Seatalk2 to STng

[Chuck - Raymarine - Moderator]

Kevin,

Unfortunately, support for ST290 is limited and ST-STng Converter testing did not include an ST290 instrument system. Accordingly, should the ST-STng Converter have been updated with the latest available Raymarine product software update and should the behavior(s) persist, then the reported behaviors would be deemed a feature of integrating the ST290s with current equipment. Should the vessel's ST290 system not include a ST290 Graphic Display, then the suggestion to replace the function of the DPU with an i70S MFID, connect the pods to the SeaTalkng backbone, and then connect the ST290 displays to SeaTalk port of the ST-STng Converter has merit. Otherwise, the best that you can do is to ensure that all ST290 and STng equipment has been updated with the latest available software ... should this not correct the behavior, then would be recommended that the customer consider replacing the ST290 system's DPU and any ST290 displays which did not have a basic SeaTalk communications interface.

Q1) The ST290 remote (connected to ST1 network) beeps but there is no control of the ST290 instruments.
A1) I assume that you are referring to the ST290 Autopilot Remote. See the comment above concerning SeaTalk to SeaTalkng Converter software, as early ST-STng Converter software did not support integration with autopilot systems. I have verified that Auto, Track, and Standby modes may initiated by a ST290 Autopilot Remote which has been interfaced to a SeaTalk bus which has been connected to a SeaTalk to SeaTalkng Converter (i.e. NO DPU in the system). If updated with the latest software, then please specify the make/model of autopilot course computer which has been installed within the system.

Q2) Waypoint Arrival: WP arrival pops up on the MFD and on the ST290 instruments when you hit the arrival radius. Hitting the OK on the MFD silences that but does not silence the alarm at the instruments. Since the remote isn't working at the helm you have to silence it at the instruments (companionway or nav station).
I was only able to silence the alarms on the instruments FROM the master MFD a couple times after updating ST1-STng converter to v2.03 (hit or miss, and only on the master). Once I brought the MFDs from v17.46 to v19.03 I couldn't do it again.
A2) Which specific instruments are sounding an alarm? Does the system feature ST290 graphic displays or other non-analog ST290 displays?

Q3) The COG appears to be different (and wrong) from what the MFDs show. The customer states that it remains correct on the autopilot remote but I haven't verified that.
A3) What specific model of autopilot remote are you referring to?

Q4) The ST290 mentions the Waypoint Arrival Alarm in the manual however there is NO option under the Alarms chapter to even turn this off. Tried it in both Sailing and Full profile but couldn't turn up this alarm option.
A4) Arrival alarms could not be disabled in this generation of Raymarine equipment.

Q5) It seems like the ST290 system is getting the appropriate waypoint data, arrival, range, bearing etc, but it doesn't seem to get the acceptance command from the MFD or anything from the remote. Would the ST1-STng be blocking data in that direction?
A5) If the autopilot, ST-STng Converter, and DPU are each not operating with the latest available software, then this is indeed possible.
