◆ Network Termination
The two ends of the MEMOBUS/Modbus network line have to be terminated. The converter has a built in termination
resistor that can be enabled or disabled using DIP switch S2. If a converter is located at the end of a network line, enable
the termination resistor by setting DIP switch S2 to the ON position. Disable the termination resistor on all slaves that are
not located at the network line end.
To set the DIP switch, use tweezers or a tool with a tip width of approximately 0.8 mm.
