UPG-PK1 Upgrade Bundle I - Which UCM?

[idheath]

Hi,

I have recently purchased a \"UPG-PK1 Upgrade Bundle I\" to replace my aging Comfort I system.

I have received a Serial UCM and not a UCM/USB one.

What is the correct item I should receive in this upgrade bundle?

Cheers Ian

There is a transition from UCM/232 to UCM/USB so either may have been supplied in the interim. Both have the same function
