Safe Mode
When the NI ELVIS RIO CM is in safe mode, you can communicate with it by using the
UART lines on MXP connector A. You require the following items to communicate with the
NI ELVIS RIO CM device over UART:
•
USB-to-TTL serial UART converter cable (for example, part number TTL-232RG-
VSW3V3-WE from FTD Chip)
You must configure your serial-port terminal program with the following settings:
•
115,200 bits per second
•
Eight data bits
•
No parity
•
One stop bit
•
No flow control
User Button
The User Button produces a logic TRUE when depressed and a logic FALSE when not
depressed. The User Button is not debounced in hardware.
LED Indications
Power LED
The Power LED is lit while the NI ELVIS RIO CM is powered on. This LED indicates that the
power supply connected to the device is adequate.
Status LED
The Status LED is off during normal operation. The NI ELVIS RIO CM runs a power-on self
test (POST) when you apply power to the device. During the POST, the Power and Status
LEDs turn on. When the Status LED turns off, the POST is complete. The NI ELVIS RIO CM
