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.
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, VTG) to the Log Pulse contact closure signal. It can be used especially for old radar, autopilot, gyrocompass, ODME system.
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.
