Echelon Lumewave CRD 3000 Street Light Bridge - Manual (Page 29)

Street Light Bridge Integrator’s Guide 19
Note that the Segment Controller does not share a power line connection with the
luminaires on the other side of the RF bridge; the CRD 3000 Street Light Bridge
modules forward all communications between the two network segments.

Extending a Basic Installation
A single CRD 3000 Street Light Bridge module can communicate with more than
one companion CRD 3000 Street Light Bridge module to define a more complex
configuration. Figure 7 on page 20 shows an extension to the configuration
shown in Figure 5 (a European installation is not shown, but can be extended in
the same way). A single CRD 3000 Street Light Bridge module communicates
with three CRD 3000 Street Light Bridge modules to further extend the range of
the Segment Controller and provide communications to a greater number of
luminaires.
Communications between the Segment Controller and the network segments in
the foreground (the bottom of Figure 7) connect to the Segment Controller’s
network segment through an RF hop.
