Synchronization using BI signal
(iii)
When accurate1Hz square-wave can be supplied as a reference clock, the clock function can
make the time synchronization. The 1Hz square-wave is transferred using a binary input
circuit (BI).
Example of time synchronization via BI circuit
Figure 5.7-7 exemplifies that the 1Hz square-wave is provided via the BI1 circuit†.

†Note: The BI1 circuit is just used for the explanation; hence, an actual BI circuit should
be selected in accordance with wiring cables. For more information of the BI
circuit, see Chapter
