[CA] [CA11] Trouble displaying boat speed from Signet sensor

[HKrausz]

Here is the update regarding connecting Signet sensors to iTC-5. Good news is that the depth now shows correctly on the i70s display. There are 3 or 4 temperature leads from that sensor (Temp +, Temp -, ground, and "cutoff") and using temp - and ground leads to the temperature posts in the iTC-5 gives an incorrect temperature reading. I'll try other combinations next to see if I get a correct reading.

Nevertheless, by connecting temperature leads, the separate boat speed sensor now displays. Bad news is that it displays 0.0 all the time. I checked with Signet and am attaching the spec sheet. It puts out A/C voltage and frequency proportional to speed. Please let me know if you think this should be compatible. If not, perhaps there is a compatible speed transducer available somewhere that is 1 5/8" in diameter, not 2". I did confirm that the iTC-5 is working by hooking up the Airmar DST800 that came with my bundle and spinning the paddlewheel.

Thanks again for your help.
