==Secondary Concentrator==
[[File:SGP+M Secondary Concentrator.png|thumb|Secondary Concentrator]]
The secondary Secondary Concentrator houses 12 Metering Modules, a CPU/Radio (metal box on the right) and a main MCCB. The Metering Modules talk with the CPU through a shared optical interface. The CPU contains the software/harwdare to communicate with each meter and a built in radio that communicates with the Primary Concentrator PC through some proprietary FHSS stuff briefly mentioned in the manual.

The Primary Concentratoris the heart of the system. Primary and Secondary concentrators look identical from the outside (besides the fact that the PC has less wires coming out because there are no metering modules).
The PC holds inside a computer that I assume is way stronger, a radio to communicate with all the SCs around and a GPRS radio to inform power usage data to the power company.
