NMEA talker / listener

NemaTalker simulates the output of up to 6 different instruments simultaneously: GPS, Weather, Sounder, Heading, Velocity and Radar, plus a feature to create your own custom formatted sentences. All output is sent to one dedicated serial port. Input from this port can be logged in an optional log file. The dynamic parameters of each instrument can be controlled via a common set of controls: the "cockpit".

Serial communications over RS232C

The program will transmit proper NMEA 0183 sentences via a PC serial communications port using the industry standard RS232 interfacing option. This data then can be processed by chart plotters and other devices without the need to leave the workshop or office. Instead of hardware serial ports third party virtual serial ports can be used as well.

TCP/UDP transport

NemaTalker can optionally send the NMEA data over the TCP User Datagram Protocol (UDP) to any UDP client.

Talker *and* Listener

Although the name of the program suggests that it can act as a "talker" only, it is also capable to receive incoming data, so functioning as "listener". Incoming data however is not processed, but the raw NMEA data can be stored in an optional log file and made visible in a convenient trace window, showing incoming and outgoing messages simultaneously.

Simulates up to 7 instruments simultaneously

The program can simulate the output of 1 to 7 different instruments simultaneously: GPS, Weather, Sounder, Heading, Velocity and Radar, plus a virtual device to generate custom formatted proprietary sentences.

The Cockpit

Dynamic parameters that are common to all instruments (altitude, course and velocity) are collected in one panel at the right side of the window, called "the cockpit". Common parameters that are more static of nature can be set and altered in a separate window. Large buttons are provided to "open" any of the 7 instruments. They can also be opened in the "Instruments" section of the main menu.

Other features

The speed can be set to either knots (Nautical miles per hour) or kilometers per hour. 

Most of the settings and the "current state" are saved upon exiting, so when restarting the program you can continue where you stopped.

The GPS instrument is equipped with 2 very exciting options. One option is the automatic running according to a waypoint file, where the program "follows" the waypoints of that file. You can not alter the course manually.

The second option is the "navigate" function. The program runs also according a preset waypoint file, but you can alter course and speed, and you will see a simulation of the cross-track error (XTE) on the instrument.

NemaTalker supports both NMEA version 2.20 and 2.30/3.01.
