Garmin 430W RS-232 Error

[BigTex]

Guys - On a flight today I started receiving the following message " Not receiving 232 input data on channel #2" on my Garmin 430W.  Any thoughts on what might be causing this error/message?

Is there anything connect d to your 430? JPI, stormscope? It means that it is not receiving information that it is supposed to receive form one external box.

I have a STec 50 with GPSS and a GTX330ES connected to my 430 but both appear to be working.

Pull the individual breakers on the stec and gtx while everything is on and see if an error message pops up for each. You should get one each time a connected unit is powered down.

Try contact cleaner.

And that doesn't work look at the wiring diagram and trace the pin. Make sure it's seated not damaged. Once it goes into the connector and harness it may be darn near impossible to trace. You may be able to rule in out which device is not providing data. How is altitude sent to your GPS?

Go into the Setup and check what RS232 port #2 is configured 

it may be fuel flow or TIS-a traffic or altitude encoding ....

Sometimes the boot up on the 430 and the boot up on whatever device is connected don't sync. Just restart both and it'll probably go away.

Looking at the configuration screen, it looks like it might be the fuel transducer might be acting up.

Config setup is incorrect...ch 2 should be input =shadin fuel output  =aviation ...Adsb out should be on another ch altogether say ch 3 or 4....may need to be rewired for max function

Interesting. This has been wired this way for several years and this error just now started occurring every so often. I'll take it to my avionics shop to see what they say.

Thanks for the guidance

You hAve a shadin miniflow or fuel flow?

[thinwing]

I mean since you have to 3 empty ports (channels)I think it would work better splitting the two devices also what make model Adsb transponder?

I have a GTX330ES. I'll need to check what fuel flow is installed. It was in the plane prior to my purchase.

Oh boy...so you have no input at all from the gtx330es?

Its configured using the 429 interface.

Sure is!Ok than its just the Shadin..my config is 2 way

reminds me of a previous thread on avionics intalls . 

I do believe that avionics install have become easier from a hardware standpoint ( what used to require several wire now just requires 1 or 2 via an RS 232 or ARINC 429) 

however, settings have become more subtle

Yeah but you still have to run the wires and the pins can be really hard to get to

Had this come up the other day on a flight, but it was because we didn't have the fuel flow turned on, so as others have said...make sure all the units connected to the 430w are receiving proper power!

I won't disagree.  That's why a good crimping tool is a must have

And you would not believe how many pounds of wire I removed from the plane when un-installing and ADF and a remote DME.

Most avionics shops just leave the old wires there and terminate them.

That's really crude work leaving old wires...no I ment the back side of Garmin trays where the pins insert have those damned aluminum guards the prevent easy access to pin blocks after initial install

You would be surprised how many shops do not want to remove old wires.

On connectors, I know what you mean. The current connectors are very cramped, especially since many wire require shielding.

The worse I have seen are probably audio panels'. GMA 340 or PS8000 where almost all pins are used.

I wish those manufacturers did build an extension for the connectors

What an engineering concept...intelligent design using connectors available easily after initial install..where access is challenged

The cleanest install on a PS Engineering Audio Panel is to have them make the harness.
