This section describes the details of the serial port commands through which the TISTAR25 is 
controlled and monitored. The serial port commands allow users to set the receiver 
parameters, configure output message type, and retrieve status information. The baud rate 
and protocol of the host COM port must match the baud rate and protocol of the GPS receiver 
serial port for commands and data to be successfully transmitted and received. The default 
receiver protocol is 4800baud, 8 data bits, 1 stop bit, and none parity. 
 
 

The TISTAR25 supports NMEA-0183 output format as defined by the National Marine 
Electronics Association (

http://www.nmea.org)

. The currently supported NMEA messages for 

GPS applications are: 
 
 

Global Positioning System Fix Data 

 

Geographic Position – Latitude / Longitude 

 

GNSS DOP and Active Satellites 

 

GNSS Satellites in View 

 

Recommended Minimum Specific GNSS Data 

 

Course Over Ground and Ground Speed 

The optional NMEA checksum can be enabled or disabled when setting up the NMEA protocol. 
The checksum consists of a “*” and two hexadecimal digits derived by exclusive-OR of all the 
characters between, but not including, the “$” and “*” characters.
