[CA] [CA11] Lighthouse 19 compatibility with S2G course computer

[Chris - Raymarine - Moderator]

Hi Tony,

Q1) The wind calibration would be one through one of the four I70 displays right? If yes, does it matter which one and/or I assume it only needs to be done on one of the displays?
A1-You can perform the wind calibration from any of the i70 displays.

Q2) What exactly is the difference between the "calibrate" and "align" operations? If I am confident in the wind speed results but not direction do I only need to align?
A2-Align is usually associated with direction. Calibrate is usually associated with speed. These terms can be interchangeable depending on the context.

Q3) Due to an unrelated matter (it appears my stored cordless drill slipped into a position too close the compass and and was throwing off the reading), I also want to use my P70 control to swing and GPS correct the fluxgate compass which is connected via the course computer. Seeing I will be going in circles anyway for the wind instrument, can I calibrate both at the same time and/or if no, does it matter which calibration I do first?
A3-You can perform the wind and pilot calibration at the same time.

Q4) At some point hopefully relatively soon I hope to replace the fluxgate and S2G with the newer EV1 and ACU-200. I noticed my S2G does not require the RF connection but the ACU-200 does. I believe I have access to the copper grounding/bonding wire system for the boat in the general area of where the S2G/ACU-200 will be mounted. Just want to be sure I don't have to worry about introducing any stray DC current via the ACU-200 into the bonding system and introduce a new possible source of electrolytic corrosion?
A4-you can view the ACU-200 has a newer version of the S2G. If the S2G did not need it then you will be fine with the swap.

Chris,
