4.2 Test Procedure

  1. Ensure the switches SW1 (EN1) and SW2 (EN2) are in the “OFF” position.
  2. Ensure the shunt jumper for JP1 is set 3-pin to 4-pin (Med).
  3. Apply appropriate V5IN voltage to V5IN and V5IN_GND terminals.
  4. Apply appropriate VIN voltage to VIN and VIN_GND terminals.
  5. Turn on SW1 (EN1). The CH1-output will start up.
  6. Turn on SW2 (EN2). The CH2-output will start up.
