VTX Runcam Split 2 Issue

And can someone verify the pinout on spektrum satellites? Is it the same as on lemon rx?

What one does ivan have?

I'm very sure it's this one. He mentioned it in an above post but didn't refer to a model no.

Spektrum Quad Race Serial Receiver w/telemetry (SPM4649T): Spektrum - The Leader in Spread Spectrum Technology

Yes, that is the correct pinout. I don't like positive on the outside, but is what it is.

 

[bigone5500]

I must not have something setup right. This spektrum sat is not binding either. This is on a DYS F4 FC.

 

[Tony]

Did you turn on the UART port in the config tab?

 

[bigone5500]

UART3 right?

 

[Tony]

It will depend on what port you put the signal wire in.

 

[bigone5500]

I'm going to take the top off and take a photo of the board. Give me a few.

 

[bigone5500]

I have it connected to RX1.

 

[Tony]

Then it will be uart 1 I think. Been a minute. And make sure you are powering it from the 3.3 rail and not the 5v rail.

 

[bigone5500]

I moved the wire from RX1 to RX3 and set uart to 3 in BF. The sat still doesn't bind. I get a short blip of the led in the sat when I power it.

 

[Tony]

Is the satellite dsm2 or dsmx? And what code are you trying to use to bind it?

 

[bigone5500]

It's DSMX and I'm using set spektrum_sat_bind = 9. Then save and it reboots. I think the sat should flash when it is in bind mode. I checked the power and I am getting 3.2v.

 

[Tony]

try 3, 5 and 7 and see if it changes anything.

 

[bigone5500]

No changes.

 

[Tony]

screen shot your config and receiver pages

If these uarts behave the same way a USB COM port in Windows does... then the number in Windows may be assigned dynamically when they are plugged in. If so... then when you plug in, you'll hear a notification sound and the device should show up in device manager and tell you what port number that was assigned to it.

If they don't behave the same... then just ignore this post

 

[bigone5500]

Actually the usb in windows is working. I can connect the FC. It's the satellite Rx that will not bind through the CLI command.

In Configuration, change the satellite to SPEKTRUM1024. And show me the ports page.
