NSLC-21 NMEA to Speed Log Pulse Converter
The NMEA to Speed Pulse Converter interface converts, incoming speed data as NMEA to log pulse speed format.
An NMEA log pulse converter is a device used in marine applications to convert data from one format to another, typically from a pulse-based log (speed sensor) to an NMEA 0183 data format.
On some older marine bridge navigation devices, speed data was accepted based on a contact closure signal. NSLC-21 converts the NMEA speed data format (VBW, VHW, RMC, VTG) to the Log Pulse contact closure signal. It can be used especially for old autopilots, gyrocompass, ODME systems.
The NSLC-21 can be powered within the range of 9~32 VDC. The nominal voltage of 24 VDC is advised for powering the device in normal operation. Power input port has a protection for incorrect polarity connection of the supplying voltage.
In summary, an NMEA log pulse converter is an essential device for integrating traditional pulse-based log sensors with modern marine electronics, ensuring seamless data communication and enhancing navigation accuracy.
