ID 0/1/2 switch

afon · Post by **afon** » Tue Nov 10, 2015 2:51 pm

Hi All

I have a question about ID0/1/2 switch.

When I turn on my radio with switch in the middle (or low) position I can see "Check your switches warning" with ID0 highlighted there.

But when I am trying to test switches at "diagnostics" page (setup section of radio menu) I can see only ID1 and ID2 indicators there.

Both modes (ID1, ID2) can pass tests only if I turn on (position "down") "Aileron switch": ID1 on in the middle position, ID2 on in the lower position.

With "Aileron switch" turned off (position "up") I have some unclear results for all 3 positions of "ID switch"

Is it normal?

Best,
Dmitry

Doesn't sound right. On the DiagSwitch menu, if there is a 0 beside ID1 and ID2, then the switch is at ID0.
You might have a wiring error, please do the following:
Ther are 6 combinations of the AIL switch and ID0/1/2. For each of these, please report the values (0 or 1) beside ID1, ID2 and AIL on the DiagSwitch menu.

Mike.

Hi Mike!

Here are all combinations of AIL and ID switches.
Also I took video for you: https://www.youtube.com/watch?v=FMq8IaGWkLY

I'm wondering if the wiring to the two switches is wrong. Has the radio alwayes been like this?
Could you take a picture of the wiring to the two switches? They share a common 0V (ground) connection. If this is in the wrong place on one of the switches it could cause the problem.

Mike.

Hi Mike!

radio is completely new, it was delivered from HK 2 days ago and was never opened or modified by me.
I will take pictures (of two switches and connector) and post them here.

Is it OK that ID0 is absent at DiagSwitch menu?

Best,
Dmitry

Post by **MikeB** » Wed Nov 11, 2015 10:30 am

Yes, it is OK ID0 is missing. If ID1 and ID2 are both 0, then ID0 is active!
A small change I need to do is make this display as ID^, ID- and IDv as a single entry.

Mike.

It will be nice if you do this mod for all switches that can be converted to 3 position switch.

Post by **MikeB** » Wed Nov 11, 2015 7:14 pm

Converted switches already do display in this format, it is just the IDx switch, which has always been a 3-position switch, that displays as ID1 and ID2.

Mike.

Hi Mike!

Here are 2 photos of connector and switches. I guess GEAR and ID wires were mixed (according to this diagram: 9XR Pro Wiring)

Best,
Dmitry

Post by **MikeB** » Wed Nov 11, 2015 11:21 pm

As far as I can see the switches are wired OK.
On the connector to the main board, the black wire is ground. Please set the ID switch to ID1 (middle) and the AIL switch UP. Now measure the voltage between the black wire and each of the Orange, Grey and Blue wires. You should see about 3.3V.
Switch the ID switch up (ID0), and repeat the measurements, then switch ID down (ID2) and repeat. Finally, put the ID switch back to the middle and switch the AIL switch down and repeat the measurements.
These will check the switches and their connections.

Mike.

As far as I can see at least two wires go to wrong switches: one for ID and another one for GEAR.
I am not sure about TRN and AIL wires because at this moment I have only pictures (I am in office right now and my radio at home).

Can you please confirm that this 9XR Pro Wiring schema is correct?

Best,
Dmitry

Post by **jhsa** » Thu Nov 12, 2015 9:47 am

It seems also to me that the green and grey wires are swapped. The blue should be correct on AIL?

You can try swapping them and see if it fixes the problem.

I was comparing your pictures to a 9XR-PRO of mine. Your wiring looks to match mine, and both differ from the colours shown on the link.

If you could do the voltage measurements I described this would be useful.

Mike.

But the colors of his 10 pin connector match the diagram.. The switches do not.. That means that Brent made a mistake on the diagram then?

Thanks. These are not as expected.
With the AIL switch down, please do the measurements with the ID switch in all three positions.

Mike.

I swap those two wires and got MORE strange result that was definitely not correct.

At least without swapping my GEAR switch shows correct values in DiagSwitch menu.
With swapping GEAR does not switch correctly.

Aha, I wonder if the diagram is correct then.. Or I don't understand anything

I wouldn't be surprised

I think the diagram is wrong.

I have a strong feeling that something wrong with ID switch.
Do you feel the same?

Unfortunately I do not have right now spare switch to check my idea.

Seems to me like blue and grey are linked together?

AIL up
ID Up: yes
ID middle: no
ID down: no

Ail Down
ID Up: no
ID middle: no
ID down: no

Connection was tested by digital multimeter in "Diode test and connectivity check" mode.

Post by **MikeB** » Thu Nov 12, 2015 8:48 pm

Definitely something relating to the signals on the blue and grey wires.
Maybe you could try the following.

Unplug the connector and remove the blue, grey and orange wires from the housing. This may be done by gently bending the retaining tab up then pull the wire and crimp contact out.
Now plug the connector back in.
Power the radio on.
You should see ID1 ON.
Now connect each of the three pins where the blue, grey and orange wires were, in turn to ground.
One should remove the ID1 highlight.
Another should turn AIL ON.
The third should change from ID1 to ID2.

This test it to decide if the fault is in the wiring/switches, or on the PCB.

You might either need someone else looking at the display, orset up in front of a mirror so you can easily see the display while making the connections.

Mike.

Hi Mike

I did all tests with radio on/off during adding new wires.

3 Out
ID1:1, ID2:0

+blue
AIL Up: AIL:0, ID1:0, ID:0
AIL Down: AIL:1, ID1:1, ID2:0

+gray
GEAR Up/Down - OK, other are always 0

+orange
Problem as it was described before.

Best,
Dmitry

OK, please look at the processor. The IDL2 signal and AIL signal are on adjacent pins (67 and 68). Look closely at these pins and see if there is a solder short between them.

Mike.

afon · Post by **afon** » Thu Nov 12, 2015 10:19 pm

As far as I can see with my magnifying glass the is no bridge between 67-68.
But I did not check other side of PCB.

Dmitry

Post by **MikeB** » Thu Nov 12, 2015 10:30 pm

It could be there is a short somewhere else on the board. It is also possible there is a short internal to the processor.
It is worth using a fine needle and gently scraping the point between pins 67 and 68 of the processor to make sure there is no high resistance short between them, possibly under the chip itself.

If the short is somewhere else, you would need to follow one of the tracks from the processor, looking closely (with plenty of magnification) for any possible shorts.
