Installation Example & RS-232 Virtual Connection
To install a multi-drop bus topology, follow the example below. The SCADA Host controller is connected
to the Master unit (TC2200), and four RTUs are connected to Slave units (TC2201). Notice the fiber cable
from each unit's optic "TxA" (on the right side) is connected to the next unit's optic "RxA," while each unit's
optic "TxB" (on the left side) is connected to the next unit's optic "RxB." In this example, the "RxA" on
the Master unit and "RxB" on the last Slave unit (End unit) should be disabled.
