[CA] [CA11] adding I70s to existing network for transducer compensations

[Ron Kohn]

I currently have a network consisting of an A95 mfd, ST602 autohelm connected to an SPX5, an I60 wind, and am using a ITC-5 for the depth and speed transducer connections. I want to add an I70s to the network so that I can do compensations on the depth and speed as the A95 will not allow this. The 5 way connector is full and I want to know if it would be better to daisy chain the new instrument off the I60, or add a "T" into the network to handle the I70s. OR---RR is there some other way to do compensations on the depth and apeed ?

Welcome to the Raymarine Forum Ron,

The only devices which are capable of calibrating instrument transducers which have been interfaced to an iTC-5, setting offsets setting alarms associated with such transducers, and setting alarms associated with such transducers are the i70S, i70, and ST70 MFIDs. Should the i60 Wind be interfaced as a spur to the SeaTalkng backbone and the total length of the two SeaTalkng Spur Cables which would be required to interface the i60 Wind and daisy chained i70S MFID to the backbone does not exceed 6m, then it would indeed be acceptable to daisy chain the i70S MFID to the i60 Wind instrument. That said, it is considered to be a best installation practice that devices supporting SeaTalkng / NMEA 2000 communications be installed as individual spurs to the system's powered and properly terminated SeaTalkng / NMEA 2000 backbone. Accordingly, a T-Piece or 5-Way connector would be recommended for adding the i70S MFID to the system.
