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.

Note 1: The internal DIP Switch functions for Multi-Master units differ slightly from the Single Master units shown (see page 7).
*Note 2: For units purchased after February 1, 2006, the settings of SW1_3 are reversed than for the settings shown on the
diagrams above. ; Set SW1_3 to the Left (On) for Master and to the Right (Off) for Slave, see notes1 & 2 on page 6. (Units
bought prior to February 1, 2006 hold the same settings as shown above)
