Roberto,

Please view my post titled "Connection issue with Head Unit and Comm Cable" from about 9-10 months ago. I tried different cables - same issue. The joystick sticks even without the cover in place.

Roberto, After returning my unit due to a head unit connection issue - and buying a new controller board - I am having similar problems. Now my daylights do not come on. In troubleshooting, I see that by jiggling the cable connecting the head unit, the lights do flicker and I can position it so that...

No, not screwed too tight. I removed front cover and worked joystick around without cover. It sticks continuously in the UP position only, and yes I can pull it down to stop it. Can I remove the joystick and reseat it? - or shouldn't I even try?

Otherwise, things work just fine.

Tim

Roberto,

I just connected the head unit with the new board that you installed. The scroll button sticks and menus continue to scroll. For example, I go to change the date and time and it just keeps scrolling fast. This never happened.

What can I do?

Tim

New cable, same results. I am assuming that the board's connection is the issue. Your thoughts?

Is this a standard cable?

Roberto, Today, I noticed that my first relay box was not working. As I looked into this, I unplugged and disconnected the head unit. As I plugged things back in, the lights flickered but stayed off. As i worked with it, there is definitely an issue between the head unit and the communication cable....

This worked. Thanks!

Any thoughts?

Roberto, I am starting over and have attempted to start from scratch. I have created a simple sketch for my RA which works. Now trying to reinstall my wifi attachment following the manual. The wifi attachment does flash blue and green. When I open the wifi utility and try to connect, this is what I ...

35.0 - 35.2. Perfect

I just allowed the 35 solution to float in tank for a while. I didn't realize that temp had such an impact.

Thank you Roberto!

I brought the 35 solution to tank temp. Now I'm getting 35.8, 36.0, ...

Much closer. I will work on it.

Thanks!

That makes sense. I will do that, as well as bring my 35 solution to tank temp.

I am also having a friend double check a sample of my tank water for salinity.

During calibration, the numbers fluctuate around 2930. After calibration the probe (still in 35 solution) reads 357 - 361. Much closer. Placed in tank water it reads 390. From this, I would assume my water is too high. So, I check with a hydrometer and calibrated refractometer. Both read 35 dead on....

Roberto,

I have tried several times. I recalibrated and still get high readings. You can see in my charts that the salinity reads around 38-41. Could I be missing something in my code? My probe is not fully submersed? Should it be?

Tim

Roberto, I've installed the replacement probe and get high readings. Each time I attempt to calibrate I get similar results. When calibrating, as the probe sits in 35 solution, the numbers fluctuate around 2768, not in the 3000s, like before. After calibrating, my tank reads 421 on the controller. M...

No, nothing I can see.

It does have a rust-like spot on the wire, similar to the original one. Would a picture help?

When calibrating, it fluctuates from 250-350, not the 3000+ you'd expect.

The probe clearly has fluid inside. It is 3/4 full or more.

The water in the bnc connection appears to have come from inside the cable, if that's possible. The outside of the cable and connector seem dry.

Roberto, My replacement probe seemed to work for a while. Then I started getting odd readings - all wrong. I have checked all cables and disconnected and reinstalled, also recalibrated several times. It never recalibrated properly, as you described earlier in the thread. When I disconnected cables, ...

Roberto, Received package today. Installed it and calibrated in 35 solution. It read 3320. This sounds like the correct range, from what you have said before. I knew my salinity was high and it read about what I expected. As I lowered my tank's salinity, probe seems to read as expected. It looks lik...

At the tip of the probe itself, one of the wires connecting the small plate within the glass, seems to have some significant rust. Is there a way to send you a picture?

Then I try to recalibrate and while calibrating
35.0ppt solution reads 0, no fluctuation
Tap water reads 0, no fluctuation
Tank fluctuates around 570 +/- 10

Does this make any sense?

When I upload code does it add to what i have, or replace all existing code? Sorry for such a basic question.

Where do I place this code? I'm still pretty new to this.

Is that what you would suggest?

Took everything apart and checked programming, cables. Still no reading. When I enter calibration, the red "0" never fluctuates.

I will take it apart tomorrow and check again. Thanks.

Checked all cables, recalibrated, same results.

And with the decimal adjustment it reads 6 ppt
