I would like to control my Powermax via the RaspberryPi, with a web gui.
Eventually I want to control the Powermax via an android app.
I found some hardware in my box and tried to connect my Pi via an USB-serial converter to the Powermax connector.
my usb-serial device has an old prolific chip which is not supported under windows8.
So I can't try the software package that comes with the Powermax to program the alarm system.
Now I'm stuck in receiving and sending the right data from the Pi to the Powermax.
I hope someone can help me to get this connection up&running
------------------------------
Some other data so far
------------------------------
The serial adapter is connected as follow:
PI - Powermax
GND - GND
RX - TX
TX - RX
Powermax pin's found @ domoticaforum.eu/viewtopic.php?f=68& ... 152#p53758
------------------------------------
|?0V GND TX RX 3.75V |
|?0V ?3V ?0V GND 3.75V |

When I connect the tx and rx on the serial adapter together I get my own echo/reply's when I'm pressing some keys.
