Using the Reset Button

Pressing and releasing the Reset button restarts the processor and the FPGA.
Pressing and holding the Reset button for 5 seconds, then releasing it, restarts the processor and
the FPGA and forces the NI myRIO-1900 into safe mode. In safe mode, the NI myRIO-1900
launches only the services necessary for updating configuration and installing software.
When the NI myRIO-1900 is in safe mode, you can communicate with it by using the UART
lines on MXP connector A. You need the following items to communicate with the myRIO
device over UART:
• USB-to-TTL serial UART converter cable (for example, part number
TTL-232RG-VSW3V3-WE from FTD Chip)
• Serial-port terminal program configured with the following settings:
– 115,200 bits per second
– Eight data bits
– No parity
– One stop bit
– No flow control
