National Instruments PXIe-7858R PXI R Series Reconfigurable I/O Module
The PXIe-7858R (Part number: 784147-01) is an R Series Reconfigurable I/O Module developed by National Instruments. This module provides 8 analog inputs, each with a data sampling rate of 1 MS/s and 16-bit resolution. Each input has AI+ and AI- pins for differential voltage signals. For single-ended measurements, either AIGND (Referenced Single-Ended mode, RSE) or AISENSE (Non-Referenced Single-Ended mode, NRSE) can be used.
The NI PXIe-7858R additionally has 8 analog outputs, also with a 1 MS/s sampling rate and 16-bit resolution. Each output consists of an AOGND pin and an AO pin, enabling users to generate signals for external devices. This module offers 48 digital I/O channels with software-configurable voltage levels ranging from 1.2 V to 3.3 V. These channels can be configured as either input or output. All digital I/O channels support frequencies up to 80 MHz. The digital I/O lines connect directly to the FPGA via buffers, allowing for high-speed control and flexible logic implementation. However, external protection is required when interfacing with high voltages, as the module does not have built-in overcurrent or overvoltage protection for digital I/O.
The module is equipped with a Xilinx Kintex-7 325T FPGA, allowing users to implement custom logic for real-time processing. It has 16,020 kbits of embedded block RAM and 512 MB of onboard DRAM. The PXIe-7858R also features two 68-pin VHDCI I/O connectors for flexible interfacing. The device operates using the NI-RIO driver software, which is compatible with software packages such as LabVIEW, the LabVIEW Real-Time Module, and the LabVIEW FPGA Module. The FPGA provides precise control over I/O timing, enabling advanced applications such as custom protocol communication, sensor simulation, and high-speed control. The module also supports multi-rate sampling and per-channel triggering.
The NI PXIe-7858R is designed for PXI Express (PXIe) Peripheral Slots, ensuring high-bandwidth data transfer within a PXIe chassis. It 0.36 lbs. and has physical dimensions of 7.3 × 6.8 × 1.4 inches.

National Instruments PXIe-7858R Frequently Asked Questions
Question: Which DIO connector should be used with the NI PXIe-7858R?
Answer: The NI PXIe-7858R uses two 68-pin VHDCI connectors. Depending on your setup, you may use the SHC68-68-RDIO or SHC68-68-RMIO cables to connect to accessories like the NI 6583 or NI 6585. Verify compatibility based on your application needs.
Question: What software and drivers must be on the host computer before installing the PXIe-7858R?
Answer: Before installing the PXIe-7858R, you should have the following installed on your computer: LabVIEW 2016 or later, LabVIEW Real-Time Module 2016 or later, LabVIEW FPGA Module 2016 or later, and NI R Series Multifunction RIO Device Drivers 2016 or later.
Question: I’ve installed the PXIe-7858R, but the device is not showing still. What should I do?
Answer: If the PXIe-7858R does not appear after installation, try the following steps:-Refresh the device list in MAX by pressing F5.
-Check physical installation – ensure the module is properly seated in a compatible PXI Express (PXIe) Peripheral Slot.
-Verify driver installation – confirm that the NI R Series Multifunction RIO Device Drivers (August 2016 or later) are installed.
-Check chassis recognition – make sure your PXIe chassis is detected in MAX and properly configured.
-Reboot the system and try again.
If the issue persists, refer to the troubleshooting section of the PXIe-7858R user manual or visit ni.com/support.
