Powermax plus pinout

Hi,
I have a powermax plus alarm panel and I want to use the ’ Visonic Alarm Panel for Home Assistant’ integration.
I bought the USR-WIFI232-D2 moduke but I’m having a hard time to find the correct pinout (gnd, tx, rx and power)
I have a 14 pins layout and haven’t seen the same layout…
Has someone managed to find out the correct wiring?
Thanks,
Ron
