Hardwired Communication
Troubleshooting
Toro® DXi controllers are capable of communication between controllers to allow
sharing of flow devices, Master Valves, pumps, as well as communication to Sentinel
WMS central software. Controllers share communication via a hardwired connection.
The hardwired communication is made via the EV-CAB-COMM cable due to its
specific direct burial and communication properties. Each controller is wired in a
daisy-chain configuration with the submaster being the starting point and the last
controller being the ending point. Controller-to-controller connections are made via
the "DXi COMM BOARD" as seen below in figure D-2.
