My flexible 8/16 ch Tx.

[kaos]

There is a 5V source at back plate , the bottom role left 1st.
that is where I get my neon tx on/off light power from.

As far as I know there is no 5V on that connector it's battery voltage.. If you have 5V in there then flysky made a very special 9x only for you
Also the frsky modules both have a 5V regulator inside. that is why the minimum operation voltage has to be HIGHER than 5V

If you want 5V, you have it on the big connector at the bottom, but not on the RF module pins..

That's what I said here

And Rick wanted to connect the DHT module and not a neon light

[kaos]

He will want a neon too.

Cracking setup you have there - this board really is the dogz dangly bitz - but finding that 4P4T slide switch in the UK (unless willing to pay DigiKey £12 to deliver an 80p switch) is shall we say 'problematical' heh heh! Anyone know of anywhere it can be found for sensible postage? TIA
Oh to be in the USA! Or China! lol!!!

[kaos]

have you tried Mouser to see what their shipping is? that is where I get them in the US.

I'm just looking at Maplin. Slide switches are only 2-pole, but there is a rotary 4-pole switch http://www.maplin.co.uk/rotary-switches-2417
or a toggle switch http://www.maplin.co.uk/4pdt-toggle-switch-2343

Tried Mouser but shipping to the UK is ... £12. Suspect Mouser and DK are the same entity as far as UK deliveries go.

Also tried Maplin here in the UK Mike, but theirs are only 4P3T so no good really.

A switch ... A switch! My Kingdom for a Switch! Lol!!!

OK, this finalized my SKY9X Tx. After the DHT is in, I thought I am done with it. Planning on using the DHT only for Frysky 2 way rx and left out the switches (1,2, fw). then I thought, why not fully utilize the function. so I add another 1P2T slider for me to use either 1/2 way rx. I do have one V series rx. the slider is also from Mouser: http://www.mouser.com/Search/ProductDet ... SLS121PC04
the size and the height of the slider is just right to place on the right side of the antenna, again, not like the stick switch, there is no chance to bump into it during fly and mess up. It is a SPDT switch but I leave out the fw wire, so in 2 way position , it is just not connected, while the other position will have the two wires shorted to be in 1 way mode. I left out the fw reflash function out because I figure I have to open the tx to do it any way for connection of flash wires. with a 2 position switch just for 1/2 way, no chance to flip to fw mode by accident.

Now this tx is closed 'for good'. NO reason to do anything more on it. except to replace backup battery or flash the DHT fw if needed.

Any idea if this work on the 9XR radio also

Per

[kaos]

no, only with Sky9x board. It has 2 ppm out put. May be the future XR pro board will have, don't know the detail.
with 9X or 9XR you can only have 8ch with trainer function or 16 ch without trainer function using the 4P4T switch. also the telemetry source can only be from one module while Sky9x board has two com port for telemetry selection.

[MikeB]

If you want 16 channels on a stock 9X, consider the XJT module. In PXX, D16 mode, it supports 16 channels to two X8R receivers.

Mike.

[backman8571]

I can get 12 channels to work

I use the XJT and 8 servos plus 2 sbus module's for 8 more servos but it only recognice upto ch12 not sure why

I have done the telemetry mode's and they work fine with my DHT module.

So in theory you should get all 16 not sure why 12 only works for me and the sbus module's show all to comunicate

Per

[backman8571]

Mike

I am using the XJT with the 9XR and i can get 12 channels, not sure why not 16 with one X8R receiver and 2 sbus conerter's they are programmed to ch 9-12 and 13-16

When i pug them into my Taranis they work fine but not from the 9XR

I made a simple mix where i set the gear switch to +100 and -100 in the oposit position

I use that for ch 9-16 just for testing

The result is on the rasio monitor they do show as moving but the servos only move on ch 9-12

But on the Taranis all servos move from ch 9-16

Per, you won't get more help by posting on every single thread in the forum.

It will only get confusing for you and for the people trying to help you.. please keep your questions only in one place.

I think most Sky9x board users have been replacing the RTC backup battery by opening up the Tx.
I have a 6 pin PS2 connector built for recharging the main battery so I don't need to open up the battery door and I have not opened my battery door for almost a yr that works great. Until lately my RTC backup battery ran out on my. I 'have to' open up the Tx to replace it. Every one knows the T9X Tx box screw and its hole is darn weak, just a few times of screwing and unscrewing it may be no good.
Yesterday while I opened up my Tx 'again' to replace the backup battery. Something dawned on me. How stupid I was, there is no need to put the back up battery holder inside the Tx and have to fix it with double sided tape or glue. Just run a pair of wires from the SKY9X V. B1 backup batter header through the side slot of the battery compartment and keep the RTC backup battery in the main battery compartment. No need to open up the Tx to replace RTC battery any more.
I run a 2S 2650 mah Tx battery which leaves ample room for the button battery holder in there. And I think the HK 1500 3S LiFe also have ample room for the RTC battery holder to go in.
I think this works pretty good, will force me to check the main battery pack every time I need to replace the RTC battery, about 9~12 months.
Just to share this with any one has a SkY9X V B1 board and a T9X box. If you put the USB in that slot, just drill a hole for 2 wires to run through and use a servo connector to the board.

Oops! I think I made a mistake on installing the two way switch for 1 way/2way mode on the DHT. I was trying to bind a V-Rx found out it won't bind. It dawned on me I may have the one way/ two way wires mixed up. My understanding the 2 way position of the original 3way switch should be not connected while 1way or FW update should have two wires shorted. I may have the wires mixed up.
Can any one confirm in this pic which wires should be shorted for 1way rx? green+black or yellow+ black? I am using only a two way switch for 1/2way without the FWupdate position. I assume all I need is just use the other wire but like to get a confirmation before I opened up the Tx , AGAIN.

edit: problem solved, yep just swap to the other wire and it is fine. 50% chance, and you always pick the wrong one.
