Upgrading ST40 to i50/i60 system

[Chuck - Raymarine - Moderator]

Steve,

R1a:In the years I have owned her, I have never noticed a junction block. Would it be required?
A1a: Negative. Networking the ST40 Instrument display to one another via the method described within the prior response would simply have been the means that data from these instruments would have been supplied to a larger system.
R1b: Could they have ran the depth transducer directly to the depth instrument and the same as the speed/temp setup too?
A1b: Yes. In all cases, these transducers would have had to have been directly connected to the transducer terminals of the ST40 Instruments.

R2: That was my original intent, until I saw the i70. My original plan was to use the i50 with existing transducers and the i60 for wind. As long as the ST 40 Transducers work with the i50s, then that may not be a bad idea either.
A2: Indeed the currently installed depth and speed/temp transducers may be either used with an i50 Tridata Instrument, with an i50 Depth and i50 Speed instrument, or with an iTC-5 with an i70/i70S MFID.

R3: Maybe I will just put an clinometer over the empty [censored].
A3. Should an EV-1 CCU be included within the system instead of a fluxgate compass, then it will not only provide the system with very accurate and very stable heading data, but also with heel angle data which in turn may be displayed by the i70/i70S MFID. Additionally, should it ever be desired to add an Evolution autopilot to the system, then it would not be necessary to purchase the EV-1 CCU along with the other Evolution autopilot components (as it would already be present within your system).
