  • pins 4 and 5 of power connector (J2) must be shorted
  • pin 2 of power connector (J2) must go to to SUT's PSU_ON pin (green line); PS_OK is no longer used and MCU pin must be configured as pullup input
  • ethernet controller chip enable MOSFETs (IC6 / IC9) omitted; pins 2 and 3 must be shorted
  • indicator lights enable MOSFET (IC16) omitted; pins 2 and 3 must be shorted
  • OLED charge pump enable pull-up resistor (R24) omitted
  • OLED VCC MOSFET (IC5) omitted; pins 2 and 3 must be shorted, and pin 1 needs lead wire to pin 1 of OLED charge pump (IC4)
  • OLED enable MOSFET (IC3) omitted; pins 2 and 3 must be shorted
  • SUT power and reset MOSFETs (Q2 / Q3) must be held high for >=100ms to trigger
  • indicator lights current limiting resistor (R58) should be replaced with 10k resistor
    • future fix should use 12-13k
