Is MXP UART.RX 5v tolerent

[Joe Ross]

Sorry, it's spread across two documents. In the User manual, page 9 it says that the MXP uart are electrically the same as DIO lines.
In the specifications, it shows that DIO are 5V compatible input.

If you have further confusion, I'd suggest asking NI.

Ok, I see it, thanks.

For anyone else who might be hesitant to try this, I went ahead wired the RoboRio's RX to the Arduino's TX and both functioned as expected and I was able to transmit data across the serial line.

Thanks for your help.
