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.

is the same diagram for the mb1000? i have to connect ca 50/200 to tzt3, and i got the mb1000 (which has a 10pin, and then and adaptor to a 12 pin for the tzt3)

mikidelnord,

The wiring for the MB-1000 differs slightly from the newer MB-1100. Here is the wiring connection diagram for the MB-1000:

many thanks! i will try

Hi, today I went to the boat and tested the connections. I can only see the low frequency, as shown in the photo (the transducer works because with the Furuno VX2 both frequencies were visible). It only appears if I select a 265LH-type transducer; if I choose, for example, 50/200, nothing shows up. So I’m not sure if I’m doing something wrong. I’m attaching a photo of the MB1000 connections to see if anything is incorrect.”

mikidelnord,

Re-check your wiring. It should be Blue & Green for the 200kHz side, and then Black & Red for the 50kHz side. Then go into the TZT2's menu and select the "50/200-1T" for the transducer.
