[DG] [DG11] autopilot oscillates back and forth

[Derek - Raymarine - Moderator]

Hi Kmac
Thank you for your enquiry.

To carry out the software update to the EV pilot and equipment connected to STng backbone it would be best to temporarily ONLY connect the master EClassic display to the STng network. The suggestion would be to make this connection temporary, disconnect the SeaTalk from this display also, ( to prevent a data loop ) and to leave the SeaTalk part of the system powered down.

Carry out the Software update via this temporary connection and confirm the EV pilot , p70, ACU and converter are all now updated.

Then reconnect your network as previously, connect the master E Classic back to Seatalk, leave the STng adapter cable plugged in to the Master E Classic, ( for future software updates), but disconnect it from STng to prevent a data loop.

Check you system now operates all correctly as it should.

With the software update complete, the autopilot can then be recalibrated, this FAQ found here will help identify potential reasons the pilot drive oscillates, check the PILOT CAL LOCK is OFF when you do your calibration, since this will give you access to features like RUDDER DAMPING which can be increased to stop the oscillation.
