1C. C-Bus Hardware

A network bridge consists of two functionally and electrically independent systems. Each system

consists of a communication interface and microcontroller, powered by the ELV C-Bus power from the

networks to which it is connected.

Each Network Bridge provides optically isolated communication between sub-networks, so the

reliability of the overall system will not be impaired by introducing bridges. Refer to the illustration in

Figure 2

NOTE *The Multipoint to Multipoint Interrogation (MMI) Wired C-Bus uses a status

reporting system (known as an MMI), which provides automatic detection and

correction of discrepancies between the states of grouped inputs and outputs.

This status reporting occurs at periodic intervals. Increasing the frequency of

status reporting decreases the response time in which errors are corrected.

However, it increases the amount of network communication trafﬁc. If different

status report values exist in the same network, the smallest value is used. The

default value is 3 seconds.
