Other Parts Discussed in Thread: MSP430F2416
Hi,
My customer need assistance.
We designed a PCB with AFE4490 and MSP430F2416 controller.
When the board is connected to the SpO2 simulator we get correct SpO2 readings. But, when it is placed on a patient with low SpO2 the readings are always higher than 90%
The notable issue with our board is the INN, INP, TXN and TXP are not connected to same DB9 pins as shown in the AFE4490 development guide
INN to Pin 9
INP to Pin 5
TXN to Pin 2
TXP to Pin 3
Please help. Thanks.
