Reading a Kamstrup 382 JxC on P1.
First install the FTDI driver.
Find the lastest drivers here:
http://www.ftdichip.com/FTDrivers.htmWith
5 Volt cables from FTDI (TTL-232R-
5V-WE)
3-wires from FTDI-cable: Red=Request, Black=GND, Yellow=Data=RXD
RJ11-port on the kWh-meter: pin2=Red=Request=+5Volt, pin3=black, pin5=Yellow=Data
You can test with a terminal emulator on your PC.
Terminal settings: 9k6, 7databits, Even par, stop=1, No handshaking, Line mode, CR+LF
Invert the RxD in the driver from the FT232R-chip.
Used the FT_PROG Utility, do NOT forget to Cycle port after programming .
