RGU-to-RGU (R2R) Communications
If more than one RGU is in the parallel configuration, an
RGU-to-RGU (R2R) communications link will be used to transmit
current commands and status information from the master unit to the
slave unit(s). The fiber optic cables for R2R communications will be
coiled in the slave RGUs.
When working with the fiber optic cables, please note the precautions
in Figure 15.7.

Wiring Guidelines
Figures 15.8 and 15.9 show the routing path and connection scheme
that should be used when connecting the R2R fiber optic cables.
