3.2.2.2 Jumper Configurations

The following table describes the functionality of the jumpers.

Table 3-14. Jumper Configuration
Jumper	Label	Default Setting	Function
J2	AC Voltage selection	230V_AC position	AC mains input voltage range selection⁽¹⁾.
J8	3V3_PL360	Closed	3V3 current measurement for PL360 device.
J14	ERASE	Open	SAM4CMS Flash memory code erase (closed = erase).
J16	V_DD	Closed	V_DD voltage selection, 12V (open = 16V).
J17	3V3	Closed	3V3 current measurement power rail.
J21	V_DDIN	Closed	V_DDIN current measurement for PL360 device.
J22	V_{DDIN_AN}	Closed	V_{DDIN_AN} current measurement for PL360 device.
J23	V_DDIO	Closed	V_DDIO current measurement for PL360 device.

Note:

When mains is 230V_AC ±10% voltage range sets a single 5.08mm pitch jumper placed on the middle position of J2 header, see Figure 3-13. When mains is 115V_AC ±10% voltage range set two 5.08mm pitch jumpers placed on J2 header, see Figure 3-14.

DANGER: Mains voltage range selection jumper must be always manipulated before connecting the board to the mains.
