Hello everyone I am looking for help with the NX8E security system. I am unable to connect to the NX8E serial port even with the P0003 serial cable. I need to know the settings on the keypad needed to get the serial port to send information through the serial port to a Putty Session. Any help would be appreciated. I tried the DL900 software but even that software fails to connect to my NX8E security system.
