You say "TX wire directly connected to COM1-RX/TX".
Where, exactly, do you mean by "COM1-RX/TX"?

Orange module TX pin connected to the COM1 port left pin (labelled as RXD/TXD pin) and module GND to COM1 port right pin (GND) with simple dupon jumper wires
I made a small open space on module front cover to get access to the DTR/TX/RX/Vcc/GND pins externally and also connected a pair of wires into the 9XR COM1 port, that comes out thru a hole.

That RXD/TXD signal also connects directly to pin 5 (bottom pin) of the module connector (used by FrSky XJT module for SPort telemetry).
Check whether your module has anything that connects to this connection.

Thanks, it's been solved by modifying Orx module internals (wire TX to RF) instead of connecting module TX to COM1. Dont know why but it's ok now :)
Also figured out while testing with DJT setup that the COM2-Futaba outlet has reversed pinout (RX vs. TX) after changing it DJT also works fine

The COM2 connections may not be reversed, it is normal to need to connect the Tx signal from the module to the Rx connection on COM2.

Hi Mike,

When setting up the spare analog and spare Digital inputs how do I assign them to a source or switch?
What is their label? I can't find "spare-Dig" or "Spare-ANG" in the available choices.
I'm attempting to use the spare analog as a 3-way switch and the spare digital as a single through switch.

Much thanks

You will have to enable it in the hardware menu. To find out how to enable the hardware menu please press menu long and then scroll down to "Help"

Does anyone have a schematic of the main board, I found one at another forum but the link provided was not working anymore, I'm trying to find if any of the test points are for the USB connection, my computer isn't reacting in any way when I connect the USB cable, even though the radio does change from the firmware selection to the Connecting screen.

Check the cable works with another device so you are certain it is not a "Charge only" cable.

Everything obvious has been checked.

There are no test points on the USB data signals. They are available on pins 12 and 13 of J9. Take care not to short to pin 14 of J9 as this is the ERASE signal.

Since you see "Connecting" then the 5V from the USB is being detected by the radio.

Took the connector board off, checked the connections all the way to the main controller, everything seemed ok, put everything back again and now it works, not sure if the board wasn't making perfect contact or something but it works fine now.

For future reference, R46 and R48 are connected to D+ D-, the resistors are 100Ω.
