"No Data Input" from Radar to Raymarine C80

[Northeaster]

Hi Folks,

I am getting a "no data input" message on the display after reconnnecting my 18" Radome.
I did splice all of the wires in the same manner as last year.
Although likely not the best splices, I used marrets for the power leads, and silicon telecom connectors for all ther leads, including the very small coax, which I just stripped back a bit and inserted the center into the connectors.

I would appreciate if someone can tell me the proper connector / procedure for splicing this small coax, but I would think that even with my splice, I would get some signal.

Checked the connector at the display, and the one in the radome, and look fine.

The small radar icon on the display does not have an x through it, but the softkeys to power it on / standby are greyed out.

Any thoughts?

Not Raymarine but Furuno - I got that message when the scanner stopped rotating due to the drive belt having slipped off. I suspect that anything that causes the scanner to stop rotating will also give the same message. Maybe the power to the scanner has been interrupted with your re-wire job.

I just did the same thing with my new radome the other day and luckily ...... because fitting those hair wires into the screw terminal is nuts..... mine worked OK. The only possible misstep I see (except of course not really making a good connection on one of those hairs) is that - did you also connect the shield of that little coax ? .... I did. Just guessing of course from here

Thanks for the replies thus far.

Andre - The marrets used to spice the power wires should be good, but I will check and redo them again.

Stan - I did also spice the shield wires on the coax, the same as last year.

May redo all of the splices, this coming weekend, and see if that helps.

Just was on a boat here in Hawaii with the same error message. The scanner had power, but would not rotate.

The Raymarine tech took both the display and the scanner off and shipped them off to be checked out. Three weeks later they were back, and checked out fine. The problem turned out to be a connection on the data wires--if memory serves me there are two wires described in the manual as data wires, and one is blue.

Thanks Don, I will check those data wires / splices this weekend.

Last weekend, I could not find one of my multi-meters, so I could not check the power or continuity of wires. I did remove the marrets on the power leads and got the same error. I do not think there is a problem with the power connections though, as the marrets were the proper size, and the wires were well twisted together.

I had a similar problem with a Furuno, it was a connection in the dome even though everything looked perfect.

Update. All fixed now. I had not looked closely enough at the splice box that I used, and had put the identical colored wires across from each other.
Never having used that type before, I did not see that each pair of wire was supposed to be reversed, and therefore had each pair of small wires backwards.

Thanks again for all of the help!
