Ac Infinity probe cable lengthening and splitting experiment

My goal for this experminent was to lengthen the probe on the Ac Infinity cloudline fans. I have a T8 and A T6. Both are short about 4 foot of what I need. I also wanted to split the signal so that I only had to have one probe sending data split to two control units. Those of you that run two T model fans may find that one will read 73RH while the other reads 72RH for example even though they are right next to each other. I wanted to eliminate this.

I read reviews where people were not successful in lengthening the probe cable. I found that the probe cable used a 4 pole/conductor TRRS type meaning it has 3 bands/ insulators on jack. I found this cable
https://www.amazon.com/gp/product/B00S1R7F2U/ref=ppx_yo_dt_b_asin_title_o00_s00?tag=ilovegrowingm-20 and it has the proper pinouts and works to extend the probe fine.

I tried using this https://www.amazon.com/gp/product/B01I37CIEW/ref=ppx_yo_dt_b_asin_title_o05_s01?ie=UTF8&psc=1 Y spliter to split the signal. It did not work. Only one jack can be plugged in at a time or both control modules lose signal.
I also tried this https://www.amazon.com/gp/product/B07D7W16Z1/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 splitter hoping it might work. It does not. Same as the first. One line plugged in data goes to the control module. two lines plugged in neither module receives a readable signal…

So thats where I am at on this deal right now. It would be nice to only have one temp/Rh reading to deal with but not sure what the workaround is as of yet.

I wondering if splitting is causing line voltage to drop and the sensor is just that sensitive.

That’s who id call

@dbrn32 is the master so his input. Anything electrical I would trust him with. No ifs, ands or buts. :+1:

I’m not exactly sure what they are using, but sounds like that’s your issue. It’s going to use a resistance base to then change to analog signal. I don’t see any way to make that work off the top of my head.

Well it was either you knew or didn’t. :+1:

thanks for the input. much appreciated.

Wonder if there’s some sort of signal boosting splitter. One that doubles the signal and splits it to two outputs.

Or I wonder if something like this would work. You wouldn’t be able to use A and B output at the same time but maybe the volume knob would act as a gain and boost the signal and then you could add the splitter.

I think a signal multiplier would do it. Would need to make sure you get something compatible with temp sensors. Ac infinity may share that information.
