[CA] [CA11] A127 Needing Transducer Options

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Dave,

Q1) Is it possible to interconnect the Seatalk and SeatalkNG networks so that the depth will display on the A127?
A1) ST60 instruments may be adapted for use with an a-Series MFD. An E22158 SeaTalk to SeaTalkng Adapter would be used for this purpose. The a-Series MFD would then be able to repeat numerical data from the ST60 instruments. However, the a-Series MFDs fishfinder features cannot be supported by an instrument depth transducer. Should fishfinder features be desired on the a-Series MFD, then it would need to be interfaced to a compatible fishfinder transducer.

Q2) If replacing say the old speed sensor, what Transducer would be recommended? I would hope to 'pop' out the old speed sensor, (thru hull looks to be 2" in diameter with low slope of the hull less than 15 degrees).
A2) If the old speed transducer is operational, then there should be no need to replace it. If replacing an instrument speed/temp transducer, then an E25025 ST800 / P120 (Plastic) Speed/Temp Transducer or M78716 ST800 / P120 (Bronze) Speed/Temp Transducer would be recommended.

Q3) The existing speed sensor is a 'waterwheet' type, and I am happy to just get speed from the GPS sensor.
A3) Then you need simply configure the MFD's Databar, Data application cell, or Databox to display the SOG (Speed Over Ground) data item.
