and ActSoft
Format. When selecting the ActSoft Format, the server
