Navworx ADS600-EXP ADS-B Install

Anyone installing the Navworx in the RV-12? Would like to know how the install is progressing. The website indicates shipping was to begin on March 1.

Are you using a wi-fi link to an IPad for ADS-B In?

Since Apple put out iOS 8 my Wi-Fi links has been dropping out intermittently on the FreeFlight XVR978 unit I installed in my Cherokee and my 12. My iPhone 5S still runs iOS 7 and WingX works fine right along side of the IPad. I don't know if this is a problem for other receivers on WiFi, but my Dual 170 receiver works fine on Bluetooth with the IPad.

It really sucks when you spend the extra to get ADS-B In and have to use a portable receiver to get it!

I bought 2 of these but have not received them yet.

I too am in the group that will use a separate ads-b in receiver for the display.

Steve,

I don't know if iOS 8 caused problems for others, but I have let FreeFlight and WingX know about it.

I recently upgraded WingX and noticed that they recommended OS7, that OS 8 had issues.

<UPDATE> I've been asked to take some pix of our install and wiring changes. I'll try and document this work for others who have a GTX-327 transponder and D180 installation. I'll post pictures to this thread when I have them. </UPDATE>

I'm prepping a local RV-12 for an ADS600EXP we have ordered. We do not have the box yet, but we did ask for the install manual and to get the GPS antenna in advance. NavWorx has been very responsive to my many questions. So far there are only a few typos in the very complete install manual.

On the -12 we plan to mount the 1 lb 7"x5" box on TOP of the glove box. This is a one screen D180 -12. It was one of the first customer builds. The box has 3 antenna connections - two on the side (TNC female) with a DB-9 for the wires, and the UAT connector (sma female?) is on top in the middle of the box. I suspect this is to isolate the hi-power transmitter from the GPS and WiFi logic on the board.

I have yet to find any extra fused 12V outputs from the optional harness. The schematic says there should be two on pins 14 and 15 but I tried - they are inop. The schematic also calls for a "spare" switch that does not exist on this control panel. I plan to call/email Vans to see what they think about tapping power. The box must be independently fused.

Here is my wiring plan (some items still TBD):
ADS600EXP
DB-9
-----------
Pin 9: V+ (12v through 3A slow blow fuse or breaker)
Pin 5: Power GND
Pin 6: UAT Fail. Connect to D180 Contact input (p9 or p10 - one is for spar pin?)
Pin 7,8: GPSMAP 396 Data In (yellow) and Gnd (black). For Traffic.
Pin 1,2: GTX327 Pin 20,13. For Squawk.
Pin 3,4: GTX327 Pin 2 or 19 (from D180), 25 or 13 GND. For Alt-Enc.

After a few emails back and forth with Bill at NavWorx (thanks Bill) and some sussing out of the D180 RV-12 install, I've made some changes to the plan:

1) I discovered that the GPSx96 Serial in (yellow wire) is pinned into the Vans Control Board and it runs directly to the Transponder DB9 on Vans Control board (pin 5). This was probably to allow for traffic out of transponder to the GPS. I pinned that up and ran it past the transponder to the glovebox where I will mount the ADS600 to provide traffic from ADS600 to GPS 396.

2) Due to the limited access to switched power we determined we can use the GTX-327 switched power output (pin 14). It comes on when the transponder gets power.

3) The D180 contact pins are both taken (stall and spar pin) so I'm wiring a discrete LED to flash if UAT Fail asserts.

4) I grabbed the ground from the GTX327 as well so it turns out that the current wiring plan is mostly running that wire (#1 above) and adding a bundle out of the GTX327:

GTX (p14) -> +12v to ADS600
GTX (p13) -> GND to ADS600
GTX (p19) -> Altitude Encoder (ICARUS fmt) to ADS600. Requires splice.
GTX (p20) -> Squawk Code (REMOTE fmt) to ADS600.

Due to location limitations (978 Ant must be 5' from 1090 Ant and 2' from Comm) we have to run the UAT antenna all the way back behind the fuel tank.

When I installed my FreeFlight system I had to wire it to the GTX327 for an XPDR suppression signal. That turned out to be one of the worst goat ropes ever. I had to pull all my center stack components. I was a good Christian before I applied power and my prayers were answered --- now back to my sinful ways! 😈

Neil,
Thanks for the update. Is the length of the coaxial cable to the UAT antenna going to be a concern if the unit is mounted in the mapbox area and the antenna in the rear? Maximum cable loss per the manual is 2 db. RG-400 coaxial cable has a loss of 0.147 db/ft at 1000 MHz, which would limit the length to about 12 feet (allowing a bit of loss for the coaxial cable connectors).

Good tip on pulling power from pin 14 on the 327. I didn't know it was there, but Im wondering if it's too close the the 1.5 amp limit? Looks like it pulls 1.1 max.
Also, has anyone received one yet? They charged me for my order, but I was told it will be will into April before they ship.
Also, I notice they spec the antenna to use, and require a degree 90 SMA fitting on the UAT antenna to maintain warranty.
