Hello

I am totally confused. I try to download from an URC7140r02. I have got an usb to TTL FT232RL without cables shown up in Windows 10 with newest Driver.

Questions:
* How to tell RemoteMaster Device Upgrade Editor, v2.10 build 3 which port to use? (I've got more than one serial)
* How to find out about the JP1.x Version for this remote?
* How to cable this jp1.x to adapter? (RTS is available, GND is available, but use TX / RX or TXD / RXD)?
* Batteries in or out of the Remote?

Thank you, bye, Andreas

* Look at the COM port assigned in Device Manager in Windows or choose "Automatic" in RMIR, NOT in "Device Upgrade Editor". That's the wrong program.

* JP1.3 or 1.4

* Common pinouts: https://hifi-remote.com/forums/viewtopic ... 589#p108589

* Batteries in
