Garmin 430W Interconnect to GPS 496

[luv2flypilot]

I was hoping someone has some experience connecting a Garmin 430W with a GPS 496. I have been told there is a way to connect the 430W to the GPS 496 in a way that you load your flight plan into the 430W and the GPS 496 will automatically show the same route without having to also enter a duplicate entry into the GPS 496.

My panel for my RV-7A consists of an AF-3400 EFIS, Garmin 430W, Garmin GPS 496, Trutrak DigiFlight II VSGV A/P, Vertical Power VP-200, Garmin SL-30, Garmin GTX-330 Transponder, and PS Engineering PMA900EX audio panel.

If anyone has some information on how to do this or if it is possible, it would be greatly appreciated.

I used information from a previous thread, http://www.vansairforce.com/communit...5&page=2&pp=10, to make the connection from my 430 to my 496 - works perfectly. I assume, but don't know for sure, the 430w connection will be the same as the 430. I had to get the proper pins for the 430 from a Garmin dealer.

Bryon,
I have a setup like yours and am very interested in a solution.

Jim,
I did a quick read of the full thread but could not find any thing about the 430 to 496. May be to early in the morning.
Sure would be nice to load the flight plan at home on the 496 and then pop it into the panel, push a couple buttons and go fly.

Here's what you need to do:

1. Connect an RS-232 OUT pin on the 430W to the 496's serial IN pin.
2. Change the corresponding RS-232 OUT format on the 430W to "Aviation".
3. Change the serial port format on the 496 to "Aviation In".

Note that this only works one way - i.e. you can't enter a flight plan on the 496 and have it appear on the 430W (no way could that ever get certified!).

Gary, the diagram on post #12 (http://www.vansairforce.com/communit...5&page=2&pp=10)actually shows a 195 instead of a 496 but both use the same yellow wire for data input. I used pin 56 (S1 output - aviation) on the 430 connected to the yellow data in wire on the 496. I also have a GTX 330 and as I recall I did not use the RS-232 output from the 430 since the GTX330 is communicating with the 430 via RS-232.

As an aside, for those with GTX 330 and GNS 430 it seems it is not possible to be set up both for the automatic flight plan transfer and to display traffic on the 496.

The "flight plan" transfer is a real time saver, especially to update a "direct to" next waypoint after an enroute deviation. Just hit the "Direct" button and then the execute button on the 430 and you'll immediately show direct from present position to the waypoint on both the 430 and the 496.

Hope this helps.

That's correct - but, you can still display traffic on the 430.

Matt, Right now I have the traffic from the 330 being displayed on the 496 and 430W. It sounds like if I connect the 430W to the 496 for crossfilling the flightplan, I cannot show the traffic on the 496 however I can still display it on the 430W. Is this correct?

The AFS EFIS moving map can also display the traffic from the GTX330 using the RS-232 format.

Does anyone know if I have to use pin 56 on the 430W to connect to the 496 data in? In looking at the wiring diagram of the 430W it seems to have multiple GPS RS 232 Outputs. Pin 56 is labeled as GPS RS 232 OUT 1, however pin 58 is labeled GPS RS 232 OUT 2, pin 41 is labeled RS 232 OUT 3, and pin 54 is labeled RS 232 OUT 4. I am wondering if all four GPS 232 outputs can be configured individually for format output within the unit set up, or possibly GPS 232 OUT 1 may be the only port able to configured for "aviation"?

Thanks,
