OMMUNICATIONS
The SGM1430-B meter has been designed to support the industry standard DCC
Intimate Communications Hub Interface Specification (ICHIS), which defines the
hardware interface for connectivity to CSP sourced communications hubs and the
supply levels to provide power to any mating communications hub.
The meter also supports a home area network (HAN) that establishes ZigBee
protocol connections between two devices, notably an in-home display (IHD) and
the communications hub. The HAN is established on digital radios compliant with
the IEEE802.15.4 standard.
The SGM1430-B establishes secure HAN links to the:
• CSP communications hub,
• in-home display, and
• prepayment meter interface device (PPMID).
The meter also supports a bi-directions IEC 62056-21 optical communications
port which is used during manufacture and for warranty purposes. Please note, per
NCSC requirements, the optical port is disabled for meters deployed in field
installations.
Any communications from the headend system will require support of a CSP
communications hub which will be intimately connected to the electricity meter.
Communications between the headend system and meter will be based on the UK
GB companion specification supporting remote party messages.
Communication Interfaces
The following sections describe the available communication interfaces of the
SGM1430-B meter.
ICHIS Interface
The ICHIS interface includes a 20-pin connector and an optional AC mains
connector.
