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.

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. 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.

The accelerometer samples each axis continuously and updates a readable register with the result. Refer to the Accelerometer section of the Specifications for the accelerometer sample rates. NI myRIO-1900 User Guide and Specifications | © National Instruments | 9 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 ÷ 2ADC 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 ÷ 212 = 1.221 mV Maximum reading = 4095 * 1.221 mV = 4.999 V • For AI and AO channels on the MSP connectors, LSB Weight = 20 V ÷ 212 = 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, LSB Weight = 16 g ÷ 212 = 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 10 | ni.com | NI myRIO-1900 User Guide and Specifications Interface Bus (SPI), I2C, pulse-width modulation (PWM), and quadrature encoder input. Refer to the NI myRIO software documentation for information about configuring the DIO lines. Figure 7. DIO Lines <13..0> on MXP Connector A or B +3.3 V 40 kΩ FPGA Bus Switch DIO<13..0> Figure 8. DIO Lines <15..14> on MXP Connector A or B +3.3 V 2.2 kΩ FPGA Bus Switch DIO<15..14> Figure 9. DIO Lines <7..0> on MSP Connector C FPGA Bus Switch DIO<7..0> 40 kΩ When a DIO line is floating, it floats in the direction of the pull resistor. A DIO line may be floating in any of the following conditions: • when the myRIO device is starting up • when the line is configured as an input • when the myRIO device is powering down You can add a stronger resistor to a DIO line to cause it to float in the opposite direction. 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. NI myRIO-1900 User Guide and Specifications | © National Instruments | 11 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 Using the Wireless Button and LED For information about using the Wireless button, go to ni.com/info and enter the Info Code myriowirelessbutton. For information about using the Wireless LED, go to ni.com/info and enter the Info Code myriowirelessled. Using Button0 Button0 produces a logic TRUE when depressed and a logic FALSE when not depressed. Button0 is not debounced. 12 | ni.com | NI myRIO-1900 User Guide and Specifications Understanding LED Indications Power LED The Power LED is lit while the NI myRIO-1900 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 myRIO-1900 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 myRIO-1900 indicates specific error conditions by flashing the Status LED a certain number of times every few seconds, as shown in Table 4. Table 4. Status LED Indications Number of Flashes Every Few Seconds Indication 2 The device has detected an error in its software. This usually occurs when an attempt to upgrade the software is interrupted. Reinstall software on the device. 3 The device is in safe mode. 4 The software has crashed twice without rebooting or cycling power between crashes. This usually occurs when the device runs out of memory. Review your RT VI and check the memory usage. Modify the VI as necessary to solve the memory usage issue. Continuously flashing or solid The device has detected an unrecoverable error. Contact National Instruments. LEDs 0-3 You can use LEDs 0-3 to help debug your application or easily retrieve application status. Logic TRUE turns an LED on and logic FALSE turns an LED off. Using the USB Host Port The NI myRIO-1900 USB host port supports Web cameras that conform to the USB Video Device Class (UVC) protocol as well as machine vision cameras that conform to the USB3 Vision standard and are USB 2.0 backward compatible. The NI myRIO-1900 USB host port also supports Basler ace USB3 cameras. The NI myRIO-1900 USB host port also supports USB Flash drives and USB-to-IDE adapters formatted with FAT16 and FAT32 file systems. LabVIEW usually maps USB devices to the /U, /V, /W, or /X drive, starting with the /U drive if it is available.
