Can the CCGX be connected to any Multiplus or Phoenix including the smaller multi 1200?
It depends upon the firmware / hardware version if the MultiPlus.
The Phoenix is most likely VE.9bit, 18xxyyy firmware, this will not work.
19xxyyy / 20xxyyy firmware will work with limitations.
26xxyyy / 27xxyyy firmware is current and will work.
Below is a link to a document explains the VE,Bus versions.
