FIM UART 5V Tolerant

0 votes
From NS9215 Hardware Reference I know that all I/O are 5V tolerant. Is this true for FIM UART interface on CC 9P 9215 module?

I am asking because in my setup 9215 module restarts after some time (30 minutes) when I have serial devices connected to FIM UARTs.

The same module works without problems if serial devices are connected to ports 0 - 3.

Thanks you,
Stan

If you are using CC 9P 9215 then u shud refer to http://ftp1.digi.com/support/documentation/90000879_N.pdf
page 111. I guess you can give 3.3V...

Also have you gone through the configuration settings mentioned in

Go through Hardware reference manuals for proper config..

Is this a NET+OS/Linux/PnP firmware?
