CA50-200-12M Connectivity

[AlMog82]

Hello gentlemen,

I have a boat that has a CA50-200-12M (i think) connected via a 5-pin cable to an old FCV-522 and I'd like to replace this sounder with a more modern unit. Options are FCV-588, GP1971F or one of the TZTouch2/TZTouch3 units. My question is: Can I splice the 10-pin pigtail (AIR 033-333) to the CA50-200-12M's cable or do I need to add an MB1100 matching box to connect to those units?

I'm sure the question has been asked before but i couldn't find any definite answers using the search function.

Almog82,

The CA50/200-12M is one of my favorite Non-Diplexed Transducers, and you'll need to utilize it with a MB-1100 Matching Box if you want to connect this transducer to any Diplexed Fish finders like the FCV-588, GP1971F or any TZTouch2/TZTouch3 MFDs.

Thanks for the quick reply, Deep Blue. Now, does that also apply to the FCV-295 (as in, does it also need a matching box for the CA50/200)? And, is the diplexing thing related to the Rezboost, Accufish and Bottom Discrimination functions on these newer sounders?

AlMog82,

Diplexed Transducers use a single transmission line for both the High and Low frequency elements, and then alternate their transmissions.

Non-Diplexed Transducers has separate High Frequency and Low Frequency lines and this requires the use of four wires going to the separate transducer elements. You could connect a Diplexed Transducer to the FCV-295, but only one channel would work.

Rezboost, ACCU-Fish, and Bottom Discrimination rely on specific transducers capable of handling both the Low- and High-Frequency echo returns. These features work in conjunction with proprietary algorithms within specific Furuno Fish finders to interpret this echo return data. The CA50/200-12M is one such transducer that is compatible with all three functions. But you'll have to use an MB-1100 Matching Box if you plan on using the CA50/200-12M with a Diplexed Fish finder.

I hope this information is helpful..?

Very helpful and much appreciated. Does the FCV-295 also need a matching box to connect to the CA50/200?

No, the FCV295 is a non-diplexed unit. It uses non-diplexed transducers like the CA50/200.
