NI myRIO-1900 User Guide and Specifications

Figure 5 shows the analog input topology of the NI myRIO-1900.

NI myRIO-1900 Analog Input Circuitry

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.
