Mike, Before you go ahead with this I have a question - what is the thickness of the wing skin & inspection plate in the area you may want to install the pitot tube ?

BTW - I had a similar issue & rigged up an (on)-OFF-(on) biased switch (vans Flap switch ) wired the same way for direct trim motor ops instead. I used a 15 pin dsub connector into the AP Panel harness & just used the same power/ground/trim motor wiring. This will give you manual trim control...

You need to contact support directly with the serial # of the AP Panel.

does anything fly without airspeed ?😂😂😂

Did you contact VPX ?

No need to bother with 'bussing' the Cat 5, it has a different function & is not part of the network wiring. I'd suggest 1 of 3 potential problem areas considering you have wrung out the wiring using a multimeter. 1. One of 9pin dsub connectors is not properly seated. 2. A socket in a dsub has...

This should do it --SETUP MENU > LOCAL DISPLAY SETUP > BATTERY BACKUP (SV-BAT-320) STATUS, then on that page BATTERY CONNECTED (BATTERY DETECTED): YES / NO - tell it NO, don't forget to 'SAVE' ;) HDX install manual rev AD 15.3 page 9-5.

There is I think 4 different RS 232 ports in the 430 W, have a look in the GNS menu - you won't get 2 ports allowing you to use the same type of data, however if you need MapMx for 1 then you could ? use Aviation or aviation no alt for the other ? There are some notes in the G5 manual under...

Geoff - send me a pm with your number & we can discuss the issue. Jake

First thing I'd do is download & read the install manual if you haven't done so already - come back here if you are still not sure.

You can split the RS 232 out to both units.

Try pages 2-4 to 2-5 of the Install Manual RevAD v15.3 .

Ah, the joys of 'remote' troubleshooting. EGT/CHT 'spiking' are a known issue for some earlier EMS units fixed initially by using filtered dsub connectors & then by a hardware fix. RPM - is there a 30KoHm resistor added to each p-lead to EMS rpm input - assuming it has mags only ? Map - is there...

same applies to the trim hat switch - I use a small toggle switch on the pilots side panel for disabling co-pilots side stick.

5amp c/b is suitable - current draws for all devices are in the install manuals. :)

Most likely a misunderstanding- a network is a network is a network, we’re talking about 2 x pairs of wired here (4 in total). As you most likely are aware the servo power & grounds are 20 gauge & the power has to have an independent circuit breaker system from the network cable, the only other...

Tom - send a picture of your panel as I have a simple cost effective method to prevent future damage, depending on your panel layout of course.

No pics at this stage, customer is slow with build progress & I won’t be needed back interstate to the install until after Xmas.

I nearly always splice both servos into 1 x dsub connector to a hub, reduces the need for a second hub. you could try another port on the hub too.
