SC6-TANGO • CompactPC® Serial • Intel® Atom™ E39xx Processor (APL-I SoC)
Manufacturer Mode Jumper (J-MFG)
The jumper J-MFG is used to bring the board into the manufacturer mode. This is necessary only
on board production time and should not used by customers. For normal operation the jumper
should be removed. The pin header J-MFG is not stuffed on the SC6-TANGO by default.

RTC Reset (J-RTC)
The jumper J-RTC may be used to reset certain register bits of the battery backed RTC core within
the APL-I SoC. This can be necessary under rare conditions (e.g. battery undervoltage), if the CPU
fails to enter the UEFI/BIOS POST after power on. Note that installing of jumper J-RTC will neither
set UEFI/BIOS Setup to EKF Factory Defaults nor resets the time and date register values of the
RTC (Real Time Clock). To reset the RTC core the board must be removed from the system rack.
Short-circuit the pins of J-RTC for about 1 sec. Thereafter reinstall the board to the system and
switch on the power. It is important to accomplish the RTC reset while the board has no power.
The pin header J-RTC is not stuffed on the SC6-TANGO by default.
