American Automatrix Corporation (AAM) introduced the PUP protocol in 1987. PUP stands for Public Unitary Protocol. It was intended to be used as a standard for many different Building Management System (BMS) manufacturers. As far as I know only AAM actually used this protocol in their Solo line of controllers so PUP is synonymous with AAM. AAM placed the protocol and the guidelines in the public domain.

I developed this Python Implementation of PUP to allow a Beaglebone Black to communicate via RS-485 to AAM solo controllers such as the DX-1, GX-1, GC-1, HX-1, TX-1, TC-1, MC-1 and a few others. Since it is Python it should work with any operating system that can use Python and a serial port. You will likely need a serial to RS-485 converter or a USB to RS-485 converter to make communication possible.

This implementation is not complete but it is functional. I have developed a much more complete version in posix C but that is not public yet.
