MultiModem rCell User Guide  

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 are forwarded periodically using the interval specified in the NMEA Configuration group. 
Before forwarding, the rCell inserts an ID Prefix and ID to each enabled NMEA sentence.  

Available NMEA sentences are: GPGGA, GPGSA, GPGSV, GPGLL, GPRMC, GPVTG.  

For detailed descriptions of the supported NMEA sentences, see the Universal IP AT Commands Reference Guide. 
You can download this guide from the Multi-Tech website.  

 

The Local Configuration group allows you to configure the TCP server port and allows for a serial port dump. 

 Enable or disable TCP Server. The default is Disable.

 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. 

 

If a password is supplied, the TCP server requests that the remote client supply a password 

before sending the NMEA sentences. 

Enable or disable the Serial Port. The default is Disable. The serial port configuration settings 
are used to configure the port. The serial port client/server must be disabled in order to use 
the serial port for GPS.
