ST60 Depth Display

[[email protected]]

I have a defective ST60 Depth Display,
connected to C90 Widescreen MFD.
I need to replace ST60 with new ST60+, or i70 Depth or i70 Tridata Display.
Currently using AirMar tranducer.
What new parts do I need to make this conversion?
Will my current thru-hull AirMar transducer work in the up-grade?

Welcome to the Raymarine Forum Jim,

If only seeking depth data, then it would be recommended that the ST60 Depth Instrument be replaced with an i60 Depth Instrument and a D244 SeaTalk Junction Block. To do so, the depth transducer's leads would simply be disconnected from the ST60 Depth Instrument and then the transducer's leads would be connected to the corresponding color coded terminals of the i60 Depth Instrument. The SeaTalk cable connected to the ST60 Depth Instrument would be unplugged from the ST60 Instrument and plugged into the D244 SeaTalk Junction Block. The SeaTalk to SeaTalkng Cable supplied with the i60 Depth Instrument would then be used to connect the i60 Depth Instrument's SeaTalkng port to the SeaTalk Junction Block.
