Analog Input Channels
The NI myRIO-1900 has analog input channels on myRIO Expansion Port (MXP) connectors A
and B, Mini System Port (MSP) connector C, and a stereo audio input connector. The analog
inputs are multiplexed to a single analog-to-digital converter (ADC) that samples all channels.
MXP connectors A and B have four single-ended analog input channels per connector, AI0-AI3,
which you can use to measure 0-5 V signals. MSP connector C has two high-impedance,
differential analog input channels, AI0 and AI1, which you can use to measure signals up to
±10 V. The audio inputs are left and right stereo line-level inputs with a ±2.5 V full-scale range.

Analog Output Channels
The NI myRIO-1900 has analog output channels on myRIO Expansion Port (MXP) connectors
A and B, Mini System Port (MSP) connector C, and a stereo audio output connector. Each
analog output channel has a dedicated digital-to-analog converter (DAC), so they can all update
simultaneously. The DACs for the analog output channels are controlled by two serial
communication buses from the FPGA. MXP connectors A and B share one bus, and MSP
connector C and the audio outputs share a second bus. Therefore, the maximum update rate is
specified as an aggregate figure in the Analog Output section of the Specifications.
MXP connectors A and B have two analog output channels per connector, AO0 and AO1, which
you can use to generate 0-5 V signals. MSP connector C has two analog output channels, AO0
and AO1, which you can use to generate signals up to ±10 V. The audio outputs are left and right
stereo line-level outputs capable of driving headphones.
Caution Before using headphones to listen to the audio output of the
NI myRIO-1900, ensure that the audio output is at a safe level. Listening to
audio signals at a high volume may result in permanent hearing loss.

Converting Raw Data Values to Voltage
You can use the following equations to convert raw data values to volts:
V = Raw Data Value * LSB Weight
LSB Weight = Nominal Range ÷ 2
ADC Resolution
where Raw Data Value is the value returned by the FPGA I/O Node,
LSB Weight is the value in volts of the increment between data values,
Nominal Range is the absolute value in volts of the full, peak-to-peak nominal range
of the channel,
and ADC Resolution is the resolution of the ADC in bits. (ADC Resolution = 12.)
•For AI and AO channels on the MXP connectors,
LSB Weight = 5 V ÷ 2
12
= 1.221 mV
Maximum reading = 4095 * 1.221 mV = 4.999 V
•For AI and AO channels on the MSP connectors,
12
LSB Weight = 20 V ÷ 2
= 4.883 mV
Maximum Positive Reading = +2047 * 4.883 mV = 9.995 V
Maximum Negative Reading = -2048 * 4.883 mV = -10.000 V
•For Audio In/Out,
LSB Weight = 5 V ÷ 212 = 1.221 mV
Maximum Positive Reading = +2047 * 1.221 mV = 2.499 V
Maximum Negative Reading = -2048 * 1.221 mV = -2.500 V
• For the accelerometer,
12
LSB Weight = 16 g ÷ 2
= 3.906 mg
Maximum Positive Reading = +2047 * 3.906 mg = +7.996 g
Maximum Negative Reading = -2048 * 3.906 mg = -8.000 g
DIO Lines
The NI myRIO-1900 has 3.3 V general-purpose DIO lines on the MXP and MSP connectors.
MXP connectors A and B have 16 DIO lines per connector. On the MXP connectors, each DIO
line from 0 to 13 has a 40 kΩ pullup resistor to 3.3 V, and DIO lines 14 and 15 have 2.2 kΩ
pullup resistors to 3.3 V. MSP connector C has eight DIO lines. Each MSP DIO line has a 40 kΩ
pulldown resistor to ground. DGND is the reference for all the DIO lines. You can program all
the lines individually as inputs or outputs. Secondary digital functions include Serial Peripheral

UART Lines
The NI myRIO-1900 has one UART receive input line and one UART transmit ouput line on
each MXP connector. The UART lines are electrically identical to DIO lines 0 to 13 on the MXP
connectors. Like those lines, UART.RX and UART.TX have 40 kΩ pullup resistors to 3.3 V.
Use LabVIEW Real-Time to read and write over the UART lines.
