X941-E 35/70 – Stepper Interface

REF: INT-0009

SKU: INT-0009

X941-E 35/70 Stepper Interface

 NMEA 0183 input to Negative DC stepper voltage output

The X941-E 35/70 will accept either NMEA data or DC stepper voltage and convert the signal into 35V or 70V negative DC stepper.

  • Input 1- 6 steps per degree, 5 to 50v (+ve or -ve common)
  • Input 2 – NMEA 0183 heading data
  • Output – 6 step per degree, -ve step signal (+ve common, -ve stepper)
  • Output voltage selectable between 35 or 70V
  • Suitable to drive up to 6x free-running analogue repeaters

Other X941 Stepper Interfaces available

The X941 series interface converts serial heading data into traditional gyro stepper transmission, and also acts as a stepper amplifier.

An X941 series allows a new heading sensor such as a modern gyro, magnetic compass, or satellite heading sensor to connect to existing bridge repeaters or existing radars and navigational aids.

The X941 series can be used in both retrofit and new installations.


A vessel replaced one of its gyros which only had NMEA as an output, to avoid the cost of replacing the original motorised step repeaters an X941 was used at a fraction of the replacement cost of new repeaters.
