Re: cheap(er) p1-to-USB cable for smart meter (looking for a ...)

Hi,

I got a ISKRA AM550 meter a little while ago and I bought a Serial converter with a FTDI chip embedded into the pcb, however I am not seeing any data. The manufacturer of the cable has put a 10k resistor between RXD and RTS.

Should I move the Resistor to be between RXD and +5v?

Kind regards ...
