    I want to use third-party devices sent through the r232 to the paca command to control the lights. Can now be paca can accept a string (control commands), but I do not know how to string into a command. I try to use systemio, but without success. thanks。

    If you are wanting to control C-Bus from a third party device, there is probably no need to use a PAC. You can send serial strings directly to a PCI using the C-Bus Serial Protocol.

    If you want to use a PAC for some reason, you will need to invent your own serial protocol for use between your device and the PAC.

    This depends on whether you have any control over the strings from the third party device.

    If you want C-Bus to respond to predefined strings from the third party device, then the PAC is what you need.

    You would need to read the strings from the serial buffer into a string variable, parse the string to look for the known commands, and then call the appropriate logic functions (eg SetLightingLevel) for whatever command string is found.

    If none of this makes sense to you, then you should probably read through the tutorials and examples in the Logic Help file.
