Tool/software:
Hi Team,
We are using 2 Max3221 in our Design.
1) Max3221 - Console UART - 3 Pin (RX,TX, GND)
2) Max3221 - RS232
When we perform loopback test (RX/TX pins shorted)- Console UART is passing, while other one with RS232 is failing.
Following are the Schematics snapshots for the same.
We tried to Signal Probe both of them - For Console UART - By default state is low while for RS232 on its high, Attaching the snapshot.
ROUT_P9_SignalPROBE
What can be wrong here?
