ETR-30N Transducer Settings

[fishinengineer]

I just installed a VX2 with a ETR-30n sounder module. This replaced an FCV-292 sounder. My transducer is a bronze flush mounted 50hz/200hz unit (no speed or temperature) that was attached to the FCV-292. There is no label to be found anywhere on the the transducer or cable. The 292 worked great but it was time for change.

Upon opening the FCV-292 this is what I found:
switch S1 1(on) 2(off) 3(off) 4(on)
JP10 set at A
JP11 set at A
Board 02P6208 A50kh indicating "C" 200khz indicating "C"

Is there any way to determine the tap settings or any other required adjustments from the FCV-292 information. I manually set the frequencies at 50kz and 200kz in the VX2, without any other adjustments. Is there a way to identify the transducer through measurement? Transducer is at least 12yrs old.

When you don't know the model of the transducer, you are always safest to use Tap "A" and Tap "A".

Thank you Johnny, I will follow this advise.

Fishenengineer,
What color of wires does the transducer have?
Are they Green, Blue, Black and Red?
If they are, the transducer you have is a CA50/200-12M.

Thanks Snips, I'll check next time I get to the boat, I was thinking this may have been the case. Transducer wires come through a terminal strip where they're split off to the two connectors for the Etr=30n. Thanks
