Dear Raymarine team!
We have an issue with ST70 and i70s instruments.
We use a Yacht Devices Humidity Sensor YDHS-01 to provide a Dew Point temperature data via
- PGN 130312 "Temperature" with "Temperature Source" = 09 ("Dew Point Temperature")
- PGN 130316 "Temperature, Extended Range" with with "Temperature Source" = 09 ("Dew Point Temperature").
YDHS-01 is also capable of transmitting temperature and humidity data in 130311 "Environmental Parameters" PGN.
However, both ST70 and i70s instruments show dew point value as "—".
From the i70s instrument "Installation & operation instructions" I can see that 130312 and 130316 PGNs are currently not supported by i70s instrument.
So I assume that the dew point temperature is a calculated value based on the humidity and temperature values given in 130310 and 130311 PGNs.
PGN 130310, on the other hand, is not supported by YDHS-01, so the only PGN which is available on both devices is 130311 "Environmental Parameters".
Unfortunately, I could not find the supported PGN list for ST70 instrument.
Q1:
Does ST70 support PGN 130311?
Q2:
Will the support of the 130312 and 130316 PGNs and the "Dew Point Temperature" Temperature Source be added in the future firmware updates for i70s?
Q3:
Is a dew point temperature calculated by the instrument? Is it based on the humidity and temperature values given in 130310 and 130311 PGNs?
Q4:
Is there is a possibility to setup ST70 and i70s instruments to use 130311 PGN temperature and humidity data to get a dew point displayed?
Q5:
We can change "Temperature Instance" and "Humidity Instance" data fields of 130311 PGN on YDHS-01 and set both as "Inside Temperature/Humidity" or "Outside Temperature/Humidity".
Does those setting affect a dew point indication? Which settings are correct?
Thank you, waiting for reply.
