main communication port of Renogy Communication Hub.
RV-C Communication
Renogy ONE M1 can communicate with other REGO devices and monitoring devices, enabling
safe operation, smart control, remote monitoring, and programmable settings.
The RV-C communication wiring varies depending on the connection network topology. Both
backbone and daisy chain topologies are supported.
█
Backbone Topology
Some RV manufacturers have a pre-installed RV-C bus running through the RV. Please check
the RV user manual and make sure that the first and last Drop Tap on the RV-C bus has a
built-in 120Ω termination resistor. In this way, Renogy ONE and other REGO devices can be
connected to the RV-C bus for communication with the Backbone topology.
If you need to use the backbone topology for communication connections, please contact us
through renogy.com/contact-us/.

If a RV-C bus is pre-installed in the RV, check the network wiring diagram provided by the RV
manufacturer and follow the backbone topology for the RV-C communication connections.

If you are unsure whether the RV-C bus has built-in 120Ω terminal resistors after reading the
RV user manual, you can call the RV manufacturer.
z
If there is no built-in 120Ω termination resistors on the RV-C bus, Renogy ONE and other
REGO devices will not be able to communicate properly. Please use the daisy chain
topology for communication connections.
When it is determined that a backbone topology can be used for communication connections,
the appropriate communication cable must be selected for the connection based on the actual
usage.
