Please Note: Updated Monday, May 26, 2020  We are open for business as usual. Well, mostly usual. We hold and ship inventory locally as well as directly from manufacturers and from some marine distributors. We are doing our best to reflect inventory that is actually available, but inventory updates are slower than usual due to the changing work situations for all business. Additionally, we now have started to see longer than normal backorders from manufacturers. We recommend that if you need a product not to wait until the last minute to order, as inventory may be gone for a substantial period of time once they go on backorder. International orders may also take longer than normal to ship.

Zinnos ZNC-910 Smart NMEA to Step & Log Converter (Modes 1, 2, 3)

ZNC-910 Smart NMEA to Step Gyro Converter converts from NMEA data (HDT) to Step gyrocompass signal.

This Smart NMEA to Step Gyro Converter is useful for interfacing between new Gyrocompass (such Satellite compass or without Step/Synch signal) and many navigation equipment needed for heading signal.








Mode-1: NMEA to Step-Gyro Converter (ZNC-910 Only) :

  • NMEA Input --HDT
  • Step Output 90/180/360:1 Stepper signal (+/-common)
  • NMEA Output HEHDT, 1Hz

Mode:2: NMEA to Log pulse Converter (with NMEA sentence Translation):

  • NMEA Input --VBW, --VHW, --RMC, --VTG (Automatically recognize) In case of VBW, ground speed has priority.
  • Log Pulse Outputs 4 Dry/Pulses 200/400/800:1 selectable.
  • NMEA Output VMVBW, VMVHW, GPRMC, GPVTG selectable. 1Hz

Mode-3: Log Pulse to NMEA converter (with Log pulse Repeater)

  • Pulse/Dry Input 200/400/800 pulse/knot dry or pulse signal.
  • NMEA Output VMVBW, VMVHW, GPRMC, GPVTG selectable. 1Hz.
  • Pulse Output 4 Dry/Pulses, or 3 Dry/Pulses + 1 Alarm output.
  • Alarm Output More than 8 or 10knots.

Common Specifications
