IP Setup > GPS Configuration
An rCell unit with a –GP build option enables the GPS Configuration. The –GP option allows you to configure forwarding of
NMEA (National Marine Electronics Association) sentences from the built in GPS receiver to a device connected to the serial
port or over the network to a remote host. The TCP Server, TCP/UDP Client and Serial Port Dump can be enabled
simultaneously. All enabled sentences will be forwarded periodically using the interval specified in the NMEA Configuration
section. Before forwarding, the rCell prepends an ID Prefix and ID to each enabled NMEA sentence. The NMEA sentences
available are those provided by the built in receiver which are: GPGGA, GPGSA, GPGSV, GPGLL, GPRMC, GPVTG. Detailed
descriptions of the supported NMEA sentences are provided in the Universal IP AT Commands Reference Guide provided on
your product CD.
Local Configuration
The Local Configuration allows you to configure the TCP server port and allows for a serial port dump.
TCP Server Enable/disable TCP Server. The default is Disable.
Port Sets the port on which the server is listening. The default is 5445. The port range is from 1 to 5 digits,
each digit between 0 and 9 inclusive. Note that numbers above 65,535 are illegal as the port
identification fields are 16 bits long in the TCP header.
Password If a password is supplied, the TCP server will request that the remote client supply a password before
sending the NMEA sentences.
Serial Port Dump Enable/disable the Serial Port. The default is Disable. The serial port configuration settings will be
used to configure the port. The serial port client/server must be disabled in order to use the serial port
for GPS.
Remote Configuration
The Remote Configuration allows the device to connect to a remote server using the IP and port information for uploading GPS
data.
TCP/UDP Client Enable/disable the TCP/UDP Client and defines the protocol of the client. The defaults are Disable
and TCP.
Remote Host Displays the IP address and port number of the Remote Host.
Password If the Remote Host requests a password, the password entered here will be sent to the server in
response.
NMEA Configuration
The NMEA Configuration allows you to configure the time interval, any additional prefix or ID information and forward NMEA
sentences.
Interval The Interval is defined in seconds. The default is 10 seconds. The interval range is from one to 255
seconds.
Add ID Prefix The ID Prefix is 0 to 10 character prefix prepended to the ID.
Add ID The ID is an unique remote asset identification string. The ID string can be any length up to 20
characters, except that the & and $ are invalid characters. The ID must follow the standard NMEA
sentence structure. Refer to the Universal IP AT Commands Reference Guide provided on your
product CD for sentence structure.
