Hi,
The resistors below were removed according to the datasheet so that there could be external SPI communication with an MCU (Arduino) but since their removal the LEDs do not light up anymore, there is no current for the DB9 cable that powers the sensors.
R26 -> Pin 28 of the AFE (ADC_RDY);
R29 -> Pin 27 of the AFE (STE);
R31 -> Pin 26 of the AFE (SIMO);
R33 -> Pin 25 of the AFE (SOMI);
R35 -> Pin 24 of the AFE (CLK);
R37 -> Pin 23 of the AFE (PD_ALM);
R39 -> Pin 22 of the AFE (LED_ALM);
R38 -> Pin 21 of the AFE (DIAG_END);
R42 -> Pin 20 of the AFE (AFE_PDNZ);
What could have happened ?
What do I have to do ?
thank you.
