Hi, Are there any tutorials or walkthroughs for a beginner when it comes to interfacing with the RS232 ports on a 5500PACA pascal unit? I'm interested to know if it would be possible to interface with the C-Bus system using a Raspberry Pi over the RS232 ports. For example, I could use logic to control the Rasberry Pi to play things over Sonos, etc... I've seen that this is possible when using C-Gate installed on a machine connected to the USB port on the 5500PACA, but I'd be more interested in using the RS232 ports if possible, as the logic engine will remain active. Has anyone tried this before, or have you seen information elsewhere that may prove useful? Even if I can get to the stage where things are physically connected and I can send very basic commands would be a huge starting step - or perhaps this is a little over ambitious, so please do let me know if that is the case ;) Cheers, Ian
