I am trying to change the node id on the 5th emonTH I have just got. The other 4 have been configured using DIP switches, so I’m now using an FTDI serial adaptor to do this. I already had an adaptor I use to reconfigure stepper motor drivers for my 3D printer:
The pinout order of this board’s header is:
DTR, RX, TX, VCC (set to 5v), CTS, GND.
From what I can see from the EmonTH schematic that is the same:
I am using Putty on Windows 7. Baud 115200, 8n1, no flow (also tried xon/xoff). I know my FTDI board works as I have tried a wire link between TX & RX and keystrokes echo in the terminal. When I connect the FTDI board to the emonTH I can see the prompt asking me to press +++ then Enter, but doing this does nothing (shift and “=” key on keyboard, or the + key next to the numpad and either enter key) and after 5 seconds it times out and shows me the data it is broadcasting.
I have tried the same programming lead on another emonTH and I am still unable to +++ enter to get into the node config.
All my emonTH’s are v2.0.2. Any suggestions please?
