EMB-DAQ2 Software Installation
Software Installation Guide for EMB-DAQ2
(updated on 3/19/2026)
Requirements ​
​
- Desktop computer with an available PCIe slot (compatible with the National Instruments PCIe-6321 card)
- Windows® operating system supported by MATLAB/Simulink Desktop Real-Time
- MATLAB® R2013b or later
- Simulink®
- MATLAB Coder™
- Simulink Coder™
- Simulink Desktop Real-Time™â€‹â€‹
Step 1: Install NI-DAQmx (driver package)
​​​
- Step 1a
Download the latest NI-DAQmx driver from National Instruments.
​
- Step 1b
Run the installer and follow the on-screen instructions.
​
- Step 1c
Reboot the computer if prompted.
Step 2: Install the NI PCIe-6321 Card
​​​​
- Step 2a
Turn off the desktop computer and disconnect power.
​
- Step 2b
Remove the computer case side panel.
​
- Step 2c
Locate an available PCIe slot and remove the corresponding rear slot cover (if needed).
​
- Step 2d
Carefully insert the NI PCIe-6321 card into the PCIe slot, pressing firmly until fully seated.
​
- Step 2e
Secure the card to the chassis using the retaining screw.
​
​- Step 2f
Reinstall the case panel.
​
- Step 2g
Reconnect power and boot the computer.
​
Do not plug the PCIe cable to the EMB-DAQ2 yet!
​
Step 3: NI MAX - Check Board
​​​
- Step 3a
Open NI MAX (Measurement & Automation Explorer).
​
- Step 3b
Under “Devices and Interfaces,” confirm that the PCIe-6321 appears.
​
- Step 3c
Our EMB-DAQ2 has a CB-68LPR connector block from NI internally.​
​
- Step 3d
Run a self-test to verify proper installation.
​
- Step 3e
Turn off the desktop computer and connect the PCIe cable to the EMB-DAQ2. Handle the computer and EMB-DAQ2 connectors carefully, as they are delicate and the NI cable is stiff.
​​
​​​​
Step 4: MATLAB/Simulink Desktop Real-Time Kernel Install
​​​
- Step 4a
In the MATLAB® command window, type: sldrtkernel -install
​
- Step 4b
Test by running the "Real-Time Van der Pol Simulation" example from Simulink Desktop Real-Time.

​
- Step 4c
This example should run properly before attempting to interface with the EMB-DAQ2 and running our EMB examples.
​​
​
Your EMB-DAQ2 system is now ready for high-performance real-time control using MATLAB and Simulink with Simulink Desktop Real-Time™.
