About the GPS module on TransPort routers
One of the options available on some models is the ability to connect a GPS receiver which
enables the router access to geographical position information. The GPS module may be internal
or external. In either situation, an internal asynchronous serial (ASY) port is used for the
connection. The standard way that GPS modules send the data is using National Marine
Electronics Association (NMEA) standard 0183 messages. This protocol is usually simply referred
to as NMEA. Routers offering this functionality support the most common NMEA data messages.
These messages are described below. GPS receiver modules normally accept configuration
commands which specify which of the NMEA messages should be sent to the requesting host.
