Table 40: Dip switch S1B settings overview ( 1.2 V, 1.5 V , 2.5 V, VCCIO0).
Dip switch S1B can be replaced by one resistors in the following cases:
Assembly option when resistor R17 not populated and R19 populated is equivalent to Dip switch S1B permanently set to PON.
Figure 41: assembly option: S1B = PON.
Assembly option when resistor R17 populated and R19 not populated is equivalent to Dip switch S1B permanently set to FX2 PON.
Figure 42: Assembly option: S1B = FX2 PON.
