RHX Data Acquisition Software

The universal RHX software works with RHD USB interface boards, RHD recording controllers, and RHS stim/recording controllers. The installer will set up all necessary drivers and other dependencies.

• RHX software
  (Version 3.3.2, July 9, 2023)
  • RHX software user guide
  • Release notes
  • Windows installer
  • Mac disk image
    Note: A macOS security feature may prevent you from running the application. To bypass this, right-click (or Ctrl+click) the file and select Open, then agree to Open at the warning message.
  • Linux archive file and installation instructions
    Ubuntu 18.04.5 or later recommended. Other Linux distributions (Fedora, Mint, and Debian) have been tested successfully, though these may require further installation of supporting libraries.

  Note: This software can be run without hardware present; it will generate synthetic neural data for demonstration purposes if no Intan hardware is connected.

• RHX TCP Control documentation and examples
• RHX MATLAB realtime data transfer examples

Drivers

• USB drivers for Windows (7, 8, 10), Mac, and Linux
  These drivers should be installed before attaching Intan hardware to a computer. If you later receive an error message from our software saying 'Opal Kelly USB drivers not installed' you may need to install the Microsoft Visual C++ 2010 Redistributable Package.

Windows Installation Packages

• Intan Windows software is compatible with Windows 7, 8, or 10. If you have trouble running any Intan software under Windows, you may need to install the Visual C++ Redistributable Packages for Visual Studio 2013 and for Visual Studio 2015 from Microsoft.

RHS Stim/Recording Controller

• Stim/Recording Controller software

RHD STM32 Firmware Framework

Intan has developed open-source C code written for the STM32U5 and STM32H7 microcontroller families to facilitate control of Intan RHD2216, RHD2132, and RHD2164 chips over SPI.

All example code was developed on the commercially-available NUCLEO-U5A5ZJ-Q or NUCLEO-H723ZG development boards, which are available from many electronics distributors. Intan Technologies does not sell any MCU development boards.
